11. The system of claim 9 , wherein, the validating further includes:

receiving a match parameter from the host computing device; and

comparing the enrollment template with the extracted template, using the match parameter.

12. A method, comprising:

sensing, at a sensor, a biometric image of a biometric of a user to obtain biometric data;

retaining, at the sensor, a second portion and not all of the biometric data;

transmitting the biometric data corresponding to the biometric image to a host computing device separate from the sensor, wherein the host computing device performs a plurality of authentication steps to authenticate the user as being identified by the biometric data, wherein the plurality of authentication steps comprises producing a first result at the host computing device by comparing a template extracted by the host computing device from a first portion of the biometric data to a stored template stored by the host computing device; and

validating, at the sensor, the at least one and not all of the plurality of authentication steps utilizing authentication information received from the host computing device relating to results of the host computing device performing the at least one of the plurality of authentication steps by comparing a template extracted by the sensor from the second portion of the biometric data retained by the sensor and corresponding to the first portion utilized by the host computing device, to produce a second result, and comparing, by the sensor, the first result with the second result.

13. The method of claim 12 , wherein the portion of the biometric data is randomly selected.

14. The method of claim 12 , wherein the portion of the biometric data is of a resolution lower than that of the biometric data transmitted to the host computing device.

15. The method of claim 12 , wherein the validating includes:

receiving, at the sensor, the biometric image; and

verifying, at the sensor, a similarity between the second portion of the biometric data and a corresponding portion of the biometric image.

16. The method of claim 12 , wherein the plurality of authentication steps further includes extracting a swipe template from the biometric image.

17. The method of claim 16 , wherein the swipe template includes biometric minutiae.

18. The method of claim 17 , wherein the validating further includes:

receiving the swipe template; and

verifying a similarity between biometric minutiae existing in the second portion of the biometric data and the biometric minutiae of the swipe template.

19. The method of claim 18 , wherein the plurality of authentication steps further includes matching the swipe template with an enrollment template stored at the sensor.

20. A non-transitory machine readable medium storing instructions that, when executed by a computing device, cause the computing device to perform a method, the method comprising:

sensing, at a sensor, a biometric image of a biometric of a user to obtain biometric data;

retaining, at the sensor, a second portion and not all of the biometric data;

transmitting the biometric data corresponding to the biometric image to a host computing device separate from the sensor for the host computing device to perform a plurality of authentication steps to authenticate the user as being identified by the biometric data, wherein the plurality of authentication steps comprises producing a first result by the host computing device by comparing a template extracted by the host computing device from a first portion of the biometric data to a stored template stored by the host computing device; and
