Abstract (en)
[origin: WO2015144509A1] The invention relates to a method and to a device for authenticating and/or identifying persons, objects, or service systems. In said method, a material, a construction, a substance, or a substance mixture, or an appearance thereof, either changes itself or is actively changed, by means of a physical, chemical, or mechanical influence or property, such that the resulting structure or property is unforeseeable. If an appearance of said material, of the construction, of the substance, or of the substance mixture recorded at a later time is compared with the appearance stored in a storage means, the person and/or the object and/or the medium and/or service system is positively authenticated if the material, the construction, the substance, or the substance mixture has at least partially changed between the two times in comparison with the appearance stored in the storage means.
