WASHINGTON—When the National Research Council released a report criticizing the use of biometric technology, many in the security industry took notice. The 2010 report, Biometric Recognition: Challenges and Opportunities found that “human recognition systems are inherently probabilistic and hence inherently fallible; the chance of error can be made small but not eliminated. System designers and operators should anticipate and plan for the occurrence of errors, even if errors are expected to be infrequent.”
