This paper describes a novel approach to authenticate entry to a system using tactile feedback. The user is required to remember a sequence of pre-selected pin patterns. A study has been undertaken to determine the feasibility of the tactile authentication mechanism, through a comparison with a graphical scheme. Findings from a within-subjects study have revealed that both tactile and graphical authentication sequences could be entered at specific points over the course of a five month period. While graphical sequences could be entered on average 28.5 seconds faster than tactile sequences, participants believed the tactile mechanism offered greater levels of security from observers. As pins are presented underneath the fingertips, they are concealed from the view of third parties. As tactile sensations are difficult to describe, it is less likely that they will be disclosed to others, thereby reducing the chances of unauthorized access.
