With the popularization of Internet and the development of multimedia techniques,digital multimedia has become the main means of information communication.Digital watermark is a new technology which can protect copyright and authentication source.This paper proposes a new image watermarking scheme in order to solve the contradiction between imperceptibility and robustness.Experiment results indicate that this method is very robust against the common signal processing attacks such as JPEG compression,filtering,noise contamination,cropping.
