Abstract
A system for allowing a potential buyer of second-hand of a CE device (60) to look up an identifier of the device (60) in a revocation list (55), in order to determine if the CE device (60) has been partially or full disabled as a result of revocation. The revocation list (55) may be accessible by a user on-line, e.g., on the Internet, or may be stored in a DVD. The CE device (60) may be equipped with a revocation status indicator 61 that, when activated by the user, causes the CE device (60) to access an on-line revocation list (55), look up its revocation status, and output its revocation status to the user. Alternatively, the CE device (60) may include a revocation status indicator (61) that accesses a tamper-resistant storage mechanism (63) in the CE device (60) to determine and output the revocation status.
