1. An apparatus for confidential viewing of a fundamental image utilizing spatial multiplexing image modification, comprising:

  • (a) an image display device comprising a plurality of adjacent display regions of different polarization states.(b) a plurality of spatially multiplexed fundamental image components and related masking image components derived from said fundamental image components being displayed on said image display device in association with said display regions and in such arrangement as to render said fundamental image components substantially indecipherable to the naked eye;

    (c) said fundamental image components being representative of a fundamental image and being associated with said display regions having a common state of polarization that is different than the state of polarization of said display regions with which said masking image components are associated; and

    (d) an image viewing device having polarization means cooperating with said image display device for allowing extraction and viewing only of said fundamental image components from said image display device.
