I figured this was the place to ask.
I had an idea, and I supposed people with knowledge in graphics programming and theory could enlighten me.
I had an idea that paper can be repurposed to backup computers. I don't mean printing the source code of a program on paper. What I mean is that the computer can look at an image, and execute the encoded program. Something like barcodes, but with more memory.
Barcodes store information. QR codes store information. So I tried to store a paragraph in a QR code, and it was too much to handle.
I was wondering how much data can be stored in a pixel. Could pixels possibly store data other than color, like text? Or could colors represent text in a way? Can colors be converted to text?
This idea came about when thinking about a new type of security, which is really an old type of security. Paper.
Why paper? I don't really know yet.
Perhaps something like a modern punch code/card system?
Any links to good resources on topics that might be of interest to me would be much appreciated.
