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