This method describes the advantages of a signature verification or any other biometric methodology having multiple tries. Traditional verification techniques acquire a test sample and compare with a model and a decision is made as to whether the test sample is genuine or a forgery. While it is clear that allowing a second try will reduce the false rejects, it will also increase the false accepts. However, from our experiments, the increase in false accepts was small compared to the dramatic reduction in false rejects. At the 1% false rejection (FR) rate, the addition of the second try reduced the false acceptance (FA) rate from 4.7% to 1.3%. So, in applications where very low FR is required, allowing the signer a second try appears to be a good option.
