" is the most complete of the authentication packages currently available. It offers the tools needed to determine if an image is a camera original with several features including EXIF analysis, Quantization Table extraction, file structure analysis, and tools for determining if a file has been resaved. Then, it also offers quite a number of tools to assist in finding areas of an image that may have been altered - from ELA and DCT Mapping to Correlation Mapping and Clone Detection. It also has PRNU capabilities to determine if an image is from a specific source camera. It is the most complete image authentication software currently available."
"Programs like include some or all of the usual tests (Structure, EXIF data, Luminance & Chrominance Quantization tables, DC & AC & overall Discrete Cosine Transform coefficients, compression and error levels, color filter array & photo response non-uniformity matching, color space decomposition, Error Level Analysis, neighboring pixel correlation mapping, histogram equalization, and high-pass filtering). The problem is that once an image has been repetitively resaved in a lossy format, you can no longer detect any tampering except that the image is not an original. Especially is the metadata is absent, which is usually the case. That said, I have been most impressed with extensive forensic tool set."
