Using YouTube For File Storage
First time accepted submitter ememisya writes "Ever thought it might be a good idea to store encrypted data in a QRCode video? Using this technique one could easily store 10GB of data to be available anywhere in the world, and completely free."
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.
I'm sure Youtube will _never_ notice this and your foolproof plan will be good for all time.
You might be OK with some steganography, but otherwise they will thwart you if more than a few people do this.
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.

I store mine in the Linux source code comments. Nobody has ever noticed.
what ever happened to the hacker mentality these days?
they would do it, BECAUSE THEY CAN. A reason so valid that it I shouldn't have to be here telling you about it.
I'm god, but it's a bit of a drag really...
I found a QSR code burned into my toast. My cellphone read it, and it said "Jesus"
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 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, and drew on it. It still worked. Then I skewed the image using MS Paint. It still worked. Then I decided to go from 172 pixels to 86 pixels (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. 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.
