As I learned last week, this doesn&#8217;t seem to be random but influenced by surface characteristics, see the video of the laser surface authentication technology (LSA) at the <a href=\"http:\/\/www.webvideo.bayer.com\/en\/protexxion-en.videox?time=625&#038;kb=514&#038;wmp=1&#038;qtp=1\">Bayer<\/a> website. As far as I could trace it, the technology has been invented by <a href=\"http:\/\/www3.imperial.ac.uk\/people\/r.cowburn\">Russel Cowburn<\/a>, made its way to Ingenia Technology Limited (ITL) and is now hosted at Bayer and branded as ProteXXion(R). Surface characteristics can be stored in a 750 Bytes string; objects are recognised at a speed of up to 5 m\/s.
