Abstract

In current ATM process there is lot of ATM fraud Malicious money transaction and theft are happens by means of lack of privacy protection in current scheme. We address the problem of shoulder-surfing attacks on authentication schemes by proposing Illusion PIN (IPIN), a PIN-based authentication method that operates on touch screen devices. IPIN uses the technique of hybrid images to blend two keypads with different digit orderings in such a way, that the user who is close to the device is seeing one keypad to enter her PIN, while the attacker who is looking at the device from a bigger distance is seeing only the other keypad. The users keypad is shuffled in every authentication attempt since the attacker may memorize the spatial arrangement of the pressed digits. To reason about the security of Illusion PIN, we developed an algorithm which is based on human visual perception and estimates the minimum distance from which an observer is unable to interpret the keypad of the user. In addition, we estimated the minimum distance from which a camera is unable to capture the visual information from the keypad of the user. Based on our analysis, it seems practically almost impossible for a surveillance camera to capture the PIN of a Smartphone user when IPIN is in use. In current scheme we also implement the OTP authentication mechanism. This will enhance more security which is attached with virtual Keyboard of ATM machine. So we proposed the concept of ATM protection including shuffling keyboard with OTP authentication. V. Saravanan | M. Sathishkumar | M.
