Hash visualization in user authentication
Rachna Dhamija · 2000
Although research in security has made tremendous progress over the past few years, most security systems still suffer by failing to account for human factors. People are slow and unreliable at processing long and meaningless strings, yet many security applications depend on this skill. For example, a major problem in user authentication is that people have difficulties in choosing and memorizing secure passwords. In this paper, we have investigated how the usability and security of user authentication systems can be improved by replacing text strings with structured images.
