More Information
Summary:A method for uniquely marking an object, wherein a random distribution of individual pigment domains is applied to a surface of the object, and wherein a list of distances of the individual pigment domains from one another is measured and stored in a database. Also a corresponding method for identifying an object by: capturing an image of the pigment domains, identifying the two-dimensional coordinates of each pigment domain captured in the image, determining the two-dimensional distance of each pair of two pigment domains and/or the angle of each triplet of pigment domains, storing the distances and/or angles determined in the step before in a list, storing the list in the database, the list enriched with meta-information about the manufacturing and/or finishing parameters of the object, applying a database identification as an information unit to the surface of the object, the information unit uniquely assignable to the database.
