Image and text forensics

I was looking for some simple tools for clone detection in pictures – unfortunately or luckily – there is no one button solution also in 2020.

To extract the pictures I use unar (“brew install unar”) which preserves much more detail than a screenshot. For the next step, I can recommend Forensically, Fotoforensics or Reveal.

Maybe there are also situations where some some individual adjustments are needed where I move to Affinity like in the following picture.


For text plagiarism check, it probably needs some paid service: docoloc, Plagscan or Turnitin (German researchers may get an account at GWDG in Göttingen). For simple text comparison I use BBEdit while for PDFs I suggest Copyleaks.
