Cheap and Easy PIN Entering Using Eye Gaze
Abstract
PINs are one of the most popular methods to perform simple and fast user authentication.PIN stands for Personal Identification Number, which may have any number of digits or even letters.Nevertheless, 4-digit PIN is the most common and is used for instance in ATMs or cellular phones.The main advantage of the PIN is that it is easy to remember and fast to enter. There are, however,some drawbacks. One of them - addressed in this paper - is a possibility to steal PIN by a techniquecalled `shoulder surfing'. To avoid such problems a novel method of the PIN entering was proposed.Instead of using a numerical keyboard, the PIN may be entered by eye gazes, which is a hands-free,easy and robust technique.
