ABSTRACT:
An anonymous credential system which requires a user who is asserting a credential to have knowledge of the master key of the user who was originally granted that credential. In order for a user to transfer the ability to assert any one of their credentials to another user, they must also transfer their master key to that same user. The master key, however, provides such unlimited rights to its holder that a user is strongly motivated not to share their master key with anyone else. In this manner, anonymous credentials become non-transferrable because a user cannot transfer a credential without transferring their entire electronic identity.
