Biometric electronic signature authenticated key exchange token

The methods and system allow for the generation of a signcrypted biometric electronic signature token using a subsequent biometric sample after an enrollment of a biometric reference value in a biometric system. The signcrypted biometric electronic signature token involves simultaneous encryption and digital signature to protect the confidentiality. The system as described herein provides data integrity, origin authentication, and efficiency by performing encryption and digital signature simultaneously. The process allows a signcrypting party to enroll in a biometric service, sign a piece of data or content using a public key, that may be tied to a trusted anchor certificate authority, and submit a biometric sample. Subsequently, the relying party may validate the information on that piece of data or content to confirm the identity of the signcrypting party.
