Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The invention relates to the exchange of data securely, in particular to the exchange of data using a digital cellular wireless communications network.

2. Description of the Related Art

An increasing number of people are exchanging sensitive data using telecommunication devices over digital cellular wireless communication networks. It is not safe to store this information on the telecommunications device its self, because it can be stolen. Likewise it is inconvenient for the user to always enter data into their telecommunications device when completing a transaction or using a secure website. These devices typically have touch screens, and it can be time consuming to enter the same data for similar transactions which are repeatedly performed.

A ‘server’ as used herein encompasses a computing device operable for receiving or the sending of data across a network. A server may also provide services over the network. For example a server may provide storage or a web service to another computing device. A server may also be referred to as a server computer system.

In one aspect the invention provides for a telecommunication method of securely exchanging unencrypted data between a telecommunications device and a first server via a digital cellular wireless telecommunications network. A server as used herein encompasses a computational device that is able to store and/or provide data over a network connection. The telecommunications device is a battery-powered mobile end-user telecommunications device. The telecommunications device for example, but not limited to: is a mobile telephone, a smart phone, and a tablet.

The method comprises the step of encrypting the unencrypted data using a first encryption algorithm into first encrypted data by the telecommunications device. The telecommunications device may for example, but is not limited to be a mobile telephone, a computing device which connects over a mobile telephone device, or a tablet. The method further comprises the step of sending the first encrypted data to a second server via a first network connection of the digital cellular wireless telecommunications network via the telecommunications device. The method further comprises the step of storing the first encrypted data via the second server. The method further comprises the step of sending an order request to the first server via a second network connection of the digital cellular wireless telecommunications network by the telecommunications device. The order request could for instance be a purchase in an online shop. The method further comprises the step of sending a data publishing request to the second server via the first network connection by the telecommunications device.

The data publishing request may be a request by the telecommunications device to provide the first server with data by the second server. The method further comprises the step of generating a cryptographic key pair by the second server in response to the data publishing request. The cryptographic key pair comprises a public key and a private key. The cryptographic key pair is a cryptographic key pair which is used to fulfill the data publishing request and after this is finished the cryptographic key pair may be deleted. The method further comprises the step of sending the first encrypted data, the public key and the private key to the telecommunications device in response to the data publishing request via the first network connection by the second server. The method further comprises the step of decrypting the first encrypted data into the unencrypted data by the telecommunications device. This may be accomplished using the first encryption algorithm. The first encryption algorithm may for instance be an alternative public key or an asymmetric encryption algorithm or the first encryption algorithm may be a symmetric encryption algorithm. The method further comprises the step of encrypting the unencrypted data into second encrypted data using the public key by the telecommunications device. The public key is an encryption key and the private key is used for decryption.

The method further comprises the step of sending the second encrypted data to the second server via the first network connection by the communications device. The method further comprises the step of generating a web service for providing the second encrypted data via a URL by the second server. The method further comprises the step of sending the URL to the telecommunications device via the first network connection by the second server. The method further comprises the step of sending the URL and the key to the first server via the second network connection by the telecommunications device. The method further comprises the step of requesting the second encrypted data from the second server by the first server using a wired network connection to access the web service at the URL. The method further comprises the step of sending the second encrypted data to the first server by the second server using the wired network connection in response to the request of the second encrypted data by the second server. The method further comprises the step of decrypting the second encrypted data by the first server into the unencrypted data using the public key. The method further comprises the step of combining the order request with the unencrypted data by the first server.

This method may have the benefit that the telecommunications device can securely send the unencrypted data to the first server. The method may further have the benefit that the unencrypted data does not need to be stored on the telecommunications device. For instance if the telecommunications device were lost the unencrypted data for instance may be extracted from its memory or storage. Storing the data on the second server prevents this from happening. The method may also further have the benefit that the second server provides the data to the first server so that the first server is more confident that the data is authentic. For example a malicious software could be installed on the telecommunications device. That the data is provided via the second server may provide more confidence that the data is authentic.

In another embodiment the combining the order request with the unencrypted data by the first server comprises taking all or a portion of unencrypted data and adding it or concatenating it with the order request. For instance the unencrypted data may provide private details or payment data that may be combined with the order request.

In another embodiment the web service becomes inoperative after a predetermined duration. In this example the first server is able to retrieve the second unencrypted data only for a predetermined duration. After this the URL becomes inoperative and the first server can no longer retrieve the second unencrypted data. This provides more security that the second unencrypted data will not be stolen.

In another embodiment the method further comprises the step of deleting the unencrypted data, the second unencrypted data, the URL, and/or the public key after combining the order request with the unencrypted data by the first server. This embodiment has the benefit that the first server removes the data and encryption keys after it has been used. This provides a higher level of security that the data will not be stolen.

In another embodiment the first server is prevented from storing the unencrypted data after combining the order request by a security application. A security application as used herein encompasses executable code in the form of a program or application but controls how the unencrypted data and the subsequent encrypted unencrypted data is handled by the first server. Reception of the second encrypted data by the second server from the first server using the wired network connection to access the web service at the URL is performed by the security application. This step may have the benefit that since the security application handles the access to the URL other software programs on the first server are not able to handle the second encrypted data or the unencrypted data. The decrypting of the second encrypted data by the first server into the unencrypted data using the private key is performed by the security application.

In another embodiment the reception of the order request from the telecommunications device to the first server via the wired network connection is performed by the security application.

In another embodiment the method further comprises sending a data request from the first server to the telecommunications device via the first network connection in response to the order request. The method further comprises redacting the unencrypted data in accordance with the data request before encrypting the unencrypted data into the second encrypted data. This may be beneficial when in order to combine the order request with the unencrypted data not all of the data in the unencrypted data is required. This may provide a higher level of the data security.

In another embodiment the unencrypted data comprises payment data and/or address data.

In another embodiment the second server is a cloud storage server.

In another embodiment the first server is an online shop.

In another embodiment the method further comprises the step of deleting the second encrypted data from the telecommunications device after sending the second encrypted data to the second server via the first network connection.

In another embodiment the method further comprises the step of deleting the unencrypted data from the telecommunications device after encrypting the unencrypted data into the second encrypted data using the public key.

In another embodiment the method further comprises the step of deleting the unencrypted data from the telecommunications device after encrypting the unencrypted data into the first encrypted data.

In another embodiment the method further comprises deleting the first encrypted data from the communications device after sending the first encrypted data to the second server.

The steps of deleting data from the telecommunications device may have the benefit that if the deleted data has been deleted it is impossible to have it stolen or lost if the telecommunications device is lost or stolen.

In another aspect the invention provides for a second server for exchanging unencrypted data between a telecommunications device and a first server via digital cellular wireless telecommunications network. The telecommunications device is a battery-powered mobile end-user telecommunications device. The second server comprises a memory for storing machine-executable instructions. The second server further comprises a processor for executing the machine-executable instructions. Execution of the machine-executable instructions causes the processor to receive first encrypted data via a first network connection of the digital cellular wireless telecommunications network from the telecommunications device. Further execution of the instructions causes the processor to store the first encrypted data. Further execution of the instructions causes the processor to receive a data publishing request via the first network connection from the telecommunications device.

Further execution of the machine-executable instructions causes the processor to generate a cryptographic key pair by the second server in response to the data publishing request. The cryptographic key pair comprises a public key and a private key. Execution of the instructions further causes the processor to send the first encrypted data, the public key, and the private key to the telecommunications device in response to the data publishing request via the first network connection. This for instance may be done using a web protocol that encrypts the data. Execution of the instructions further causes the processor to receive a second encrypted data from the second server via the first network connection from the communications device. Execution of the instructions further causes the processor to generate a web service for providing the second encrypted data via a URL. Execution of the instructions further causes the processor to send the URL to the telecommunications device via the first network connection. Execution of the instructions further cause the processor to receive a request for the second encrypted data from the second server from the first server using a wired network connection to access the web service at the URL. Execution of the instructions further cause the processor to send the second encrypted data to the first server using the wired network connection in response to the request of the second encrypted data by the second server.

It is understood that one or more of the aforementioned embodiments of the invention may be combined as long as the combined embodiments are not mutually exclusive.

DETAILED DESCRIPTION

Like numbered elements in these figures are either equivalent elements or perform the same function. Elements which have been discussed previously will not necessarily be discussed in later figures if the function is equivalent.

FIG. 1 shows an example of a telecommunications system. The system comprises a telecommunications device 100 which is connected via a wireless telecommunications connection 102 to a base station 104. For instance the telecommunications device could be a mobile telephone or a smart phone. The base station 104 is connected via a wired network connection 106 to a first server 108 and a second server 110. The first server 108 and the second server 110 may be computer processing devices for computer systems.

The telecommunications device 100 is shown as comprising a transceiver 112, a processor 114 and a battery 120, storage 118, and memory 120. The storage 118 is shown as containing unencrypted data 122, an encryption key 124, an order request 126, a data publishing request 128, a public key 130, a private key 132, first encrypted data 134, second encrypted data 136 and a URL 138.

The memory 120 is shown as containing a control module 142 which contains executable code which enables the processor 114 to run and control the telecommunications device 100. The memory 120 is further shown as containing a first encryption algorithm 144 that works with the encryption key 124. The first encryption algorithm 144 may for example be a symmetric or a symmetric encryption algorithm. The computer memory 120 is further shown as containing a public key pair encryption algorithm 146 that works with the public key 130 and the private key 132. The contents as shown in the storage 118 and the memory 120 may not be present within the memory 120 or the storage 118 at the same time. Various contents of the storage 118 may be deleted at various points within execution of the method.

The first server 108 is shown as containing a network interface 160, a processor 162, an optional user interface 164, storage 166 and memory 168.

Likewise the second server 110 is shown as containing a network interface 170, a processor 172, an optional user interface 174, storage 176, and memory 178. The contents of the storages 166, 176 may not all be present at the same time. Likewise the contents of the memories 168, 178 may also not all be present at the same time too.

In examining the second server 110 the storage 176 is shown as containing a data publishing request 128 received from the telecommunications device 100. The computer storage 176 is further shown as containing a first encrypted data 134 that was received from the telecommunications device 100. The computer storage 176 is further shown as containing a public key 130 and the private key 132 which were generated by the second server 110. The computer storage 176 is further shown as containing second encrypted data 136 that was received from the telecommunications device 100. The computer storage 176 is further shown as containing a URL 138 for a web service generated by the second server 110.

The memory 178 of the second server 110 is shown as containing a control module 156 which contains computer executable code which enables the processor 172 to operate and function the second server 110. The memory 178 is further shown as containing a key generation algorithm or module 150. The key generation module 150 contains code which enables the processor 172 to generate the private key 130 and the public key 132. The memory 178 further contains a web service generator 152 which provides the URL 138 and also execution of the web service to provide the second encrypted data 136 via the network connection 106.

The first server 108 in the memory 168 is shown as having a security module or security application 154. The security module 154 contains code which enables the processor 162 to execute the method. The use of the security module 154 may be beneficial because it prevents other programs being executed by the processor 162 from having access to data that is being processed. The memory 168 of the first server 108 is further shown as containing second encrypted data 136 and a URL 138. The computer memory 168 is further shown as containing an order request 126 that was received from the telecommunications device 100. The computer memory 168 is further shown as containing a private key 132 that was received with the URL 138 from the telecommunications device 100. The private key 132 can be used to decrypt the second encrypted data 136.

The computer memory 168 is further shown as containing unencrypted data 122 that was encrypted from the second encrypted data 136 using the private key 132 by the security module 154. The computer memory 168 is further shown as containing combined data 140. The combined data 140 is a combination of the order request 126 and the unencrypted data 122. The memory 168 is further shown as containing a public key pair encryption algorithm 146 which may be used by the security module 154 to use the private key 132 to decrypt the second encrypted data 136. The memory 168 is further shown as containing a control module 148 which contains code or instructions to enable the processor 162 to control the operation and function of the first server 108. The memory 168 is further shown as containing a security module or security program 154.

The security module contains code which enables the processor 162 to receive and process data received from the telecommunications device 100 and the second server 110 securely. For example the various pieces of data are illustrated as being contained in the memory 168 instead of in the storage 166. In this particular example this may provide more security because the security module 154 maintains all of the data within the memory and does not store it in the storage 166 where it may be accessible to other programs or applications being run on the first server 108. Not all contents of the storage 166 and the memory 168 may be present at the same time. Various variations of the method may involve deleting various pieces of the data to protect them.

FIGS. 2a and b show a flowchart which illustrates an example of a method. The method shown in FIGS. 2a and 2b can be used to operate the telecommunications system of FIG. 1. First in step 200 the telecommunications device 100 encrypts the unencrypted data 122 into the first encrypted data 134 using the encryption key 124 with the first encryption algorithm 144. Next in step 202 the telecommunications device 100 sends the first encrypted data 134 via the wireless telecommunication link 102 to the base station 104 which then forwards the first encrypted data 134 to the second server 110. In step 204 the first encrypted data 134 is stored by the second server 110. Then in step 206 the telecommunications device 100 sends an order request 126 to the first server 108 via a second network connection that is formed by the wireless telecommunication connection 102 and the wired network connection 106. Next in step 208 the telecommunications device 100 sends a data publishing request 128 to the second server 110 via the first network connection.

In step 210 the second server 110 generates the cryptographic key pair which comprises the public key 130 and the private key 132 in response to receiving the data publishing request 128. Next in step 212 the second server 110 sends the first encrypted data 134, the public key 130, and the private key 132 to the telecommunications device 100 in response to the data publishing request 128 via the first network connection. In some alternative examples the telecommunications device deletes the unencrypted data 122 after it has been encrypted into the first encrypted data 134. Next in step 214 the telecommunications device 100 decrypts the first encrypted data 134 into the unencrypted data 122 using the encryption key 124 and the first encryption algorithm 144. Next in step 216 the telecommunications device 100 encrypts the unencrypted data 122 into the second encrypted data 136 using the public key 130. Next in step 218 the telecommunications device sends the second encrypted data 136 to the second server 110 via the first network connection. Then in step 220 the second server 110 generates a web service for providing the second encrypted data via a URL 138 by the second server.

In step 222 the second server 110 sends the URL 138 to the telecommunications device via the first network connection. In some examples step 222 and step 212 are combined together in one step. Next in step 224 the telecommunications device 100 sends the URL 138 and the private key 132 to the first server 108 via the second network connection. Next in step 226 the first server 108 requests the second encrypted data from the second server 110 using a wired network connection 106 to access the web service at the URL 138. In step 228 the first server 108 sends the second server 110 the second encrypted data 136 in response to the request of the second encrypted data 138 by the second server. Next in step 230 the first server 108 decrypts the second encrypted data 136 into the unencrypted data 122 using the private key 132. Then finally in step 232 the first server 108 combines the order request 126 with the unencrypted data 122. In some examples combining the order request with the unencrypted data may mean processing an order or processing a financial transaction. In other cases the data is simply combined or concatenated.

FIG. 3 shows a flowchart which illustrates an alternate method. In this case the telecommunications device is represented as a user. The second server 110 is a cloud service for providing privacy data and the first server is a shopping website. In a first step the user's data is registered and storage and all data is encrypted and stored using a particular decryption key 300 on the cloud service. Next in step 302 the user requests to buy a book from the shopping website 108. Next the user sends a request to the cloud service to publish the data that the user has stored on the cloud service. This leads to the cloud service in step 306 generating the web service or other format of data. Then in step 308 the cloud service sends the URL to the user 100. The user then provides the decrypt key and the URL in step 310 to the shopping website. The shopping website then retrieves the decrypted data in step 312 from the cloud service. The shopping website can then decrypt the data and delivers the book 314 to the customer. In step 316 the user gets the book. In step 318 the web service for the URL expires. Now all steps performed in FIG. 2 are shown in FIG. 3 or 4.

FIG. 4 shows a further alternative method with several steps added. After step 304 the user client uses the encryption key to decrypt the data which is needed to be published and the encrypt key and encrypt using another decrypt key. The newly encrypted data is then sent to the web service in step 306 or the method proceeds as was illustrated in FIG. 3.

Examples may have one or more of the following benefits:

• • 1. Personal data is kept in one place which can be published to others. (i.e., if you shop on internet you should tell the seller your address)
  • 2. All stored data is encrypted and the main password key is held by the end user.
  • 3. When one needs to provide sensitive data the data can be provided selectively:
    • a. User just provide with limited information. Use a temporary URL with a temporary password key in it (for example: address info or phone number or both, depends on concrete scenario.)
    • b. Information is published in limited period .ex: just valid in 2 days or 8 hours.
    • c. All published data also be encrypted and the key is just sent to the specific (with the temporary URL or other format) target. For example, Data is published to website A and B, but A and B hold different key and access the data by different URL (or other connection)

An example of an additional method is:

• • 1. Maintain privacy information on the privacy cloud service website
    • 1.1 User inputs his privacy information on the privacy cloud service website.
