In the field of digital image forensics, image source identification aims at establishing a link between an image and the device that generated it. All digital pictures taken by the same device are overlaid by a specific pattern, which is a unique and intrinsic fingerprint of the acquisition device. Such a fingerprint can be estimated as the difference between the content and its denoised version, obtained via denoising filter processing. Proposed is a performance comparison of different filters for source identification purposes.
