Abstract
Encoding element (100) at least selectively transparent to an infrared or ultraviolet light radiation, incident thereon on a first incidence surface (101), wherein—in the volume defined by said encoding element (100)—a plurality of areas (104) is provided, previously selected and arranged according to a predefined pattern wherein at least one polarisation characteristic of the optical radiation (200) that is incident thereon is varied, wherein the variation of said polarisation characteristic of said incident radiation is varied according to a localised alteration pattern biunivocally associated to a predefined ciphering key, and wherein said plurality of areas is arranged between said first incidence surface (101) on which said infrared or ultraviolet light radiation is incident in use, and a second output surface (102) of said infrared or ultraviolet light optical radiation.
