  • the security element is merged with the two halves. Due to the mechanical merging of the two halves, the serrations and edges work into the material of the untreated surface, causing material embossing, friction points and pressure points (FIG. 3B). If the security element is unfolded again with the two halves, you can see on the left half how the edges and points of the structured surface have worked. In this way, a previously rigid surface results in a structured surface which can change dynamically in the further development, namely by further mechanical actions. These can be carried out, for example, by shifting the two surfaces relative to one another or by using another surface with edges or points which change the dynamic surface during a mechanical closure. In addition, it is also possible that the dynamic half changes, for example, by flattening the edges or points of the structured surface, which changes the structure. Thus, both the left and the right half of the surface can be used as a security feature if there is a dynamic change.

Abstract

L'invention concerne un procédé et un dispositif pour l'authentification et/ou l'identification de personnes, d'objets, ou de systèmes de fourniture de services, selon lequel un matériau, un produit, une matière ou un mélange de matière, ou un aspect de ceux-ci est modifié soit eux-mêmes, soit activement, par une action ou une propriété physique, chimique ou mécanique, de telle façon que la structure ou la propriété qui en résulte soit imprévisible. Si un aspect, détecté à un moment ultérieur, de ce matériau, du produit, de la matière ou du mélange de matière, est comparé avec l'aspect mémorisé dans un moyen d'enregistrement, la personne et/ou l'objet et/ou le milieu et/ou le système de fourniture de services sont/est alors authentifié positif, lorsque le matériau, le produit, la matière ou le mélange de matière est modifié, au moins partiellement, par rapport à l'aspect mémorisé dans le moyen d'enregistrement, entre les deux moments.
