Didn't it turn out to be the case that SGI discovered that they got the same amount of randomness from the CCD from just taking a picture with the lens cap on?

- bostik 12y agoThat sounds plausible... do you happen to have any references at hand to confirm it?
- wyager 12y ago> they got the same amount of randomness It's hard to quantify randomness. It's possible that whatever test(s) they were using reported similar results, even though the data from a lens-capped camera might be somewhat predictable if you know the physical properties of the device. I know individual models of camera frequently have very similar thermal and electrical noise profiles, so that wouldn't be too surprising to me.
