1.What is a false reject rate What is a false accept rate How are they related to the crossover error rate - Essay Example This occurs when a biometric template does not tally with the person. They become unidentified or unverified by the system. This, in a working environment, can cause unnecessary frustration on the staff, logjams, thus reducing productivity (Jain, 1999). False Accept Rate also known as Type II error or False Match Rate (Jain, 1999). It is the degree of probability that the biometric system will incorrectly accept input pattern of the unauthorized persons to the non-matching template, thus, being identified by the system. Cross Error Rate, also known as the Equal Error Rate (EER), is the point at which the False Reject Rate and the False Accept Rate are equal (Jain, 1999). When the identifying device gets to be more sensitive and accurate, the false accept rate (FAR) goes down, and the false reject rate (FRR) goes up, hence, the intersection
