    摘要: Both of a user side and a protect side such as a programmer of an application programmer need not handle a large number of inherent information such as authentication keys. An access ticket generation device generates an access ticket from user unique identifying information and access rights authentication feature information. As unique security characteristic information, there is used a secret key of an elliptic curve encryption or an ElGamal encryption. A proof data generation device receives the access ticket, converts authentication data received from a proof data verification device into proof data by use of the access ticket and the user unique identifying information, and returns the resultant proof data to the proof data verification device. The proof data generation device or the proof data verification device decrypts the above-mentioned encryption. The proof data verification device verifies the access rights as correct access only when a combination of an access ticket and user unique identifying information used in the proof data generation device is correct.

    摘要: 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.

    摘要: The present invention relates to a document structure composing apparatus to judge a short part based upon the structure of the whole document, perform processing for complementation and compose document structure according to a desired document class. Complementation specification storage means stores the specification of complementation for document structure. Complementation means applies processing for complementation to pre-complemented document structure. Correlating rule storage means stores a rule for correlating components between different document classes. Document structure converting means converts an original document which meets the structural constraint of a specific document class to structure according to another document class according to the correlating rule. The original document is first converted from structure according to the specific document class to structure nearly according to a desired document class by the document structure converting means. The correlating rule required for conversion is stored in the correlating rule storage means. Afterward, processing for complementation based upon the specification of complementation stored in the complementation specification storage means is executed by the complementation means and document structure according to a desired document class is composed.

    摘要: A pattern generating apparatus includes a setting unit, an identifying unit, and a generating unit. The setting unit sets a pattern area on a recording medium. The identifying unit identifies a position of the pattern area, which is arranged in a plane having a predetermined size with a specified position in the pattern area located at or substantially at a center of the plane, in the plane. The generating unit generates a pattern into which the identified position is coded.

    摘要: 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.

    摘要: 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.

    摘要: 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.
