Abstract
A method in accordance with the present invention is used to organize minutiae and other identifying characteristics of a patterned object to verify a user. In one embodiment, the method includes matching minutiae points of the patterned object in one more sets with minutiae points of the patterned object in a candidate set. The method also includes adjusting a confidence value of each minutia point in the one or more sets based on results of the matching. The method also includes organizing the one or more sets based on the confidence values, such as by ordering the minutiae in the one or more sets based on the confidence values, or by deleting from the one or more sets any identifying characteristics with a confidence value below a threshold.
