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.
