Dongwan Shin, Gail‐Joon Ahn, P. Shenoy · 2004
Surveys and polling data confirm that the Internet is now a prime vehicle for b'USiness, community, and personal interactions.The notion of identity is the important component of this vehicle.When 'USers in teract with services on the Internet, they often tailor the services in some way for their personal use.For example, a user may establish an account with a user name and password and/or set some preferences for what information the user wants displayed and how the user wants it displayed.The network identity of each user is the overall global set of these attributes constituting the vario'US accounts.In this paper, we investigate two well-known federated identity manage ment (FIM) solutions, Microsoft Passport and Lib erty Alliance, attempting to identify information as surance (IA) reqtlirements in FIM.In particular, we foc'US on principal IA requirements for Web Services (WS) which plays an integral role in enriching iden tity management through federation.
