Abstract: The electronic seal becomes more and more important in the domain of E-government and E-commerce, and the solution for electric seal based on digital signature and digital watermark is still in developing. Following the Domino-PDF-DSA technique path, this paper synthesizes the technology for PDF digital signature and Lotus platform PKI, successfully makes second-exploiter in virtue of Notes C API and PDF API, extends the Notes ID file with electric seal image, and implements an application system which embedded electric seal into PDF file on Lotus platform.
