Problems solved by technology

[0004] Basically, you can only use the same software to exchange files between different people, but you cannot exchange files between different software, forming an information closure
[0005] 2) It is difficult to extract document information
[0007] 3) The access interface is not uniform, data compatibility is difficult or the cost is too high
[0009] 4) Poor information security
[0011] 5) It is all for the processing of a single document, lack of multi-document management means
Therefore, setting document storage standards will affect the portability and scalability of the system
[0023] 7) The technology of page layering is not perfect
[0046] K=kG[Wherein K, G is the point on Ep(a, b), k is an integer less than n (n is the order of point G), it is not difficult to find that given k and G, according to the addition rule, calculate K It is easy; but given K and G, it is quite difficult to find k

Embodiment approach

[0796] A role consists of a unique ID number and a pair of unique PKI keys, but only its ID number and public key are stored in the role object, and the private key is mastered by the application software. The ID number can be any number or character string, as long as different roles are assigned different IDs. The PKI algorithm can be one of ECC and RSA.

[0797] The security management function is composed of a role management unit, a secure session channel unit, an identity authentication unit, an access control unit, and a signature unit.

[0798] The whole process of logging in with a certain role (or multiple roles), performing a series of operations, and finally logging out is called a session. A session includes a session flag, a list of login roles. Sessions can be conducted over a secure session channel. A secure session channel has a session key that is used to encrypt data passed between the two parties. Asymmetric keys can be used as session keys, but symmetr...

Abstract

The invention provides a document processing system and method. And the system comprises document library system, memory, and application software, where the data of the document library are stored in the memory, the document library system and the application software are interconnected through a standard calling interface, and the standard calling interface is defined according to the predefined actions and objects; the operations of the application software on documents are all united into operations on a predefined universal document model and the application software sends out instructions through the standard calling interface to the document library system, and the document library system executes corresponding operations on the document library stored in the memory according to the instructions.

Description

technical field [0001] The present invention relates to a system and method for processing documents, and in particular to a document processing system and method. interoperability. Background technique [0002] At present, software related to various unstructured documents has been relatively popular, and a variety of document formats have formed. For example, a content management software often has to deal with two or three hundred document formats, and these formats are constantly being updated, which brings great difficulties to software developers. How to solve the commonality of documents, digital content extraction, and format compatibility has become more and more people's attention, and people are eager to solve the following problems: [0003] 1) Documentation is not universal [0004] Basically, you can only use the same software to exchange files between different people, but you cannot exchange files between different software, forming information closure. ...
