A Method of Digital Image Source Forensics Based on Wavelet Higher-Order Statistics

In order to identify whether the image is from a camera or other electronic devices, this paper presents an image source forensic method based on wavelet higher order statistics, which uses the influence of the generation path on image properties and mathematical statistics. From the perspective of multi-scale analysis of the image, we study the unique characteristics of the image from different sources in the transform domain, and extract the high-order statistical characteristics of the wavelet domain in the digital image to determine the source of the image.
