A Data-reversible Hiding Algorithm in WSNs
Journal of Networks, 2013 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.

A reversible data hiding method for encrypted images [PDF]
SPIE Proceedings, 2008 Since several years, the protection of multimedia data is becoming very important. The protection of this multimedia data can be done with encryption or data hiding algorithms. To decrease the transmission time, the data compression is necessary. Since few years, a new problem is trying to combine in a single step, compression, encryption and data ...

A general pixel mapping based reversible data hiding in encrypted images
Journal of King Saud University: Computer and Information SciencesReversible data hiding in encrypted images enables secure data embedding while preserving content privacy. However, existing pixel-mapping-based reversible data hiding in encrypted images methods, such as Manikandan and Zhang’s method, produce blurry ...
