A first memory unit is arranged outside a block that is under security control. The block includes: a second memory unit; an acquisition unit for acquiring biological information on a living body from a captured image of a location of the living body; an encryption unit for encrypting attribute information with an encryption key; a registration unit for registering encrypted attribute information encrypted by the encryption unit into the first memory unit, and registering the biological information and the encryption key into the second memory unit; and a presentation unit for decrypting the encrypted attribute information with the encryption key and presenting the attribute information decrypted to the service provision server if the biological information registered in the second memory unit and biological information acquired by the acquisition unit coincide with each other.
