Internet Of Things Security
Apparati, methods, and computer-readable media for improving the security of communications networks. An embodiment of the present invention is a system for enabling smart devices (1401, 1402, 1403) to communicate with each other over a network (1450) without human intervention. The system comprises at least two bidirectional smart devices (1401, 1402) adapted to send and receive messages (1460) over the network (1450). Each smart device (1401, 1402) is coupled to the network (1450) via a bidirectional intelligent chip, logic device, or smart device (1411, 1421). In message sending mode, intelligent chip, logic device, or smart device (1411) appends an identifier (1417) to each message (1460) emanating from its associated sending smart device (1401). The identifier (1417) comprises a fixed portion (1415, 1416) uniquely identifying the associated sending smart device (1401), and a variable portion (1414) containing a time having a secret random starting point. The receiving intelligent chip, logic device, or smart device (1421) invokes a module (1423) contained within each intelligent chip (1411, 1421) configured to screen incoming messages (1460), by validating both the fixed and variable portions of the identifier (1417).

FIELD OF THE INVENTIONThis invention relates to secure data transactions involving smart devices, communicating between and among themselves without human intervention. Very high levels of security are achieved without the use of encryption, PINs, or passwords.
BACKGROUND ARTThe following background information may present examples of specific aspects of the prior art (e.g., approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied.
Some aspects of the prior art include, for example, a biometric sensor built into a smart card; a smart device application program that encrypts message content from a smart device to its controlling institution; and certain applications that can be accessed by PINs (Personal Identification Numbers).
Other item of prior art include key ring devices used for assorted security or operational reasons, for example, a key ring device that computes a onetime password synchronized with a central site computer, and a key ring device used to convert wireless transmission to a second type of signal.
Mobile communication devices increasingly are used for performing operations associated with privileged access, such as financial transfers of funds. A lost, stolen, and/or compromised unsecured mobile communication device may result in significant harm to users and/or institutions. If the device is lost or stolen, the security device may be successfully manipulated by a thief, the communications may be overheard by unwanted people, and fraudulent downloads may be made.
These traditional security techniques leave room for more optimal and inspired approaches, such as those described in this patent application.

An embodiment of the present invention is a system for enabling smart devices (1401, 1402, 1403) to communicate with each other over a network (1450) without human intervention. The system comprises at least two bidirectional smart devices (1401, 1402) adapted to send and receive messages (1460) over the network (1450). Each smart device (1401, 1402) is coupled to the network (1450) via a bidirectional intelligent chip, logic device, or smart device (1411, 1421). In message sending mode, intelligent chip, logic device, or smart device (1411) appends an identifier (1417) to each message (1460) emanating from its associated sending smart device (1401). The identifier (1417) comprises a fixed portion (1415, 1416) uniquely identifying the associated sending smart device (1401), and a variable portion (1414). The receiving intelligent chip, logic device, or smart device (1421) invokes a module (1423) contained within each intelligent chip (1411, 1421) configured to screen incoming messages (1460), by validating both the fixed and variable portions of the identifier (1417).
The present invention is illustrated by way of example, and not by way of limitation, in the accompanying drawings, in which like reference numerals refer to similar elements.
Embodiments of the invention are discussed below with reference to the Figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only, as the invention extends far beyond these limited embodiments. For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments that are described and illustrated. There are numerous modifications and variations of the invention that are too numerous to be listed, but that fit within the scope of the invention.
It is to be further understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications described herein, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention.
Singular words should be read as plural and vice versa, and masculine as feminine and vice versa, where appropriate. Alternative embodiments do not necessarily imply that the two or more embodiments are mutually exclusive.
As used in this specification including claims, the singular forms “a,” “an,” and “the” include the plural reference, unless the context clearly indicates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements, and includes equivalents thereof known to those skilled in the art. Similarly, as another example, a reference to “a step” or “a means” is a reference to one or more steps or means, and may include sub-steps and subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than a logical “exclusive or”, unless the context clearly indicates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood, unless the context clearly indicates otherwise.
Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein may be used in the practice or testing of the present invention. Structures described herein are to be understood also to refer to functional equivalents of such structures.
From reading the present disclosure, other variations and modifications will be apparent to persons skilled in the art. Such variations and modifications may involve equivalent and other features which are already known in the art, and which may be used instead of or in addition to features already described herein.
Although claims in this application have been formulated to particular combinations of features, it should be understood that the scope of the disclosure of the present invention also includes any novel feature or any novel combination of features disclosed herein, either explicitly or implicitly or any generalization thereof, whether or not it relates to the same embodiment as presently claimed in any claim, and whether or not it mitigates any or all of the same technical problems as does the present invention.
Features which are described in the context of separate embodiments may also be provided in combination in a single embodiment. Conversely, various features which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination. Applicants hereby give notice that new claims may be formulated to such features and/or combinations of such features during the prosecution of the present application or of any further application derived therefrom.
References to “one embodiment,” “an embodiment,” “example embodiment,” “various embodiments,” etc., indicate that the embodiment(s) of the invention so described may include a particular feature, structure, or characteristic, but do not imply that every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment,” or “in an exemplary embodiment,” do not necessarily refer to the same embodiment, although they may.
As is well known to those skilled in the art, many careful considerations and compromises typically must be made when designing for the optimal manufacture of a commercial implementation of any system, and in particular, the embodiments of the present invention. A commercial implementation in accordance with the spirit and teachings of the present invention may be configured according to the needs of the particular application, whereby any aspect(s), feature(s), function(s), result(s), component(s), approach(es), or step(s) of the teachings related to any described embodiment of the present invention may be suitably omitted, included, adapted, mixed and matched, improved, and/or optimized by those skilled in the art, using their average skills and known techniques, to achieve the desired implementation that addresses the needs of the particular application.

Some embodiments of the present invention will be described which provide means and methods for a secure communication system. Secure communication systems include a Smart Device 102 with applications for communicating and interacting with a SPARC Security Device 104, a communication system that enables secure communications between a SPARC Security Device 104 and external entities to secure a communication system. Secure communication protocols use a transaction identifier for protecting transmitted and received return information.
The system will now be described in detail with reference to the drawing Figures.
Communication system 100 includes an Application Controlling Institution (ACI) 101, a Smart Device (SD) 102, and a SPARC (Smart Process for Applications and Remote Control) Security Device (SSD) 104. The SPARC Security device (SSD) 104 is provided by the Application Controlling Institution (ACI) 101 to a customer, typically when the customer orders his or her first ACI controlled software application. Alternatively, SSD 104 may be provided by a third party as an industry service. The SSD 104 is configured to match the communications protocol used by the customer's Smart Device (SD) 102. At the time of SSD 104 installation, the ACI 101 provides the initial data load of the SSD 104, including an assigned unique SSD Unit Identifier, which is usually a number but can be an alphanumeric and/or can include special symbols, the current date, and the current time.
There may be several ACI's 101 associated with a single SSD 104. In this case, the ACI's 101 can communicate with each other via ACI to ACI messages. In these multiple-ACI embodiments, memory 112 within SSD 104 contains the designations (e.g., Credit1, Credit2, Debit, Loan, Mortgage, Transfer, Travel, POS, ATM) of the ACI's 101 that the particular SSD 104 is authorize to work with.
Each Application Controlling Institution (ACI) 101 communicates bi-directionally with Smart Device (SD) 102 via a communication channel 108. Smart Device (SD) 102 communicates bi-directionally with SPARC Security Device (SSD) 104 via a communication channel 106. Non-limiting examples for communication channels 106 and 108 include wireless, wired, and Universal Serial Bus (USB) channels. Channels 106 and/or 108 can comprise optical communications, e.g., in the form of a QR code. The optical communications do not have to be in a visible wavelength.
Each Application Controlling Institution (ACI) 101 receives, transmits, and processes information. As non-limiting examples, Application Controlling Institution (ACI) 101 may be a financial institution, an independent service, or an industry group such as MasterCard or VISA.
Smart Device (SD) 102 receives, transmits, and processes information. Examples of Smart Devices 102 include smart phones, cellular phones, tablet computers, tokens, automated teller machines (ATM), point of sale (POS) devices, transaction devices, and networks such as those belonging to Visa and MasterCard, and PayPal.
SPARC Security Device 104 receives, transmits, and processes information. SSD 104 can have multiple controls for communicating with multiple ACI's 101. SPARC Security Device 104 communicates information to its human user via an indicator portion 116, and receives information from the user via a button and/or sensor portion 110. As a non-limiting example, sensor 110 may comprise a biometric sensor, such as a fingerprint reader.
SPARC Security Device 104 also includes a memory portion 112, a processor, chip, logic device, or smart device 114, a communication portion 118, and a power supply portion 120.
Processor, chip, logic device, or smart device 114 receives information from button/sensor 110 via a communication channel 122, and is adapted to signal agreement with the transaction. Processor, chip, logic device, or smart device 114 communicates bi-directionally with memory 112 via a communication channel 124. Indicator 116 receives information from processor, chip, logic device, or smart device 114 via a communication channel 126. Processor, chip, logic device, or smart device 114 communicates bi-directionally with communication portion 118 via communication channel 128. Power supply 120 provides power to button/sensor 110, memory 112, processor, chip, logic device, or smart device 114, indicator 116, and communication portion 118, via power supply bus 130.
Button/sensor 110 accepts receipt of digital information (e.g. “on”/“off”) and/or analog sensor information from the user. Non-limiting examples for configuration of button/sensor 110 include a biometric sensor and an actuating button.
Memory 112 receives, stores, and retrieves information. Non-limiting examples of information stored include operational codes and data.
Processor, chip, logic device, or smart device 114 provides, receives, transmits, and processes information. Non-limiting examples of information received, transmitted, and processed include operational codes and data.
Indicator 116 provides capability for communicating information to the user. As a non-limiting example, indicator 116 may comprise a Light Emitting Diode (LED) or any other visual indicator, an audible alarm, and/or a vibrator.
Communication portion 118 provides capability for receiving and transmitting information to Smart Device 102. Non-limiting examples for communication provided via communication portion 118 include wired and wireless communication.
Power supply 120 provides power for powering the components of SSD 104. Non-limiting examples for power supply 120 include a rechargeable or other battery and an array of solar cells.
SPARC Security Device 104 constitutes a communication and processing device for creating a secure, identifiable transaction message to an Application Controlling Institution 101 (e.g., bank or other financial institution). SPARC Security Device 104 can be configured for generating a one-time identifier (“SSD Unit Identifier”) that uniquely identifies that particular SSD 104. SPARC Security Device 104 can operate to initiate an action via another device, such as one or more Smart Devices 102. SPARC Security Device 104 can communicate and process information associated with a multiplicity of applications and/or a multiplicity of Smart Devices 102. For example, SPARC Security Device 104 can interact with a user's cellular phone device 102 and with the user's tabular computing device 102. SPARC Security Device 104 contains information for supporting operation of application software programs associated with Smart Device 102.
Smart Device 102 and SPARC Security Device 104 can be configured to communicate only when geographically located within pre-established distance constraints, as specified for operation associated with communication channel 106. SPARC Security Device 104 may be an EMV (Eurocard/MasterCard/Visa) smart card or a NFC (Near Field Communications) smart card. An NFC smart card has a communication range of about 10 cm. In one embodiment, when a SD 102 moves out of range of its associated SSD 104, an alarm is generated in the SD 102 and/or SSD 104. This alarm may be an audible alarm, a visual alarm, and/or a vibration. In another embodiment, any activation of a SD 102 automatically triggers activation of the associated SSD 104.
SPARC Security Device 104 contributes message content to messages assembled for communication from Smart Device 102 to Application Controlling Institution 101.
SPARC Security Device 104 and associated processes provide secure communications based upon the interaction of the two distinct devices, Smart Device 102 and SPARC Security Device 104, needed to complete a transaction with Application Controlling Institution 101.
The combination of Smart Device 102 with SPARC Security Device 104 provides a secure two-device method for preventing misuse or unauthorized use (e.g., fraudulent message replay, counterfeiting, etc.) of a lost or stolen Smart Device 102. Other devices aside from SPARC Security Device 104 are not capable of providing the required current value of the information to Smart Device 102 that SPARC Security Device 104 is capable of providing. Additional security is provided by the fact that Smart Device 102 is not capable of generating the ACI-required information associated with SPARC Security Device 104 (i.e., the unique SSD Unit Identifier) to Application Controlling Institution 101 without first receiving it from the SPARC Security Device 104 (see step 314 in
The two device interaction and processing associated with Smart Device 102 and SPARC Security Device 104 replace the identification portion (typically, the user's account number) of transaction information used in the prior art with information valid for just a single transaction. Said information is typically reconstituted to an unencrypted value, avoiding the need to provide the cumbersome key management that is associated with encryption. For the communication between Smart Device 102 and Application Controlling Institution 101, the user's real account number associated with a user account is replaced by a one-time identifier (SSD ID), which comprises the unique SSD 104 Unit Identifier plus a one-time Transaction Number (TN). This one-time identifier (SSD ID) offers the following advantages:
-
- 1. The content of each substantive message becomes meaningless to those intercepting said message.
- 2. When a message is downloaded from ACI 101 to SD 102, SD 102 can use the SSD ID to screen out fraudulent messages.
- 3. Someone intercepting a message cannot use the information in the message to generate a fraudulent message, because the interceptor does not know the underlying algorithm that was used to generate the TN (transaction number).
The TN is always generated by the ACI 101. The reason for this precaution is to prevent a thief from being able to figure out the algorithm used to generate the TN by: 1) signing up for the SPARC Security Solution described herein; and 2) downloading a SPARC software application that can contain recoverable information regarding calculation of the TN.
Memory 112 includes at least two registers, one containing the unique SSD 104 Unit Identifier and the other containing the TN. Optionally, memory 112 can also comprise one or more of the following registers associated with additional fields, e.g., date, usually the current date; time, usually the current time; ACI 101 identifier, in case more than one ACI 101 is associated with the SSD 104; and one or more additional fields designating subject matter, application, transaction type, etc. The combination of these fields, when combined with the TN generated by the ACI 101, becomes the temporary one-time identifier (“SSD ID”) that replaces the user's true account number for security purposes. Each ACI 101 maintains a database with a corresponding set of registers for each user account. Verification of the SSD ID is performed by ACI 101 checking for agreement between the various components of the SSD ID of the incoming message and the components of the SSD ID stored within the ACI 101.
When there is an ACI 101 field in the SSD ID, an application in the SD 102 can tell the SSD 104 which ACI 101 to work with. Alternatively, the SSD 104 can itself determine which ACI 101 to work with, by consulting a pre-established table within the SSD 104. In this embodiment, SSD 104 can deal with multiple ACI's 101 directly, without having to designate a primary ACI 101. If there were no ACI 101 field in the SSD ID, one ACI 101 is designated as the primary ACI 101, and coordinates communications between or among any other ACI's 101 that may be part of the system.
Any and all of the SPARC Security Device 104 parameters can be made to be programmable. Such parameters can include the allowable response time before timing out, loss of an NFC signal, the range of allowable operation, etc.
An SSD 104 may be enabled to communicate using several different communications protocols, such as NFC, Bluetooth, and/or WiFi.
An ACI 101 can issue several cards to the same user. These cards can be debit cards, gift cards, loyalty cards, and/or prepaid cards. The SSD ID can include a function or card field to enable the ACI 101 to distinguish among the various card holdings for the specific transaction.
Assuming that ACI 101 successfully verifies the bona fides of the incoming message, the one-time transaction number (TN) is changed by the ACI 101. For security purposes, the one-time transaction number should not be simply incremented by 1, but rather changed by a more complex algorithm. Said algorithm is securely pre-stored in the ACI 101. Subsequent return messages having an incorrect value for the one-time transaction number are rejected by the ACI 101. This inhibits overheard transaction re-use and fraudulent message download. Upon receipt of a valid SSD ID that matches an SSD ID within its database, ACI 101 gains access to the associated true user account number. The ACI 101 database (which is indexed by the SSD Unit Identifier or the full SSD ID), enables ACI 101 to process the message using the true account number.
The one-time transaction number can comprise bits that represent other than numerical data, such as alphabetical or alphanumeric data. Thus, whenever the expression “TN” is used in this specification, it should be remembered that this is just a shorthand expression. A given message can have a first one-time transaction identifier, and the corresponding response can have a different one-time transaction identifier, as long as this protocol is pre-established by the sending and receiving devices. The TN serves to differentiate messages sent to and received from the ACI 101; and enables the detection of duplicate SSD 104 use, counterfeit messages, counterfeit SSD 104 use, and illegal use of lost or stolen Smart Devices 102. The number of digits comprising the TN can be expanded when the TN is changed, to reduce the possibility of successful attacks. A TN can be replaced by the ACI 101 to counteract ACI 101 database attacks, misuse, or theft.
Communication system 100 operates via interaction of Smart Device 102, SPARC Security Device 104, and the user. If Smart Device 102 and SPARC Security Device 104 are not both available to the user, the processing of and communication of information to Application Controlling Institution 101 is not performed. However, when just SPARC Security Device 104 is unavailable, the user can continue to use Smart Device 102 for other applications not associated with SPARC Security Device 104 (e.g., word processing, Internet browsing, etc.).
SPARC Security Device 104 supports a multiplicity of actuating devices 110. Non-limiting examples of actuating devices include manual, biometric (e.g., fingerprint), dual, and automatic. Furthermore, the actuating device 110 variations offer two or three factor security control, as desired by the user. Two factor authentication is an approach to authentication involving the presentation of two different kinds of evidence for verification. Two factor authentication is associated with something a user knows and something for which a user is in physical possession. Three factor authentication includes two factor authentication, with the addition of something uniquely related to the identity of a person (e.g., a fingerprint).
The interaction of SPARC Security Device 104 with each Smart Device 102 can be performed via the same communications protocol for all devices 102, or by more than one protocol.
Communication system 100 supports “bump” security applications. “Bump” comprises a software application operating via a Smart Device 102 and by a matching algorithm operating via servers connected to SD 102 via communication channel 108.
SPARC Security Device 104 supports an arbitrarily large number of software applications operating on a given Smart Device 102.
Software applications associated with Smart Device 102 and/or SPARC Security Device 104 can detect an attempt to record information communicated between the devices 102, 104.
Application Controlling Institution 101 can modify, disable, remove, or destroy software applications associated with Smart Device 102.
Smart Device 102 and SPARC Security Device 104 support message rejection by Application Controlling Institution 101, where appropriate. This support includes reprocessing and retransmitting the message, modification of an application software program, and destroying a portion (or all) of an application software program.
SPARC Security Device 104 supports maintenance of an audit trail for transactions initiated by SPARC Security Device 104 for communication by Smart Device 102 to Application Controlling Institution 101. As a non-limiting example, the audit trail can include the original SSD Unit Identifier or SSD ID. The audit trail information can be used to replace the original account identifiers for information communicated to or from Application Controlling Institution 101 to one or more audit computing devices (not shown). Audit trail information is typically used for generation of messages to Application Controlling Institution 101, as the associated information is not current with respect to the current time and message count content.
Software applications associated with SPARC Security Device 104 can be used for securing transaction messages communicated from Application Controlling Institution 101 to computing devices other than SD 102 and SSD 104. Such information transmitted by Application Controlling Institution 101 may be compared with information contained within SPARC Security Device 104.
Transmitted message content between and among the devices 101, 102, 104 can be verified for accuracy via parity checks. For example, Application Controlling Institution 101 may perform parity checks on received information. As a non-limiting example, parity checks can be performed via a Cyclic Redundancy Check (CRC).
Software applications to be run on Smart Device 102 and SPARC Security Device 104 can be securely uploaded and updated via the communication processes associated with Smart Device 102 and SPARC Security Device 104.
SPARC Security Device 104 may continue to be used in the event of a lost or stolen Smart Device 102.
In some embodiments, the functionality of SPARC Security Device 104 is performed by a second Smart Device 102 device, with the second Smart Device 102 simulating the operation of a SPARC Security Device 104 device.
In some embodiments, Smart Device 102 is configured to refuse to perform a requested action prior to configuration for operation with SPARC Security Device 104. As a non-limiting example, when an unauthorized user attempts to perform unauthorized transactions via the Smart Device 102 (e.g., a financial fund transfer), the Smart Device 102 does not communicate with external entities until configuration and communication with SPARC Security Device 104 is performed. As a non-limiting example, unauthorized telephone toll charges may be prevented via this feature. Furthermore, this feature may be configured for functions associated with Smart Device 102 in order to support monitoring for security device surveillance. This feature enables a user to monitor and control operation of Smart Device 102.
ACI 101 (or a licensed third party device) assigns the initial unique SSD 104 Unit Identifier, and a pre-established initial TN for new application acceptance, to software applications to be used on SD 102. The unique SSD 104 Unit Identifier is then communicated by SD 102 to SPARC Security Device 104 for confirmation. If confirmed, SPARC Security Device 104 signals the user, e.g., by illuminating indicator portion 116 in a pre-established manner, and requests confirming actuation by the user via button/sensor portion 110. If not confirmed by the user's actuating button/sensor 110, SPARC Security Device 104 generates an alert, e.g., a flash or other signal repeatedly illuminating indicator 116.
Smart Device 102 can use an access software application confirmation process for preventing unauthorized access to the software applications stored in SD 102. This access software application confirmation process can use a biometric actuator to confirm the user's privilege to access SD 102.
For a lost or stolen Smart Device 102 containing a valid SSD Unit Identifier, but no TN, SSD 102 is not able to create an acceptable message to ACI 101, because SD 102 does not have a valid one-time Transaction Number.
When an incorrect SSD Unit Identifier is presented to ACI 101, an ACI 101 software application detects the incorrect SSD Unit Identifier and rejects the attempted transaction.
Normally, the same human user controls both the SSD 104 and the SD 102.
Downloading a message from ACI 101 to SSD 104 requires the correct SSD 104 Unit Identifier, plus the correct one-time transaction number (TN).
An attempt to use multiple SPARC Security Devices 104 with a single Smart Device 102 results in an unusable signal received by Smart Device 102, which results in rejection (by ACI 101 and SD 102) of all messages generated by all the SPARC Security Devices 104. It would be cumbersome to have a separate SSD 104 for each software application.
SPARC Security Device 104 may take a wide variety of physical forms, including but not limited to a bracelet, a ring, a key ring device, a pin-on device, a pocket device such as a pen, a set top programmable remote control device, or any similar lightweight and compact devices. SPARC Security Device 104 may be configured such that, when its power 120 runs low, an alarm is generated. The alarm may be an audible alarm, a visual alarm, and/or a vibration of the SPARC Security Device 104. Similarly, when someone attempts to use SPARC Security Device 104 with no accompanying or available communications network, an alarm can be generated. Preferably, the alarm is kept local, but includes within its range the Smart Device 102 with which the SPARC Security Device 104 is communicating.
SPARC Security Device 104 includes a button/sensor portion 110, an indicator portion 116, a containment portion 202, and an attachment element 204.
Use of the button 110 without an SD 102 input activates a pre-specified SD 102 application software program on the corresponding Smart Device 102. Button 110 may comprise a biometric sensing actuating device. SSD 104 may not require an actuator at all; in this scenario, SSD 104 gives its SSD Unit Identifier to the Smart Device 102 automatically, as long as the distance requirement is satisfied.
Indicator 116 can have several different settings, corresponding to several different software applications.
Containment portion 202 provides mechanical containment of associated electronic and mechanical devices associated with SPARC Security Device 104. Containment portion 202 has a length 206, a height 208, and a width 210. As a non-limiting example, length 206 may be two inches, height 208 may be ½ inch, and width 210 may be ¼ inch.
Attachment element 204 provides capability for attachment of SPARC Security Device 104 to other devices. Element 204 can be, e.g., a keychain, key ring, safety pin for attachment to clothing, etc.
With reference to
Let us assume that a software application associated with Smart Device 102 wishes to request a transaction with Application Controlling Institution 101. Non-limiting examples of information communicated from Smart Device 102 to Application Controlling Institution 101 include an account identifier, an Application Controlling Institution 101 designation, transaction type, fund type requested, requested fund amount, currency type (e.g., U.S. dollars), Smart Device 102 communications address, and a transaction password for routine security.
With reference to step 304, the user of SD 102 initiates this transaction via selection of a transmit button on SD 102 or via a SEND function on the associated software application. Smart Device 102 communicates certain information to SPARC Security Device 104 over logical line 305. Non-limiting examples of this information that is communicated to SSD 104 include account identifier and transaction type.
At step 306, SPARC Security Device 104 stores in its memory 112 the received account identifier and transaction type. At step 308, SPARC Security Device 104 illuminates its indicator portion 116, signaling the user to verify that the transaction should proceed. At step 310, SPARC Security Device 104 receives an indication that its user has actuated button/sensor 110. At step 312, illumination of indicator portion 116 is terminated.
At step 314, the unique SSD Unit Identifier is sent by SPARC Security Device 104 to Smart Device 102 over logical line 315.
At step 316, Smart Device 102 receives and validates the unique SSD Unit Identifier received from SSD 104, by checking the SSD Unit Identifier against a database containing valid ones. Valid SSD Unit Identifiers are stored within SD 102 to detect attacks involving use of counterfeit SSD 104's. If SD 102 determines that the incoming SSD Unit Identifier is valid, the process continues. If not, the process terminates. Furthermore, Smart Device 102 communicates the SSD Unit Identifier and the requested transaction to Application Controlling Institution 101 over logical line 317.
At step 318, ACI 101 receives and processes this information. ACI 101 uses the SSD Unit Identifier for retrieving information from its database indexed by the SSD 104 Unit Identifier. Furthermore, ACI 101 performs a comparison of any additional received transaction information with transaction identifier information in its database in order to verify that information received over line 317 is valid. Furthermore, ACI 101 can also validate any other information received over line 317 via the date, time, identity of ACI 101, and/or subject matter fields in the SSD ID. ACI 101 then retrieves the conventional user account identifier from its database for confirming the validity of the transaction.
If ACI 101 validates the transaction, ACI 101 processes the transaction. ACI 101 prepares and communicates any relevant information to Smart Device 102 over logical line 319. As a non-limiting example, the information sent over line 319 includes the SSD ID, including the unique SSD Unit Identifier.
At step 320, Smart Device 102 validates the SSD ID, and transmits information over logical line 321 to SPARC Security Device 104 to complete the validation. Information sent over logical line 317A constitutes a copy of information sent over logical line 317, and can also be used to validate the return message from ACI 101.
At step 322, SPARC Security Device 104 completes validation of the transaction. As a non-limiting example, SPARC Security Device 104 confirms that the received unique SSD ID is correct. Then, SSD 104 communicates information over logical line 323 to Smart Device 102. As a non-limiting example, information sent over logical line 323 includes a signal that gives final authorization to Smart Device 102 to execute the transaction. As a non-limiting example, executing the transaction may include moving funds associated with a bank account.
At step 324, Smart Device 102 executes the transaction. As a non-limiting example, Smart Device 102 posts into the account of the user of SD 102 funds received from ACI 101.

In step 428, a determination for Smart Device 102 receiving the SSD Unit Identifier from SSD 104 is performed. For a determination of Smart Device 102 not receiving the unique SSD Unit Identifier in step 428, in step 430, a determination for a timeout condition is performed. For a determination of “not a timeout condition” in step 430, the execution of method 400 transitions to step 428. For a determination of receiving the unique SSD Unit Identifier in step 428, in step 438, the Application Controlling Institution 101 identifier is communicated from Application Controlling Institution 101 to Smart Device 102.
In step 440, a determination for receipt of the Application Controlling Institution 101 identifier is performed by Smart Device 102. For a determination of not receiving Application Controlling Institution 101 identifier by Smart Device 102 in step 440, in step 442, a determination for a timeout condition is performed. For a determination of “not a timeout condition” in step 442, the execution of method 400 transitions to step 440.

Use of the unique SSD Unit Identifier with the one-time Transaction Number in place of the conventional account number makes content meaningless to those overhearing the communications.
If an incorrect Transaction Number is received, the receiving entity 101, 102, 104 normally erases or destroys the message as being fraudulent, because an incorrect Transaction Number is an indication of fraud. Such a message may contain a virus or other malware. In this case, the receiving SD 102 or SSD 104 sends a notice to the ACI 101.
An incorrect value in the one-time Transaction Number indicates a fraudulent download. Any of the three types of devices 101, 102, 104 described in this secure communications system could send a message with an incorrect SSD Unit Identifier or Transaction Number. In that case, the other two devices conclude that something is awry.
The processes described herein pertaining to the SSD 104 may replace the customary bank card, PIN number, and keyboarding that one uses when withdrawing cash from an ATM (Automated Teller Machine). In these embodiments, the ATM is controlled by an ACI 101.
The combination of the SD 102 and the SSD 104 can provide identification and access control for any number of industries, including medical, retail, supermarket, government, education, student, and travel.
The SSD 104 processes described herein may be incorporated as the basis for a revenue producing insurance program, in which screening for valid messages is done by an ACI 101 or an SSD 104. In this embodiment of the present invention, SD 102 first establishes a “white list” of acceptable correspondents and/or types of messages for whom it wishes to send or receive messages. SD 102 conveys this white list to ACI 101 and/or SSD 104, which screen messages sent to SD 102 adhering to the criteria of the white list. ACI 101, for an appropriate insurance premium that it charges to the user of SD 102, insures said user that only acceptable types of messages, to or from acceptable correspondents, are sent to or received from SD 102.
In one embodiment, independent of the usage of the SSD 104, when an SD 102 is used with a magnetic stripe reader (for example, one provided by the company Square), two messages are produced by a software application within the SD 102. One of the messages corresponds to the user account number, and the other message pertains to the remaining content. “Remaining content” can comprise expiration date and/or bank number. This embodiment also can be used when two Smart Devices 102 are interacting with each other (e.g., in a chip, logic device, or smart device interface). The interaction may be by physical contact, or by proximity in the case of protocols such as NFC.
In some embodiments, the unique SSD Unit Identifier is not stored on the Smart Device 102. This is a precaution, in case the SD 102 is lost or stolen. In some embodiments, conventional user account numbers are not stored in the SSD 104, even if they are stored in the SD 102.
A message content check can be added to a message downloaded to SD 102 to detect any attempt to add a destructive program (for example, a virus) to the message. (“Downloaded” refers to a message that is received by the Smart Device 102.) In this case, the ACI 101 adds the same message content check for transaction messages that are received by SD 102. The message content check can comprise all or portions of the SSD ID and/or something else.
The Smart Device 102 may be configured to require the cooperation of SSD 104 prior to any message being sent from SD 102. This can be accomplished by means of a lockout switch on SD 102.
This security feature can be strengthened even further by means of requiring that all incoming messages to, as well as all outgoing messages from, the SD 102 require cooperation of the corresponding SSD 104. Again, this can be accomplished by a switch, or can be hard-wired into the SD 102.
In these embodiments, the SSD 104 acts like an “ignition key” for the Smart Device 102. In other words, SD 102 is useless unless SSD 104 is present. The distance requirement still has to be met. In WiFi and Bluetooth, the battery in each of the SD 102 and SSD 104 has to be functioning. In the NFC protocol, only one battery has to be functioning, in either SD 102 or SSD 104, because in the NFC protocol, the device with the non-functioning battery is powered by the RF signal over which SD 102 and SSD 104 communicate.
The SD 102 can comprise a holding buffer memory for containing incoming messages until validated by the associated SSD 104. In these embodiments, if the incoming message does not have the correct SSD ID or other code, the message is destroyed by SD 102 on the grounds that there is a high possibility that the message contains malware.
Vital data in the SD 102 may be disguised and protected from external examination if the SD 102 is lost or stolen, by adding the unique SSD Unit Identifer of the associated SSD 104 to each such vital data item.
One SSD 104 can be employed with multiple AC's 101. In these embodiments, identifiers for the ACI 101 are stored in the SSD 104. The various AC's 101 can represent different financial resources, such as Credit 1, Credit 2, Debit 1, Debit 2, Mortgage 1, Transfer 1, Travel, Point of Sale (POS), ATM (Automated Teller Machine), etc. In these embodiments, the combination of the SD 102 and the SSD 104 constitutes a payment device, which can completely replace coins, paper currency, and credit or debit cards. The several AC's 101 can share the single SSD 104 by means of sending ACI 101 to ACI 101 messages amongst themselves.
The SSD ID described herein replaces a PIN, a password, and encryption. Encryption can still be used at various places in this communications system for additional security or protection of vital data, but a downside with encryption is that it requires a relatively cumbersome key-management system.
In one embodiment, moving the Smart Device 102 out of the communications range of the associated SSD 104 causes an alarm to be activated. The alarm can be auditory, visual, and/or vibrational. In certain embodiments, any use of Smart Device 102 automatically triggers the “waking up” of the associated SSD 104.
Typically, an ACI 101 to SSD 104 message contains only the SSD ID.
The SSD 104 security scheme described herein is compatible with security concepts used successfully for nearly 50 years for bank card security, i.e., use of a central database for security decisions. This is achieved by using the unique SSD 104 Unit Identifier for transaction authorization at the ACI 101. The ACI 101 database uses the SSD 104 Unit Identifier to look up the conventional user account number for the transaction. This successfully removes the actual user account number from transmitted data.
An important alternative for the format of the SSD ID is, but not limited to, to make said format consistent with the established database number in existing ACI 101 databases, namely the ANSI x4.16-1983 (ISO 3554) Magnetic Stripe Card, Track 2 Standard. In this Standard, the SSD ID content comprises 40 digits of 5 bits each, including a parity check bit. The primary ID number is 19 digits, including ACI 101 identification and the unique SSD 104 Unit Identifier. Also included are 17 digits of additional data comprising the one-time Transaction Number, and optional fields, such as the date, time, and any sub-account designation. The remaining bits comprise control and check digits. In this Track 2 Standard, the Transaction Number is truly a number, i.e., it is not an alphanumeric expression.
The processes described herein can be said to convert the security problem to a database process. In summary:
SD 102 performs these steps:
-
- Actuate Smart Device 102 software application. Select transaction and enter amount.
- Actuate “Send” function. Send signal to SPARC Security Device (SSD) 104.
Then SSD 104 performs these steps:
-
- Receive signal. Ask user to actuate SSD 104.
- Generate or retrieve SSD Unit Identifier.
- Send SSD Unit Identifier to SD 102.
Then SD 102 performs these steps:
-
- Receive SSD Unit Identifier. Replace conventional user account number. Optionally, indicate sub-account.
- Complete transaction message and send to Application Controlling Institution 101.
Then ACI 101 performs these steps:
-
- Receive SD 102 message in its buffer.
- Access database—retrieve conventional user account number, compare SSD Unit Identifier with expected value.
- If SSD Unit Identifier is valid, process message. If not, erase transaction and notify SD 102. Prepare response.
- Update TN and prepare SSD ID; transmit reply message to SD 102.
Then SD 102 performs these steps:
-
- Receive and hold message in SD 102 buffer. Send SSD ID to SSD 104.
Then SSD 104 performs these steps:
-
- Evaluate SSD ID. If valid, advise SD 102 to process transaction. If not, destroy message.
Then SD 102 performs these steps:
-
- Process reply message content and execute transaction. Display result. Clear buffer.
It can be highly desirable to apply the SSD 104 functionality described herein to perform and safeguard “Loyalty Applications”. As used herein, a “Loyalty Application” is one which is principally used by a participating entity or a group of participating entities that share a common nomenclature, and a common set of objectives and practices; and that provide a common set of products or services, in exchange for earned income or loyalty. “Participating entities” can include, without limitation, one or more merchants, corporations, fraternal organizations, and/or nonprofit organizations. For example, the group of participating entities may be a chain of supermarkets, wherein the chain awards a bonus of $10 worth of groceries to users who purchase $200 worth of groceries at the chain in a given month. As another example, the participating entity may be a corporation that offers its employees incentive credits to use local health/wellness facilities, as a means for controlling its health care costs. As yet another example, the participating entity may be a charitable organization that wishes to make it easier for contributors to make charitable contributions to the organization.
An SSD 104 Loyalty Application can comprise the user of SD 102 and SSD 104 interacting with the process to purchase an article or to use a service so as to: (1) uniquely identify and provide the purchaser with a secure method to accept incentives offered by the entity or group of entities (including but not limited to inducements, rebates, loyalty points, or rewards from participating merchants, corporations, fraternal organizations, or nonprofit organizations, some of whom may not even be known to the user); (2) provide a purchasing or loyalty incentive based on the purchaser's or user's prior account relationship and actual account utilization with a preferred provider or group of providers, or through an ACI 101 member base; (3) capture the potential price or incentive value earned in response to selecting a Loyalty Application purchase decision or the use of a service; (4) provide the payment function associated with the selected Loyalty Application purchase or service use, and convert the potential price or loyalty/incentive value into an actual sale or use, with incentive or loyalty point capture; (5) capture the value of the Loyalty Application based transaction for future incentive or loyalty point calculation and use; (6) capture the transaction details in a database for future account activity analysis and actual purchase or procurement incentives assessment; and (7) utilize Loyalty Application specialized functionality, such as with health and educational services, so as to complete a transaction paid for by prior incentive value accumulation, or via monetization to provide a charitable donation.
The product requirements for a Loyalty Application are illustrated in
The ACIRD 81 provides a remote and interim substitute for ACI 101 functions. Examples of its use are these:
-
- 1. A local (to SD 102/SSD 104) inquiry device with access to pre-stored data, such as a supermarket shelf product identification device or compilation of gymnasium incentive point values for specified exercise levels.
- 2. A controlled/secured entry to ACIRD 81 content to observe, upload, download, or change the ACIRD 81 content.
- 3. Initiation of an ACIRD 81 action as a prelude to requiring secure ACI 101 access for a controlled/confidential transaction.
The operation of the ACIRD 81 and SSD 104 in a Loyalty Application will now be described with respect to
ACIRD 81 is a self-contained unit with its own power supply 84, logic device, chip, or smart device 86, database 85, communications module 82, and display 83. Device 81 accepts the following types of input messages: 1) An inquiry. This message activates a prepared display 83 message. The message can include a description of the item or service connected with the device 81 operation. 2) An order. This message allows the user to specify the quantity of product or service requested. 3) A change message, which allows ACIRD 81 to change the unit content and responses. 4) A remote inquiry message, requesting that activity content stored within ACIRD 81 is forwarded to the ACI 101 for record processing, inventory control, and/or preparation of summaries of services delivered.
For security purposes, ACIRD 81 has a content equivalent to that provided by an SSD 104, and includes said content with data being transferred to the ACI 101. This allows the ACI 101 to securely assess its input from a variety of SSD 104 and ACIRD 81 sources. There can be one SSD 104 for multiple ACIRDs 81.
Device 81 is usually physically located in or near the storage area for the cognizant product or service. As non-limiting examples, the ACIRD 81 can be integral to an admission acceptance or service location; integral to a manufacturing or fabrication location; integral to a direction setting location for a transportation or physical conveyance location; integrated into a communications originating location, a set top box, a smart device, a smart TV, etc.; or located at an educational or health services location, a sports event, or an entertainment venue.
FIG. 8B1 shows local operation or inquiry of an ACIRD 81 where an SSD 104 is not required for the transaction. As non-limiting examples, these are transactions where transaction data is being captured for future assessment or use, or monetization or redistribution to family members or charitable causes.
In FIG. 8B1, SD 102 initiates a transaction at step 810. At step 811, ACIRD 81 receives the transaction request, and, at step 812, accesses an appropriate database. At step 813, ACIRD 81 displays the results of the access on its display 83. At step 814, ACIRD 81 performs the transaction, in this case a redistribution of funds, and confirms the transfer to SD 102. At step 815, SD 102 displays the results of the transfer on its display. At step 816, the process ends.
FIG. 8B2 shows an example where ACIRD 81 is a particular species, namely an ATM (Automated Teller Machine) 91. At step 820, ATM 91 initiates a transaction and sends the request to SSD 104. At step 821, SSD 104 receives the requested transaction. At step 822, SSD 104 illuminates its indicator 116, or otherwise notifies its user that a transaction request is pending. At step 823, the user acknowledges the transaction request by means of actuating button or sensor 110 as previously described, or by any other means. At step 824, the processor 114 within SSD 104 enables the transaction to take place, and at step 825, the communications module 118 within SSD 104 instructs ATM 91 to process the transaction. In this example, the transaction comprises authorizing ATM 91 to dispense cash to the user of ATM 91.
At step 826, logic device, chip, or smart device 86 within ATM 91 checks to see whether the transaction may take place. In this case, for example, ATM 91 checks its store of cash to see whether enough cash is available to dispense, and checks to see whether the user of ATM 91 is authorized to receive that amount of cash on that particular day. If these verification steps are not completed successfully, the process ends at step 827 with no cash being dispensed. If, on the other hand, the verification steps do succeed, the cash is dispensed to the user at step 828. Then ATM 91 updates its database at step 829, and displays on its display 83 at step 830 a message to the user that the cash is being dispensed. The process ends at step 831.
While FIG. 8B2 has been described in terms of ACIRD 81 being an ATM 91, the method just described can be used where ACIRD 81 is a ticket dispenser for any activity requiring a ticket, such as a ride on public transportation, a theater event, a sporting event, etc. Similarly, ACIRD 81 can be a repository of loyalty information. In this embodiment, the transaction can involve the distribution of loyalty coupons to the user, and corresponding update of database 85.
FIG. 8B3 illustrates an embodiment of the present invention in which the database 85 of ACIRD 81 is updated, changed, or unloaded. In this embodiment, ACIRD 81 initiates the transaction at step 840, and sends a transaction request to SSD 104. At step 841, SSD 104 receives the transaction request, and, at step 842, SSD 104 signals its user, by any of the means previously described (such as by illuminating indicator 116) that a request has been received. When the user authorizes the transaction, he or she actuates button/sensor 110, or uses any other technique, to notify SSD 104, at step 843. At step 844, SSD 104 enables and processes the transaction request, utilizing its processor 114. At step 845, SSD 104 communicates the transaction to ACIRD 81 via its communications module 118. At step 846, ACIRD 81 receives this transaction message and accesses appropriate areas within its database 85. At step 847, ACIRD 81 implements the cognizant transfer or change using its logic device, chip, or smart device 86. At step 848, ACIRD 81 displays the transaction on its display 83. The method ends at step 849.
At step 860, SD 102 creates a transaction request and sends it to ACIRD 81. At step 861, ACIRD 81 receives the transaction request. At step 862, ACIRD 81 checks the SSD Unit Identifier that was given to it with the transaction request, and forwards the transaction request to SSD 104. At step 863, SSD 104 receives the transaction request, and, at step 864, notifies its user (by any of the means previously discussed, such as by activation of indicator 116) that a transaction request is pending. Assuming that the user desires to go ahead with the transaction, SSD 104 receives actuation from the user at step 865 via any of the means previously discussed, such as the user activating button/sensor 110. At step 866, SSD 104 authorizes and processes the transaction using its processor 114, and conveys this fact to ACIRD 81 via its communications module 118.
At step 867, ACIRD 81 opens logic within its logic device, chip, or smart device 86 to decode the transaction. If the transaction is to unload data from ACIRD 81 to SD 102, ACIRD 81 prepares instructions to accomplish this at step 868 and, at step 869, so notifies SD 102. At step 870, SD 102 stores the data it has just received from ACIRD 81 and, at step 871, displays a message to its user. The process then ends at step 872.
If, on the other hand, the transaction is to load data from SD 102 to ACIRD 81, at step 873, ACIRD 81 prepares instructions to accomplish this and sends the instructions to SD 102. At step 874, SD 102 then prepares the necessary data package and transfer instructions, and sends this to ACIRD 81. At step 875, ACIRD 81 then stores the data it has just received from SD 102. The process then ends at step 876.
At step 880, SD 102 creates a transaction request and sends it to ACIRD 81. At step 881, ACIRD 81 receives the transaction request, and at step 882 checks the SSD Unit Identifier that was given along with the transaction request. If the SSD Unit Identifier checks out, ACIRD 81 forwards the transaction request to SSD 104, which receives it at step 883 and stores it within its memory 112.
At step 884, SSD 104 sends a message to its user by any of the means previously described, such as by illuminating indicator 116, that a transaction request is pending. Assuming that the user wishes the transaction to proceed, the user actuates button/sensor 110, or notifies SSD 104 by any other means, at step 885. At step 886, SSD 104 uses its processor 114 to enable and process the transaction, and so notifies ACIRD 81 in a message that includes the unit identifier for SSD 104 as a security precaution. At step 887, ACIRD 81 processes the message and considers appropriate options that it may offer to the user of SD 102, and forwards this message to SD 102. These options can include, for example, offers to redeem loyalty points at participating merchants, or incentives to participate in a corporate wellness program. At step 888, SD 102 displays the message on its display. At step 889, SD 102 then authorizes the data transfer and sends the transfer message to ACI 101 using the SSD Unit Identifier as an index. At step 890, ACI 101 verifies the validity of the SSD Unit Identifier. At step 891, ACI 101 generates appropriate housekeeping and storage commands. At step 892, ACIRD 81 stores the data in its database.
The remaining steps in
As an example of an ACIRD 81-based transaction sample, consider a purchase environment such as purchase of a supermarket shelf item. The user brings his or her Smart Device 102 into the communications required range of the shelf item. An application within SD 102 transmits a signal to the user's SPARC Security Device 104. The SSD 104 executes the following sequence of events: 1) it interrogates ACIRD 81 (which can be physically located on the supermarket shelf) to receive a description of the shelf item, its cost, and transaction loyalty value; 2) it exercises a purchase action, supported by the SD 102; 3) it transmits the purchase transaction to the ACI 101 associated with that application, including the loyalty value of the transaction; and 4) it initiates a value transaction to the ACIRD 81, where the value transactions for a preset period are accumulated for that user for later transfer to the ACI 101. The application within SD 102 can use the value for deciding whether subsequent purchases are worth making, and for generating reports of the user's purchases.
Summary of ACIRD 81 UseIn summary, the ACI 101 processes the user's account based monetary data and/or other transactions, after assuring correct security content of the transaction messages. The ACIRD 81 processes the incentive, loyalty, or quantity related value data and transactions, again using a security identification. The content of the value data includes a broad spectrum of value factors that are selected and set by the users and participating entities prior to inclusion in the process. As in the non-ACIRD embodiments described herein, the SSD 104 provides a vital control function which prevents Smart Device 102 misuse when the device 102 is lost or stolen. As described previously, SSD 104 prevents use of overheard transmissions to steal vital transaction or identification data, provides a means to prevent downloading fraudulent applications, and allows loyalty incentive monetization programs.
Unsolicited Transactions (UTs)Up to now, we have discussed the security of a transaction originating on a Smart Device 102, and the response to this origination from an Application Controlling Institution (ACI) 101. Now, with reference to
This UT security issue is addressed by the introduction of two (typically 40 digit long) UT registers 901, 902. The first UT register 901 contains a validity identifier used to identify validly screened content that has been originated by an external communication source 906 and has been addressed to a Smart Device 102 that has subscribed to the UT service. The second UT register 902 contains a similar validity identifier that is used to re-synchronize the validly screened content if and when the message flow is interrupted for any reason.
A service entity 900, which we call here the SPARC Internet Security Corporation (SISC), contains a processor, chip, logic device, or smart device 907 that scans or otherwise receives externally-originated incoming messages that are addressed to the e-mail address of a participating Smart Device 102 (step 910 in
For contaminated messages, processor 907 preferably generates a notice to the intended recipient Smart Device 102. The notice informs the user of the recipient Smart Device 102 of his/her option to ask that the message be sent to the Smart Device 102 despite its having been declared to be “contaminated” (step 913). Contaminated messages are stored in a register 904 within SISC 900 for a preselected period (waiting time) pending the recipient's 102 reply. If a request to forward the contaminated message to the Smart Device 102 is not received by SISC 900 from the SD 102 within the specified waiting period, processor, chip, logic device, or smart device 907 destroys the contaminated message.
2. Preparing Uncontaminated Content for Communication to Smart Device 102SISC 900 maintains a register 905 of valid SSD 104 addresses, i.e., addresses of SSD 104's that are pre-authorized to participate in the UT scheme. Each uncontaminated message contains the e-mail address of the recipient Smart Device 102. Processor, chip, logic device, or smart device 907 adds an SSD UT Identifier to the message, signifying that the message has been determined by Contamination Detector 903 to be uncontaminated (step 914). The SSD UT Identifier comprises the address (or other unique identifier, such as the previously described SSD Unit Identifier) of the SSD 104 that has been pre-authorized to participate in this UT scheme by SD 102, and an optional message count. The message count facilitates detection of any overheard transmission being illegally reused. This illegal reuse can be detected by chip, logic device, smart device, or processor 907 observing that two incoming messages have the same message count. The message count is added to the SSD UT Identifier by chip, logic device, smart device, or processor 907, and is a count of the number of valid messages that have been sent to the particular Smart Device 102, regardless of the source 906. Processor, chip, logic device, or smart device 907 changes the count from message to message by applying an algorithm. The algorithm does not simply increment the count by 1 from one message to the next, as doing so would make it easier for nefarious persons to break into the system.
Processor, chip, logic device, or smart device 907 then sends the UT message with the appended SSD UT Identifier to SD 102 (step 915).
3. Receipt of a Message with SSD UT Identifier at the Smart Device 102
There are four types of messages that can arrive at the Smart Device 102.
-
- 1) Transactions that originated at the Smart Device 102 and have been returned to the Smart Device 102 by an ACI 101 with a validated SSD ID, as discussed above in conjunction with previously-described embodiments of this invention.
- 2) A UT message successfully cleared by SISC 900, with the SSD UT Identifier appended. For such a message, Smart Device 102 checks the unique SSD 104 identifier portion of the SSD UT Identifier against its internal database (step 916), and, when SD 102 determines that the unique SSD 104 identifier is valid, processes the incoming message as a valid message (step 917).
- 3) A UT message without a valid SSD UT Identifier, such as a SSD UT Identifier having a missing or invalid unique SSD 104 Unit Identfier. Smart Device 102 summarily destroys such messages as being too risky for further consideration (step 918).
- 4) Transaction content received from another Smart Device 102, such as in a bumping action. As used herein, a “bumping action” is a communication between two Smart Devices 102 that are proximate to each other, e.g., within NFC range, and that share a bumping application program. In this case, the recipient Smart Device 102 accepts or rejects the content based upon the dictates of the shared bumping application program.
If the incoming UT message flow is interrupted for any reason, such as a break in the communications link between the source 906 and SISC 900, processor, chip, logic device, or smart device 907 moves the contents of the second UT register 902 into the first UT register 901, to re-synchronize the process. Then processor, chip, logic device, or smart device 907 inserts a new validity identifier into the second UT register 902, and securely conveys the new validity identifier 902 to sources 906 that have been authorized to participate in the UT system. The new validity identifier 902 must be different than the first validity identifier 901, and can be generated by a random number generator or a random character generator, for example.
In another embodiment of the invention, all Smart Devices 102 are designed with the ability to have just Near Field Communications (NFC) or other short-range communication capability, i.e., the Smart Devices 102 are disabled from communicating with wide area networks 506, such as the Internet or other external networks. In this embodiment, Smart Device 102 is able to communicate only with its corresponding SPARC Security Devices 104. The user of a Smart Device 102 who wishes to engage in communications with the external network 506 must conduct such communications through its corresponding SSD 104.
Major advantages of this embodiment accrue from the fact that all security functions and concerns are removed from Smart Device 102. Smart Device 102 is thereby able to run all software applications in their standard form, without having to purchase, install, or run security enhanced versions of the software applications, and without having to modify existing software applications. This embodiment is particularly useful for senior citizens or others who are prone to lose or misuse their Smart Devices 102. This embodiment speeds SD 102 transactions, in that for outgoing (outgoing from the point of view of SD 102) messages, there is no need for acknowledgement messages to be sent back to the SD 102. For incoming messages to the SSD 104, unacceptable messages are screened out before reaching the SD 102. The cost of operating the SD 102 is lowered, because the SD 102 does not need to communicate with the Internet or other external network 506, eliminating any need for PINs, passwords, and/or encryption to protect such network 506 transmissions.
In this embodiment, when SD 102 wishes to send a message via external network 506, SD 102 first composes the message and sends it to its associated SSD 104. The human user of SSD 104 is alerted (e.g., via indicator 116) that an outgoing message has been presented to SSD 104, and must affirmatively take some action, such as by pressing button 110, before the message is released and relayed to external network 506. Similarly, an incoming message from external network 506 to SD 102 is first routed through the matching SSD 104, where again the human user of SSD 104 is alerted, e.g., via indicator 116. The user of SSD 104 then must take affirmative action, such as by pressing button 110, before the message is released and relayed to SD 102.
Control of Remote DevicesThe principles of the SPARC security solution that have been described above can be extended to control of remote devices 1101, as shown in
As shown in
Action Portion 1103 controls and/or measures one or more Devices 1109. Examples of Device parameters that can be controlled by Action Portion 1103 include, but are not limited to, temperature in a room or building, air flow in a room or building, lighting in a room or building, and operation of a burglar alarm. Action Portion 1103 can be instructed by Application Control Device 1102 to control one or more than one Device 1109, simultaneously or seriatim. Alternatively, Action Portion 1103 can relay to Application Control Device 1102 measurements from the Device(s) 1109 being measured. Examples of Device sensors that can be measured by Action Portion 1103 include, but are not limited to, a thermometer, a relative humidity gauge, an air flow monitor, a camera (which can be a still camera or a video camera), and an altimeter.
Action Portion 1103 typically comprises an input/output module 1132 for communicating with the Device(s) 1109, and a processor, chip, logic device, or smart device 1131 coupled to input/output module 1132 and to processor, chip, logic device, or smart device 1141.
Application Control Device 1102 is situated remotely from Remote Device 1101, and communicates with Remote Device 1101 via an electronic connection 1106. Electronic connection 1106 may comprise the Internet, in which case one or more Internet Access Points (routers) 1107 are coupled between Remote Device 1101 and Application Control Device 1102.
A long felt but unmet need in the remote control industry has been adequate security protection for the operation of such remote devices. The security problems have fallen into three general categories:
-
- 1. The remote devices can be stolen, or damaged in a natural catastrophe.
- 2. Communications between the remote device and its remote application control point are subject to being intercepted by nefarious entities.
- 3. Nefarious entities have been able to download malware into such remote devices, which has led to catastrophic results when the remote devices have been used in the operation of critical infrastructure, such as nuclear power plants.
The present invention elegantly and simply satisfies these long felt but unmet needs.
In the present invention, Security Portion 1104 is added to Action Portion 1103 of Remote Device 1101. Security Portion 1104 comprises a read-only memory 1142 containing a unique security portion identifier, which, as alluded to previously, is analogous to the unique SSD 104 Unit Identifier referred to previously in this specification. Security Portion 1104 also typically comprises a processor, chip, logic device, or smart device 1141 and an input buffer 1140, which buffers outgoing and incoming messages/data that are sent to and received from Application Control Device 1102.
Another aspect of this invention is a rolling transaction code generator 1120 that is associated with (e.g., contained within) Application Control Device 1102. As stated previously, this rolling transaction code is analogous to the one-time Transaction Number previously described in this specification. The rolling transaction code typically comprises the current date, the current time, a unique identification of the Remote Device 1101 being controlled, and an optional field, which may include relevant comments, subject matter information, etc. This rolling transaction code follows the principle of de-identification that permeates all the embodiments described in this specification, which means that no user account numbers are used. This greatly contributes to the overall security of the system. In lieu of a user account number, the rolling transaction code also comprises a unique occurrence number, which uniquely identifies the particular transaction (occurrence), i.e., a number that identifies which particular occurrence of control or measurement is being exercised. This occurrence number (which can contain elements other than numbers, such as letters, punctuation marks, etc.) is changed for each such occurrence. For reasons of security, the occurrence number should not be simply incremented for each occurrence, because that would make it easier for nefarious entities to hack the system.
In operation, processor, chip, logic device, or smart device 1141 checks the rolling transaction code against pre-stored information contained in a random access memory 1143 associated with processor, chip, logic device, or smart device 1141, and verifies the validity of the rolling transaction code before allowing the transaction to proceed. As another security feature, processor, chip, logic device, or smart device 1141 also checks that each control message sent from Application Control Device 1102 to Security Portion 1104 contains the correct security portion identifier 1142 for that particular Security Portion 1104. Of course, it is important to maintain the confidentiality of security portion identifier 1142.
Processor, chip, logic device, or smart device 1141 also checks to see that there is a valid connection from processor, chip, logic device, or smart device 1131 before processor, chip, logic device, or smart device 1141 forwards commands to processor, chip, logic device, or smart device 1131. This guards against the first security issue identified above, namely, the eventuality that Remote Device 1101 has become disabled.
As another means to improve the security of the system, a User Activation Module 1108, separate and apart from Application Control Device 102, can be associated with (either proximally or distally) Security Portion 1104. In these embodiments, User Activation Module 1108 accepts one or more of a set of pre-established identification/verification inputs before processor, chip, logic device, or smart device 1141, which is coupled to User Activation Module 1108, is allowed to perform any of its designated tasks. Such identification/verification inputs can include, but are not limited to, biometric inputs (such as fingerprints and retinal scans), alphanumeric inputs such as a PIN (Personal Identification Number), and/or physical keys.
SPARCPrivate and SPARCeiverThe principles described herein can be further extended to a system which we here characterize as SPARCPrivate. With reference to
The first major security threat is that outgoing (from the point of view of Smart Device 1202) messages could be read (intercepted) by third parties for purposes of invading the privacy of the sending Smart Device 1202. This nefarious activity can include capturing the identification of the Smart Device 1202 and/or spying on the actions of the Smart Device 1202.
The second major security threat is that incoming (into Smart Device 1202) messages could contain one or more of a wide variety of viruses, fraudulent software applications, and/or other types of malware. All of this malware is designed to injure the message recipient 1202 and/or to steal the identification and/or personal information of the recipient 1202.
The present invention addresses these security threats in the following manner. A SPARCPrivate Control Center 1201 is coupled to the Smart Device 1202, and is adapted to receive from the Smart Device 1202 a unique security device identification that the Smart Device 1202 has received from its associated SPARC Security Device 1204 (e.g., the previously described SSD 104). Control Center 1201 also receives from Smart Device 102 a smart device identifier and instructions for initiating a transaction, such as a request to purchase a package from a merchant 1205. The SPARCPrivate Control Center 1201, which can be functionally identical to the Application Controlling Institution 101 described previously in this specification, checks the validity of the smart device identifier, and replaces the smart device identifier with a unique security device identification. This follows the principle of de-identification described previously herein, and hinders the ability of nefarious entities to spy on the actions of Smart Device 1202.
The SPARCPrivate Control Center 1201 includes the security device identification and the instructions in an outgoing message 1207, which Control Center 1201 then sends to the merchant 1205 over the Internet 1203.
To further enhance security, SPARCPrivate Control Center 1201 in some embodiments adds two physical return addresses to the message 1207 before sending the message 1207 to the merchant 1205. The first physical address is that of the entity associated with the Smart Device 1202, i.e., the address where the user of the Smart Device 1202 wishes the package from the merchant 1205 to be sent. The second physical address is that of an intermediary fulfillment center 1206. In these embodiments, the merchant 1205 sends the package that has been ordered to the physical address of the fulfillment center 1206, along with the first physical address. The fulfillment center 1206, in turn, sends the package to the first physical address by any available delivery means, such as USPS, Federal Express, UPS, DHL, etc.
When implemented as a business, the user of the Smart Device 1202 wishing to use this SPARCPrivate service can be asked to pay a monthly fee and/or a fee per transaction and/or any additional freight charges necessitated by the package being sent via the fulfillment center 1206 (rather than being sent directly from the merchant 1205).
Other embodiments include another feature to increase security even further: the association of a security module that we refer to as SPARCeiver 1208 with the input side of the Smart Device 1202. In these embodiments, incoming messages that are sent to the Smart Device 1202 from the Internet 1203 must first pass through the SPARCeiver 1208, which performs a real-time malware scan to detect and remove from each message as many viruses, fraudulent software applications, and other types of malware before allowing the message to be forwarded to the Smart Device 1202. Optionally, SPARCeiver 1208 also replaces a security device identification that may be associated with the incoming message with the smart device identifier, which enables the Smart Device 1202 to check the smart device identifier in the incoming message with what the Smart Device 1202 knows to be its true smart device identifier, before Smart Device 102 accepts the incoming message.
SPARCeiver 1208 can be a stand-alone interface to the Internet 1203, and can be used in conjunction with any Smart Device 1202. Alternatively, SPARCeiver 1208 can be built into Smart Device 1202 and act as Device 102's interface to the Internet 1203. Each SPARCeiver 1208 has a companion SPARC Security Device 1204.
SPARCeiver 1208 typically has a physical size smaller than the size of a smart phone. SPARCeiver 1208 typically contains a communications buffer 1211, which receives and buffers incoming messages received from the Internet 1203, and formats and buffers outgoing messages prior to their being sent over the Internet 1203. Coupled to the communications buffer 1211 is a processor, chip, logic device, or smart device 1212, which contains programmable logic and arithmetic, and performs all of the functions that one normally attributes to a microprocessor. Processor, chip, logic device, or smart device 1212 is coupled to Smart Device 1202, and is also coupled to three memories (storage areas): a memory module 1213 that stores software applications that are used by the processor, chip, logic device, or smart device 1212, a memory module 1214 containing a set of valid security device identifications, and a memory module 1215 that serves as a temporary storage for messages that are being worked on by processor, chip, logic device, or smart device 1212. The companion SPARC Security Device 1204 is coupled to processor, chip, logic device, or smart device 1212 (e.g., indirectly via buffer 1211) via memory 1214. The coupling means is typically an NFC interface 1216. The three memories, 1213, 1214, and 1215, can be flash drives each having a capacity of about 3 Gigabytes.
The communications buffer 1211 typically has a storage capacity sufficient to buffer between 10 and 100 messages, based upon the model of SPARCeiver 1208 that is selected by the customer. The processing speed of processor, chip, logic device, or smart device 1212 can also vary based upon the model selected by the customer, and is typically roughly proportional to the size of communications buffer 1211.
In operation, SPARCeiver 1208 buffers all incoming messages arriving from the Internet 1203 using communications buffer 1211, and then processor, chip, logic device, or smart device 1212 scans each incoming message for malware. Processor, chip, logic device, or smart device 1212 does this by invoking anti-malware software that is stored in memory 1213. If the incoming message passes the malware test, processor, chip, logic device, or smart device 1212 temporarily stores the message in memory 1215. If the message fails the malware test, processor, chip, logic device, or smart device 1212 obliterates the message containing the malware.
Some, but not all, incoming messages contain a security device identification. The presence of a security device identification in the incoming message provides an additional level of security, compared to those incoming messages that do not contain a security device identification.
For those incoming messages that do contain a security device identification, processor, chip, logic device, or smart device 1212 checks the validity of the security device identification by means of consulting the memory 1214. If the security device identification is valid, processor, chip, logic device, or smart device 1212 moves the incoming message from temporary storage 1215 into Smart Device 1202, which processes the message. If the security device identification in the incoming message is invalid, processor, chip, logic device, or smart device 1212 obliterates the message.
For each outgoing message that is sent from Smart Device 1202 over the Internet 1203, the message is first sent to SPARCeiver 1208. Processor, chip, logic device, or smart device 1212 temporarily stores the message in memory 1215. Processor, chip, logic device, or smart device 1212 then invokes the anti-malware scanning software application from memory 1213 to scan the message for malware. If malware is present in the message, processor, chip, logic device, or smart device 1212 obliterates the message. If the message passes the malware test, processor, chip, logic device, or smart device 1212 affixes a valid security device identification to the message. Processor, chip, logic device, or smart device 1212 obtains this security device identification from memory 1214. Processor, chip, logic device, or smart device 1212 then sends the message to communications buffer 1211, which formats the message and sends it over the Internet 1203.
SPARChealth Security DeviceIn a further extension of the principles of the present invention as described previously herein, the SPARC Security Device 104 can be adapted to perform as a SPARChealth Security Device 1304, as illustrated in
SPARChealth Security Device 1304 typically comprises a processor, chip, logic device, or smart device 1314 (analogous to processor 114 previously described), and, coupled to the processor, chip, logic device, or smart device 1314, a communications module 1318 (analogous to communications module 118) and a set of memory modules 1311, 1312, 1313, 1315, and 1319.
Processor, chip, logic device, or smart device 1314 contains programmable logic and arithmetic, as one would expect in a typical microprocessor.
One or more of memories 1311, 1312, 1313, 1315, 1319 can comprise a flash drive memory, e.g., one having about 3 Gigabytes of data capacity and the ability to connect to SPARChealth Security Device 1304 via a USB port associated with communications module 1318.
Memory 1311 is a rolling transaction count register, which stores the current transaction count for the particular health transaction that is being worked on by the SPARChealth Security Device 1304. Processor 1314 uses an algorithm to update the rolling transaction count for each current transaction, and stores this transaction count in register 1311. This updating is performed in the manner previously described in this specification, e.g., it is not wise from a security point of view to simply increment the transaction count by one for each subsequent transaction.
Memory 1312 stores a SPARChealth security device identification, which is unique for each SPARChealth Security Device 1304.
Memory 1313 stores emergency health information pertaining to the user of SPARChealth Security Device 1304. This emergency health information memory 1313, which can be thought of as a digital emergency card, typically stores emergency contact information for the user, the user's name, birth date, medication information, weight, eye color, blood type, organ donor status, physical address, and similar information.
Memory 1319 stores real time health information for the user. This information can be provided to SPARChealth Security Device 1304 via communications module 1318. This information can be provided by the user via user input module 1316, by one or more non-confidential health information providers (e.g., a provider who posted the information on a Web page) via module 1328, and/or by inputs from health monitor inputs module 1317, which serves as a vehicle for conveying to SSD 1304 measurements obtained by one or more health monitors, such as a heart monitor affixed to the user.
The real time health data memory 1319 stores information pertaining to, e.g., blood work, heart rate, hydration, blood pressure, typical physical activity level, nutrition, blood sugar level, amount of sleep that the user has enjoyed recently, respiratory rate, oxygen saturation, and the user's weight.
Memory 1315 serves as a place for processor, chip, logic device, or smart device 1314 to store historical information pertaining to transactions, such as records that are needed to comply with HIPAA legislation.
SPARChealth Security Device 1304 communicates with an accompanying Smart Device 1302 via a connection 1306, which is typically an NFC wireless connection. Smart Device 1302 is adapted to initiate health transactions originated by the user of SD 1302 and SSD 1304. These health transactions are initiated in the same manner as transactions that have been previously described in this specification. Confidential health transactions are communicated by Smart Device 1302 to a Health Application Controlling Institution (HACI) 1301, which can be structurally identical to the Application Controlling Institution 101 that has been previously described in this specification. When Smart Device 1302 communicates a transaction to HACI 1301, Smart Device 1302 forwards to HACI 1301 the unique SPARC security device identification 1312 (e.g., the previously described SSD Unit Identifier) and the rolling transaction count, but not any account information, credit card information, or other information that would identify the true user. This communication thus adheres to the principle of de-identification which has been previously discussed in this specification.
HACI 1301 processes the confidential health transaction by means of confidentially communicating with one or more health service providers 1320 and/or one or more health insurance providers 1321.
Similarly, when information is sent back from HACI 1301 to Smart Device 1302, the unique SPARChealth security device identification 1312 and the current transaction count are included with the return message, but not the user's account number, credit card information, or other information that could expose the true identity of the user.
Security for the Internet of ThingsWith reference to
Peer-to-peer communications between and among non-human devices is becoming increasingly prevalent in modern society. For example, a food refrigerator may communicate with a supermarket to re-order food to restock itself. As another example, a household cooling fan may communicate with a room thermometer to determine the current temperature and to make subsequent decisions regarding turning on, turning off, fan speed, etc. As another example, a 3D printer may communicate with a database to determine whether added devices are required to refill an inventory of available devices in a hardware store.
These and other peer-to-peer communications are regrettably susceptible to attacks emanating from a plethora of nefarious people and shadowy organizations. For example, fraudulent software applications can be inserted into the communications paths in attempts to steal industrial secrets. Another problem is that the communications can be overheard, and then used to usurp control of various pieces of equipment and cause malfunctioning thereof. As another example, viruses and other malware may be introduced into the communications system to interrupt routine communications between or among smart devices 1401, 1402, 1403. These attacks have been inhibiting the growth of the Internet Of Things and other Networks Of Things, at great cost to society.
Each bidirectional smart device 1401, 1402, 1403 is coupled to the network 1450 via an associated bidirectional intelligent chip, logic device, or smart device 1411, 1421, 1431.
When a message 1460 is being sent from first smart device 1401 to second smart device 1402, intelligent chip, logic device, or smart device 1411 associated with first smart device 1401 appends a message identifier 1417 to the outgoing message 1460. The identifier 1417 comprises a fixed portion identifying the device 1401 type and uniquely identifying the device 1401. This unique portion is stored in memories 1415, 1416 within chip, logic device, or smart device 1411. Memory 1415 stores a digitized representation of the type of the device 1401, and memory 1416 stores a unique digitized identification of the specific device 1401. Message ID 1417 also comprises a variable portion, which, together with the fixed portion, provides realtime security without the use of encryption, PINs, or passwords.
Each intelligent chip, logic device, or smart device 1431, such as the illustrated intelligent chip, logic device, or smart device 1421 associated with second smart device 1401, comprises all the items shown in
Message 1460 contains the addresses of the one or more smart devices 1402 that smart device 1401 has designated to receive the message 1460. These addresses are in a format usable by the particular network 1450. For example, when network 1450 is the Internet, these addresses may be the Internet Protocol (IP) addresses of the receiving smart devices 1402. The message package that is sent by intelligent chip, logic device, or smart device 1411 over communications link 1441 to network 1450, and then over communications link 1442 to intelligent chip, logic device, or smart device 1421, comprises the substantive portion of the message 1460 as originated by the sending smart device 1401, the address of one or more receiving smart devices 1402, and the message identifier 1417.
Communications links 1441 and 1442 can be any wired or wireless communications links.
Second smart device 1402, in addition to performing the functions of a receiving smart device, is also built to perform the functions of a sending smart device, as is true for all smart devices 1403. This bidirectionality feature is useful, inter alia, when the sending smart device 1401 desires or requires feedback to a message 1460 that it sends. Each bidirectional smart device 1403 operates in conjunction with its associated bidirectional intelligent chip, logic device, or smart device 1431 that has been built and programmed to perform the functions of both a sending and receiving.
In one embodiment, message ID 1417 comprises 40 digits and adheres to the ISO Track 2 format. This is a very useful embodiment, in that many industry protocols, such as magnetic stripes in debit and credit cards, and smart phones, use this format.
As illustrated in
In some embodiments, the time having a random starting point, as output by clock 1414, is used by processor, chip, logic device, or smart device 1413 as the variable portion of the message identifier 1417. For security purposes, this random starting time is a closely held secret, and is fed by secure means from the human user or from one of the smart devices 1403 to all the clocks 1414, 1424 in the network.
The random start time may be changed from time to time for greater security. The more frequently the random start time is changed, the greater the security. As just one example, the random start time may be changed daily.
In some embodiments, the fixed portion of message identifier 1417 is a composite of the digitized version of the smart device 1401 type from memory 1415, and the smart device unique identifier from memory 1416. The combined variable and fixed portions of message ID 1417 are combined with the actual substantive message 1460 (including addresses), and sent to a transmitter/receiver 1418 within chip, logic device, or smart device 1411, where the message package is put in a suitable form for transmission over link 1441. Transmitter/receiver 1418 may comprise a modem, codec, or other device that is specifically tailored for that particular network 1450 and its communications protocols.
When digitizing the time received from clock 1414, processor, chip, logic device, or smart device 1413 assigns the time into a digitized interval bucket. The time interval can be preselected by the user of chip, logic device, or smart device 1411.
Bidirectional intelligent chip, logic device, or smart device 1421 receives the message package via transmitter/receiver 1428. Like transmitter/receiver 1418, transmitter/receiver 1428 is selected to be compatible with the communications protocols of network 1450 and the associated timing and formatting requirements of chip, logic device, or smart device 1421, as would be well known to one of ordinary skill in the art.
The message package is then routed to processor, chip, logic device, or smart device 1423 within chip, logic device, or smart device 1421 for purposes of verifying that the message 1460 is legitimate and thus appropriate to be sent on to smart device 1402.
The verification process performed by processor, chip, logic device, or smart device 1423 comprises a verification of the variable portion of message identifier 1417, and an independent verification of the fixed portion of message identifier 1417.
The verification of the variable portion of identifier 1417 comprises processor, chip, logic device, or smart device 1423 obtaining the time having the secret random starting point (and the date where the date is used) from clock 1424. Processor, chip, logic device, or smart device 1423 then determines whether this time obtained from clock 1424 is within a preselected acceptable amount of time from the time that was appended by chip, logic device, or smart device 1411 as part of identifier 1417. This preselected acceptable time lag can be set in chip, logic device, or smart device 1421 by a user of the system. This check of the time guards against replay attacks, i.e., when a nefarious entity intercepts the message 1460, perhaps altering the message, then resends it at a later time to an unsuspecting smart device 1403. The reason for using a time having a random starting point, rather than simply using the current time, is that this makes it much harder for a nefarious entity to hack into the system. This is because the nefarious entity presumably knows the current date and time, but will have great difficulty in determining the secret random starting time.
The verification of the fixed portion of identifier 1417 typically comprises processor, chip, logic device, or smart device 1423 consulting two whitelists within chip, logic device, or smart device 1421. The first whitelist 1425 is a list of acceptable types of sending smart devices 1401. The second whitelist 1426 is a list of acceptable unique identifications of specific sending smart devices 1401. In an alternate embodiment, the two whitelists 1425, 1426 can be combined into a single whitelist.
When and only when both the variable and the fixed verification steps are successfully completed, processor, chip, logic device, or smart device 1423 sends the message 1460 to the one or more smart devices 1402 that have been designated to receive message 1460. Message identifier 1417 may optionally be appended to message 1460 by processor, chip, logic device, or smart device 1423, to give each receiving smart device 1402 an indication of when the message 1460 was packaged by chip, logic device, or smart device 1411, as well as the type and unique identification of the particular smart device 1401 that originated the message 1460.
The message 1460 is sent by chip, logic device, or smart device 1421 to smart device 1402 via optional buffer 1422, which is used when it is desired or required to put the format and/or the timing of the message 1460 into compatibility with the protocols used by smart device 1402.
When processor, chip, logic device, or smart device 1423 is not able to verify the bona fides of message 1460, processor, chip, logic device, or smart device 1423 typically destroys the message 1460, because such an unverified message 1460 may cause damage to system resources if it is not eliminated.
In certain embodiments, when smart device 1402 receives a valid message 1460, smart device 1402 sends an acknowledgement message back to smart device 1401 through chip, logic device, or smart device 1421, network 1450, and chip, logic device, or smart device 1411.
In certain embodiments, all the clocks 1414, 1424 are synchronized periodically, e.g., daily, to maintain integrity of the time checks described above, by means of synchronization signals sent from the human user or from the designated smart device 1403.
If smart device 1402 wishes to send a message back to smart device 1401, the above-described process is reversed. In this case, chip, logic device, or smart device 1421 performs the functions previously described with respect to chip, logic device, or smart device 1411; and chip, logic device, or smart device 1411 performs the functions previously described with respect to chip, logic device, or smart device 1421.
