In accordance with collusion attack, a digital fingerprinting scheme of digital images is studied and proposed by this paper. Different binary chaotic sequences produced by Logistic chaotic map and by means of setting different initialization are chosen to act as digital fingerprints of the protected digital images. Drawing lessons from some effective feasible digital watermarking algorithms, and fully giving consideration to the robustness, the imperceptibility and the ability against the collusion attack of the digital fingerprinting scheme, blind embedding and extracting algorithms are studied and utilized to embed and extract digital fingerprints. The working performance of the digital fingerprinting scheme is tested and evaluated. Digital fingerprinting embedding doesn't affect the visual quality of the original digital image. The digital fingerprinting scheme has the basic ability resisting collusion attack.
