Digital fingerprinting is a special digital watermarking technology that can deter legal user to redistribute multimedia content to others. With traitor tracing, it can detect illegal users who use multimedia content illegally. However, collusion attack can avoid some illegal users being detected. With different fingerprinted copies, collusion attack can produce a new colluded fingerprinted copy for get rid of the fingerprint information from the colluded copy, so digital fingerprinting technique should deter collusion attacks. In order to improve the performance of new digital fingerprinting technique in future, this paper presents a new collusion attack approach based on interpolation. The proposed interpolation collusion attack scheme comes from the idea of image fusion. The experimental results demonstrate that the proposed interpolation collusion attack method outperform average attack and maximum attack.
