LATENT SCRAMBLED IMAGE

An image formed by strokes or raster elements that are printed in the background pattern or portrait so that the image is not visible to the naked eye. The image is pre-fragmented and encoded using special algorithms. A latent scrambled image is visualized and decoded with the use of decoding devices (filters for visualizing latent scrambled images) or special software.
