20120144458 | SYSTEM AND METHOD FOR IDENTITY VERIFICATION ON A COMPUTER - A system to verify user identity on a computer uses a server with a set of stored or created images. An image is selected and transmitted over a computer network to the computer whose user identity is to be verified. The user captures the image on a mobile communication device using, by way of example, a built-in camera. The captured image is transmitted via a public mobile network back to the server where the captured image is compared with the stored image. If the images match, the user identity is verified. In another embodiment, multiple images may be displayed and user-selectable options are selected by capturing one of the multiple images. | 06-07-2012 |
20120129492 | SYSTEM AND METHOD FOR TRANSACTION AUTHENTICATION USING A MOBILE COMMUNICATION DEVICE - A transaction authentication system uses a computer network and mobile telephone network to authenticate a user. The user initiates a transaction and provides an identity token, such as the mobile telephone number. The identity token is used by an authentication server to initiate the issuance of a new temporary identity for the corresponding mobile device. The new temporary identity is forwarded from the mobile device to the authentication server which issues a security code if there is a match between the new temporary identities. The security code is forwarded to a transaction server which relays it to the authentication server. If the forwarded security code matches the generated security code, the transaction is permitted to continue. | 05-24-2012 |
20120108203 | SYSTEM AND METHOD FOR ASSURING IDENTITY ON A MOBILE DEVICE - The identity of a mobile communication device can be authenticated to allow the device to access a web site without the need for a user log-in operation. The mobile device stores an identity token and sends it to the web server in the web browser data stream. Additionally, the mobile device transmits an identity token to an authentication entity using a data stream other than the web browser data. The authentication entity queries the wireless network to verify authentication of the mobile device. The identity token may be the mobile telephone number itself, a temporary mobile subscriber identity assigned by the mobile network, or encrypted or hashed versions of either. Alternatively, a new temporary mobile subscriber identity may be sent to the mobile device and retransmitted back to the authentication entity. | 05-03-2012 |
20100260127 | SYSTEM AND METHOD FOR ROBUST TRANSMISSION IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXED COMMUNICATION SYSTEM - A system for robust transmission in an orthogonal frequency division multiplexed (OFDM) communication network is disclosed. An individual wireless communication device is assigned a set of OFDM tones for transmission in an uplink timeslot. If the received signal is not satisfactory, the number of OFDM tones assigned to the individual wireless communication device may be doubled such that the OFDM signal is duplicated in the additional set of OFDM tones. This process can be extended to multiple additional sets of OFDM tones. The multiple sets of OFDM tones may be combined at the base station to enhance recovery of the original transmitted signal. The assigned OFDM tones need not be contiguous within a block of available tones. Because a large number of OFDM tones are available, the concept may be extended to a large number of duplicate sets of OFDM tones. In a Group Call operation, each wireless communication device in the call group may be assigned multiple sets of OFDM tones to provide for more robust transmission. | 10-14-2010 |
20100197334 | SYSTEM AND METHOD FOR PUSH-TO-TALK COMMUNICATION IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXED COMMUNICATION SYSTEM - A system to permit push-to-talk communications in an orthogonal frequency division multiplexed (OFDM) communication network. Individual wireless communication devices that are part of a Group Call are assigned the same set or sets of OFDM tones for a downlink timeslot. Because each wireless communication device receives the same set of tones, each device will receive a communication simultaneously. The assigned OFDM tones need not be contiguous within a block of available tones. Because a large number of OFDM tones are available, the concept may be extended to a large number of groups that each separately support a Group Call function. | 08-05-2010 |
