This application is a continuation of U.S. patent application Ser. No. 12/619,948 filed on Nov. 17, 2009, entitled “MESSAGE SERVICE INDICATION SYSTEM AND METHOD,” which is a continuation of U.S. patent application Ser. No. 11/066,406 filed on Feb. 25, 2005, now U.S. Pat. No. 7,627,757, entitled “MESSAGE SERVICE INDICATION SYSTEM AND METHOD,” which claims the benefit of and priority to U.S. Provisional Application No. 60/566,772, filed on Apr. 30, 2004, entitled “MESSAGE SERVICE INDICATION SYSTEM AND METHOD,” all of which are hereby incorporated by reference in their entirety.
BACKGROUND1. Technical Field
The present invention relates generally to the field of communications, and in particular to indicating message services on computing devices.
2. Description of the Related Art
Some government agencies have multiple networks, each with different degrees of security. Messages received in a top-security network are typically more important than messages received in a non-secret network and should be treated by the receiver of the message differently.
Government officials that have accounts set up in more than one network would like to receive all of their e-mail messages on one mobile device, not multiple mobile devices (i.e., one for each network they are connected to). For this reason, they would like to easily and effectively be able to determine, among other things, from which network or e-mail server a message came. With such information, they are more likely to treat the message properly from a security aspect.
One approach could include showing in the first field when viewing the message which service the message is from. However, this field may not be visible when the user first opens the message, and the user would have to scroll to the top of the message, through all of the recipients, to view service source information.
SUMMARYIn accordance with the teachings disclosed herein, systems and methods are provided for displaying e-mail messages. As an example of a system and method, messages are displayed to a user wherein a security related level of the message is determined. A visual indication for display to a device user is generated based upon the determined security-related level. Such visual indication is configured to be visible through a majority of text associated with the message.
As another example, a data processing device can be configured for handling messages with different levels of security. A receiver can be configured to be operable to receive a message via a network, and security logic instructions can be configured to be operable to examine an attribute of the message and to determine a security-related level associated with the message. User interface logic instructions can generate a visual indication for display to a device user responsive to the determined security-related level associated with the message. The generated visual indication can be configured to be visible during scrolling through all or a majority of the message text.
As will be appreciated, the disclosed systems and methods are capable of different embodiments, and their details are capable of modifications in various respects. Accordingly, the drawings and description set forth below are to be regarded as illustrative in nature and not restrictive.
An e-mail sender system 10 may, for example, be connected to an ISP (Internet Service Provider) on which a user of the system 10 has an account, located within a company, possibly connected to a local area network (LAN), and connected to the Internet 20, or connected to the Internet 20 through a large ASP (application service provider) such as America Online (AOL). Those skilled in the art will appreciate that the systems shown in
The message server 40 may be implemented, for example, on a network computer within the firewall of a corporation, a computer within an ISP or ASP system or the like, and acts as the main interface for e-mail exchange over the Internet 20. Although other messaging systems might not require a message server system 40, a mobile device 100 configured for receiving and possibly sending e-mail will normally be associated with an account on a message server. Perhaps the two most common message servers are Microsoft Exchange™ and Lotus Domino™. These products are often used in conjunction with Internet mail routers that route and deliver mail. These intermediate components are not shown in
The wireless gateway 85 and infrastructure 90 provide a link between the Internet 20 and wireless network 105. The wireless infrastructure 90 determines the most likely network for locating a given user and tracks the user as they roam between countries or networks. A message is then delivered to the mobile device 100 via wireless transmission, typically at a radio frequency (RF), from a base station in the wireless network 105 to the mobile device 100. The particular network 105 may be virtually any wireless network over which messages may be exchanged with a mobile communication device.
As shown in
Regardless of the specific mechanism controlling the forwarding of messages to the mobile device 100, the message 15, or possibly a translated or reformatted version thereof, is sent to the wireless gateway 85. The wireless infrastructure 90 includes a series of connections to wireless network 105. These connections could be Integrated Services Digital Network (ISDN), Frame Relay or T1 connections using the TCP/IP protocol used throughout the Internet. As used herein, the term “wireless network” is intended to include three different types of networks, those being (1) data-centric wireless networks, (2) voice-centric wireless networks and (3) dual-mode networks that can support both voice and data communications over the same physical base stations. Combined dual-mode networks include, but are not limited to, (1) Code Division Multiple Access (CDMA) networks, (2) the Groupe Special Mobile or the Global System for Mobile Communications (GSM) and the General Packet Radio Service (GPRS) networks, and (3) future third-generation (3G) networks like Enhanced Data-rates for Global Evolution (EDGE) and Universal Mobile Telecommunications Systems (UMTS). Some older examples of data-centric network include the Mobitex™ Radio Network and the DataTAC™ Radio Network. Examples of older voice-centric data networks include Personal Communication Systems (PCS) networks like GSM, and TDMA systems.
The central host system 30 will typically be a corporate office or other LAN, but may instead be a home office computer or some other private system where mail messages are being exchanged. Within the host system 30 is the message server 40, running on some computer within the firewall of the host system, that acts as the main interface for the host system to exchange e-mail with the Internet 20. In the system of
As shown in
In the automatic redirection system of
With reference back to the port 50 and cradle 65 connectivity to the mobile device 100, this connection path offers many advantages for enabling one-time data exchange of large items. For those skilled in the art of personal digital assistants (PDAs) and synchronization, the most common data exchanged over this link is Personal Information Management (PIM) data 55. When exchanged for the first time this data tends to be large in quantity, bulky in nature and requires a large bandwidth to get loaded onto the mobile device 100 where it can be used on the road. This serial link may also be used for other purposes, including setting up a private security key 111 such as an S/MIME or PGP specific private key, the Certificate (Cert) of the user and their Certificate Revocation Lists (CRLs) 60. The private key is preferably exchanged so that the desktop 35 and mobile device 100 share one personality and one method for accessing all mail. The Cert and CRLs are normally exchanged over such a link because they represent a large amount of the data that is required by the device for S/MIME, PGP and other public key security methods.
For example,
As another example of visual indicators,
A visual indicator (e.g., background color, font size, etc.) could be applied to only the body of the displayed message, or could be applied to other parts of the message as well, such as the message “TO” and/or “FROM” and/or “SUBJECT” header lines. The latter aspect effectively prevents an attacker from confusing the recipient of a message as to the message's true sensitivity level or source, if the attacker tries to create a message body whose visual characteristics match or substantially match the visual characteristics utilized by the mobile device to denote message sensitivity, source, etc.
Decision step 408 examines whether a visual indication is to be displayed to a user based upon the one or more determined security-related aspects associated with the received message. If a visual indication is not to be generated as determined at decision step 408, then the message at step 410 is displayed normally (e.g., the background color is not altered) before the operational scenario ends at end block 414. However, if a visual indication is to be generated, step 412 changes one or more visual characteristics of the user screen when the contents of the message are viewed. It should be understood that similar to the other processing flows described herein, the steps and the order of the steps in the flowchart described herein may be altered, modified and/or augmented and still achieve the desired outcome. For example, it should be understood that other visual indicators can be provided to a user, including a mobile device 100 notifying the user whether the message is insecure instead of secure.
The IT administrator 500 can specify visual indicator settings 520 to one or more devices. The settings 520 may be provided to the mobile device 100 over a network (or other data connection mechanism) in order to update the data store on the mobile device 100. The mobile device 100 can be pre-programmed with the settings and can be updated by the IT administrator 500 or can have the initial settings provided on the mobile device 100 by the IT administrator 500.
This provides, among other things, companies with the capability to customize visual indicator settings to suit their needs. Also, an IT administrator 500 can provide the same settings to all mobile devices of the company or organization, thereby ensuring that company mobile devices adhere to a consistent IT policy.
An IT policy can be enforced upon mobile devices in many ways, such as through the approaches described in the following commonly assigned United States patent application which is hereby incorporated by reference: “System And Method Of Owner Control Of Electronic Devices” (Ser. No. 10/732,132 filed on Dec. 10, 2003). This document illustrates how a user of the mobile device can be prevented from altering or erasing owner control information (e.g., visual indicator settings 520) specified by an IT administrator 500.
At step 602 of
Decision step 608 examines whether a visual indication is to be displayed to a user based upon the determined security-related aspects associated with the received message. If a visual indication is not to be generated as determined at decision step 608 then the message is displayed normally at step 610 before the operational scenario ends at end block 614. However, if a visual indication is to be generated, step 612 changes one or more visual characteristics of the user screen when the contents of the message are viewed. The operational scenario ends at end block 614.
The systems and methods disclosed herein are presented only by way of example and are not meant to limit the scope of the invention. Other variations of the systems and methods described above will be apparent to those skilled in the art and as such are considered to be within the scope of the invention. For example, a visual indicator can utilize many different types of visual characteristics for displaying the message. As shown in
Still further, multiple visual indicators can be used on the same mobile device display, such as a first visual indication being used to designate a first feature (e.g., message source) and a second visual indication to designate a second feature (e.g., message sensitivity level) when the message is displayed to a user.
As another example, the systems and methods disclosed herein may be used with many different computers and devices, such as a personal digital assistant (PDA) or a wireless mobile communications device that is shown in
The mobile device 100 is preferably a two-way communication device having voice and data communication capabilities. Thus, for example, the mobile device 100 may communicate over a voice network, such as any of the analog or digital cellular networks, and may also communicate over a data network. The voice and data networks are depicted in
The transceiver 811 is used to communicate with the network 819, and includes the receiver 812, the transmitter 814, the one or more local oscillators 813 and the DSP 820. The DSP 820 is used to send and receive signals to and from the transceivers 816 and 818, and also provides control information to the receiver 812 and the transmitter 814. If the voice and data communications occur at a single frequency, or closely-spaced sets of frequencies, then a single local oscillator 813 may be used in conjunction with the receiver 812 and the transmitter 814. Alternatively, if different frequencies are utilized for voice communications versus data communications for example, then a plurality of local oscillators 813 can be used to generate a plurality of frequencies corresponding to the voice and data networks 819. Information, which includes both voice and data information, is communicated to and from the transceiver 811 via a link between the DSP 820 and the microprocessor 838.
The detailed design of the transceiver 811, such as frequency band, component selection, power level, etc., will be dependent upon the communication network 819 in which the mobile device 100 is intended to operate. For example, a mobile device 100 intended to operate in a North American market may include a transceiver 811 designed to operate with any of a variety of voice communication networks, such as the Mobitex or DataTAC mobile data communication networks, AMPS, TDMA, CDMA, PCS, etc., whereas a mobile device 100 intended for use in Europe may be configured to operate with the GPRS data communication network and the GSM voice communication network. Other types of data and voice networks, both separate and integrated, may also be utilized with a mobile device 100.
Depending upon the type of network or networks 819, the access requirements for the mobile device 100 may also vary. For example, in the Mobitex and DataTAC data networks, mobile devices are registered on the network using a unique identification number associated with each mobile device. In GPRS data networks, however, network access is associated with a subscriber or user of a mobile device. A GPRS device typically requires a subscriber identity module (“SIM”), which is required in order to operate a mobile device on a GPRS network. Local or non-network communication functions (if any) may be operable, without the SIM device, but a mobile device will be unable to carry out any functions involving communications over the data network 819, other than any legally required operations, such as ‘911’ emergency calling.
After any required network registration or activation procedures have been completed, the mobile device 100 may the send and receive communication signals, including both voice and data signals, over the networks 819. Signals received by the antenna 816 from the communication network 819 are routed to the receiver 812, which provides for signal amplification, frequency down conversion, filtering, channel selection, etc., and may also provide analog to digital conversion. Analog to digital conversion of the received signal allows more complex communication functions, such as digital demodulation and decoding to be performed using the DSP 820. In a similar manner, signals to be transmitted to the network 819 are processed, including modulation and encoding, for example, by the DSP 820 and are then provided to the transmitter 814 for digital to analog conversion, frequency up conversion, filtering, amplification and transmission to the communication network 819 via the antenna 818.
In addition to processing the communication signals, the DSP 820 also provides for transceiver control. For example, the gain levels applied to communication signals in the receiver 812 and the transmitter 814 may be adaptively controlled through automatic gain control algorithms implemented in the DSP 820. Other transceiver control algorithms could also be implemented in the DSP 820 in order to provide more sophisticated control of the transceiver 811.
The microprocessor 838 preferably manages and controls the overall operation of the mobile device 100. Many types of microprocessors or microcontrollers could be used here, or, alternatively, a single DSP 820 could be used to carry out the functions of the microprocessor 838. Low-level communication functions, including at least data and voice communications, are performed through the DSP 820 in the transceiver 811. Other, high-level communication applications, such as a voice communication application 824A, and a data communication application 824B may be stored in the non-volatile memory 824 for execution by the microprocessor 838. For example, the voice communication module 824A may provide a high-level user interface operable to transmit and receive voice calls between the mobile device 100 and a plurality of other voice or dual-mode devices via the network 819. Similarly, the data communication module 824B may provide a high-level user interface operable for sending and receiving data, such as e-mail messages, files, organizer information, short text messages, etc., between the mobile device 100 and a plurality of other data devices via the networks 819.
The microprocessor 838 also interacts with other device subsystems, such as the display 822, the RAM 826, the auxiliary input/output (I/O) subsystems 828, the serial port 830, the keyboard 832, the speaker 834, the microphone 836, the short-range communications subsystem 840 and any other device subsystems generally designated as 842.
Some of the subsystems shown in
Operating system software used by the microprocessor 838 is preferably stored in a persistent store such as non-volatile memory 824. The non-volatile memory 824 may be implemented, for example, as a Flash memory component, or as battery backed-up RAM. In addition to the operating system, which controls low-level functions of the mobile device 810, the non-volatile memory 824 includes a plurality of software modules 824A-824N that can be executed by the microprocessor 838 (and/or the DSP 820), including a voice communication module 824A, a data communication module 824B, and a plurality of other operational modules 824N for carrying out a plurality of other functions. These modules are executed by the microprocessor 838 and provide a high-level interface between a user and the mobile device 100. This interface typically includes a graphical component provided through the display 822, and an input/output component provided through the auxiliary I/O 828, keyboard 832, speaker 834, and microphone 836. The operating system, specific device applications or modules, or parts thereof, may be temporarily loaded into a volatile store, such as RAM 826 for faster operation. Moreover, received communication signals may also be temporarily stored to RAM 826, before permanently writing them to a file system located in a persistent store such as the Flash memory 824.
An exemplary application module 824N that may be loaded onto the mobile device 100 is a personal information manager (PIM) application providing PDA functionality, such as calendar events, appointments, and task items. This module 824N may also interact with the voice communication module 824A for managing phone calls, voice mails, etc., and may also interact with the data communication module for managing e-mail communications and other data transmissions. Alternatively, all of the functionality of the voice communication module 824A and the data communication module 824B may be integrated into the PIM module.
The non-volatile memory 824 preferably also provides a file system to facilitate storage of PIM data items on the device. The PIM application preferably includes the ability to send and receive data items, either by itself, or in conjunction with the voice and data communication modules 824A, 824B, via the wireless networks 819. The PIM data items are preferably seamlessly integrated, synchronized and updated, via the wireless networks 819, with a corresponding set of data items stored or associated with a host computer system, thereby creating a mirrored system for data items associated with a particular user.
Context objects representing at least partially decoded data items, as well as fully decoded data items, are preferably stored on the mobile device 100 in a volatile and non-persistent store such as the RAM 826. Such information may instead be stored in the non-volatile memory 824, for example, when storage intervals are relatively short, such that the information is removed from memory soon after it is stored. However, storage of this information in the RAM 826 or another volatile and non-persistent store is preferred, in order to ensure that the information is erased from memory when the mobile device 100 loses power. This prevents an unauthorized party from obtaining any stored decoded or partially decoded information by removing a memory chip from the mobile device 100, for example.
The mobile device 100 may be manually synchronized with a host system by placing the device 100 in an interface cradle, which couples the serial port 830 of the mobile device 100 to the serial port of a computer system or device. The serial port 830 may also be used to enable a user to set preferences through an external device or software application, or to download other application modules 824N for installation. This wired download path may be used to load an encryption key onto the device, which is a more secure method than exchanging encryption information via the wireless network 819. Interfaces for other wired download paths may be provided in the mobile device 100, in addition to or instead of the serial port 830. For example, a USB port would provide an interface to a similarly equipped personal computer.
Additional application modules 824N may be loaded onto the mobile device 100 through the networks 819, through an auxiliary I/O subsystem 828, through the serial port 830, through the short-range communications subsystem 840, or through any other suitable subsystem 842, and installed by a user in the non-volatile memory 824 or RAM 826. Such flexibility in application installation increases the functionality of the mobile device 100 and may provide enhanced on-device functions, communication-related functions, or both. For example, secure communication applications may enable electronic commerce functions and other such financial transactions to be performed using the mobile device 100.
When the mobile device 100 is operating in a data communication mode, a received signal, such as a text message or a web page download, is processed by the transceiver module 811 and provided to the microprocessor 838, which preferably further processes the received signal in multiple stages as described above, for eventual output to the display 822, or, alternatively, to an auxiliary I/O device 828. A user of mobile device 100 may also compose data items, such as e-mail messages, using the keyboard 832, which is preferably a complete alphanumeric keyboard laid out in the QWERTY style, although other styles of complete alphanumeric keyboards such as the known DVORAK style may also be used. User input to the mobile device 100 is further enhanced with a plurality of auxiliary I/O devices 828, which may include a thumbwheel input device, a touchpad, a variety of switches, a rocker input switch, etc. The composed data items input by the user may then be transmitted over the communication networks 819 via the transceiver module 811.
When the mobile device 100 is operating in a voice communication mode, the overall operation of the mobile device is substantially similar to the data mode, except that received signals are preferably be output to the speaker 834 and voice signals for transmission are generated by a microphone 836. Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on the mobile device 100. Although voice or audio signal output is preferably accomplished primarily through the speaker 834, the display 822 may also be used to provide an indication of the identity of a calling party, the duration of a voice call, or other voice call related information. For example, the microprocessor 838, in conjunction with the voice communication module and the operating system software, may detect the caller identification information of an incoming voice call and display it on the display 822.
A short-range communications subsystem 840 is also included in the mobile device 100. The subsystem 840 may include an infrared device and associated circuits and components, or a short-range RF communication module such as a Bluetooth™ module or an 802.11 module, for example, to provide for communication with similarly-enabled systems and devices. Those skilled in the art will appreciate that “Bluetooth” and “802.11” refer to sets of specifications, available from the Institute of Electrical and Electronics Engineers, relating to wireless personal area networks and wireless local area networks, respectively.
