As in the sample set, we use 300 keys (30 subjects, 10 keys per subject). The entropy values of these keys are given in Figure 6. The more the entropy value approaches to 1, the more random the key is. As can be seen in this figure, 83.67% of the keys have entropy values that are greater than 0.994, and also all of the keys have entropy values that are greater than 0.98, which implies very good randomness. It is important to note that these keys are generated by hashing the common minutiae. It can be normal to have high entropy for the hash results, because the hash functions kind of randomize the input string. Therefore, the entropy values of the concatenation of common minutiae are calculated as well. The concatenation is as follows, x y type. The entropy values of these concatenations are given in Figure 7. Although the
