Selling Your Self:Examining Values in Identity 2.0

September 30, 2006

Network identity refers to the global set of attributes that are contained in an individual's various accounts with different service providers. These attributes include such information as name, phone numbers, social security numbers, addresses, credit records, and payment information.

For individuals, network identity is the sum of their financial, medical, and personal data—which must be carefully protected. For businesses, network identity management creates the ability to have greater knowledge of their customers and constituents, and to interact with them in ways that bring greater value to both parties.
