Abstract

Web-based identity management systems (IdMS), a new and innovative information technology (IT) artefact, involve the integration of emerging technologies and business processes to create identity-centric approaches for the management of users, their attributes, authentication factors and security privileges across the Internet within multiple websites. With the growth of online identities on the Internet, IdMS enable the use of the same user data, managed identifiers and authentication credentials across multiple websites, reducing the number of identifiers (e.g. passwords) and profiles with which a user has to deal. As digital identity becomes more and more important in the online world, the emergence of IdMS has brought about primary changes to different online contexts. The trajectory of the IdMS migration can be understood in relation to the proprietary system and the openness of the system to exchanging identity information .This study chooses to make the distinction and classification of three types of IdMS models – isolated model, centralized model and decentralized model –because of their differences in architecture and standards and their different impact on security, privacy and usability issues.We develop guidelines for IdMS designers and provides for the employment of more targeted implementation efforts. Also, we discuss some implications and highlight some opportunities for creating and enhancing new IdMS.
