The diagram below depicts the score buckets for our results. We will test each fingerprint scan within the same bucket with the template (the normal finger scan) and record the score and put it into the genuine bucket. Then we will test a template from one bucket with various combination of scans from other buckets (so A.template will be tested with B.template, B.pruned1, B.pruned2, ..., H.template, H.pruned1,...) and the result of this should be put into the impostor bucket.
The histogram below shows an ideal histogram for the results. The curve on the right basically represents the genuine scores, and the curve on the left is the impostor scores. This is an ideal case however, so real results may vary.
