The two federal agencies said they will join Liberty to consider ways of centralising their troves of electronic information with a common authentication system. The GSA said it will explore of ways to implement authentication technology across the federal government's Web sites as part of the Bush administration's 24-step eGovernment initiative. The administration hopes for a common authorisation and voucher system by June.
The Defense Department said it is interested in creating a common authentication system for its automated power, personnel, training and financial databases.
Liberty was launched in 2001 by Sun Microsystems as a way to thwart Microsoft's own authentication system, called Passport. Like Passport, Liberty technology is meant to manage computer users' multiple online identities and information using a single sign-on technology. Its members include Visa International, United Airlines, AOL Time Warner, Fidelity Investments and Vodafone.
Its technology is based on the Security Assertion Markup Language, which enables single sign-on functions and user registration.
An initial version of Liberty was released last July by Sun and its allies. The first version included technology to handle username and password registration; the next version is set to allow information such as credit card numbers to be exchanged as well.
Sun in January began releasing software products that use Liberty.
