Systems and methods for generating a derived biometric template

摘要

Systems and methods for generating a derived biometric template are provided. A biometric sample of a user is determined. A base biometric template includes a plurality of features extracted from the biometric sample. A degree of rotation is determined, and a derived biometric template is generated using the degree of rotation.

1. A method for generating a biometric template, the method comprising:
during an enrollment phase:
determining, by a mobile device, a biometric sample of a user;determining a base biometric template based on the biometric sample, wherein the base biometric template includes a plurality of features extracted from the biometric sample;determining a directional tolerance associated with the base biometric template;determining a degree of rotation based on the directional tolerance;generating a derived biometric template using the degree of rotation; andstoring the base biometric template and the derived biometric template for comparison, during a recognition phase, to a recognition biometric sample of the user,wherein the base biometric template is to match the recognition biometric sample in a first orientation, and wherein the derived biometric template is to match the recognition biometric sample in a second orientation.
