Abstract

The invention relates substantially to creating a standardized general search view and a respective standardized general comparison view and comparing the two views pixel-by-pixel, wherein the standardization is performed by generating a general view, converting to color/grey scale, through histogram normalization, downscaling, edge detection and two-dimensional Fourier transformation in order to detect and alternatively filter out foreign picture messages that have nearly the same or even the same contents.
