摘要
Abstract
Digital fingerprinting is a technology which can protect the multimedia content from illegal use by unauthorized users.Collusion attack is an effective attack with digital fingerprinting where several copies with the same content but different fingerprints are combined to remove the original fingerprints.This paper proposes a new nonlinear collusion attack method based on the independent Gaussian fingerprint.The maximum value,the minimum value and the average value are chosen from every position of the fingerprints by colluders.A new illegal copy is built by the sum of maximum value and minimum value subtracted the average value.The result shows that the attack performance is more effective than other methods under the same perceptual condition.关键词
