摘要

This paper overviews image watermarking tech- niques and their integration into protection systems. It is shown how that technology can solve the problems of waveform authentication as well as those related to tra- cing of digital copies. Image processing techniques and the communication system of watermarking are briefly presented. Some challenges approach to the watermar- king field are enumerated in the conclusion.
