Claim 9:
10. A method comprising:
generating a verifier at a first device by processing a first artifact stored on the first device;
receiving a credential from a second device after the verifier is generated;
updating the first artifact based on a first transactional history between the first device and the second device, wherein the first transactional history is stored on the first device;
updating a second artifact stored on the second device based on a second transactional history between the first device and the second device, wherein the second transactional history is stored on the second device;
generating the credential by processing the second artifact stored on the second device;
determining if a transaction should be authorized based on a comparison between the credential and the verifier, wherein the comparison is performed responsive to a request for the transaction;
transmitting information indicative of the comparison to the second device; and
executing the transaction when the information indicative of the comparison indicates the transaction should be authorized, wherein the first transactional history and the second transactional history being associated with a matching transactional relationship indicates the transaction should be authorized.
