In recent years, research on behavioral authentication has been increasing. Behavioral authentication is believed to be suitable for continuous authentication, which can detect changes in the user of a device after logging into a service. However, many previous studies have not addressed how long it takes for an authentication system to detect this change after the user has switched. Therefore, in this paper, we conducted experiments to measure the time it takes for an authentication system to detect imposters while varying the parameters of the authentication system known as the “Time Window”. Additionally, within the same experiment, we also evaluated the authentication performance using the True Acceptance Rate (TAR) as the evaluation metric. The results revealed a trade-off relationship between detection time and authentication performance. The experiment used data of 100 individuals randomly selected from approximately 57,000 individuals.
