Abstract :
Abstract — National and global economic, governmental and
social activities now rely more and more on the Internet.
Online Identity Management (IdM) is a crucial component of
those activities. Today, organisations in both the public and
private sectors vary significantly in their approaches to IdM,
devising their own means for establishing, verifying, storing
and using digital identities over their networks and the
Internet. Thus, the lack of common policies and approaches
to such Federated IdM systems creates privacy, security and
productivity issues in the increasingly interconnected
economies, and hampers the ability of organisations to
provide users with convenient services. This paper presents
the investigation and discussion of challenges faced in
implementing the Federated IdM in the online system. Also,
a trust-based framework is discussed in order to combat these
challenges.
