Password security has been used by people for thousands of years and now pervades the computer-based world. Last year, a team of researchers designed a method of user authentication that employs unique mouse-click rhythms to verify a user’s identity and protect computer systems from unauthorised access.
The team studied the click timing of participants in order to test whether click-rhythms could be used either in conjunction with passwords or to replace them.
After participants practiced designated click-rhythms, their accuracy levels were recorded along with impostor click patterns, and statistical analyses were conducted.
The team found that the accuracy rates of their system were high enough to detect unauthorised access attempts but permitted access to legitimate access attempts. Satisfied with the robustness of the novel security measure, the researchers concluded the method could feasibly be used to strengthen authentication measures for computer-based access security.
For greater efficacy, the researchers noted that personalised click-rhythms should be used. Future research is intended for the refinement of this method and may incorporate the pressure imposed by touch-screen users for greater security.
