An NFC device according to the present invention includes the following units. An antenna unit receives radio waves from a reader/writer by NFC. A first power source unit generates power from the radio waves. A second power source unit is a drive power source. A power-supply state holding unit holds information indicating a power-supply state of the second power source unit. An NFC unit performs NFC via the antenna unit to transmit the information indicating the power-supply state of the second power source unit. A power source switch unit switches the second power source unit to the first power source unit according to the power-supply state of the second power source unit, in order to supply power to activate at least the NFC unit and the power-supply state holding unit.

A measurement device measures vital data, encrypts the vital data using an encryption key to generate encrypted vital data, and generates, from a decryption key of the vital data, two pairs of a first share FSD and a second share SSD which enable reproduction of the decryption key. The measurement device generates an encrypted second share by encrypting the second share SSD. The measurement device transmits the encrypted vital data, the first share FSD, and the encrypted second share to a server device via an intermediate device.

An authentication system, including a service use device 1 which presents blurred information obtained by blurring certification information desired to be certified, service providing devices 3a to 3c which verify the validity of blurred information presented by the service use device 1, and an authentication device 2 which supports the service use device 1 to issue valid blurred information. The authentication device 2 adds a digital signature to information including certification information and blurred information, and generates authentication information including the obtained digital signature, certification information, and blurred information (S2). The service use device 1 generates, based on the authentication information generated in the authentication device 2, blurred authentication information including blurred information selected according to an instruction from a user, instruction information representing the instruction, and a digital signature (S4). The service providing devices 3a to 3c verify the validity of blurred information indicated by instruction information included in the blurred authentication information generated by the service use device 1, based on the digital signature included in the blurred authentication information (S6).
