PandaLock: Variable-Pointer Rotary-Password Authentication Technique

The graphical nature of graphical password nearly makes all graphical passwords vulnerable to shoulder attack. Humans want an easy method of authentication and powerful in terms of security. The problem in most techniques however, less vulnerable passwords are complicated, less user-friendly and lastly, login time takes very long. In this paper, a graphical password authentication technique proved to be more resistant to shoulder-surfing and other types of possible attacks have been proposed. PandaLock technique is a hybrid approach, which combines recall based and recognition based approach. Combination-lock interfaces with variable pointers are used to authenticate the users in this proposed system. A Portable handheld device was used to simulate and test the proposed system.
