This book comprises of independent research work of an author, in the field of Digital Image Forensic. It gives an insight of Image storage methods. The algorithms required for the detection of Copy Paste regions(CPR)in a Digital image, are revealed. The devised techniques are also implemented using MATLAB, and the results of them are discussed. The algorithms suggested here can be translated into the desired technical tool, so as to perform the Forensic operations. It serves the purpose to the students who want to get an insight in Image Forensics, and also to the scientists who are currently working in the area of Image Processing and Analysis. Realizing the fact, that the technologies available for detecting the forgery or doctoring in digital images are in infantile stage in India, an attempt to give the basic idea can help the researchers and investigators.
