    摘要: A computer extracts the header information from an electronic mail, including an originality guarantee. The computer generates a header characterization for the header information subject to originality guarantee, and extracts message body information from the electronic mail and generates a body characterization for the message body information as well. The generated characterization set applies the header characterization and the body characterization, combined. The verification information is added to the generated characterization set for applying a signature, and characterization set is linked to electronic mail.

    摘要: Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data.At the registration time of new document information, the digital document management program manages a digital signature created in association with document information. At the correction time of the document information, the program acquires partial identification information related to a corrected part of the document information before correction, creates a digital signature to be appended to the corrected document information, and manages the digital signature and partial identification information related to the corrected part of the document information in association with the corrected document information. At the verification time, the program uses partial identification information, the partial identification information corresponding to a corrected part of the document information before correction, and digital signature to perform verification.

    摘要: A communication device includes a data storage unit, a decryption unit, an encryption unit, and a judgment unit. The data storage unit stores a piece of encrypted data or a piece of decrypted data. The decryption unit decrypts each provided piece of encrypted data. The encryption unit encrypts each provided piece of decrypted data. The judgment unit issues an instruction to the encryption unit to read from the data storage unit first decrypted data obtained by the decryption unit decrypting first encrypted data with a cryptographic key, and to write back to the data storage unit second encrypted data obtained by the encryption unit encrypting the first decrypted data with the cryptographic key.
