摘要： A system for generating a plurality of noise-deteriorated images from an image displayable on a computer display for deterring unauthorized reuse of the image is disclosed. The system relates to transforming an image displayable on a computer display into a plurality of frequency components, and generating a noise sequence for each frequency component in the plurality of frequency components, each noise sequence having a plurality of noise numbers. The system also relates to selecting, in relation to a first noise-deteriorated image, a first noise number from each noise sequence, and deteriorating each frequency component in the plurality of frequency components using the first noise number from each noise sequence corresponding to each frequency component in the plurality of frequency components to form a noise deteriorated frequency component in a first plurality of noise-deteriorated frequency components. The system further relates to transforming the first plurality of noisedeteriorated frequency components into the first noise-deteriorated image for displaying on the computer display.
