| Abstract: | Through using Property of DCT intermediate coefficients approximately equal to zero, this paper proposes a 2-bit image watermarking embedding algorithm on block DCT intermediate coefficient. The cover image is not needed when extracting watermarking data. The experimental results show that the alporithn has good robustess on conventinal image processing. |
