  • Patent number: 7225165
    Abstract: The invention enables a provider and a retailer of digital contents to issue an electronic license to a consumer without wasting its own resources. A retailer sells digital contents to a consumer via the Internet. The retailer requests a license-issuing center to issue an electronic license corresponding to the digital contents and the user of the contents and receives the generated license. The user receives the license from the retailer via the Internet. The terminal used by the user certifies that he/she is a legitimate user using his/her license when he/she uses the digital contents provided from the provider. When the license is verified, the user can use the digital contents.

  • Patent number: 7165176
    Abstract: Access privileges of a client are authenticated without using user account data. If an RSA modulus and public key have been assigned to the requested web page, the access privilege authentication controller 105 calls the challenge generator 107 to generate a challenge and transmits this challenge to the client 201 via the I/O controller 102. Subsequently, the access privilege authenticator 104 waits for a response from the client 201 sent via the I/O controller 102. When a response is received from the client 201, the access privilege authentication controller 105 calls the access privilege verifier 108 to verify whether the response is correct. If the response is correct, data indicating that the access privileges have been successfully authenticated is outputted, thereby alloying the client to access the requested service.

  • Patent number: 6996723
    Abstract: Integrity of data is to be ensured in a simple manner. A data verifier generates a signature generation request from data to be signed and signature request time, and sends the request to a data generator. The data generator extracts the data to be signed from the signature generation request, and its signature generation unit generates a signature for the data. A key generation unit generates a key from a previous key, the signature request time in the signature generation request, and the identifier of the data generator, and an encryptor encrypts the signature. After that, the encrypted signature and the like are returned to the data verifier, which generates a decrypting key with a key generation unit from the previous key, the signature request time, and the identifier of the data generator, then extracts an encrypted signature, and decrypts it with a decryptor. A signature verification unit checks whether or not the result of decrypting is the correct signature.

  • Patent number: 6950808
    Abstract: Booking venders are to be enabled to issue booking certificates without having to consume their own resources. Advance booking is made and sent to a retailer from a consumer terminal via the Internet. The retailer requests a booking certificate issuing center to issue a booking certificate associated with the product or the booking party, and receives the booking certificate issued from the booking certificate issuing center. The consumer terminal receives the booking certificate from the retailer via the Internet, and uses it to have itself verified to be the legitimate booking party by a verifying apparatus associated with a provider. The booking party can receive the supply of the booked product or service if its booking certificate is successfully verified.

  • Patent number: 6615352
    Abstract: 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.

  • Patent number: 6567916
    Abstract: 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.

  • Patent number: 6516413
    Abstract: 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! condition that all of challenge data, required security information, access ticket, control information and user identifying information are correct.
