| 20080244271 | METHOD AND SYSTEM FOR AUTHENTICATION BASED ON WIRELESS IDENTIFICATION, WIRELESS IDENTIFICATION AND SERVER - The invention discloses a method and a system for authentication based on a wireless identification, and a wireless identification. The method comprises steps of: obtaining, by a mobile device, wireless tag information and connection configuration information from the wireless identification; establishing, by the mobile device, a connection with the server according to the connection configuration information, and transmitting, by the mobile device, the wireless tag information to the server; authenticating, by the server, the validity of the wireless tag information, and determining, by the server, an access right of the mobile device after the authentication is successful; generating, by the wireless identification, device signature information and forwarding it, by the mobile device, to the server; and authenticating, by the server, the validity of the device signature information, and canceling, by the server, the access right of the mobile device. The present invention provides an authentication system based on the wireless identification, wherein the server authenticates not only the wireless tag information, but also the device signature information generated by the wireless identification, thereby the system is of a higher security. | 10-02-2008 |
| 20090055647 | Auxiliary display system, device and method - The present invention provides an auxiliary display system, device and method. The auxiliary display system includes a client and a server. The client includes an auxiliary display unit which further includes a security module. The server generates information to be shown in the auxiliary display unit, and uses a shared encryption key of the auxiliary display unit to encrypt the information. The security module uses the shared encryption key to verify validity of encrypted information from the server, and decrypts the encrypted information so that the decrypted information will be shown in the auxiliary display unit. The present invention can prevent from forging the auxiliary display information by malicious programs and provide users with reliable information display, and improve experience of the users. | 02-26-2009 |
| 20090254749 | COOPERATION METHOD AND SYSTEM OF HARDWARE SECURE UNITS, AND APPLICATION DEVICE - The present invention provides a cooperation method of a mobile hardware secure unit and a fixed hardware secure unit, comprising: providing user's identification information of a mobile hardware secure unit; providing platform's identification information of a computer-based or other-device-based fixed hardware secure unit; establishing a bidirectional communication pipe between the mobile and fixed hardware secure unit; and binding the mobile and fixed hardware secure units through interaction of the user's identification information and the platform's identification information. The present invention further provides a cooperation system of a mobile hardware secure unit and a fixed hardware secure unit as well as a computer device, with which the security solution based on a fixed hardware secure unit can be combined with a mobile hardware secure unit securing a user's identity. | 10-08-2009 |
