Can the process of generating a password based on the transformation of random 3D data into a 2D data chain have better entropy than other methods of generating 2D random data chains?

    I'm voting to close this question as off-topic because it is not about information security. You essentially ask how to convert some imaginary 3D QR code into another (2D) visual form. For this question it does not matter if you want to use the other form to generate passwords or something else, i.e. the transformation you ask about is not specific to information security. – Steffen Ullrich Jan 28 at 14:08
  • This type of transformation, any 3D object to signs/characters, would be seen as another technique (perhaps a policy) to create passwords. The passwords are about the security of information, as I understand it. So maybe me (or anyone) can just reformulate the problem? – merlenoir Jan 28 at 14:25
  • What you say is quite unclear to me. You want to create passwords from 3d qr code, I see no point in doing so. The best passwords are made from random data. So for example, 5 random english words. You don't need 3d qr code to do that. – Aria Jan 28 at 14:26
  • Not necessarily QR. It could be anything, also ~random event like water drops states closed and frozen in 3D space. – merlenoir Jan 28 at 14:37

    I don't understand what you are trying to do. Could you perhaps explain what concrete problem you are having? And perhaps define "3D data" and "2D data". – Anders Jan 29 at 8:34

It sounds like you're describing one of two things:

  1. A process in which data is generated somewhat randomly, but constrained by being mapped to a 3D structure with certain properties. If so, it will necessarily be less random than a method that is not constrained in that way.

  2. A process in which completely random data happens to be projected into 3 dimensions. If so, the initial projection is immaterial to the underlying entropy of the data ... but any subsequent transformation (converting to raw 2D equivalents, using base64, etc.) could do nothing to improve the entropy. And that transformation might make it worse if it has non-random components.

Either way, the process you're describing would be no better than random data - and could be worse.
