By combining both moiré patterns and microlithography techniques, it can be easily recognized by the naked eye and impossible to reproduce through currently existing printer or scanner technology.

Lausanne, Switzerland–In this race for protection of property, EPFL researchers are making their contribution. Even though there has been a wide diversification of protective measures against counterfeits, technological advances in scanning and printing methods simplify the manufacture of several kinds of forgeries such as: banknotes, passports, electronic items, watches, drugs, etc. By combining two complex techniques, EPFL researchers have developed a new authentication system able to create images virtually impossible to reproduce. Their invention was published in Light, a new magazine associated with the Nature Publishing Group and dedicated to research in the field of optics.
