Suppose that a particular iris scan systems generates 64-bit iris codes instead of the standard 2048-bit iris codes mentioned in this chapter. During the enrollment phase, the following iris codes (in hex) are determined.
During the recognition phase, the following iris codes are obtained.
Use the iris codes above to answer the following questions.
a. Use the formula in equation (7.1) to compute the following distances:
(/(Alice, Bob), d(Alice, Charlie), d(Bob, Charlie).
b. Assuming that the same statistics apply to these iris codes as the iris codes discussed in Section 7.4.2.3, which of the users, U,V,W,X,Y, is most likely Alice? Bob? Charlie? None of the above?
