In a device registration system, user authentication and device authentication of a CE device are executed in a single session, and the user and the CE device are associated with each other if these authentications succeed. The CE device obtains information for user authentication from an IC card and portable memory, and sends the information and device authentication information to a device registration unit. The device registration unit sends the information for the user authentication to a user authentication unit, and the device authentication information to a device authentication unit. The user authentication unit executes a user authentication process and sends information of the user to the device registration unit if authentication succeeds. The device authentication unit executes a device authentication process and sends information of the device to the device registration unit if authentication succeeds. The device registration unit associates user information and device information with each other.

In a device registration system, user authentication and device authentication of a CE device are executed in a single session, and the user and the CE device are associated with each other if these authentications succeed. The CE device obtains information for the user authentication from an IC card and a portable memory, and sends the information and device authentication information to a device registration unit. The device registration unit sends the information for the user authentication to a user authentication unit, and the device authentication information to a device authentication unit. The user authentication unit executes a user authentication process and sends information of the user to the device registration unit if the authentication succeeds. The device authentication unit executes a device authentication process and sends information of the device to the device registration unit if the authentication succeeds. The device registration unit associates the user information and the device information with each other.

The present invention relates to an information processing system, and an information processing apparatus and method in which authentication processing on a network can be easily performed. A setting terminal device sends registration information input by a user to a CE-device registration setting server. The CE-device registration setting server generates connection information for connecting CE devices to the Internet based on the registration information. The setting terminal device receives the connection information from the CE-device registration setting server and stores it in a memory card. When the memory card is attached, the CE device reads the connection information so as to connect to a network. The present invention can be applied to electronic devices connected to a network.

Information processing system, and information processing apparatus and method

A device authentication module and an encryption module can be connected via a dynamic link in a CE device. A random number is generated in an authentication server (). The device authentication module () combines a pass-phrase and this random number to generate a digest, and transmits this and a device ID to the encryption module (). The encryption module encrypts a communication pathway and transmits these items of information to the authentication server (). The authentication server () searches for the pass-phrase based on the device ID and combines this and the generated random number to generate a digest. This digest is compared with the digest received from the encryption module () for device authentication. The encryption module () receives from the device authentication module () not the pass-phrase but a digest, and therefore can be connected via a dynamic link instead of a static link.

Device authentication system

This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE devicerequests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication serverThe surrogate authentication serverauthenticates the CE devicebased on the authentication information and transmits a result of the authentication to the service serverIn turn, the service serverprovides the CE devicewith the requested service based on the result of the authentication received from the surrogate authentication serverThe CE devicethen uses the service provided by the service serverThis system can be applied advantageously to network-based marketing systems.
