Biological determination device and biological determination method

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of determining with high accuracy whether a captured face is a living body such as a human being or a non-living body such as a photograph, a video or a doll, and by extension, suppressing the breakthrough of face recognition. do. SOLUTION: A detection means for detecting a face from an captured image, a temperature of a face region which is a region of a face detected by the detection means, and a face which is a region around the face region. The detection when the temperature of the face region is higher than the temperature of the extraface region by a predetermined threshold value or more based on the acquisition means for acquiring the information of the temperature of the outer region and the information acquired by the acquisition means. A determination means for determining that the detected face is a living body and determining that the detected face is not a living body when the temperature of the face region is not higher than the temperature of the extraface region by the predetermined threshold or more.
