Anti-theft system and operating method thereof
First Claim
1. An anti-theft system, comprising:
- a wearable device comprising a first wireless module, a first processing module and a first positioning module; and
a portable electronic device comprising a second wireless module, a second processing module and a second positioning module, wherein the first wireless module and the second wireless module are in a wireless connection with each other, and the second wireless module detects a received signal strength indicator value of the wireless connection,wherein if the received signal strength indicator value is lower than a predetermined signal strength value, the first positioning module and the second positioning module are enabled to respectively generate plural wearable device position data and plural portable electronic device position data within a predetermined time period, and the second processing module calculates a displacement of the portable electronic device according to the plural wearable device position data and the plural portable electronic device position data and determines whether a warning mode is enabled according to the displacement.

Abstract
An anti-theft system and an operating method are provided. The anti-theft system includes a wearable device and a portable electronic device. The wearable device includes a first wireless module and a first processing module. The portable electronic device includes a second wireless module, a second processing module and a positioning module. The first wireless module and the second wireless module are in a wireless connection with each other. The second wireless module detects a received signal strength indicator value of the wireless connection. If the received signal strength indicator value is lower than a predetermined signal strength value, the positioning module is enabled to generate plural position data within a predetermined time period. Moreover, the second processing module calculates a displacement of the portable electronic device according to the plural position data and determines whether a warning mode is enabled according to the displacement.
