Lossless Information Hiding in Images

2.7. Summary

This chapter discussed the reversible data hiding schemes in the spatial domain. We first provide an overview of the spatial domain–based schemes. Then we discussed five types of spatial domain lossless information hiding methods, i.e., the modulo addition–based scheme, DE-based schemes, histogram modification–based schemes, lossless compression–based schemes, and reversible secret sharing–based schemes. With regard to DE-based schemes, we introduce two traditional DE-based schemes, i.e., Tian's scheme and Alatter's scheme.

With regard to histogram modification–based schemes, we first introduce two traditional schemes, i.e., Ni et al.'s original scheme and Li et al.'s APD method. Then we introduce our reversible data hiding scheme ...
