Abstract

The majority of prior art security markings (barcodes, holograms, etc.) are easy to counterfeit, expensive to produce, also accessible to counterfeiters or are non-machine readable. The novel method overcomes said disadvantages. A random pattern is applied to the product or the label. It is highly important that said method is that a very large number of different patterns are produced and that one such pattern can be produced at low costs. The effort required to produce a specific pattern is obviously much higher (e.g. random distribution of effect pigments). A finger print in the form of a data set is extracted from the random input pattern, said finger print containing the individual characteristics of the pattern. Said finger print is individually stored for each security marking. The finger print is extracted again during authentication and is checked to see if it matches the stored finger print. The security marking can generally be used to protect against forgery e.g. for money, documents, water marks, vehicle number plates etc.
