It is a common practice followed by forger to hide traces of resampling & splicing. However the tampered region usually has a different JPEG compression history than the authentic region. ...
It identifies forgery by searching ghost which appears in resultant difference image after subtracting it from its various recompressed version at different quality levels. ...
Since both acquire dissimilar compression data JPEG forgery detection techniques try to categorize difference in compression. ...
