Abstract
A novel system for generating random numbers is disclosed. The radioactive source emits photons, which causes the release of electrons on the surface of the detector. The detector is configured as a two dimensional array having a plurality of pixels. This release of electrons creates a splatter pattern on the detector, which is then read by the processor. Subsequent photon emissions create a second splatter pattern, which is then read by the processor. The processor compares these two splatter patterns, and generates random numbers based on these two splatter patterns. In certain embodiments, the processor creates a difference matrix which represents a comparison of the two splatter patterns. The processor then classifies each pixel in the difference matrix in accordance with certain rules. In certain embodiments, these classification rules may vary as a function of time or as a function of where on the detector the pixel is disposed.
