PROCEDURE FOR IDENTIFICATION OF OBJECTS BASED ON FORMING AND VERIFYING THEIR SURFACE ROUGHNESS AS WELL AS OBJECTS SUITABLE TO BE IDENTIFIED

摘要

Process of identification a kind of the present invention relates to to(for) object, based on generating and verify its surface roughness, the label for wherein marking that make that object and picture and/or code will be generated on its surface rough, it is preferred that with other identification data objects will be stored in storage computer and/or portable method for storing and, when recognizing, the label of image and/or code be placed on object will with those/that storage. Special process, therefore roughness of the three dimensional indicia comprising basic structure arranges in chaos generation passing through printing treatment: by random galvanic corrosion and/or by random galvanic corrosion. The present invention also relates to a kind of objects to be suitable for identifying, has in the markd any claim 1 to 7 generated according to the present invention and/or by other physical-chemical modes and/or optically accessible surface. Novelty of the invention is that, and the surface roughness of basic structure has chaotic arrangement.
