Title: When enough is enough: early stopping of biometrics error rate testing

One consideration for this is how much testing is to be completed. In this paper we apply sequential testing methodology to testing whether or not a biometric device has an error rate below a certain bound. This approach has the advantage that the testing can be stopped at any time. A decision can be made once there is enough evidence to support or reject the hypothesis of interest. Application is made to biometric error rate data for three different modalities -facial recognition, hand geometry and fingerprints. Our results show that this approach can produce more efficient and less costly tests of biometric devices.Read More
