    Ever thought it might be a good idea to store encrypted data in a QRCode video?

    Not even a little bit. Now that you mention it though, it does sound like possibly one of the dumber ideas I've heard in quite some time.

        Who would be responsible for this copyright infringement? YouTube for having encrypted video data? It could be argued that YouTube is only carrying gibberish video data. The forum?

        The student who posted it. If you want to get technical, the QR code video on Youtube is not gibberish video data. It's a copy of the movie. It's just a different carrier. Unless you think turning on SSL in bittorrent means you're transmitting gibberish data.

              I said that the student is responsible for the infringement. I never said it would be proven in court.

              Even if it could be proven in court, that would set the precendent that any file of exactly the right number of bytes could be called "infringing".

              This is because for any given set of bytes the same length as copyrighted content, there is some transform that will convert the bytes into the copyrighted content. Even if you really did start with the copyrighted content, until you perform the transform, there is no infringement.

              As an example, if I encrypted the image of a commercial Blu-Ray disk with a random key that I do not know and then posted it to someplace that anybody could download it, I have not infringed, since all I did was post some bytes. If somebody guesses the key and posts it, then they are also not guilty of infringement. The only people who might be guilty of infringement would be those who use the key and decrypt the bytes into the copyrighted work.

              • Hmm, even a single byte can be transformed into a copyrighted movie...

                Encrypting something is inconsequential in the legal sense.

                    You still think on the wrong track. Really.

                    People thought they could do the same thing with basically any crime in the books - make some changes to the way it is done so that it isn't recognizable anymore and get away.

                    Surprise, the law doesn't care about the way you do it. If you kill someone, that's murder (or any of a related, bla) and it doesn't matter if you used a gun or a knife or an orbital laser array that you programmed through a Tor network and accessed over an encrypted botnet controller interface with a hundred other layers of indirection. It'll make proving that it was you who pushed the button more difficult, but if that can be done than it's still murder, plain and simple.

                    Same thing with copyright infringement. You take a copyrighted work, apply any number of whatever operations on it, make a copy and distribute it and you're in violation of copyright, plain and simple. The number and kind of operations in the intermediate step don't matter one iota. And as long as you don't get that into your head, you'll be laughed at when they slam you. Do you think the judge will be the smallest bit impressed by anything you said above? He'll have one question and one question only and that is: Did you copy a copyrighted work without authorisation, yes or no?

                    And no, that is not something that is unique of this new digital world. That's techie bla bla. You can say the same of paint or letters. No, the book sellers don't have a copyright on the letters A through Z, but they do have a copyright on a specific number of them in a specific order, otherwise known as a novel, or a poem, or a drama or whatever.

                    No, the movie industrie does not have a copyright on 0 and 1, yes it does hold the copyright to specific collections of 0s and 1s in specific orders. Or more specifically: To the content of what these numbers represent.

                    Copyright is not a mathematical concept. You can't "defeat" it with mathematics. For all the law cares, math is a tool to apply transformations on content, but that doesn't change the fact that the content is copyrighted, end of story.

                      I am not infringing copyright because I created those words myself, so I am the copyright holder.

                      Again, don't think that playing tricks with math is the first anyone has ever come up with. Sure, mathemetically you can find a transformation function that turns Bambi into Star Wars. And once more I'm telling you that is at best

            How would you prove without the key that the video on YouTube is not gibberish video data?

            Why not use the key that you said was posted as a separate YouTube video?

            ...and the encryption key as another video onto YouTube?

        • I'm pretty sure the forum and the decryption tool maker are liable too, for "aiding in copyright infringement". There is the "letter of the law" method of interpretation and the "spirit of the law"way of interpretation and judges generally prefer to interpret the law according to who is buying their next yacht.

          The more interesting question is: Get a movie and a random bitstream; post the random bitstream online (1); XOR the movie with the random bitstream and post the result online (2).

          Are (1) or (2) infringing copyright? If so, which one, and why? Remember, independently both (1) and (2) are indistinguishable from random data.

          Also, these bitstreams can themselves be used as random input for another XOR operation.

          • Even though they're indistinguishable from random data, they are "derivative works" of the copyrighted material and are in violation. Of course nobody can prosecute or even determine this, but under the law that's how it is.

      • In my opinion the mere act of uploading obvious gibberish would be enough of argument for YouTube to delete the video. Same thing if you uploaded a video containing only white noise as the picture: it's there just to waste Google's hard drive space.
      • Well, if he's not making a profit off of it and sharing it privately its really close to grounds for fair use ;) As there is nothing wrong with creating a "digital library" of copywrited works.

        The only issue in your senario is that the copy was obtained "illegally". Which is more of a civil matter then a legal one. Since it has more to do with taping something on private property. Or thats how it use to be, I'm sure the guy would be a 50 year federal conviction now.

        Youtube definitely says you can't do that

      QRCode is stupid. What is not stupid, though, would be leveraging the fact that if you upload in a correct format that's not subject to reencoding, you can pretty much fill it with arbitrary data at 90%+ efficiency. You need to wrap it in the codec data structure format, and massage it a bit so that various bits of the codec consider it valid. It'll look like "noise", but it gives you what you want, at an efficiency orders of magnitude better than QRCode.

          No its an example of how naively relying on an uncontracted outside "cloud" service is a really dumb idea.

          Now imagine you split your data up into a Set of messages, which can be recovered by any sufficiently large subset of more than N messages? This is what tahoe lafs does, typically using 10 messages, any 6 of which can recover the original.... of course its all encrypted too.

          Then all you need is some process which periodically checks the messages and ensures that you always have some threshold (which should really be larger than N, by at least a few).

          There is also no need for QR codes to be used, thats another example of naive use. It would actually be vastly more efficient to encode the data differently, but, encoding in such ways as to not be easily detected and removed by youtube could be tricky. However, if you could find a way to minimally disguise the data so it just looks like hours of terribly boring video (like, video of your pet fish)....

          Shit you could probably just keep re-uploading the same fish video with differently encoded data and new names....nobody is going to examine hours of fish swimming to determine where the loop is or whether the two videos are of the same loop.

      Unfortunately, I don't think you could count on steganography.

What is more, you have to worry about playback problems: dynamic bitrates, dropped frames, and the like. By the time you add in all the checksums, error correcting code, and other data to make the system robust, you'd probably end up with a 10-minute video just to transmit a fe

    If you start uploading videos to YouTube with nothing but frames of QR codes, you're pretty likely to have your account closed and the videos deleted.

    It would be more robust if you made the video look like something that could plausibly be on YouTube as a "normal" video, even if it's something really boring. Probably especially if it's something really boring. Record one of your pets and use the low-order bits of the video and/or audio to steganographically include some data.

      Have you ever used a QRCode? Ever noticed that most algorithms don't recognise the QRCode when it's sharpest and level with your screen? Usually, you don't have the time to have the code be level, or in focus, before the algorithm picks it up.

      That's because QRCode are nigh indestructible. They could add a watermark [wikipedia.org] and the code would most probably still be readable (depending on the level of error correction you apply when encoding).

      For example, I took one of the Wikimedia QRCode examples [wikimedia.org], and drew on it [postimg.org]. It still worked. Then I skewed the image [postimg.org] using MS Paint. It still worked. Then I decided to go from 172 pixels to 86 pixels [postimg.org] (using MS Paint's resize function). It still worked (zoomed to either 100% or 200%). Then I decided to "reduce its resolution", so to speak, by resizing that reduced image to 200%, then back to 50%, then back to 200%, etc for 4 or 5 times, until I ended up with this [postimg.org]. It still worked.

      Now, I'm sure that I *wanted* this to work. There will be dozens of cases where even the most stupid tear of paper or poor lighting will prevent that QRCode from being decoded. But somehow, I don't think that YouTube's HD video encoding will be much of an issue for QRCodes.
