Best Paper at ASSETS 2012

CSE Ph.D. students Shiri Azenkot and Kyle Rector, along with CSE professor Richard Ladner and iSchool (and CSE adjuct) professor Jake Wobbrock won the ASSETS 2012 Best Paper Award at the 14th International ACM SIGACCESS Conference on Computers and Accessibility for their paper “PassChords:  Secure multi-touch authentication for blind people.”

The paper presents a new non-visual technique, PassChords, for user authentication on a touch screen using mult-finger taps, rather than entering a traditional PIN on a virtual keypad.   In a study with 13 blind participants, PassChords was 3 times faster for entering a PIN than using a traditional PIN keypad with a screen reader.  The PIN strength, measured in empirical entropy, was about the same for both methods.

Congratulations to Shiri, Kyle, Richard, and Jake!
