Patent attributes
Methods and systems described in this disclosure electronically notarize a document. The system can receive biometric information from a user, extract characteristics from the biometric information, and compare the characteristics of the biometric information with previously stored characteristics of the user's biometric information. When the characteristics of the biometric information match the previously stored characteristics to a threshold, the system can create an identity of the user using the characteristics of the biometric information. The system can send a document to the user for cryptographic signature and receive an indication that the document has been signed. The cryptographic signature can be generated with a digest of the document, the identity, and a cryptographic key associated with the user. The system can inspect the digest of the document, the cryptographic key, and the identity associated with the document to verify authenticity of the document and the identity of the user.
