Abstract

Method for producing a security device (1) comprising the following steps: providing at least one stochastic selector (8), generating a coupling between an identifier (11) and one particular combination of security features (6) from a finite set (5) of distinct combinations of security features based on the at least one stochastic selector (8), registering the coupling in a database (12); and applying an identification element (3) comprising the identifier (11) and a non-printable security element (2) comprising the particular combination of security features (6) according to the coupling to a substrate (22) to produce a security device (1).
