Abstract: A non-transitory computer-readable recording medium stores a program for causing a computer to execute a process, the process includes acquiring an image data group in which a target person appears from a storage unit, identifying a first behavior of the target person, of which a frequency of appearance is lower than a frequency of appearance of a second behavior by using the acquired image data group, and when it is detected that image data, in which the target person appears and which is displayed on a screen, has a suspicion of spoofing, outputting a message prompting the target person appearing in image data to take the identified first behavior.
