摘要
The invention concerns a set of N security features (105, 106, 110), each security feature forming, alone, an authentication feature different to those formed by the other security features, the different security features being shaped such that, when the N security features are superimposed, they together form an N+1th authentication feature (112) unrelated to the N other authentication features (107, 108, 111) each formed respectively by one of the N security features.
