In our research we affect the smallest pictorial element – the pixel in order to enhance security graphics solutions. We created new programming routines that define the appearance of pixels. The general opinion is that pixels are in the shape of squares. Postscript programming language gives us options to affect the shape of pixels so that they become rectangles or parallelograms. The existing picture manipulating programs give no such options for manipulating pixels, so it becomes harder to falsify documents. Postscript defines an image through a sequence of numbers and the postscript interpreter renders it starting from the top left corner, moving horizontally creating line by line and ending with the bottom right corner. Picture display, either on the monitor or printer, seeks data about number of pixels in a row, number of columns, size of the pixel and the position of the image on a page. All these parameters we influenced by stochastic congruence methods. We created new security design solutions that can be applied in security graphics.
