Sequence Alignment with Dynamic Divisor Generation for Keystroke Dynamics Based User Authentication

Table 5

The average of equal error rates with the standard deviation of equal error rate (after plus-minus sign) by using different statistical metrics in both sequence alignment algorithm and SADD. The highest performance of the algorithm and statistical metric is in bold.
