Researchers hide information in plain text
- tristanj 8y agoHidden in “plain text” when rendered using their special font. The special font slightly changes the shape of each letter to encode additional information. Title is pretty clickbait. If you copy the “plain text” to ASCII or use a regular font this won’t work.
- titusblair 8y agoGreat point but still cool it persists in screenshots!
- xiavan405 8y agoIt works with common font families, such as Times Roman, Helvetica, and Calibri, and is compatible with most word processing programs, including Word and FrameMaker
- titusblair 8y agotextmark.io is doing something along these lines but in a different way. It’s a very cool space to be in esp with advancements in machine learning. Disclaimer I am the founder.
- dmckeon 8y agoThis could be a useful variation on a trick for tracking leakage of documents: distribute N paper "copies" of a document to a pool of suspected leakers, each "copy" with tracking data embedded, and when leaks occur, match the tracking data to the leaker. Old way: use apparent typos to track, this way: use font variations, next way: use variations in kerning between words.
