A recording medium stores an information processing program that causes a computer having a storage unit storing therein a file group in which character code strings are described, to execute generating combined identification information by dividing into two portions, at least one among identification information for a preceding character code and identification information for a succeeding character code and respectively combining the portions with the identification information that is not divided, the preceding and succeeding character codes constituting a character code string for two-consecutive grams in a file among the file group; storing to the storage unit, various consecutive-gram divided maps obtained by allocating to each type of combined identification information generated, a string of bits corresponding to the quantity of files in the file group; and updating in the consecutive-gram divided maps, a bit indicating whether the character code string for the two-consecutive grams is present in the file.

Computer product, information processing apparatus, and information search apparatus

A computer-readable recording medium stores therein an information search program that causes a computer to search for text items described in a text file. The information search program causes the computer to execute receiving input of a search keyword; searching an index file for a writing keyword that includes the search keyword, the index file including writing keywords described, for respective entries, in an order identical to the order in which the text items are described in the text file; identifying an entry that corresponds to the writing keyword retrieved at the searching; and outputting the identified entry.

Information search apparatus, and information search method, and computer product

A method for identity verification includes receiving a request for proof of identity from a service provider and receiving biometric information associated with a user of a communication device. The method also includes determining that the received biometric information matches a biometric profile that contains biometric information associated with a registered user of the communication device. The method also includes unlocking a private key associated with the registered user in response to determining that the received biometric information matches a biometric profile and sending a request for a digital certificate that is signed with the private key associated with the registered user. The method further includes receiving the digital certificate that includes a public key associated with the registered user and satisfies the request for proof of identity. The method also includes with forwarding the digital certificate to the service provider.

Method and apparatus for identity verification

An information processing apparatus includes a chip implemented therein to independently perform a predetermined process. The chip includes a storage unit that stores therein user signature information in which biometric information of a user and a user electronic signature key that is a key for generating an electronic signature of the user for information created by the user are associated with each other and an encryption key that is a key for encrypting information, an electronic signature adding unit that, if the biometric information is obtained from the user, searches the storage unit for the user signature information corresponding to the biometric information, and adds the electronic signature of the user to user created information with a user electronic signature key in the user signature information, and an encrypt processing unit that encrypts with the encryption key the user created information processed by the electronic signature adding unit.

Information processing apparatus and information management method

Data processing apparatus distributes a public key certificate and information about a private key to a user terminal as activation information separately from a terminal module. In the case where the public key certification is vulnerable, it transmits only the activation information again.

Data processing apparatus for digital copyrights management

A detailed statement notifying system is connected via the Internet to a consumer terminal, a shop terminal, a credit company terminal and a logo management server. A detailed statement notifying program stored in the detailed statement notifying system is read by a CPU to obtain, when given a notification of consumer's transaction information from the credit company terminal, article information related to the consumer's transaction information from the shop terminal. The detailed statement notifying program further makes CPU obtain, when accessed from the consumer terminal, logo information of a maker of the article or a shop from a logo management server on the basis of the consumer's transaction information and the article information, generate data for displaying a detailed statement screen and transmit the data to the consumer terminal.
