One of the most frequent methods of digital image composition is inserting image which does not exist in the original image. This kind of method is getting more elaborate because of improvement of digital processing technology. So, it is very difficult to judge that the image is true on fake by naked eyes. When we analyze the image which is suspected, we think about that the object on the image was there or not firstly. In this study, we would analyze that the image which is composed by different compression ratio image.
