An information processing device, which is used by a user and includes a storage device, encodes target information required for a device authentication by a server by using device-specific information or information based on the device-specific information as an encryption key, and stores the encoded target information. The information processing device uses a decryption key that corresponds to the encryption key used in the generation of the stored encoded target information to decode the encoded target information, and sends the decoded target information to the server. The server receives the target information from the information processing device, and determines whether or not the received target information is correct. |
