Abstract:
A method for marking an article with an identification pattern which may include information relating to the article and/or to the use thereof, the method including: defining an alphabet of a plurality of symbols; defining, for each symbol, at least two valid states and at least one invalid state; developing a reference pattern including a set of symbols from the alphabet; developing at least one representation of the reference pattern by allocating a specific valid state to each symbol of the reference pattern; and applying a marking, reproducing the representation of the reference pattern, onto the article.
