Gimp Forensics

This project tries to implement some classical Image Forensics analysis algorithms to Gimp. Whether because you want to run those tools in your local machine (due to legal reasons for instance), or because you want a better understand of those algorithms you can use Gimp Forensics.
So far Gimp Forensics implements the follow algorithms:

• [Error Level Analysis]
• [JPEG Ghost]

Both those algorithms work in a similar fashion, by taking advantage of [double compression artifacts] that may appear in image lossy compression algorithms such as JPEG.

Installation

Both algorithms are Gimp plugins written in python. To make use of them, just copy all files to Gimp plugins folder. If you don’t know where this folder is located, open Gimp and go to Edit> Preferences > Folders>Plug-ins.

As soon as Gimp is restarted a Forensics Menu will show up with the plugins.

That’s It!
