Tactile, Auditory and Graphical Authentication for Desktop and Mobile Interfaces

Overview

Research suggests that human limitations are rarely considered in the design of knowledge-based authentication systems. In an attempt to foster entry to a system, individuals tend to choose passwords which are easy to recall. However, inappropriate selection can compromise data security. In order to restore the balance between security and memorability, we have proposed tactile based solutions. Our studies have shown that 'tactile passwords' (composed of four stimuli) can be recognized with strong levels of accuracy over a long term period. Studies examining authentication for individuals who are blind have been conducted. Research has also focused on ways in which abstract sounds can be used for authentication.

 

More recent work is focusing on ways that we can design tactile and gestural authentication solutions for mobile usage (H4Plock), multi-factor authentication, and issues associated with selecting patterns for unlock screens. The research is funded through the Office of Naval Research, in collaboration with Dr. Adam J. Aviv at USNA.
