Systems and methods for authenticating a user of a biometric sensor
A novel system, device and method of validation is provided for sensing a biometric such as a fingerprint, where biometric data corresponding to the biometric entity such as a fingerprint is then transmitted to a host configured to perform a plurality of authentication processes to authenticate the biometric data. At least one of the plurality of authentication steps is then validated. Alternatively, a portion of the biometric data may be retained, where biometric data corresponding to the biometric is then transmitted to a host configured to perform a plurality of authentication steps to authenticate the biometric data. At least one of the plurality of authentication steps is then validated.
1. A system for authentication, the system comprising:
a first processor;
a second processor; and
a biometric sensor configured to sense a biometric of a user,
wherein the first processor is configured to perform at least one match function between an enrollment template and an extracted template to generate a set of match parameters, wherein the extracted template is based on the biometric sensed by the biometric sensor, and
wherein the second processor is configured to receive the set of match parameters from the first processor and perform at least a portion of a verification process using the set of match parameters.
2. The system of claim 1 , wherein the set of match parameters comprises at least one of a rotation, a translation, and a set of matching minutiae.
3. The system of claim 1 , wherein the set of match parameters comprises a rotation and a translation.
4. The system of claim 1 , wherein the first processor is further configured to perform a template extraction function to generate the extracted template prior to performing the at least one match function.
5. The system of claim 1 , wherein the first processor is further configured to perform an image reconstruction function to generate a standardized biometric image prior to performing the at least one match function.
6. The system of claim 1 , wherein the second processor is further configured to perform the at least a portion of the verification process using the enrollment template.
7. The system of claim 1 , wherein the first processor is a host processor and the second processor is a dedicated processor.
8. The system of claim 1 , wherein the second processor is further configured to release credentials after performing the at least a portion of the verification process to identify a match.
9. A non-transitory machine readable medium comprising one or more sets of instructions for authentication in a system, the system comprising a first processor, a second processor, and a biometric sensor, wherein the biometric sensor is configured to sense a biometric of a user, and wherein execution of the one or more sets of instructions causes the system to:
at the first processor, perform at least one match function between an enrollment template and an extracted template to generate a set of match parameters, wherein the extracted template is based on the biometric sensed by the biometric sensor, and
at the second processor, receive the set of match parameters from the first processor and perform at least a portion of a verification process using the set of match parameters.
10. The non-transitory machine readable medium of claim 9 , wherein the set of match parameters comprises a rotation and a translation.
11. The non-transitory machine readable medium of claim 9 , wherein execution of the one or more sets of instructions further causes the system to:
at the first processor, perform a template extraction function to generate the extracted template prior to performing the at least one match function.
12. The non-transitory machine readable medium of claim 9 , wherein execution of the one or more sets of instructions further causes the system to:
at the first processor, perform an image reconstruction function to generate a standardized biometric image prior to performing the at least one match function.
13. The non-transitory machine readable medium of claim 9 , wherein execution of the one or more sets of instructions causes the system to perform the at least a portion of the verification process using the enrollment template.
14. The non-transitory machine readable medium of claim 9 , wherein the first processor is a host processor and the second processor is a dedicated processor.
15. The non-transitory machine readable medium of claim 9 , wherein execution of the one or more sets of instructions further causes the system to:
at the second processor, release credentials after performing the at least a portion of the verification process to identify a match.
16. A method for authentication in a system, the system comprising a first processor, a second processor, and a biometric sensor, wherein the biometric sensor is configured to sense a biometric of a user, the method comprising:
at the first processor, performing at least one match function between an enrollment template and an extracted template to generate a set of match parameters, wherein the extracted template is based on the biometric sensed by the biometric sensor, and
at the second processor, receiving the set of match parameters from the first processor and performing at least a portion of a verification process using the set of match parameters.
17. The method of claim 16 , wherein the set of match parameters comprises a rotation and a translation.
18. The method of claim 16 , wherein the at least a portion of the verification process is performed using the enrollment template.
19. The method of claim 16 , wherein the first processor is a host processor and the second processor is a dedicated processor.
20. The method of claim 16 , further comprising:
at the second processor, releasing credentials after performing the at least a portion of the verification process to identify a match.
