Patent ID: 8893242

Claim:
A method comprising: receiving, by a service consumer from an identification authority, a non-portable identity document associated with the service consumer, the identity document including signed assertions corresponding to independently verifiable data of the service consumer, the independently verifiable data including an IP address of the service consumer, the identity document being bound to the IP address of the service consumer, and the signed assertions being compatible with a security assertion markup language; generating, by use of a processor of the service consumer, a request for credentials including at least a portion of the content of the identity document, the portion including an assertion corresponding to the IP address; sending the request for credentials from the service consumer to an authentication authority; and based on a match between the IP address corresponding to the assertion included in the sent portion of the content of the identity document and an IP address retrieved by the authentication authority based on the request but independently from the identity document, receiving credentials from the authentication authority by the service consumer; and sending the received credentials along with a request for service from the service consumer to a service provider.
