FIAS_256FIAS - Forensic Image Analysis System provides forensic examiners a complex forensic tool to investigate digital images integrity and asses their authenticity.

 

"FIAS_b_shadow 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."

George Reis, Forensic Image Analyst at Imaging Forensics and author of Photoshop CS3 for Forensics Professionals

 

"Programs like FIAS_b_shadowinclude 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 FIAS_b_shadowextensive forensic tool set."

Doug Carner, DABRE/CPP/CHS, President at Forensic Protection, Inc.
