Sample Comments
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.
You could use steganography to store the redacted parts.
Thieves can already scrub out visible watermarks with content-aware fill etc.
