A blind binary image digital watermarking algorithm is proposed in the DCT domain. The algorithm uses the correlativity of the inter-blocks DC components based on blocked DCT with binary image. No original binary image is needed when detecting the watermark. The algorithm is realized with the efficient and practical programming tools MATLAB, The effect of the corresponding parameters is analyzed in detail.
