Abstract

The invention relates to an inscribable security film, in particular for use in the automotive sector, and to a method for inscribing it. The security film contains an identification medium which is capable of diffusion and is locally liberated or fixed selectively by means of a contactless inscription process. If the security film is adhesively bonded to a substrate, the identification medium causes permanent marking of the substrate, which ensures unambiguous identification of the object in question.
