Over the past decade with the increasing popularity of Internet and digitaltechnology images in digital format have become ubiquitous. At the same timewith the breakneck speeds of the development of technology that allows fordigital images to be manipulated and distorted detecting tampering orvalidating authenticity of digital images are of great importance for forensicpractitioners. This book provides the first general framework based onuniversal statistical properties of natural images of detecting tampering andauthenticating digital images that has been successfully applied to threeproblems in digital image forensics 1 differentiating photographic imagesfrom computergenerated photorealistic images 2 detection of steganographyhidden messages in digital images 3 differentiating lively captured andrebroadcast images in biometricbased authentication systems and also todigital authentication and identification in art forensics. This book shouldhelp bridging the research work in image modeling and forensics and should beespecially useful to researchers and practitioners in image modeling digitalimage forensics or related fields. «
