摘要:AbstractPhone lost has been a major problem these days. This case can happened because of the user own fault (he place it in the wrong place and forget it) or because of intentional phone stealing. Seeing many of this missing case we try to develop a system for tracking and securing a missing phone. Android platform is selected because it is one of the best operating system for mobile phone right now and the user growth is very promising. This application will give an extra security when a phone gone missing, as we know we store a lot of sensitive data on our phone. The system work flow is very simple actually, our application will be on standby and monitor command that it received via SMS and it will work in the background so user won’t be get any distraction from this application. Using these commands user can lock his phone, sound the phone alarm, delete his phone data, get his phone data, and get his phone last location. This application have some other feature too, like lock his phone when someone change his phone card and send the new number that attach in his phone to the owner. When system get any request about phone's last position then system will process that request to get phone's latitude and longitude via GPS, after that system will quietly send it to the owner.
