It's almost like steganography.

Seems like a good opportunity for steganography to make its move

Perhaps they use some form of steganography.

That's what steganography is for.

Someone should run that image through a steganalysis tool.

How will it deal with steganography?

Maybe it's a watermark technique.

Thieves can already scrub out visible watermarks with content-aware fill etc.
