Abstract:

Shoulder-surfing — using direct observation techniques, such as looking over someone’s shoulder, to get passwords, PINs and other sensitive personal information is a problem that has been difficult to overcome. When a user enters information using a keyboard, mouse, touch screen or any traditional input device, a malicious observer may be able to acquire the user’s password credentials. We present EyePassword, a system that mitigates the issues of shoulder surfing via a novel approach to user input. With EyePassword, a user enters sensitive input (password, PIN, etc.) by selecting from an on-screen keyboard using only the orientation of their pupils (i.e. the position of their gaze on screen), making eavesdropping by a malicious observer largely impractical. We present a number of design choices and discuss their effect on usability and security. We conducted user studies to evaluate the speed, accuracy and user acceptance of our approach. Our results demonstrate that gaze-based password entry requires marginal additional time over using a keyboard, error rates are similar to those of using a keyboard and subjects preferred the gaze-based password entry approach over traditional approaches.

Lustige Idee … wir starren auf den Bildschirm, bis das Passwort gefunden ist. Ich stelle mir gerade passende Brute Force Eye-Password Cracker vor … 🙂 Nur darf man dann nicht mehr koksen sonst wird das nichts mit dem Passwort-Fokus.
