Distributed Identity for Secure Service Interaction

People rely on physical identities and computers to access today´s numerous services. It requires having various identity cards and typing of a good number of usernames and passwords daily to prove one´s identity to the remote services. These create inconvenience in use and significant security vulnerability. In this paper, we present a concept of digital identity and thereby accessing services to solve this problem. It uses the mobile phone as identifier to one´s digital identity. An individual is expected to exercise the similar real world roles in digital world through the proposed identity mechanism. Our goal is to develop a system that is both secure and usable.
