AUTHENTICATION OBJECT FOR AN ITEM AND/OR A PERSON, ITEM HAVING A CORRESPONDING AUTHENTICATION OBJECT, METHOD FOR PRODUCING AN AUTHENTICATION OBJECT, METHOD FOR AUTHENTICATING AN OBJECT AND/OR A PERSON

摘要

The invention relates to an improved authentication object (10) for persons and products. The aim is achieved according to the invention by an authentication object (10) for an item and/or a person, wherein the authentication object comprises a first layer (12a) of spatial points (14) and at least one further layer (12b) of spatial points (14), wherein the further layer of spatial points is disposed such that it at least partially overlaps the first layer of spatial points, wherein the spatial points comprise a first plurality of spatial points having a first material property and a second plurality of spatial points having a second material property, wherein the first material property and the second material property differ from each other for encoding information. Falsification is substantially more difficult for such a three-dimensional authentication object (10) than has been the case for conventional two-dimensional authentication objects.
