Anti-theft device utilizing a heartbeat signal

Abstract

The anti-theft device for securing an electronic gadget against theft. An electric circuitry is configured to generate a heartbeat signal, which the electronic gadget is configured to detect. A security software application is deployed on the electronic gadget. The security application is configured to detect the predefined security signal and verify its authenticity. If a security event occurs, transmission of the heartbeat signal ceases. If the electronic gadget fails to detect the heartbeat signal or the security application fails to verify its authenticity, the security application transitions the electronic gadget into an alarm state, in which the hardware components of the electronic gadget are used to output an alarm signal, which may be a visual alarm, an audible alarm, or a wireless transmission.
