The present invention provides a device-authentication system capable of efficiently performing authentication before using a service through a network. A CE device (3) includes a browser (9) for accessing a service server (4) and an authentication module (7) for allowing an authentication server (5) to perform device authentication. A device-authentication plug-in (8) is a plug-in having a function of starting the authentication module (7). The device-authentication plug-in (8) can be specified by a predetermined MIME format, and the browser (9) starts the device-authentication plug-in (8) after receiving an EMBED tag having the MIME format.
