The smartphones have become the basic necessity of life. Users are being authenticated on mobile devices using PINs, password, swipe, etc. However, the existing authentication mechanisms are not resilient against modern security attacks. With the increase of touch devices, gesture-based authentication behaviour becomes more important. This paper analyzes the distinctness of a gesture in a touch base mobile device. Analysis show that specific user has distinct gesture of different fingers. Experimental study reveals that finger accuracy in a gesture-based authentication is increased by an individual's index finger and thumbs. Furthermore, the results show that the accuracy and efficiency of a gesture-based lock depends on the phone's position, portrait mode, left or right-handed user, and single or double hand user style.
