This is a clear violation of the intended use of YouTube and I’m not trying to be the morality police saying this, it has significance. What good is file storage that isn’t safe or reliable? I don’t know enough about video compression to dive deeper into this but I figure if you encode the data into something that resembles an MPEG (or H.263 or whatever) video stream closely enough, you might avoid getting the data re-encoded by YouTube and becoming useless. Macroblocks are encoded as discrete cosine transformations, and the lossy part of the compression algorithm is based on reducing the accuracy at which the data is stored. Those are blocks of 8×8 pixels in the YUV color space, where usually the brightness data (Y) has 2x or 4x the resolution of the color data (U and V). I think it would be better to start by encoding the data as JPEG macroblocks. But if YT decides to re-encode your video, or if you can’t get the full resolution because your connection is slow, you’re up a creek, too. And I’m sure YouTube has thought about smart people trying to do this too.Įncoding data as black and white pixels seems like a bad idea, though: Downloading a video is already a pain because you have to figure out a way to get direct access to the video stream or file, which is basically a game of whack-a-mole. I’ve thought about doing this, many times. This allows for intermediate levels such as AES Ultra 4.5 using 36 bits, and Ultra 7 using 48 bits. AES Ultra levels use larger Sboxes and extended rounds of encryption where the table size is 16 bits for Extended AES, 24 for Extended2 AES, and Ultra Levels use the formula Ultra Level=(Number of bits / 8). 32 bit extended AES Ultra 4 is feasible for pcs if you can determine a safe generating polynomial. The unknown and undocumented number of rounds used by AES Ultra7 extends the 8bit/256 entry S-boxes to 48bits requiring 1.5petabytes of custom ROM generated by unknown Galois polynomials stored on low production quantity devices. It wouldn’t matter, the firmware encryption and frequency hopping schedule is passé compared to AES Ultra7. This assumes one can obtain boards located who knows where on an AWACS and live to tell the tale. Apparently Motorola DSP’s require uncapping and being probed to determine binary in the encryption key data bits to learn the secrets programmed on them. Posted in Software Hacks Tagged cloud storage, video, video compression, youtube Post navigationįHMUX/ERSRS-Eieio and other parlance were peppered among the conversations overheard at Xetron(a subsidiary of Westinghouse, Then Northrupp-Grumman) between a friend and coworkers developing things related to giant frisbee-carrying airplanes given freely to our NATO Allies and for some reason also to Saudi Arabia. As an alternate approach, we recommend hiding all your important data in podcast episodes. Whether this is against YouTube’s TOS is probably open for interpretation, but we’re guessing that the video site could spot these uploads with relative ease and apply a stronger compression algorithm which would corrupt them. There’s an example video, which we’ve placed below the break. The final video comes in at around four times the size of the original file, and looks like noise on the screen. It eschews RGB colour for black and white pixels, and each displayed pixel in the video is made of a block of the real pixels. The README goes into a bit of detail about how the code tries to avoid the effects of YouTube’s compression algorithm. It’s hardly a new idea as there were clever boxes back in the 16-bit era that would do the same with a VHS video recorder, but it seems that for the moment it does what it says, and turns YouTube into an infinite cloud file store. The proof of concept code from works by encoding binary files into video files which can then be uploaded to the video sharing service. Consider this though, how about YouTube as an infinite cloud storage medium? Anyone who was lucky enough to secure a Gmail invite back in early 2004 would have gasped in wonder at the storage on offer, a whole gigabyte! Nearly two decades later there’s more storage to be had for free from Google and its competitors, but it’s still relatively easy to hit the paid tier.
