Embodiment 1

[0055] In the prior art, in addition to realizing the two basic functions of identifying the signer and indicating the signer's approval of the content of the electronic signature, the electronic signature system generally needs to implement: specifying the signed document; specifying the signer, and the order of the signer's signature. ; Specify the location of the signature; specify the type of signature, such as abbreviated signature, full signature; specify which fields need to be filled in before the signature and other functions, and the existing method is to define a set of additional data structures to describe the above functional data, so as to To form an envelope, if we define the above data based on the PDF document itself, there is no need to create additional envelopes in the electronic signature system, and the electronic signature function can be simplified:

[0056] (1) The document to be signed is the PDF document we are reading and editing in the PDF editor; ...

Embodiment 2

[0131] In yet another embodiment, the present invention also provides a PDF document-based system for simplifying the electronic signature process, and the system can execute or implement the electronic signature method as given in Embodiment 1. In the specific implementation, the system can be set as follows:

[0132] A form extension module for creating standard PDF form fields and extending the standard PDF form fields;

[0133] The client module is used for the initiator to edit the PDF document, write the initiator information in the PDF document, create the PDF signature field and form field, specify the signer and write the signer information in the PDF document, specify the signature sequence, and Write signature sequence information in PDF documents; and

[0134] It is used to determine the signature fields and signature sequence that the signer needs to process, and for the signer to sign and fill in the form, generate the corresponding document abstract, an...

Abstract

The invention provides a method, system and device for simplifying the electronic signature process based on PDF documents. The system includes: a form extension module, which is used to create a standard PDF form field and expand the standard PDF form field. The client module is used for the initiator to edit the PDF document, write the initiator information in the PDF document, create the PDF signature field and form field, specify the signer and write the signer information in the PDF document, specify the signature order, and Write the signature sequence information in the PDF document; judge the signature field and signature sequence, generate the corresponding document summary and the document summary encrypted based on the digital certificate, generate the final signed document, and verify the validity of the signature. The server module is used for the signer and initiator to log in, obtain the signature style, perform digital certificate signature, and verify the validity of the signature. The PDF-based signature process of this solution can be as close as possible to the written signature experience, which is more concise and efficient.

Description

technical field [0001] The present invention relates to the field of document processing and electronic signature, in particular to a method and system for simplifying electronic signature process in PDF document encryption or processing. Background technique [0002] Electronic signature refers to the data contained in the data message in electronic form and attached to identify the signer's identity and indicate that the signer approves the content. In layman's terms, an electronic signature is an electronic signature of an electronic document through cryptographic technology, not just a digital image of a written signature. It is an important means of guaranteeing the data security of electronic documents. For example, electronic signatures on confidential documents or important contract documents. The electronic signature system generally adopts the PDF format document format to realize the electronic signature function. [0003] The two basic functions of electronic ...
