Abstract: A security element for the identification and authentication of objects is disclosed. The element is connected by a self-adhesive label to an object. It has features that effectively prevent non-destructive detachment of the security element from an object. The security element has an optical code for identification. Furthermore, it is provided with random production-governed features by means of which authentication is made possible: upon irradiation with electromagnetic radiation, a scattering region of the security element brings about a characteristic scattering signal. The method of using the security element is disclosed for the identification and authentication of objects and also for protection against forgeries, and a method for the identification and authentication of objects on the basis of the security element.
