Web resources protection is one of the most difficult problems on network. Many solutions relevant have been put forward and some protecting systems have come out until now. However, almost all solutions are based on the method that compares with files' digital signature firstly and judges files have been tampered with or not secondly [1]. And all these solutions are useless for resolving misusing web resources. This paper puts forward a new solution that combines digital watermarking and digital signature to monitor and protect web resources, which can not only prevent to tamper with web resources but also can protect copyrights of important resources.
