A low complexity reversible data hiding method based on modulus function

In this paper, we proposed a low computational complexity lossless data hiding method. The data hiding method is based on modulus function. The basic idea of the algorithm is to compress the host data to create room for watermark. After watermark extraction, the host data can be exactly recovered. The algorithm also can be applied to near lossless data hiding with little modification. The low complexity lossless data hiding algorithm has successfully applied to speech signals and the hiding capacity is large. Finally, the experimental results have been given and the conclusions have been drawn.
