Shuffled Illusion PIN Framework to Prevent Shoulder – Surfing

Shoulder surfing is a kind of technique applied to sneak the personal data like passwords and some confidential data of the user. For this type of attacks there is no need of any kind of technical knowledge but just a keen observation towards the user performance is necessary. However, secret gadgets made these shoulder surfing easy for the attackers like cc cams. To overcome these attacks some authentication schemes are proposed- Illusion pin that works on digital display. It applies the method of hybrid pictures with 2 keypads blended one keypad with another, it is designed by using the human visibility and quotes the least distance at which an attacker is incapable to understand the buttons. We developed an innovative shuffling algorithm for shuffling the keys for every single pin entry. Using this Shuffling algorithm, we create a new pattern of the keypad for every exclusive entry of the pin. Through this technique the attacker is unable to track the pin even if he remembers the spatial arrangement of the digits in a keypad. To provide more security we are adding one-time password generating (OTP) technique.
