US 2002/0161454 A1 · Information processing system, information processing apparatus, information terminal, and method for control thereof

Abstract

Disclosed are the information processing apparatus, its system, and method for control of the apparatuses capable preventing surreptitious reading, falsifying and erasing of data stored in the apparatuses. The system comprises information processing apparatus, portable apparatus and other information terminals having radio transmitting and receiving units. It is judged whether the distance between the two apparatuses is within a predetermined range or not by means of radio field strength detector or global positioning system (GPS). If not existing within a predetermined range or the password is not matched, some of the operations of at least one of the two apparatuses are stopped, or start of the two apparatuses is stopped.

Claims26

Dependent claims
