Today I released (on GitHub) a simple version of a simple WordPress plugin to cryptographically sign your posts.

It works by splitting your post content up into words and stenographically inserting zero-width characters between them. Together, those characters combine into a hidden pattern that is unique to your website and that post.

If someone copies your post content, they’ll also unknowingly copy the hidden characters along with it.

A second version of this plugin could include a UI to compare someone else’s content and verify whether or not it was plagiarized from yours.

It’s also likely I will need to tweak the algorithm over time, as flaws with this first-pass approach will probably come up.

This plugin is non-destructive, so you can safely use it without worrying about your data. The worst thing that could happen is that this plugin just does nothing. 😁
