Japan: Published International Standard for biometric authentication accuracy evaluation method (ISO/IEC 5152)

On 17 July 2024, the International Standard for evaluating biometric authentication accuracy (ISO/IEC 5152) was published. The Standard reduces the number of samples needed to assess the accuracy of biometric authentication. It is anticipated that the Standard will expedite the enhancement process of biometric authentication devices, facilitating the deployment of more precise technologies. Specifically, the Standard employs an approach using extreme value statistics to evaluate the "false acceptance rate" and "false rejection rate," which estimate the likelihood of rare events occurring. This method enables the reduction by one-third in the sample size required for accuracy assessment.
