The Design And Implementation Of Mobile Anti-Lost System On Android

With the continuous development of science and technology, the traditional phone can not meet the needs of people. Android phone is very popular for people because it has powerful features and low price. But the text messages, contacts, bank card password, QQ chat history and other privacy data is easy to be no intention to see or intention to steal. After the phone is stolen, not only these privacy leaks, can also lead to the relatives and friends deceived, and have a significant impact on people’s work and life.To solve the problem, this paper propose the Mobile Anti-Lost System On Android to ptotect user’s privacy. First introduce the research background, research status, objectives and significance of the study. Then list the related technologies used in the system development, divide the entire system into privacy protection module, instant messaging module, mobile anti-lost module and face recognition module according software engineering. On this basis, start detailed design of each module, and finally introduce the system architecture, implement of each module and testing and analysis of the entire system.In the system, the privacy protection module add lock on the programs which contain privacy according user’s setting, when people open the program, need to enter the unlock password. The instant messaging module provide communication service between mobile and web based on XMPP. The mobile anti-lost module is the core of the system, provide security setting and stolen reminder function, so user can use Web browser and safe number mobile to remote control the stolen phone to delete data, GPS positioning, play alert sound, lock the phone and do other operations, execution results will be returned back. When phone is locked, it can not work well, we need input the password to unlock, or use face recognition to unlock. The face recognition module recognize the user is mobile owner or not, and the determine to lift the locked mobile.Finally, through test, the system can run normally on any Android2.1phone, all functions are meet the needs of analysis requirements, have certain research value and applicant space, and will be a reference for other similar development work.
