Study Determines User Biometric Authentication Preferences

University of Washington researchers conducted a survey of user authentication preferences to determine why the adoption of biometric systems is lagging. They found passwords remain the most commonly used identification method despite the advent of various biometric-based authentication systems that promise to be more secure. For biometric authentication to be accepted by users, it needs to be “efficient and accurate, but also something that people trust, accept and don’t get frustrated with,” stated Cecilia Aragon, associate professor of human centered design at the university. To gather this information, they developed a system that looks like an ATM, but which uses eye-tracking technology as well as a PIN for security. The system was tested by individuals who were asked to make a simulated ATM withdrawal. They found speed, accuracy and choice of error messages were all important in the success of an eye-tracking system. They say most existing biometric systems do not incorporate user experience in their design. The Washington researchers collaborated with Oleg Komogortsev at Texas State University on the system and plan to develop a version that could work in a desktop computer system. The work was presented at the International Association for Pattern Recognition’s International Conference on Biometrics in June.
