For some time now I had plans to rewrite copymove, a command line tool/GIMP plugin, which is able to detect image forgery from the clone tool, means it detects areas with similar patterns in an image.
As usually with side projects the rewrite idled for some time and was reignited by an email of a reporter, who actually used that tool in his profession, though the old copymove couldn’t detect an obvious tampering in his sample image. This was very motivational, and I continued writing on CopyMove2 with his sample as reference.
For some time I released some internal versions for the reporter and myself, fixed the worst bugs, and added a nice GUI with Qt. The current state can be downloaded here for Mac, Linux, Windows.
For coders, CopyMove2 is GPL’d, the source code can be downloaded here:
