In response to an instruction to copy data from a first electronic document to a second electronic document, a protected document generating section of a document processing apparatus newly generates a third electronic document as a copying result. A combining requesting section requests combining of pieces of manipulation authority information (policies) to be applied to the first and second electronic documents, respectively. In response to the request, a policy combining section of a policy managing apparatus combines the two pieces of manipulation authority information together into third manipulation authority information. A protected document registering section registers the third electronic document and the third manipulation authority information in a document DB.

A burden caused by handling a large number of unique identifying information pieces such as authentication keys is to be lightened from both the user side and the protector side such as application creators. A proof data verification device sends authentication data to a proof data generation device. Signature data generation means and presignature data generation means in the proof data generation device cooperate with each other to generate proof data (a signature based on a discrete logarithm problem) from the received authentication data as well as held user unique identifying information and an access ticket, and send the proof data back to the proof data verification device. Verification means in the proof data verification device verify the signature, and if the verification is successful, the execution of program is allowed.

Device and method for authenticating user's access rights to resources

A burden caused by handling a large number of unique identifying information pieces such as authentication keys is to be lightened from both the user side and the protector side such as application creators. A proof data verification device sends authentication data to a proof data generation device. The proof data generation device generates proof data from both received authentication data and user unique identifying information held therein and sends it back to the proof data verification device. The proof data verification device holds an access ticket and authentication data, and verification means in the verification device performs a signature verifying calculation by use of the proof data, authentication data, and the access ticket. If the verification is successful, the execution of program is allowed.

The present invention allows even small-size verification devices to authenticate rights and qualifications without leaking authentication characteristic information to third parties. A ticket issuance device computes document private information &mgr; from a private function f of an interaction device owned by a user and document m to be transferred to the interaction device when generating interaction, and issues ticket t generated from authentication characteristic information x and the document private information &mgr; to the user. The interaction device, when document m is input, generates document private information &mgr; using a private function f specific to the interaction device, and performs interaction based on the document private information. The interaction comprises output of commitment r, input of challenge &khgr;, output of response &sgr;, and message M output. The user converts interaction (r, &khgr;, M, &sgr;) into interaction (r, &khgr;, M, s) using ticket t to perform Guillou-Quisquater authentication.

Method and device for authentication

An apparatus and method for user authentication for easily realizing the allocation of a complexity of rights when controlling access by a plurality of users to a plurality of objects. A verification apparatus sends to a proving apparatus required security information that shows the authority property required for access to an object, along with a challenge data and a modulo of a public key. A required security information inspection unit within the proving apparatus obtains the required security information stored in a response data memory and a control information representing a user's authority property stored in a control information memory. It then inspects whether an identifier of:the required security information is included in a list included in the control information. If the identifier is included, a response data is generated, upon&excl; condition that all of challenge data, required security information, access ticket, control information and user identifying information are correct. An access ticket is a result of masking a user's capability, a data representing the extent of his access rights.
