摘要
Recently, Secret Image Sharing (SIS) has attracted more and more researchers’ attention, in which a secret image is divided into several shadows for sharing. In practice, the produced shadows are meaningless, and are easy to be attacked if that shadows are directly used in transmission. In order to overcome the shortcoming, the shadows would be embedded into the cover image so as to be transmitted to participants securely. The embedding methods of most schemes are based on Least Significant Bit (LSB) replacement in the spatial domain, however, the embedded data can be easily detected by steganalysis algorithm. Moreover, the embedding capacity, visual quality and security need to be improved. In this paper, a secure and effective Discrete Wavelet Transform-based Secret Image Sharing with Authentication (DWT-SISA) is proposed. In DWT-SISA, the carrier has a better embedding capacity and a better visual quality after embedding. Furthermore, for the sake of solving the issue of cheater prevention, more authentication bits are embedded into the carrier. The experimental results and theoretical analysis show that the proposed scheme is secure and effective.
