Abstract

A system for identifying a lost or stolen device includes a transmitter, a receiver and a computer. The transmitter is coupled to the device and transmits identification information. The receiver receives the identification information transmitted by the transmitter when the transmitter is within a defined distance from the receiver. The computer is coupled to the receiver so as to receive the information from the receiver. The computer has a first secure database which stores data associated with lost or stolen devices and which prevents unauthorized access to the data stored therein. The computer compares the information with the stored data, and generates an alarm if the information matches at least some of the stored data.
