Graphical password authentication using hybrid pin keypad

The important problem in information security is user authentication. There are many authentication techniques are textual, graphical or biometric passwords etc. The text based password is easily guessed by the attacker over to nearby shoulder; attackers observed directly or watch some external devices. The text based password authentication methods are not enough for shoulder surfing attacks. The graphical based password authentication is best, because it is more secure and it provides better resistance to shoulder surfing attacks. The traditional two-factor authentication mechanisms aren’t applicable to online social networks, because the physical token or biometric information cannot be simply accustomed login to users’ profiles. The simplest alternate solution for the single factor password based authentication process with additional identification elements, such as OTP( One Time Password) codes, generated by the user’s own device (e.g. the smart phone) or received via SMS. The proposed system Hybrid PIN Keypad method is used to reduce the shoulder-surfing attacks. The Hybrid PIN Keypad techniques applied for Net Banking application. This technique is used to protect from shoulder surfing attacks.
