In the modern world everyone using the ATM’S (automated teller machines), digital door locking systems, debit card terminals and point of sales terminals (POS). PIN security is compromised in public places easily. User normally uses same PIN for multiple applications. The Direct PIN entries are highly affected to shoulder-surfing attacks can effectively capture user’s PIN entry number by concealed cameras. Indirect PIN entry method proposed to achieve usability and security. Here, SteganoPIN is indirect practical PIN entry method. The human-machine interface between two numerical keypads, a user can generate a one-time PIN can safely enter by the plain view of attackers. The user basic interface of SteganoPIN is standard keypad with regular layout and other is a small separate keypad is challenge keypad with random key layout. The challenging keypad is vary according to the IR based Proximity Sensor. To derive fresh OTP a user must use this challenging keypad. The user first locates PIN in random key layout and subsequently maps the key locations into the standard keypad for OTP derivation. For each attempt of PIN, capture the user’s picture using camera and send it to the registered authorized person’s mail that person can recognize the user who are trying to attempt their account.
