According to one embodiment, a policy update system includes a server apparatus configured to be able to provide a plurality of services to a user, the server apparatus including storage device for storing a first user ID; a policy storage device configured to store a plurality of policies, each policy being composed of condition describing user attribute information in which a plurality of items including a second user ID corresponding to the first user ID are associated, and each policy specifying a use privilege of each service; a policy update apparatus configured to be able to update each stored policy; and a user attribute information storage device configured to store post-change user attribute information, and a change content for each second user ID.

Policy update system and policy update apparatus

According to one embodiment, a policy management system includes a user terminal, an ID provider system which manages an identity of a user, and a service provider system which provides service data. The ID provider system stores a pair of an old policy and a new policy with respect to each service provider ID. The ID provider system stores information with respect to each service provider ID, the difference-adaptive definition information defining a first condition which is referred to when a date of transmission of an access request message is within a transition period from the old policy to new policy, and a second condition which is referred to when the date of transmission of the access request message is out of the transition period.

An authentication device receives each authentication context including an output information block, an input information block, and an authenticator block. The output information block includes a process result and process result identification information. The input information block includes a process result and process result identification information. The authentication device verifies each authenticator block. The authentication device searches for the output information block having the same value of process result identification information as the value of process result identification information in the input information block from other authentication contexts based on process result identification information in the input information block included in each authentication context. The authentication device verifies whether or not the process result in the input information block is equal to the process result in the searched output information block, and authenticates that all the authentication contexts have validity when all the verification results are valid.

System and device for authentication

According to one embodiment, the ID provider device stores pieces of policy information for each service provider ID. The ID provider device outputs a policy evaluation request including the user ID used in the log-in processing and the service provider ID in the authentication federation request when the log-in processing is successful. The ID provider device reads the policy information in accordance with the service provider ID in the policy evaluation request. The ID provider device judges whether to permit the transmission of the service data in accordance with whether environmental conditions of the user for the execution of a service conform to the read policy information.

Authentication federation system and ID provider device

A policy storage unit of an ID provider device according to an embodiment stores, for each service provider ID, policy information representing a user to which transmission of service data is permitted and policy information representing a user of a target in which transmission permission of service data is deleted. When a predetermined cycle comes or when a use status of the service provider device changes, the ID provider device acquires use status information of the service provider device transmitted from the service provider device, and updates a service use status storage unit based on the acquired use status information. When the service use status storage unit is updated, the ID provider device decides a deletion target account of each service provider ID.

A client apparatus receives a message including a random number from a server apparatus during the handshake of agreement process, creates a biometric negotiation message including the biometric authentication method information and sends the biometric negotiation message to the server apparatus. Then, the client apparatus executes a biometric authentication based on biometric authentication method information notified from the server apparatus and encrypts the random number based on the private key. In addition, the client apparatus generates an authenticator from a result of the biometric authentication, the biometric authentication method information, the encrypted random number, and the client certificate, and sends to the server apparatus an authentication context including these. The server apparatus verifies the authentication context and establishes a secure session in one handshake.
