Hiding secret messages into index-based images is difficult because it suffers from an amount of image degradation and a limited hiding capacity. In this paper, an adaptive steganographic scheme for index-based images is proposed. The codewords are grouped into sub-clusters according to the relationship among codewords. Also, the size of the sub-cluster determines the hiding capacity of the proposed scheme. The experimental results show the performance of the proposed steganography. In comparison with the least significant bit modification method (LSB), a better stego-image quality is obtained by the proposed scheme. In comparison with Jo and Kim's and Fridrich's methods, a higher hiding capacity is provided by the proposed scheme while the near image quality remains. Furthermore, an adaptive hiding capacity is achieved by the proposed method.
