To solve the problem of multiple users sealing the electronic document,a multi-user digital seal system with digital multi-signature based on RSA is designed.After the idea of digital multi-signature is introduced,the system framework and the system architecture are presented.Digital watermarking is used to protect cachet image from being copied and forged,at the same time to keep the uniqueness.An eKey is used to store the cachet image and some key for improving the system safety.An ActiveX control is used as carrier to store digital cachet and signature information for keeping the structure of document.Result of experiment indicates that the system has stronger safety and practical.
