Statistical Decision Theory

The problem of recognizing the signature of a given iris as belonging to a particular individual, either after exhaustive search through a large database or just by comparison with a single authentication template, can be formulated within the framework of statistical decision theory [22], [27]. This framework also resolves the critical problem of assigning a confidence level to any such recognition decision. By this approach we can convert the problem of pattern recognition into a much more expedient task, which is the execution of a simple test of statistical independence.
