  • Patent number: 8401244
    Abstract: Systems and methods for providing secure identity authentication amongst devices using identity information contained therein to facilitate data synchronization amongst the user devices, wherein the identity information in the devices are compared for authentication but not actually transmitted or exposed for unauthorized access to such information and to the devices.
    Type: Grant
    Filed: December 21, 2007
    Date of Patent: March 19, 2013

  • Patent number: 8364120
    Abstract: The identity of a user of a mobile device is verified by the mobile device accessing the location of the mobile device over recent time to obtain a current route, comparing a feature of the current route to characteristic features of previous routes stored on the mobile device. The user is verified if the feature of the current route matches a characteristic feature of previous routes. The previous routes may be obtained by tracking the location of the mobile device over time to obtain a number of routes, identifying characteristic features of the routes, and storing the characteristic features of the routes.

  • Publication number: 20090276823
    Abstract: A method and apparatus for modifying a color of an electronics housing (104) based on the device security, authentication, and/or authorization is provided herein. During operation a device (100) will repeatedly gather a current security status and then modify a color or pattern of the housing based on the security status. Because the color of an electronics device indicates the current security, authentication, and/or authorization level, a user of the device can easily determine their security, authentication, and/or authorization level.

  • Patent number: 7596812
    Abstract: Disclosed is a method, system and apparatus for transferring protected data having an authorizing entity's outer encryption layer and having a user-fixed inner encryption layer from a first electronic device having a first unique, unalterable identifier to a second electronic device having a second unique, unalterable identifier. A central unit includes a receiver configured to receive from the first electronic device protected data having an authorizing entity's first outer encryption layer corresponding to the first unique, unalterable identifier and having a user-fixed inner encryption layer; a processor configured to decrypt the authorizing entity's first outer encryption layer of the protected data; a processor configured to encrypt an authorizing entity's second outer encryption layer of the protected data corresponding to the second unique, unalterable identifier; and a transmitter configured to transmit protected data to the second electronic device.

  • Patent number: 7522915
    Abstract: A communications device (300) enabled to support both external voice communications functionality (301) (or other external communications of interest and choice) and other functionality (302) has at least a first and second mode of operation (304 and 305). The first mode of operation permits essentially all functionality while the second mode of operation precludes at least much of the other functionality in favor of preserving the viability of at least some of the external communications functionality. A selector (306) can select a given mode of operation based, at least in part, on a trigger 307 comprising, for example, a user input and/or detection of a condition of concern.
