Bio:
Dr. Ioannis Krontiris is a senior researcher in the group of Mobile Business and Multilateral Security at Goethe University Frankfurt, Germany. Before moving to Frankfurt, he worked as a postdoctoral researcher in the Laboratory for Dependable Distributed Systems in Mannheim University, focusing on security and privacy. He holds a PhD in computer science from Mannheim University, Germany, a master’s degree in Information Networking from Carnegie Mellon University, USA, and a diploma in computer engineering from Technical University of Crete, Greece.
His research focuses on system architectures that incorporate privacy enhancing technologies in real-life applications, not only in the online world but also in the pervasive environment. In particular, at Goethe University Frankfurt he coordinates the EU funded project ABC4Trust, which builds a common, unified architecture of Attribute Based Credential systems, implements and combines their respective features on a common platform and deploys them in actual production pilots .
Minimal disclosure and anonymous credentials
Abstract:
So far credentials such as digitally signed pieces of personal information or other information used to authenticate or identify a user where not designed to respect the users privacy. They invariably reveal the identity of the holder even though the application at hand often needs much less information, for instance only confirmation that the holder is a teenager or is eligible for social benefits. In contrast to that, minimal disclosure and anonymous credentials allow a holder to reveal just the minimal information required by the application, without giving away full identity information. These credentials thus facilitate the implementation of a trustworthy and at the same time privacy-protecting digital society.
