Spatial information hiding algorithm based on data adding
基于数据叠加的空间域信息隐藏算法

A spatial information hiding algorithm was proposed. When the data stream of secret information was srambled, the secret information was distributed non-symmetrically to every digital plane of the image carrier by data adding. Experiments indicate the algorithm has good ability of preventing to be perceived and the hiding data have good ability of preventing to be checked-up and distilled. The maximal efficiency of data hiding come up to 4bits/pixel.
