Managing Identity in the Digital World
Ultimately the solution you implement should best serve your environment. Though the examples used in this paper deal primarily with the username and password methodology for access control, a number of other options exist. SecureID cards, certificates, biometrics and other tokens are all other forms of identification used today. These considerations need to be applied when choosing your solution.

Federated Identity Management
Federated Identity management makes it possible for an authenticated identity to be recognized and take part in personalized services across multiple domains. It avoids pitfalls of centralized storage of personal information, while allowing users to link identity information between different accounts. Users control linking of account management (to an extent) and personalization of services. Federated identity requires two key components: trust and standards [2]. Trust model of Federated Identity management is based on Circle of Trust.

Dos and Dont's of Client Authentication on the Web
Client authentication has been a continuous source of problems on the Web. Although many well-studied techniques exist for authentication, Web sites continue to use extremely weak authentication schemes, especially in non-enterprise environments such as store fronts. These weaknesses often result from careless use of authenticators within Web cookies. Of the twenty-seven sites we investigated, we weakened the client authentication on two systems, gained unauthorized access on eight, and extracted the secret key used to mint authenticators from one.
