The invention relates to a security marking (100), a method and a device for reading and decoding the security marking (100), a security document (150) marked with the security marking (100), and a method and a system for verifying and authenticating said security document (150). The security marking (100) comprises a machine readable marking (130) overlapping with a magnetically induced layer (120) of a material including magnetically oriented reflective platelet-shaped magnetic or magnetizable pigment particles with two zones (120a) and (120b) of distinct orientations of the particles. The encoded data on the machine readable marking (130) being decodable only after the data separately read from the two zones (120a) and (120b) are gathered.
