1. A method for providing an identification reference image of a user, the method comprising:
- determining two or more Image Quality Index (IQI) scores of a biometric identifier of the user based on two or more respective images received from two or more respective imaging devices;
comparing said two or more IQI scores; and
generating an identification reference biometric identifier image for the user with the imaging device of said two or more different imaging devices that produced the image with the highest of said two or more IQI scores.

Abstract
In an enterprise biometric identification/authentication and migration system, a method and apparatus is disclosed for providing an identification reference image of a user by determining two or more Image Quality Index scores of a biometric identifier of the user based on two or more respective images received from two or more respective imaging devices, comparing the scores, and generating an identification reference biometric identifier image for the user with the imaging device that produced the image with the highest score. In some embodiments, the method and apparatus is extended to a plurality of biometric identifiers

8. A method for providing a plurality of identification reference images of a user, the method comprising:
-
determining an Image Quality Index (IQI) score for each of a plurality of biometric identifiers of the user based on a plurality of images of said plurality of biometric identifiers, respectively, received from a first imaging device;
determining an IQI score for each of said plurality of biometric identifiers of the user based on a plurality of images of said plurality of biometric identifiers, respectively, received from a second imaging device;
computing a first average IQI score based on the IQI scores of said plurality of images received from the first imaging device;
computing a second average IQI score based on the IQI scores of said plurality of images received from the second imaging device;
comparing the first and second average IQI scores; and
generating said plurality of identification reference biometric identifier images for the user with the imaging device of said first and second imaging devices that produced the images having a higher average IQI score. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An apparatus for providing an identification reference image for biometric identification and/or authentication of a user, the apparatus comprising:
-
a processor to determine two or more Image Quality Index (IQI) scores of a biometric identifier of the user based on two or more respective images received from two or more respective imaging devices;
to compare the two or more IQI scores; and
to generate an identification reference biometric identifier image for the user with the imaging device of said two or more imaging devices that produced the image having the highest IQI score; and
a memory, associated with the processor, for storing said two or more images received from the two or more imaging devices, said IQI scores, and said identification reference biometric image. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. An apparatus for providing a plurality of identification reference images for biometric identification and/or authentication of a user, the apparatus comprising:
-
a processor to determine a plurality of Image Quality Index (IQI) scores for each of a plurality of biometric identifiers of the user, based on a plurality of images of said plurality of biometric identifiers, respectively, received from each of a plurality of imaging devices;
compute average IQI scores for each said plurality of IQI scores;
compare the average IQI scores for each of said plurality of IQI scores; and
generate said plurality of identification reference biometric identifier images for the user with the imaging device of said plurality of imaging devices that produced the plurality of images having the highest aver age IQI score; and
a memory, associated with the processor, for storing said plurality of images received from each of said plurality of imaging devices, said IQI scores, said average IQI scores; and
said plurality of identification reference biometric images for the user. - View Dependent Claims (24, 25, 26, 27, 28)
