Claim 0:
1. An authentication method comprising establishing a subsequent description of an authentication device comprising one or more visible elements having a random shape and/or position and comparing said description with an original description of said authentication device,
wherein the authentication device includes a security element in the form of a tag or marking simultaneously comprising,
a unique identifier either for a product or for a set of products or for identifying a printing master on a plate of a static printer of any category that can print by rotation multiple products with the same identifier, and
intrinsic disruptors randomly arranged and with random forms, in two dimensions so as to be visible whatever an angle of picture shootings, wherein the intrinsic disruptors are colored fibers at bidimensional positions in a special paper or plastic, or the intrinsic disruptors are a non-reproducible random shape of two-dimensional stains presented by solidified and dried specific chemical varnish, and
positioning markers which consist of a plurality of dots with geometric specific features for localizing an area, which includes the intrinsic disruptors, to be analyzed for authentication,
and the method further comprises recognizing by an algorithm, from any picture shooting angle, the bidimensional printed pattern and its random components in said area including the intrinsic disruptors to be analyzed and localized thanks to said dots with geometric specific features.
