Abstract
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.
Claims20
A method for generating a biometric template, the method comprising:
- 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;
- and
- generating a derived biometric template using the degree of rotation.
A method for biometric recognition, the method comprising:
- determining, by a mobile device, a degree of rotation associated with a base biometric template, wherein the base biometric template includes a plurality of features extracted from a biometric sample;
- generating a derived biometric template using the degree of rotation;
- associating an action of a plurality of actions in the mobile device with the derived biometric template;
- comparing a recognition biometric sample to a plurality of templates stored in a memory of the mobile device;
- identifying, based on the comparison, a template of the plurality of templates that matches an extracted feature of the recognition biometric sample;
- and
- determining an action of a plurality of actions corresponding to the matching template.
A non-transitory computer-readable medium storing a plurality of instructions to control a data processor, the plurality of instructions comprising instructions that cause the data processor to:
- determine a biometric sample of a user;
- determine a base biometric template, wherein the base biometric template includes a plurality of features extracted from the biometric sample;
- determine a directional tolerance associated with the base biometric template;
- determine a degree of rotation based on the directional tolerance;
- and
- generate a derived biometric template using the degree of rotation.
The non-transitory computer-readable medium of dam 16, wherein the plurality of instructions further comprise instructions that cause the data processor to:
- determine whether to generate additional derived templates;
- and
- generate a second derived template using the degree of rotation.
