The Secure Haptic Keypad: A Tactile Password System
Andrea Bianchi, Korean Advanced Institute of Science and Technology, Korea
Ian Oakley, Universidade da Madeira, Portugal
Dong-Soo Kwon, Korean Advanced Institute of Science and Technology, Korea

This paper proposes a novel design for shoulder-surfing resistant password input interface and method based on tactile cues (haptic password).

Multi-Touch Authentication on Tabletops
David Kim, Newcastle University, United Kingdom
Paul Dunphy, Newcastle University, United Kingdom
Pam Briggs, Northumbria University, United Kingdom
Jonathan Hook, Newcastle University, United Kingdom
John Nicholson, Newcastle University, United Kingdom
James Nicholson, Northumbria University, United Kingdom
Patrick Olivier, Newcastle University, United Kingdom

Presents an initial exploration of the design space for observation resistant authentication for multi-touch tabletops. Contributes towards privacy respectful input of credentials in co-located collaborative contexts.

ColorPIN - Securing PIN entry through indirect input
Alexander De Luca, University of Munich, Germany
Katja Hertzschuch, University of Munich, Germany
Heinrich Hussmann, University of Munich, Germany

Presents an authentication system based on indirect input that is resistant to shoulder surfing and camera attacks. A formal evaluation highlights increased security and performance issues due to raised complexity.

Shoulder-Surfing Resistance with Eye-Gaze Entry in Click-Based Graphical Passwords
Alain Forget, Carleton University, Canada
Sonia Chiasson, Carleton University, Canada
Robert Biddle, Carleton University, Canada

Cued Gaze-Points is an eye gaze-based graphical password system resistant to shoulder-surfing. A user study showed potential usability and highlighted limits in gaze precision.

Visual vs. Compact: A Comparison of Privacy Policy Interfaces
Heather Richter Lipford, University of North Carolina at Charlotte, USA
Jason Watson, University of North Carolina at Charlotte, USA
Michael Whitney, University of North Carolina at Charlotte, USA
Katherine Froiland, University of Minnesota, USA
Robert W. Reeder, Microsoft, USA

A comparison study of two prototype interfaces for privacy policies finds that users perform similarly with each, but have a clear preference for one or the other.
