A new scheme for sharing secret color images in computer network

Based on visual cryptography scheme, an effective and generalized scheme of color image hiding is proposed. By means of little additional computations, it goes through a color index table to hide and recover a secret image. In this scheme, a secret color image hides itself in two arbitrary color images, which can be constructed and then are kept by two participants, separately. Note that the processed images are significant. It is a kind of camouflage. Later, the secret image can be recovered through the same simple algorithms on two camouflage color images. This paper proves that only one of the two camouflage color images cannot reveal the secret image. Thus, the hidden information is secured.
