Abstract
This paper presents an image watermarking method where partial embedding approach is implemented in order to avoid interference from other nearby watermark bits. With cautious selection of watermark embedding positions, the maximum number of embedding bits can also be achieved. Precisely, the embedding positions are pseudo-randomly selected from the blue component of the host color image in accordance with a secret key, while the watermark extraction is blindly achieved by using pixels around the embedding bit in the same position and sequence used in the embedding process. The experimental results verify the better performance in term of accuracy of the extracted watermark compared to the previous related work [3]. ฉ 2014 Asia-Pacific Signal and Information Processing Ass.
