20090288150 | ACCESS CONTROL BY TESTING FOR SHARED KNOWLEDGE - Access to resource(s) intended to be shared with specific groups of individuals is controlled using concise tests of shared knowledge instead of (or in addition) to accounts and access control lists. Users can readily learn the concept and choose questions that will control the access by the desired group with little effort.
