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!

Why I mentioned that the evil would be if the technology is used on DRM systems, where the consumer was not told it had. I also gave why this is a great technology, and what market this is actually great for, not the copyright mafia.

The hardware should not be doctored with the specification if not detailed to the consumer. This technology should only affect niche markets. If it does get subverted into commodity devices without clear labeling/description, it would prove disastrous to everyone. The manufacturer would get lots of returns for non-functioning hardware, because some streams of data had the same signature as one of the DRM audio streams, thus locking the device is some fashion. The customer would obviously object, and return when something was not playing. And the original author would get harassed for not being able to properly distribute the work at a satisfactory level the users would want (includes being able to play the work at their leisure, if at all).

IOW, the problem is with DRM implementations on devices the user did not request, not the audiomark algorithm.

In your scenario, stop buying hardware that has DRM in it, even if it is disabled, if you do not want/need it. There are other fields that would demand his technology, and would adopt it for those reasons, not commodity hardware (e.g. secure conference telecommunication, marking works for verifiability, authentications systems, audio operations (military applications), etc.).
