Reversible digital image hiding based on multilevel histogram modification and halftoning technique

This paper presents a novel image hiding method based on multilevel histogram modification and halftoning technique. We use a multilevel histogram modification to finish the data embedding and extracting. The halftone data is extracted from stego-image, and secret image is achieved from LUT inverse halfton technique. Experimental results show that our method provides high capacity of digital image embedding while keeping the distortions at a low level.
