Authentication method and authentication system

A method for authentication and/or identification of persons, objects or service systems by security features, comprising the steps of:

• a. providing a material, a structure, a substance or a composition for the generating of a security feature,
• b. assigning this material, the structure, the substance or the composition or parts thereof or an image of these to a specific person, an object, a medium or a service system,
• c. capturing the image of this material, the structure, the substance or the composition and storing in a memory device at a first time point,
• d. comparing the image of this material, the structure, the substance or the composition with the image stored in the memory device,
• wherein the material, the structure, the substance or the composition or the image of these is actively changed by a physical, or mechanical impact or feature, so that the resulting structure or property is unpredictable, and
• that at a later time point the image of the material, the structure, the substance or the composition is captured again and the thus obtained current image is compared with the stored one in the storage device,
• wherein the person and/or object and/or the medium and/or the service system is then authenticated positive by the security feature, if the material, the structure, the substance or the composition vis-à-vis the image stored in the storage device or parts thereof has/have at least partially changed between the two time points,
• wherein the change of the security feature comprises a mechanical impact, a stretching, a drawing, of a material, a mechanical merging of surfaces, the impact of a flexible substrate on the overlying surface or the storage of voids and or particle in a material or substance, and
• wherein the material, the structure, the substance or the composition continuously changes.
