This paper describes a robust watermarking algorithm and a collusion-secure fingerprinting scheme based on it. Watermarking robustness is obtained by using the JPEG algorithm to decide mark location and magnitude; the proposed algorithm supports multiple marking. The properties of dual binary Hamming codes are exploited to obtain a fingerprinting scheme secure against collusion of two buyers. The fingerprinting construction proposed here is simpler than previous collusion-secure proposals.
