Abstract: A mandate processing device includes: a mandator setting unit, a mandate content setting unit, and a mandatary setting unit, which serve as a first presentation unit that, when a mandate is to be issued from a mandator to a mandatary, presents, as first input candidates, mandate information candidates, which can be determined based on user information of the mandator and the mandatary; a mandate condition setting unit serving as a second presentation unit that presents, as second input candidates, mandate condition candidates, which are the mandate information candidates other than the first input candidates and which are candidates for a mandate condition defined by the mandator as a condition for the mandatary; and a mandate information registration unit that registers mandate information which is information selected from the first input candidates and the second input candidates and for performing the mandate.

Abstract: A first computer, in data registration processing: determines a type of biometric information for encryption with which the data is to be encrypted; acquires the determined type of biometric information for encryption from a user of the first computer; generates, from each piece of the acquired biometric information for encryption, a public key based on a predetermined algorithm; transmits the public key to a second computer; and transmits the data encrypted with the public key to the third computer, the first computer, in data presentation processing: acquires the encrypted data from a third computer; acquires the determined type of biometric information for decryption from the user of the first computer; generates, from each piece of the acquired biometric information for decryption, a private key based on the predetermined algorithm; decrypts the encrypted data with use of the private key; and presents each piece of the decrypted registered data.
