You can make watermarks that survive manual transcription. But then you have to get a lot more clever than replacing whitespace with different whitespace, and instead encode information in parts a human would preserve. Word choice, spelling choices, punctuation, etc. provide a lot of space to encode a signal. Basically anything used by traditional authorship detection/stylometry.
- JohnFen 3y agoA few lifetimes back, when I was in high school, I developed a text stegonography program that encoded this way. If relied entirely on minor changes to grammar that didn't make the text ungrammatical. That code is long lost, and I was a kid, so never characterized it in any meaningful way. But it was interesting and seemed to work. The downside was that you had to have a fairly lengthy text to encode anything but very short messages.
