Abstract: A method for finding and digitally evaluating illegal image material is provided, wherein a data memory is searched for image material. Image material that is found is classified as potentially illegal image material or as legal image material by means of a classification method on the basis of an image content that is presented. The image material graded as potentially illegal has the age of the persons shown determined, and potentially illegal image material which shows at least one person whose ascertained age is below a prescribed age is graded as illegal image material. Biometric features of the persons shown in the illegal image material are detected and are compared with at least one database which contains biometric features. In the illegal image material, at least one further feature which it contains is detected and is compared with at least one appropriate database.
