There is a need for other mechanisms to be investigated. This paper explores a mechanism for web-based authentication which does not require any expensive hardware or extra software. Two experiments were conducted using a combination of sound and images to authenticate web site users ? exploiting users? associative memory strengths. The results and findings are presented, and conclusions drawn. </ABSTRACT></RECORD></RECORDS></XML>
