Abstract: Provided is an enterprise user-based method and system for a simplified PDF document electronic signature. The method comprises: an electronic signature system is configured to link up with an enterprise account system, such that an enterprise user automatically logs in to the electronic signature system of a server after logging in to an operating system; a signature style is created and signing is carried out by using a client; and the server performs digital certificate encryption on a signed document summary, and on the basis of the foregoing, a final PDF document is generated on the client. In the solution of the present invention, by linking up an enterprise account and a signature system, an electronic signature process of a PDF document may be greatly simplified, the signing experience of an enterprise user is as close as possible to a written signing experience, and the present invention is simple and efficient.

Abstract: A system for simplifying an electronic signature process on the basis of a PDF document includes a form extension module for creating a standard PDF form field, and extending the standard PDF form field; a client module, used by an initiator to edit a PDF document, and used for writing initiator information in the PDF document, creating a PDF signature field and a PDF form field, designating a signer and writing signer information in the PDF document, designating a signature order and writing signature order information in the PDF document, determining the signature field and the signature order, generating a corresponding document summary and a document summary encrypted on the basis of a digital certificate, generating a final signed document, and verifying the validity of the signature; and a server module, used by the signer and initiator to log in, and for acquiring a signature style, signing a digital certificate, and verifying the validity of the signature.
