Abstract :
Lossless data hiding is the act of hiding some secret information into a cover data in such a way that after extraction of the hidden data, the cover data can be recovered bit-by-bit. In this paper we propose a novel method of lossless data hiding for halftone color images. Halftone images are widely used in the printing and publishing industries. Digital rights management of such images is an important issue. The proposed method can embed information in the form of a binary bit sequence into halftone color images with negligible change in their perceptual quality, as well as recover the unmodified original cover image after the hidden information has been extracted. The proposed method can be applied in reversible watermarking and steganography for authentication and content protection of colored halftone images.
