Problems solved by technology

The implementation cost of this method is very high, and the data center needs to normalize the heterogeneous data, and also needs the support of the central database and storage devices
Secondly, the data consistency is not good, and the data in the data center does not necessarily reflect the real-time changes of the data
In addition, since the data is stored centrally in the data center, once the server is compromised, a large amount of data will be leaked

Embodiment 1

[0045] This embodiment is a PDF signature document interconnection system, including four components: a document provider, a document user, a document owner, and a security agent. See figure 1 , the functions of each part are:

[0046] The document user is the party who has the need to use the document;

[0047] The document provider generates and saves the document object, and is responsible for the access control of the document, that is, to decide whether to allow the response to the request of the document user. In real life, the generation, preservation and ownership of documents are not uniform. In other words, documents are not generated and kept by their owners;

[0048] The document owner is the actual owner of the document and has the right to decide the disposal of the document and its contents. The document provider or user can transmit or use the document only with the owner's consent and authorization.

[0049] The security agent is the security middleware in t...

Embodiment 2

[0057] This embodiment is a method for interconnecting and interoperating PDF signature documents using the system of Embodiment 1, such as image 3 The specific process is as follows:

[0058] S1. When the document user needs to use the PDF document belonging to the owner but stored in the document provider (for example, the pharmacy needs to view the electronic prescription issued by the patient in the hospital), first generate a PDF document request R, and send the time to the security agent Stamp server request timestamp T R , then use the private key to pair R and T R Sign and get the signature value S U (R||T R ).

[0059] Among them, the content of R includes the request scope (such as "municipal hospital"), the object type (such as "electronic prescription") and the owner (such as "Li Jian"), and the form of R is a key / value pair (such as "hospital") = Municipal Second Hospital & Name = Li Jian & Data Type = Prescription Form") or a combination of keywords (such a...

Abstract

The present invention discloses a method and system for intercommunicating secure PDF signed documents, wherein the system includes: a document user who submits a PDF document use request; a document provider who generates and saves a PDF document object and decides whether to allow a response to the document user PDF document usage request; the document owner has the right to decide on the disposal of the PDF document and its contents, and the document provider or document user can only transmit or use the PDF document with the consent and authorization of the document owner; security agent , which is responsible for parsing, routing and transmitting requests for PDF documents. The invention realizes the secure interconnection and intercommunication of PDF signed documents between heterogeneous business systems, including identity authentication before document access, document retrieval prevention of repudiation, data encryption during document transmission and the like. The invention improves the security of PDF signature document transfer, and reduces the risk of document data loss caused by unsafe access and transfer.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a secure PDF signature document interconnection and intercommunication method. Background technique [0002] As society gradually enters the digital age, we encounter more and more various PDF electronic signature documents (such as electronic invoices, electronic insurance policies, electronic prescriptions, etc.) in our lives. The appearance of these electronic signature documents has brought great convenience to our production and life, and has many advantages, such as convenient storage, low cost, no need to print, and not easy to lose. [0003] But at present, these documents are still scattered in the systems of different business units, such as the inspection report is kept in the hospital, the electronic insurance policy is in the insurance company and so on. There is no document interconnection between the business systems of various units, which inevitabl...
