Abstract:
Data hiding technology is that embedding the secret message into the cover image, forms the stego-image. The stego-image must keep well quality of image under high capacity of embedding for achieving security. In 2006, Chang et al. [2] proposed a data hiding method based on RLE which can carry beneficial result. Recently, Lin and Hu [8] proposed a similar high capacity RLE steganography which improves the compression ratio and image quality. However, their method is not excellent in aspect of adaptability. In order to improve this disadvantage, we will propose an adaptive high capacity RLE steganography in this paper. According to the experimental results, we can prove that our proposed scheme is not only to promote the adaptability of the high capacity RLE steganography but also to keep the better image quality when the encoding length is longer or the secret image is more complicated. |
