Using Watermarks to Prevent Leaks

Watermarks are used as a way to retain control of information in a world where information is uncontrollable. They are a type of metadata that is inserted into data so the creator of the watermark can have a measure of control over how this data is used, viewed, and distributed. Watermarks can be human readable or machine readable, and they can be visible or invisible. Sometimes watermarks have flaws. They can be stripped out of the data or altered.
