Abstract: A device (1) for generating encrypted images which are only visible through a polarizing filter (5) oriented in a predetermined direction, comprises: a source (3) of digital information; an LCD screen (2) connected to said source (3) to form on its front face a matrix of chromatic filters which represents images; a polarizing layer (4) oriented in a predetermined direction and located behind a rear face of the LCD screen (2) to intercept a beam of light passing through the LCD screen (2) and oriented towards an observer of the front face.

Abstract: A multi-layer film (1), depicting a colour two-dimensional image which is only visible through a polarizing filter comprises an optically active layer (2) placed over a polarizing layer (3) and configured to form the image on its face opposite the polarizing layer (3) when said face is seen through the polarizing filter, the optically active layer (2) comprising a plurality of sheets (4) of optically active material placed over each other, at least one of which is shaped to form at least one portion of the outline of the image.

Abstract: A film (1) depicting a colour two-dimensional image which is only visible through a polarizing filter comprises an optically active layer (2) placed over a polarizing layer (3) and configured to form said image on its face opposite the polarizing layer (3) when said face is seen through the polarizing filter; the optically active layer comprises a plurality of areas (4) arranged side by side in said face to form corresponding portions of the image, each area (4) being mechanically stressed to a predetermined intensity so that the corresponding portion of the image has a predetermined colour when seen through the polarizing filter. Also described is an apparatus (6) for making the film (1).
