So the individual dot patterns are fixed in hardware? That's clever. (A former colleague of mine has a vaguely related patent. They create unique patterns inside of chips by applying (sputtering) material at an angle, which creates chaotic patterns that cannot be copied by lithography, so the chip is in principle unclonable.)
