Anti-Forensics of Photo Response Non-Uniformity of Digital Images

The digital image processing is to be used in Antiforensics of photo response non-uniformity of digital images. Fingerprints are one of those irregular twists of nature. The fingerprints are used for authentication and identification processes in forensic tasks such as detection of digital forgeries. Forensic tasks can to be performed in device identification problem, device linking problem, fingerprint matching problem. For random projections the compression technique is to be required with no information loss and to be measured by PRNU values. Fingerprint matching is still a challenging problem for reliable person authentication because of the complex distortions involved in two impressions of the same finger.
