A High Capacity Robust Lossless Data Hiding Scheme Using Complementary Embedding Strategy

This paper proposes a high capacity robust lossless data embedding scheme with great payload capacity, good image quality and acceptable robustness, which is based on adjacent pixel difference (APD) and histogram distribution constrained (HDC) technique. The main scenario behind our technique is that we use neighbour pixels that often are highly correlated and have spatial redundancy. The secret data is embedded based on a multi-level histogram shifting mechanism and shifting the arithmetic difference values of blocks in two steps of embedding strategy. In the decoder, if we receive embedding level (EL) via channel, cover image and secret content can be recovered bit–by–bit. According to the results obtained, the proposed scheme cannot only hide a large amount of information in a host image without making noticeable distortion, but also can pull off against unintentional attacks such as JPEG compression.
