Abstract: Embodiments include methods, systems and computer readable storage medium for privacy-enhanced biometric access enrollment. The method includes receiving, by a processor, a biometric signing request (BSR) associated with a request for access rights from a user, wherein the BSR comprises hashed biometric data. The method further includes generating, by the processor, a first biometric signature using at least a portion of the BSR. The method further includes generating, by the processor, a second biometric signature based on at least a portion of the BSR. The method further includes generating, by the processor, an authorization token based on at least the first biometric signature and the second biometric signature. The method further includes sending, by the processor, the authorization token to one or more access control entities or a user computing device for conveyance to the one or more access control entities for authentication.
