In an information processor (100), a security chip (10) associates the biometric information (information such as fingerprint, iris, vein, or face) of a user with the information of a user electronic signature key for creating an electronic signature of the user and stores it in a user electronic signature key storage section (12), searches, when the biometric information of the user is acquired from a bio-sensor (30), a key for creating an electronic signature corresponding to the biometric information acquired by a cipher/signature processing section (18), attaches the electronic signature of the user to user created information using the searched key, encrypts the user-created information by a cipher key unique to a security chip (10), and transmits it to the destination.
