PORTABLE ANTITHEFT DEVICE AND METHOD

摘要

Disclosed in the present invention are an antitheft device and a method, the device comprising: a main control module, at least one first I/O interface, at least one second I/O interface, a connection state detection module and an alarm module. The at least one first I/O interface is connected to a protected electronic device and/or the at least one second I/O interface; the at least one second I/O interface is connected to a charger for the protected electronic device and/or the at least one first I/O interface; the connection state detection module is used for detecting the connection state of the at least one first I/O interface and second I/O interface and reporting the connection state to the main control module; the main control module judges whether the state of the at least one first I/O interface and/or second I/O interface is abnormal or not according to the interface connection state reported by the connection state detection module, and sends a trigger signal to the alarm module if the state is abnormal; and the alarm module performs an alarm action after receiving the trigger signal of the main control module.
