In addition, only limited biometrics that can be measured passively are applicable for continuous authentication. However, continuous authentication is a heavy processing load for the system. In this study, possible methods for conducting a continuous authentication are examined from the viewpoint of reducing the processing load, and two types of on-demand authentication approaches are confirmed to be effective.}, publisher = {Springer}, title = {On-Demand Biometric Authentication for?System-User Management}, year = {2022}, yomi = {ナカニシ, イサオ} }
