Abstract

Authentication in public spaces, such as ATM PIN entry, is inherently susceptible to security attacks based on observation in person or via cameras. This paper briefly introduces the idea of decoupling the authentication process in two separate sub-tasks (the interaction needed for PIN input and its transmission to the terminal), each with different usability and security goals. In order to support this idea, we present two research projects based on multimodal feedback and physical proximity and explain how they fit into this model.
