A Smart Phone Anti-theft Solution Based on Locking Card of Mobile Phone

This paper analyzes the security measures for current smart phone. A smart phone anti-theft solution based on locking SIM card of mobile phone is proposed. The solution proposed in this work mainly consists of software components, according to which hardware needs to be selected. It also gives the overall structure of mobile phone anti-theft system, the main software functional blocks and the implementation flow chart of each module. The functions of locking and unlocking of mobile and SIM card, anti-theft and short messaging service control are realized by adding locking SIM card setting module, locking SIM card control module and anti-theft processing module. By the use of software algorithm, users may find stolen mobile phone and protect critical information. To some extent it can reduce the losses caused by the stolen phone.
