Abstract or Summary:
Passwords and pin numbers are ubiquitous even though they are basically flawed and cause problems for users due to memory workload. 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 evaluations 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.
