Cinavia Copyright Protection

Holy shit niggers:

https://en.wikipedia.org/wiki/Cinavia

The watermarking and steganography facility provided by Cinavia is designed to stay within the audio signal and to survive all common forms of audio transfer, including lossy data compression using discrete cosine transform, MP3, DTS, or Ogg Vorbis. It is designed to survive digital and analogue sound recording and reproduction via microphones, direct audio connections and broadcasting, and does so by using audio frequencies within the hearing range. It is monaural and not a multichannel codec.

o Only a single channel of audio is required to detect the watermark
o The watermark is able to survive re-recording through a microphone
o The watermark can be detected through "the production, duplication, distribution, broadcast, and consumer handling of recorded content"
o Different copies of otherwise identical works can be distinguished

Let's brainstorm ways to extract the waveform pattern from this!

When media with the watermark is played back on a system with Cinavia detection, its firmware will detect the watermark and check that the device on which it is being played is authorized for that watermark. If the device is not authorized (such as not being an authorized movie projector in the case of a cam bootleg, or not utilizing AACS in the case of a copy of a commercial Blu-ray disc or CSS in the case of a copy of a commercial DVD), a message is displayed (either immediately or after a set duration) stating that the media is not authorized for playback on the device and that users should visit the Cinavia web page for more information.

Computer-savvy users know better than to buy backdoored shit like that, so they only people this might actually affect is iPhone-wielding mouthbreathing retards. Never mind, the only place it's currently implemented is BluRay/media players. Play your movies on a real computer and you've bypassed it.

Also cue DoS attacks by inadvertent triggering of firmware.
