摘要： A method and system for providing access to information on an article to which a tag is coupled. A local server reads the tag containing a virtual ID that includes an encryption of a bit string. The bit string includes an article ID containing a manufacturer ID. The local server is coupled to an ONS server, an ONS proxy server, and a PML server via a network. The local server sends to the ONS proxy server an ONS service request that includes the virtual ID and requests a network address of the PML server. The local server receives, from the ONS server, the network address of the PML server. The local server sends to the PML server, at the network address of the PML server, a PML information request that includes the virtual ID and requests article information. The local server receives, from the PML server, the article information.

摘要： A database search system ensures the privacy of a search request and the security of a database with high processing efficiency. The system comprises a database server residing on a network that stores predetermined data, and a client terminal issuing to the database server a search request for inquiring for desired data while keeping the desired data secret. The database server further comprises: a database storing predetermined data; and a search response message generation unit for receiving through a network the data search request in which data to be searched for is kept secret, searching the database by a predetermined computation based on the search request and a list of the data stored in the database while a data item involved with the search request is kept secret, and generating a response to the search request.

摘要： Cryptographic communication system including a sender terminal for encrypting and transmitting a message, a recipient terminal for receiving and decrypting the encrypted message, an agent terminal for decrypting the message in place of the recipient terminal, and a conversion server for supporting the agent terminal to decrypt the message. The sender terminal encrypts the message using a public key of the recipient terminal. Using a public key of the conversion server, a predetermined restricted condition, and a secret key for decryption of the message, the recipient terminal generates a delegation key allowing decryption of the message under the restricted condition and passes the delegation key to the agent terminal. The conversion server validates a power of the agent terminal to decrypt the message based on the information contained in the delegation key from the agent terminal. The agent terminal then decrypts the message with validation of the conversion server.

摘要： The present invention provides an apparatus for verifying the authority of an owner, in terms of an identifier of a product, the first verification information for verifying the authority held at a terminal for an owner with the authority involving the product, and the second verification information for verifying the authority concerning the identifier of the product stored in a product database. The apparatus comprises means for receiving the identifier and the first verification information, means for acquiring the second verification information from the product DB, and means for determining whether or not there is the authority from the first verification information and the second verification information. A hash value acquired from a one-way hash function is employed as a verification key of the verification information.
