Abstract
A detection device monitors a communication event including communication by humans when a legitimate user accesses sensitive data for each legitimate user. The detection device builds a profile of the user indicating normal behavior when the user accesses the sensitive data by performing machine learning on a result of the monitoring. After that, the detection device acquires a communication event when a user to be authenticated accesses sensitive data. The detection device determines whether behavior of the user to be authenticated indicated in the acquired communication event corresponds to normal behavior when the user accesses the sensitive data indicated in a profile of the user, and outputs a result of the determination.
