A peripheral device includes an interface for connection to a wired or wireless LAN, a local interface for wireless connection, and a control unit configured to check a legitimacy of a user based on a user-specific certificate stored in a communication-function-equipped device upon being accessed through the local interface by the communication-function-equipped device using near-field wireless communication, and to allow a predetermined process to be performed upon successful authentication of the legitimacy.
