A Data-reversible Hiding Algorithm in WSNs

In view of the phenomenon that data-hiding algorithm is easy to be detected by inspecting tool SPAM when carrying information, random insertion and histogram modification are adapted in the data hiding. A data-reversible hiding algorithm in WSNs is put forward. By collecting and referring sub-graph, calculating data fusion algorithm that can protect the data’s completion and privacy and analyzing the reversible hiding data algorithm research, the inspection of SPAM. Finally MATLAB7.0 exploitation is adopted to stimulate the analysis of experiment. The result shows that compared with Kim algorithm, the algorithm is safer to prevent the SPAM inspection and is more suitable for information transfer.
