Abstract

User identification is undoubtedly important in cyber world. Traditionally, services use login name and password to verify a user. With the rising services of cloud and ubiquitous computing, it becomes a burden for users to memorize all their login name and password pairs for each service they need. Although the advance of new technologies brings us new authentication channels, the purpose of these technologies are for the service provider to be convinced the claimer is really who he or she claims. Few of them have ever concerned about user's anonymity. In this paper, a novel credential based user-centric identification management based on the federated model is proposed. It satisfies the essential of user-centric and ubiquitous computing. Besides, the method keeps the user-centric consideration about anonymity. It supports all the anonymous, pseudonymous, and veronymous identity for user with single-sign-on. © Springer Science+Business Media Dortdrecht 2012.
