Abstract:In this paper, we propose a simple and efficient reversible information-hiding scheme for VQ index tables. One secret bit can be embedded into one index pair if this pair passes the predefined restriction. Even if the index pair does not pass the test, it can still carry one secret bit if an additional indicator ( a preserved index value) is attached. The experimental results show that our proposed schemes can accomplish lossless recovery of VQ index tables, and the hiding capacity is satisfactory.
