It looks like this could be used for some form of steganography. You need the right mirror form for decoding.

- jkhdigital 1y agoCan you give a specific example? The term “anamorphic encryption” was used in a paper from EUROCRYPT 2022 and I don’t see any prior formal study of the subject. A follow-up paper from PoPETS 2023 establishes that most of the widely-used cryptosystems introduced over the past few decades are indeed capable of anamorphism but nobody used the term “anamorphic encryption” until the last few years. To say that they have been used for “hundreds” of years seems like a sweeping generalization in need of better context.

Sure it didn't use the exact word but the concept is there. https://www.openculture.com/2017/11/why-did-leonardo-da-vinci-write-backwards-a-look-into-the-ultimate-renaissance-mans-mirror-writing.html https://www.openculture.com/2017/11/why-did-leonardo-da-vinc...
- jkhdigital 1y agoNot trying to be argumentative, but mirror writing is neither encryption nor steganography. The concept is not there.
- lawlessone 1y agoUsing 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"
- jkhdigital 1y agoMy PhD research is in steganography. I was familiar with those papers because I’d read them before.
- tsumnia 1y agoWhen I saw the video I wondered how many layers of refraction you could achieve while maintaining coherent images. The pixelated style they should might be the easiest use to develop this from.
