To protect the copyright of digital documental images,a new documental image copyright protection scheme is proposed.The invertible visible watermark is used to achieve the balance between documental resources share and copyright protection.At the same time,a digital fingerprint sequence dependent of user information is used to trace traitors.Experiment results demonstrate the proposed scheme has high visual quality of watermarked images and good watermark visibility,and it can be applicable to copyright protection of documental images.
