    • 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.
    • 信息处理装置包括其中实现的芯片以独立地执行预定处理。 芯片包括存储单元,其中存储用户签名信息,其中用户的生物信息和用户电子签名密钥是用户生成用于由用户创建的信息的电子签名的密钥彼此相关联, 作为用于加密信息的密钥的加密密钥,如果从用户获得生物体信息,则在电子签名添加单元中搜索与生物特征信息相对应的用户签名信息的存储单元,并添加用户的电子签名 在用户签名信息中具有用户电子签名密钥的用户创建的信息,以及加密处理单元,其利用用户创建由电子签名添加单元处理的信息的加密密钥进行加密。
