Mobile terminal and remote locking program storage medium

摘要

A mobile terminal of the kind having detachably mounted thereon a recording medium (106) in which user-specific information is written, and besides the recording medium, having an internal memory (103) holding terminal-specific information, the mobile terminal being designed to perform radio communication whilst the recording medium is mounted thereon. The terminal has a locking instruction determination section (102) which determines whether or not announcement information transmitted to unspecified mobile terminals by radio communication is locking instruction information containing terminal-specific information to instruct locking of a mobile terminal specified by the terminal-specific information; a coincidence determination section which determines whether or not terminal-specific information contained in the locking instruction information coincides with that recorded on the mobile terminal; and a locking section (104) which locks the mobile terminal to disable at least some of the functions of the mobile terminal. In this way, the mobile terminal can be secured in the event of loss, even after the recording medium such as a SIM has been switched or removed.
