Multi-touch authentication on tabletops

Briggs provided the original design input for the most successful of the authentication methods and provided sole psychological input to a multidisciplinary team, throughout and during write up.

This portfolio includes patent (No. GB2476822: Pressure-based Authentication system for multi-touch surfaces - granted April 2012). This invention is an authentication system for a multi-touch surface that uses two finger pressure combinations. The system was found to be both easy to use and also resistant to shoulder surfing. An accompanying peer-reviewed, ten page conference paper, presented at CHI, the leading international HCI conference and published in the ACM Digital Library (total downloads 1,983), describes a set of five novel designs for tabletop authentication systems and presents an evaluation of each of them. This work is one in a series of studies that explore usable and inclusive authentication in different contexts and forms part of a body of work on design issues in authentication and identity management (part-funded by EPSRC grant EP/J005037/1).
