1. 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 each other is measured and stored in a database, the method comprising:
acquiring an image of the pigment domains,
identifying two-dimensional coordinates of each pigment domain captured in the image,
determining a two-dimensional distance of each pair of two pigment domains, or determining an angle of each triplet of pigment domains, or determining both,
saving the distances and angles determined in a list,
storing the list in a database, the list being enriched with meta-information about manufacturing parameters, or finishing parameters, or both of the object, and,
applying a database identification as information unit to the surface of the object, wherein the information unit is configured to be uniquely assigned to the database.
