密文图像中的可逆信息隐藏算法
Novel reversible data embedding algorithm for encrypted image
摘要
Abstract
According to the existing algorithm having encryption and information hidden process separation, limited capacity and inflexible operation problems, a novel reversible method is presented based on the chaos and the histogram shifting to overcome these disadvantages. A reversible map is used to permute the pixels in a block, after that, the histogram of each block is shifted to get space for the embedding data. The receiver can decrypt firstly and then extract information, the reverse order is also feasible. Simulation results show that the proposed algorithm is easy to implement, and can effectively expand the capacity.关键词
