AppShell: Making Data Protection Practical for Lost or Stolen Android Devices

Abstract— In this android application is based on application manager to manage the sensitive private application like (Facebook, what Sapp, twitter, etc.,). This application is a collection of applications for manage the security and privacy of that sensitive application. This application has one password to sign all the application, after sign out from this application then other signed application automatically logout from the network. We use touch screen based password to access this application. Graphical passwords that allow a user to unlock a smart-phone’s screen are one of the Android operating system’s features and many users prefer them instead of traditional text based codes. A variety of attacks has been proposed against this mechanism, of which notable are methods that recover the lock patterns using the oily residues left on screens when people move their fingers to reproduce the unlock code. A pilot study on user habits when set-ting a pattern lock and on their perceptions regarding what constitutes a secure pattern. We use our survey’s results to establish a scheme, which combines a behaviour-based at- tack and a physical attack on graphical lock screen methods, aiming to reduce the search space of possible combinations forming a pattern, to make it partially or fully retrievable. < final year projects >
