The CSS (Content Scrambling System) is the encryption method used in commercial DVD production to prevent DVD data from being copied. The sole purpose of the CSS is to protect copyrights by preventing the pirating of DVDs.
The CSS decryption, called DeCSS (De-Content Scrambling System) is an algorithm that can be used to decrypt a commercially-produced DVD, allowing it to be unlocked then copied. In January, 2000, the development of DeCSS was blamed on Jon Johansen, a fifteen year old boy from Norway. Charges against Jon Johansen were dismissed in January, 2003.
