Many steganography schemes were invented for the purpose of safe communication. Such previous schemes often show good and reasonable performance, however, few have been based on paletted images; it is not easy to invent good steganographic schemes with little evidence of data hiding. In this paper, we propose new hiding schemes (

) based on binary images. The proposed hiding scheme (

N

) applied to paletted images using the Optimal Parity Assignment (OPA) approach. Experimental results show that the proposed palette-scheme (3,18,9) exhibits good performance compared to that of previous schemes.
