Abstract

A study sponsored by the US National Institute of Standards last year found that regular computer users suffer from Authentication Fatigue, and re-organize their work to reduce the burden caused by explicit authentication (where they user is challenged to provide credentials).

The authors suggested that implicit authentication (where the system recognises users without disrupting them) would be the way forward to reduce the workload. Biometrics will play a key role in authenticating users in a low-effort way, with pressure on touchscreens and eye movements set to play a leading role. Many of these biometrics – eye movements being a key example – reveal much more about users than who they are, and some commercial products claim to track up to 400 different characteristics. Does convenience mean giving up privacy and informational self-determination, or can we have both?
