Abstract

The Biometrics++ research group explores novel interfaces based on behavioral biometric data. Today, sensors in our personal devices as well as in our environment enable a detailed analysis of user behavior and the use of this knowledge in various application areas. These include secure and user-friendly authentication as well as adaptive user interfaces. The research group lays the conceptual and technical foundations and investigates the user's perspective on such novel interfaces.
