Knowledge-Based Authentication: Evaluating and Improving Case for Support – Description of Proposed Research and its Context

Authentication is central to computer security and almost every use of computerised systems. With the explosion of online e-commerce, banking, social web sites and governmental services, the problem of finding secure, usable and efficient authentication systems is more acute than ever. The risks of security failure are obvious, and unusable or inefficient systems additionally risk loss of customers or overly expensive support services managing password recovery.
