Since this signal or pattern is present in each unaltered copy of the cowcatcher image, the digital Watermark may also serve as a digital check sensation for the copies. The desirable characteristics of a Watermark are Watermark should be springy to standard manipulations of either nature.

A robust, secure, ultraviolet Watermark is imprinted on the image I, and the Watermarked image WI, is distributed. The generator keeps the real image I. To prove that an image WI or a chance of it has been pirated, the author shows that W contains his Watermark (to this purpose, he could but does non have to enjoyment his original image I).
