watermark : Java Glossary

watermark
Hiding a copyright notice in a program or image to help detect piracy. If every copy of the program has a different watermark, that is called "fingerprinting". It allows tracing the legitimate owner of a pirated copy. Watermarks survive even code optimisation, obfuscation and a fair bit of program change. Ideally they don’t slow the program down. One such system is called SandMark. Sometimes watermarks are visible, or semitransparent.

How to take words, sounds, or images and hide them in digital data so they look like other words, sounds, or images. When used properly, this powerful technique makes it almost impossible to trace the author and the recipient of a message. Conversations can be submerged in the flow of information through the Internet so that no one can know if a conversation exists at all.
