摘要： A purchaser apparatus stores “anonymous order information including an order ID and purchaser identity verifying information” and “purchaser identity proving secret information”. A shop apparatus stores “anonymous order information including an order ID and purchaser identity verifying information”. If necessary, a purchaser sends a request including an order ID and zero knowledge proving information that a purchaser knows the purchaser identity proving secret information, from a purchaser apparatus to a shop apparatus. A shop apparatus verifies the zero knowledge proving information, based on purchaser identity verifying information retrieved from an order ID included in the request. Therefore, the unlinkability for past use is eliminated if necessary, and inconvenience caused by the unlinkability is eliminated.

摘要： According to one embodiment, the resource access unit accesses a first resource including a replication target object and policy data assigned to the object. The policy data includes base policy data including a first condition and assertion policy data including a second condition. The first retrieval unit obtains first attribute data for accessing the first resource. The first policy evaluation unit determines whether the first attribute satisfies the first condition. When the first condition is satisfied, the copy processing unit executes the copy processing for copying the object. The second retrieval unit obtains the second attribute data for accessing the second resource. The second policy evaluation unit determines whether the second attribute data satisfies the second condition. When the second condition is satisfied, the paste processing unit executes paste processing for pasting the object to the second resource.

摘要： According to one embodiment, an access control apparatus suspends the resource access event prior to access of the resource access device when the resource access event is started. The access control apparatus acquires attribute information from the attribute management device by using the deny-type policy in the access control policy and decides the permission or the denial of the access based on this attribute information and the deny-type policy. The access control apparatus releases the suspension when a result of decision in the supplied access decision result is indicative of the permission and no obligation-type policy is present in the access decision response.

摘要： A store apparatus receives anonymous order information including an order ID and a group signature from a purchaser apparatus. The store apparatus verifies the group signature. When the group signature is verified to be valid, the store apparatus sells an article corresponding to the anonymous order information and order ID to a purchaser via a manager apparatus so as to keep the name of the article secret. Consequently, the store apparatus, serving as a service provider, need not manage personal information. This enables a user to remain anonymous. Further, the manager apparatus handles the article the name of which is kept secret. This makes it possible to protect the privacy of the contents of the order from the manager apparatus.
