Digital data file encryption method for e.g. hard disk of computer, involves creating representative data of tomographic image from harmonic image, where tomographic image has data representing intensity, luminance and/or chrominance levels

Abstract : The method involves choosing representative data from primary harmonic images (H), where each image comprises data representing intensity, luminance and/or chrominance levels (NH) listed according to coordinates in the primary image. Representative data of a tomographic image (I) is created from the harmonic images, where the tomographic image includes data representing intensity, luminance and/or chrominance levels (NI) listed according to coordinates in the tomographic image that forms a mother key (CM) for encryption. An independent claim is also included for a memory readable by a computer system and including data representing a tomographic image with data representing intensity, luminance and/or chrominance levels.
