Hiding Information in Color Images Using Small Color Palettes

  • Conference paper
  • First Online:

Part of the book series: Lecture Notes in Computer Science ((LNCS,volume 1975))

Abstract

The small size of a color palette is utilized to include hidden information in the true-color image. Adaptive vector quantization is performed to define color palette, which is used for purposes to extract the hidden information. The resulting Voronoi tessellation is approximated by 3D cubes to define regions centered in the prototype vectors that are used to code hidden information. The regions are partitioned into cells the identity of which encode the hidden information in each pixel.
