User Authentication based on Personal Image Experiences

Building upon the concept of collective computing [1], which combines cloud, crowd and shroud technologies, we propose a further application domain for the fourth generation of computing: Usable Security. Combining the three constituent technologies enables novel, stronger and personalized authentication mechanisms. In particular, we combine implicit memory of people (the crowd), obtained from wearable camera devices (the shroud) and supported by edge and cloud facility (the cloud) in order to generate image-based authentication challenges which are transient and personalized.
