Abstract (en)

Identification document (1) provided with a security element (101), the latter comprising an authentication data (OK) decomposed into two or more components (O, K) applicated on two or more respective layers (10, 20) superimposed in a position of mutual register. Such layers comprise at least one interfering layer (11, 41, 42) to an electromagnetic wave (R) which incises on the security element (101), said interfering layer being configured in such a way that the authentication data (OK) is detectable as format by all its components exclusively from an only observation direction relating to one of the two opposite faces (A, B) of the security element (101).
