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

Table 6

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