Based on a visual cryptography scheme, an effective andgeneralized scheme of color image hiding is proposed. By means of littleadditional computations, it goes through a color index table to hide andrecover a secret image. In this scheme, a secret color image hidesitself in two arbitrary color images, which can be constructed and thenare kept by two participants, separately. Note that the processed imagesare significant. It is a kind of camouflage. Later, the secret image canbe recovered through the same simple algorithms on two camouflage colorimages. The paper proves that only one of the two camouflage colorimages cannot reveal the secret image. Thus, the hidden information issecured
