Because now people's busy work, the lost mobile phone also seems mon thing. And bring the most disturbing isa private data loss and insecurity hidden trouble. Based on the above reasons, this paper introduces the design of a mobile phone anti-theft tracking software. This software uses Android system broadcast mechanism, when the mobile phone users to open anti-theft tracking function, the program will monitor the background mobile phone boot, signal condition, send and receive text messages and a change of location, through the monitoring mobile phone user SIM card IMSI code changes to determine mobile phone safety state, monitor and intercepts a secure message content, realize the illegal user the mobile phone number to the legitimate user preset safety numbers to send special message to inform the user of mobile phone function, current status and location information, and through SMS security control of stolen mobile phone lock screen, the destruction of privacy data, send alarm sound and other functions. pleted the design of the software testing, allof its functions are perfect, played a real mobile phone anti-theft tracking function .
