When a user enters a personal identification number (PIN) into an automated teller machine or a point of sale terminal, there is a risk of some one watching from behind, trying to guess the PIN code. Such shoulder-surfing is a major security threat. In order to overcome this problem different PIN entry methods have been suggested. In this regard, gaze interaction methods are receiving attention in recent years, owing to the lowering cost of eye tracking technology. In this paper, we present SafetyPIN - an eye tracking based PIN entry system - which is aimed at making the PIN entry more secure with the help of an eye tracking device. We discuss the implementation and the initial evaluation of this system.
