Unlike other applications that try to prevent intruders from accessing the phone's content, "Who Touched my Phone" doesn't block any content but captures the snooping event without the intruder's knowledge; Moreover, Tal Shumski the CTO of App & Joy says "we believe that you cannot protect all of your phone's information completely, all of the time; Therefore, we find it more important to secretly capture and inform you whenever there was an attempt to snoop through your phone".
How does it work you wonder? The user arms the application and locks the screen. When the phone is unlocked, the intruder will see an innocent screen presenting YouTube's best videos, and in the meantime they are captured without their knowledge with multiple pictures, the time of action, and location. Afterwards, when the user opens the application, and disarms the phone using a unique gesture, a screen with all captured intruders will be presented. For each intruder the user will see when and where it occurred, and the pictures of the intruder. Taping on one of the intruders pictures will present a screen with the intruder's photo gallery (up to 5 pictures) and information about the event.
