1. A determination method implemented by a computer, the determination method comprising:
generating face image data from which noise is removed by a specific algorithm from face image data when the face image data is acquired;
generating difference image data concerning difference between the face image data that has been acquired and the face image data that has been generated;
determining whether the face image data that has been acquired is a composite image based on information included in the difference image data; and
determining whether the face image data that has been acquired is a composite image based on information included in frequency data generated from the difference image data in a case where the face image data that has been acquired is not determined to be a composite image.
