Claim:
1. Security element as originally applied by a printing technology to a substrate as a print, the security element comprising a code carrying primary information and detectable to the naked eye in visible light within the wavelength range of 380 to 750 nm, as well as a code carrying secondary information and that is undetectable in the naked eye, wherein the largest dimension of the code carrying secondary information in at least one planar direction is 2 to 40 microns, wherein the largest dimension of the code carrying secondary information is chosen based on resolution of the printing technology in such a way that the code carrying secondary information is distorted as a result of printing onto the substrate to render the code carrying secondary information non-reconstructable from the print and the code carrying secondary information attributes the security element with a predetermined statistically analyzable feature.
