A Method of LSB substitution based on image blocks and maximum entropy


Mohamed Radouane, Idrissi Nadia, Messoussi Rochdi, Roukhe Ahmed and Boujiha Tarik

In this paper we introduce an algorithm of digital watermarking based on embedding watermark into sub images with LSB technique. The watermark is embedded into specifics blocks of the host image, the selection of blocks are based on entropy value. The simulation results show that the visual quality of the watermarked image and the extracted watermark is good, this result is presented and proved by a high PSNR value.

Keywords: Information security, digital image watermarking, Entropy, Least Significant Bit (LSB), Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR).
