摘要：PROBLEM TO BE SOLVED: To provide a portable terminal which prevents communicative prohibition processing using a wireless communication channel by a third person, in the portable terminal equipped with a so-called remote lock function restricting the functions of the portable terminal from a remote place. SOLUTION: In the portable terminal equipped with a so-called off-line mode forbidding communication using a wireless communication channel which is now used by the portable terminal, a person not using any portable terminal is burdened with user authentication at the time of transition to an off-line mode (step 101), and transition to the off-line mode is performed only when user authentication is successful (step 104). Thereby, the portable terminal is lost, and it is possible to prevent the third person finding this portable terminal from setting the off-line mode. Consequently, since the portable terminal can certainly receive a remote lock signal, a prevention of an information leakage can be aimed. COPYRIGHT: (C)2010,JPO&INPIT
