Abstract
An anti-theft and file security system for a portable electronic device that uses a wireless transceiver coupled to the electronic device, which detects an identifying RF signal produced by a wireless access point. In the preferred embodiment, the access point is connected to a local or wide area network within a geographical area in which the portable electronic device is operated. During use, the RF signal from the access point is detected by a wireless transceiver. Loaded into the memory of the electronic device is a software program that determines if the RF signal is produced by a recognized access point. If the RF signal produced by the access point is recognized, then the electronic device continues to operate and allows full access to secured files loaded thereon. If no RF signal is detected or if the detected RF signal is from a non-recognizable access point, then operation of the electronic device is terminated and/or access to the secured file is blocked.
