Protection of information in documents by implementing individual rastering
New raster elements have been developed with the goal to be applied in individualizing documents as graphic products. It is proposed to have the parameter choice method in choosing the raster element dynamic change. The raster element for proving assertions in this paper is derived from a mesh form. The form changes depending on the pixel blackening value, and this further depends on the pixel graphics that is the basis of the reproduction. The algorithm and code lines are given in PostScript in order to be able to use the same method repeatedly in printing documents that must be secured and individualized. Such documents must have an image basis such as, for instance, a portrait, a sculpture picture or some specially chosen graphic pattern. Data on document and function individualization with belonging parameters in the graphic form mathematical definition are systematically recorded in the database together with the other texts and numerical data characteristics for the document in question. This paper demonstrates the protocol on proving the originality of a document together with discussion on the impossibility to forge it.
