  • Patent number: 10567377
    Abstract: A method and system are provided for multifactor identification of a subject over a network using a rich credential, with selective disclosure of attributes and selective presentation of verification factors. A credential presentation application negotiates with a verifying server to agree on attributes to be disclosed and verification factors to be presented, and removes unneeded attributes and verification data from the rich credential by pruning subtrees from a typed hash tree without invalidating a signature that covers the root label of the tree. The credential presentation application proves knowledge of a private key, and as agreed upon may prove knowledge of a password and may arrange for biometric presentation applications to present one or more biometric samples to the verifier, which performs presentation attack detection and verifies the samples against verification data in the rich credential.
