“…Niimi's scheme [3], for instance, embeds a message based on the Green values of the colors for the target pixels. The other retains the colors of the entries and may reorder the entries in the palette [7][8][9][10][11][12][13]. EZ stego scheme [7] sorts the palette by luminance and embeds message bits into the LSBs of the indices.…”

Abstract. We propose a high-capacity data hiding scheme for palettebased images that does not seriously degrade the image quality in this paper. The proposed scheme can embed a multiple-bit message within the unit of a pixel matrix by using Euclidean distance, while some conventional schemes can embed only a one-bit message per pixel. The stegoimages created by using our scheme offer a better quality compared to those by the conventional scheme. Moreover, we have obtained these results with low implementation cost. The experimental results show that the proposed scheme is efficient.

“…Thus, the schemes should increase the computational cost of the calculation for adding and removing entries. Our scheme adopts the latter schemes [7][8][9][10][11][12][13].…”
