Abstract

For any watermarking system, there are two important requirements which are quality and robustness. These two requirements are conflicts all the time, which means when increasing image quality the robustness will decreasing and vice versa. This study focuses on the robustness after applied chosen attacks for the watermarked image based on the existing technique Dual Intermediate Significant Bit (DISB). This method requires embedding two bits into every pixel of the original image, while and the other six bits are changed so as to directly assimilate the original pixel. In the case, when the two hidden bits are equal or not equal to the original bits, there is a need to use mathematical equations to solve this problem. Two measurements criteria used in this study to test image robustness, the first one is Normalized Cross Correlation (NCC) and Bit Error Ratio (BER). The results show that the proposed model produces robustness watermarked images as compared to our previous method when focuses on the high quality of the watermarked image.
