Abstract

Systems and methods for tokenless authorization are provided. Obtaining an electronic representation of an initial biometric sampling of a registrant. Applying the initial electronic representation to a first cryptographic function that produces a unique digital identifier (UDI). Obtaining account information constructs corresponding to an account by the registrant with a third party. Generating a unique secure identification number (SIN) using the UDI and the account information constructs. Storing a unique link from the UDI to the account information constructs. Receiving a request for service and an electronic representation of a second biometric sampling. Forming the UDI by applying the second electronic representation to the first cryptographic function. Verifying the UDI corresponds to the stored UDI to reconstruct the unique SIN from the UDI and using this unique SIN to retrieve the account information constructs through the indexed data structure. Transmitting the request and the unique SIN to the third party.
