Method of multiple algorithm processing of biometric data

摘要

A method performs processing of biometric information to create multiple templates. This allows biometric systems to be flexible and interact with a plurality of vendors' technologies. Specifically, a biometric sample is captured from a sensor and transmitted to a processing component. The biometric sample is then processed by a first algorithm to yield a biometric template and the template is stored and associated with a record identifier. The biometric sample is also processed by a second algorithm to yield a second template. The second template is stored and associated with the record identifier.

1. A method for processing biometric information, comprising the steps of:
capturing a first biometric sample of a live subject from a single device; transmitting the first biometric sample from the device to a processing component; processing the first biometric sample by a first vendor's template generation algorithm to yield a first reference template; associating the first reference template with a record identifier; processing the first biometric sample by a second vendor's template generation algorithm to yield a second reference template; associating the second reference template with the record identifier; and processing a subsequent biometric sample for verification of the live subject by a template generation algorithm to create a match template, wherein the template generation algorithm may be the first vendor's template generation algorithm, the second vendor's template generation algorithm, or a different template generation algorithm; performing, by a computer, a comparison between the match template and of the first reference templates or the second reference template; determining, using the computer, a degree of similarity based on the comparison; and authenticating the live subject based on the degree of similarity.
