Abstract : Digital image manipulation can modify the information presented in images. Hence the integrity of images becomes challengeable. In the field of forensics, because of easy modification in its origin and content. It is troublesome to detect image manipulation only by visualizing an image because noise, contrast has been added to remove inconsistencies in altered images. Contrast enhancement transformation is the most used operation to ameliorate the objective property of a modified image. Such transformations introduce some statistical artifacts in the histogram of forged images. Various methods have been proposed to detect changes in the contrast of an image. These methods study the statistical artifacts left in images after applying contrast enhancement operation. This review attempts to give a summary of state of art contrast enhancement forensic techniques. Keywords - Digital Image Forensics, Contrast Enhancement, Histogram, Statistical Traces.
