METHOD AND APPARATUS FOR CHOOSING AND EVALUATING SAMPLE SIZE FOR BIOMETRIC TRAINING PROCESS

At least two biometric measurements of a person are collected, then a statistical measure based on the measurements is computed. The statistical measure is a bounded estimate of the discriminative power of a test based on the measurements. While the discriminative power is less than a target value, additional biometric measurements are collected. When enough measurements have been collected, a biometric template is constructed from the measurements and stored for use in future identifications. Systems and software to implement similar methods are also described and claimed.
