Abstract

Procédé permettant d'effectuer le mappage d'une oeuvre (graphique, document, etc.) constituée d'un grand nombre d'octets de façon à obtenir une chaîne binaire relativement petite afin de faciliter la protection contre la copie. La technique consiste à créer, à partir de l'oeuvre, une première chaîne caractérisée par le fait que si quelqu'un modifie ladite oeuvre à un certain degré (modification intentionnelle ou simple vieillissement), une seconde chaîne (générée par la technique de l'invention) associée à l'oeuvre modifiée n'est pas sensiblement distincte de la première chaîne. Une fois que l'algorithme leur a été appliqué, des oeuvres similaires donnent des chaînes identiques ou similaires. Le propriétaire du contenu à protéger peut donc appliquer cet algorithme aux copies de l'oeuvre à des fins de protection contre la copie.
