CardSpace, formerly known as InfoCard, is Microsoft's push to create a unified and interoperable online identity and is included as part of the .Net Framework 3.0.
Cameron said the company has spent more time helping enterprise companies with the "identity problem" than consumers, and said the future of consumer identity will not be a single identity used online across every context, but multiple identities used "at the right point in the day". More importantly, Web sites will use the system because users will like it - big sites will be able to provision hundreds of millions of CardSpace-enabled accounts at the flick of a switch.
"Once you accept using multiple identities, the question becomes how can that be organized from a user's point of view - what CardSpace does is use the right one at the right point," Cameron said.
"Identity doesn't work in a silo, so Microsoft can use this in an interconnected world to create a digital economy.
"CardSpace gives users a way to organize their relationships, so it is not like this is an alternative to two-factor ID but a way of making two-factor an experience consistent to the user.
"In the past every implementation of multifactor or advanced identity technologies was different and there was no synergy or application development model which meant architects would have to bet on one particular technology so everything stayed single purpose. CardSpace provides a single application interface for all different identity technologies."
Robert Goldberg, KPMG partner of risk advisory, said Microsoft's CardSpace is less about implementing technology than providing a tool that implements a process people can trust.
Goldberg said the goal is to have control over managing the risk of online transactions based on the level of credentials required.
"CardSpace is attempting to manage risk associated with a new direction of online trading and the newer generation of computer users is going to continue to drive innovation and adoption of processes perhaps our generation didn't even want to accept."
"I think the difference between CardSpace and, say, Active Directory is user control."
