Abstract :
To address the defect of the simplex digital signature in e-commerce and e-government, the paper presents a method of electronic seal based on the digital watermark technology. The method combines one-way hash function and digital watermarking, implements the tamper-proofing of electronic documents, anti-copy of e-seal and secure access control function, can effectively to meet the basic needs of electronic document and security requirements. This paper shows experimental results and the future direction of development.
