PETS Keynote: Goodbye Passwords, Hello Biometrics – Do We Understand the Privacy Implications?

Prof. M. Angela Sasse

After 2 decades of struggling with passwords, we are finally being offered easy-to-use biometric solutions to authenticate. Whilst most users welcome these, some worry about privacy implications of different biometrics and continuous authentication (systems recognises users without disrupting them). Many biometrics – eye movements being a key example – reveal much more about users than who they are, and some commercial authentication services claim to track up to 400 different characteristics. In this talk, I will review privacy and other concerns people have about this tracking.
