Method for finding and digitally evaluating illegal image material
First Claim
1. A method for automatically finding and digitally evaluating illegal image material, wherein a data memory is searched for image material, the method comprising:
- classifying, by a computer, found image material from the data memory that depicts image content that is potentially illegal image material;
performing, by the computer, an age determination of the depicted persons in the image material classified as potentially illegal image material, and determining whether at least one person depicted in the image material classified as potentially illegal image material falls below a predetermined age;
after performing the age determination, detecting, by the computer, biometric features of the persons shown in the potentially illegal image material and comparing the detected biometric features with at least one database containing previously detected biometric features; and
detecting, by the computer, at least one contained additional feature in the potentially illegal image material and comparing the at least one contained additional feature with at least one relevant database,wherein a personal visual inspection of the image material is not performed.

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.
