Abstract: The invention broadly comprises a computer-based method and system for verifying an electronic voting process, comprising the steps of generating an original digital fingerprint of an electronic record at a first time and transmitting the original digital fingerprint. The method generates a validation digital fingerprint of the electronic record at a second time later than the first time and compares the original and validation digital fingerprints. The method generates and compares digital fingerprints of voting software during certification and testing, during installation in a voting machine, while the machine is in government possession, and during active use in a voting period.

Abstract: A method and apparatus (10) referred to as a step and repeat sensitometer directs radiant energy (18) from a radiant energy source (16) into a diffuse integrating chamber (2) which uniformly mixes and directs the radiant energy (18) onto an exposure plane (14) where a radiation sensitive sample (1) is positioned so that individual areas of the sample (1) are exposed to readily adjustable levels of illuminance producing gradated exposures.
