An Improved Reversible Data Hiding Method Using Alternative Location Map Embedment Strategy
Yan-Wei Li and Wien Hong

This study proposed an improved data embedding scheme based on the Local Variance Controlled Reversible data hiding method (LVCR) proposed by Hong and Chen in 2010. In LVCR, the location map has to be recorded in the LSBs of a set of cover pixels and the original LSBs of these cover pixels have to be embedded into the other set of cover pixels. As a result, the pure payload of the cover image may significantly be decreased when the location map is large. The proposed method adopts an alternative method to embed location map together with the secret data directly into the pre-processed cover pixels. Therefore, the number of cover pixels for carrying data bits is increased. The location map can be directly extracted from the stego image. Experimental results reveal that the proposed method offers better or equivalent stego image quality than that of LVCR under the same payload.
