Abstract: A method for producing a multilayer body (1), in particular laminating film or transfer film, wherein a replication layer (12) is applied to a carrier layer (11), and a first graphic code (21) is Fourier-transformed into a two-dimensional Fourier pattern (23) and the two-dimensional Fourier pattern (23) is binarized in order to obtain a binarized two-dimensional Fourier pattern (24), and the binarized two-dimensional Fourier pattern (24) is transferred onto a stamping tool, and the binarized two-dimensional Fourier pattern (24) is molded as a stamping structure into the replication layer (12) at least partially in a first region by means of the stamping tool.

Abstract: A method for attaching a number of unique identification codes (13) from a set of unique identification codes (13) to a number of objects, wherein the unique identification codes (13) differ from one another, wherein the unique identification codes (13) form a predefined code sequence which defines a first unique identification code (13) and a last unique identification code (13), wherein the method contains the following steps: attaching the number of unique identification codes (13) from the set of unique identification codes (13) to the number of objects, with the result that one unique identification code (13) is attached to each object (5); optically detecting a unique identification code (13) from the set of unique identification codes (13) with the aid of a detection unit (17) and detecting an item of additional information; inferring the attached unique identification codes (13) on the basis of the optically detected unique identification code (13) and the detected item of additional information.
