A biometric method, a biometric apparatus, and a biometric data encryption method thereof are disclosed. In the biometric method and the biometric apparatus, a biometric data is quantified to obtain a quantified data. A one-way function is then performed to convert the quantified data into an encrypted data. In the present invention, the biometric data is protected through a cryptography system so as to prevent the biometric features from being stolen or misappropriated. Moreover, in the present invention, a biometric technique can be integrated with a cryptography technique.

Biometric method and apparatus and biometric data encryption method thereof

A network reputation system and its controlling method are provided. A credential and exchange component permits a user to generate credentials and exchange matching items with those persons having a social relationship with the user. A reputation evaluation component enables other users to make evaluations about an estimatee via the sharing of social network information. A query and response component receives a query from a person having a social relationship with the user for requesting an evaluation about the estimatee, and responds with an associated evaluation result to the person having a social relationship with the user, via the sharing of social network information and the evaluations made by the other users about the estimatee.

Method for sending and receiving an evaluation of reputation in a social network

An authentication system for a wireless network is disclosed. The authentication system includes a card, a card reader, an end-user device, and a wireless access device. The card reader is coupled to the wireless access device. The card records a data, and the card reader reads the data recorded in the card. The wireless access device receives the data read by the card reader and performs authentication between the wireless access device and the end-user device according to the data.

Authentication system and method thereof for wireless networks

A handover authentication method includes performing, by a wireless network server, a first authentication between a client and the wireless network server via a first network gateway; obtaining first authentication keys for the wireless network server and the client based on the first authentication; determining, by the wireless network server, a need to handover the client from the first network gateway to a second network gateway; deriving, by the wireless network server and from the first authentication keys, a handover authentication key shared by the client and the wireless network server; obtaining, by the wireless network server, second authentication keys for the network server and the client; and serving, by the wireless network server, the client via the second network gateway.

Method and system for handover authentication

Disclosed is a computerized apparatus and method for version control and management. The apparatus includes a cryptography boot loader, a control module on key usage, and one or more agents. After the user's device is powered on, the cryptography boot loader stores a user key, and checks an operating system (OS) certificate for an OS and an application certificate for an application to determine whether these certificates are valid. Then, a right object is obtained with a user certificate through an agent. The control module on key usage compares the OS version and the application version with the version required by the right object. The permission access to the user key is determined by the comparison result. This invention associates the cryptography component with the boot loader to develop a security mechanism performed by OS and application for using a secret key.
