%X <p>A new forgery detection scheme is proposed in case of modification of images formed naturally. Illuminating an object leads to make diffuse refection on surface of the object, its shadow appears in the projection plane. Once images are tampered, it is difficult to maintain the consistency of these natural features. Therefore, the uniformity between the direction of light estimated with an object in a photographic and the area of the light direction on the basis of cast shadow, will not effectively work for a detected image of multiple objects, but determine if an image with only one is tampered or not.</p>
