Many web applications provide secret questions, to reset the account password when a users login fails. Most secret questions are blank fillings and are created based on the long-term knowledge of a users personal history that may not change over months/years. Today's prevalence of smartphone has granted us new opportunities to observe and understand how the personal data collected by and audio are sent as SMS to the alternative number and mail id of the user. If unauthorized tries to access the secret apps then, the system will query the user with four random questions (two from normal &two from user runtime).If not authorized, then GPS, camera, voice recorder is initiated and sent to the original user for tracking. This application helps user to identify the lost or stolen mobile by tracking mechanism smartphone sensors and apps can help create, personalize secret questions without violating the user’s privacy concerns.In Existing system, a set of secret questions was created based on the user’s personal history such as “What is your place of birth?” which can be easily identified .It may lead to poor security and reliability. A prototype is developed on Android smartphone and evaluates security of the secret questions.The proposed system, to reveal the secret questions related to calendar, last charged time, photo taken, contacts, call logs, SMS logs and app usage history which are memorable for users and are highly robust to attacks.In Modification of the project, this application will frame a set of standard questions along with the user runtime. If a mobile is stolen or lost, they either change the SIM card or retain the same and try to access the apps. If SIM card is changed then automatically GPS, Camera, Voice recorder are initiated, So that location
