A COMBINATION OF REVERSIBLE DATA HIDING AND MEDICAL IMAGE COMPRESSION

S. Lakshmanan

Abstract


In this paper, a new lossless reversible data hiding technique is presented coupled with compression. Medical images, different from other images, require additional care when embedding other information inside them because the additional information should not change the image quality and readability. Lossless data hiding techniques are used for overcome any misdiagnose caused by embedding data into medical images. In this paper, proposed a lossless reversible data hiding. The proposed technique implements a pure lossless reversible data hiding scheme. It can be used to hide patient's information hiding at boundary of Region of Interest (ROI) in medical images. Run Length Encoding is used for compression. It has recovery facility without any loss of information. The experimental results show that the host image and hidden information can be exactly retrieved from the Stego image.

Keywords: Reversible data hiding, Medical image compression, RLE
