  Not trying to be argumentative, but mirror writing is neither encryption nor steganography. The concept is not there.

    Using the mirror to make it difficult to transcribe seems like a similar concept. Sure it's not exact phrases you'll find doing "google research"

      My PhD research is in steganography. I was familiar with those papers because I’d read them before.
