System, method and program product for recording creation of a cancelable biometric reference template in a biometric event journal record

摘要

A system, method and program product for recording the creation of a cancelable biometric reference template in a biometric event journal record. The method includes providing a base biometric reference template having a unique base reference template identifier that uniquely identifies base biometric data collected for an individual, applying a data transform function having a first function key value to the base biometric reference template to create one cancelable biometric reference template and recording the one cancelable biometric reference template in a biometric event journal record. The method further includes creating additional cancelable biometric reference templates using different function key values of the data transform function. The method further includes encrypting the data transform function and the function key value applied to the base biometric reference template. The method further includes signing the cancelable biometric reference template and signing the biometric event journal with a digital signature.
