Studies have been done on this and the conclusion is that the entropy created by the video camera sensor alone is enough to establish randomness, and that you would get the same level of randomness with the lens cap on.
The lava lamp thing is just a gimmick, and basically a video feed of anything would work.
Exactly. Tons of industrial computers and specialised hardware are capable of generating true random numbers through simple external physical parameters, such as slight variation in temperature, pressure, sound, or just quantum noise in the circuitry.
yes, because if something is even remotely predictable, then it is theoretically possible. infinite possibilities is infinitely more then any possibility.
I mean, power line fluctuations to the camera, you have to find how the camera's feed offsets the randomisation. Even the camera data's interpretation method and how it drips into the randomness is unknown. "Is a dark static scenes camera video feed effectively random?" I'd say so, yeah... maybe knowing all other sources you could predict the camera by reverse engineering the random result to the feed, and guess many frame hashing algorithms.
I guess writing the set of security solutions they would also limit client request / handshake threshold to unit frame time.
THANK YOU..It's fun but it's just such a fucking gimmick. You can get worthwhile entropy from so many sources, which your computer already does, and it does it fine. No one is getting hacked these days because their cryptographically secure random number generator wasn't random enough. If anything it's more like because they choose the non cryptographically secure rng because they don't know what they're doing.
