To evaluate the equal error rate EER (%), we have used a matching algorithm, presented by Medina-Perez et.
Table I shows that a combination of our algorithm in both stages and in individual stages with some other algorithms (Gabor, STFT, Yang) can additionally lower the equal error rate EER, and even speeds up processing when a combination with Yang algorithm is used.
As can be seen from Figure 6, increasing intra-class variability leads to an increase in the equal error rate
EER, an increase in the FRR and a decrease in the FAR.
False accept rate (FAR), false reject rate (FRR) and equal error rate
(EER) are used as the performance metrics in our experiments.

The security can be measured statistically, with equal error rates
for false acceptance and false rejection ranging from 4 percent to fractions of a percent depending on the implementation methods and technology used.
The paper also reviews issues such as user acceptance, failure-to-enroll rates, throughput speeds, and equal error rates
, which are the point at which the false accept and false reject rates are equal.
