摘要

This paper, proposes a method that by generating a pseudo random pattern, which will work as the watermark and the watermark is embedded during the quantization procedure. Then WSR (watermarking survival rate) is used to search for the optimized truncation points by running the EBCOT process, the truncation point is adjusted to stay at the bit plane boundary and it is used as the dividing point to split magnitude bits of wavelet coefficients, which is then sent to EBCOT for encoding. The final output is the J2K coded watermarked image. The results show that watermarked EBCOT image is nearly rate-distortion optimized, the decoder can recover the original image, the watermark can be detected effectively, and it is robust against geometric attacking such as rotating attack, cropping and scaling attack.
