Watermarks are simple, cheap to apply, and can be dynamic. But they are visible, which means they can be easily removed. And this is the main difference between watermarks and the LeaksID (G-71 Inc.) technology. Using LeaksID, the system invisibly marks documents, and the marks cannot be recognized and removed.
To remove the LeaksID mark, you need to either delete all the document's text or completely retype it in another document. But in that case, it will be a falsification of documents, and the fake document doesn't have any value and looks like gossip.
