Wireless Device Content Information Theft Protection System

Abstract

A wireless device, such as a laptop computer or a cellular phone, may contain confidential information which may be secured by an internal security system. When the device is stolen, the user can provide a portion of a kill code to a wireless service provider. The wireless service provider provides its own portion of the kill code and combines it with the user's supplied code. Then, the service provider may transmit the combined kill code to the wireless device. Upon receipt, the wireless device may erase all confidential information on the device. In other embodiments, it may erase any unlocked block of memory. As still another alternative, the system may also, upon receipt of the combined kill code, disable the operating system.
