A measure of information gained through biometric systems

作者：

Highlights：

• We propose an information theoretical measure for biometric systems.

• We present several useful properties and interpretations of the measure.

• We prove that the measure can be approximated by the relative entropy.

• We discuss how to evaluate the measure and show experimental evaluations.
