Electronic document retrieval and authority control system and method based on domestic CPU (Central Processing Unit) and OS (Operating System)

Abstract

The invention discloses a domestic CPU (central processing unit) and OS (operating system)-based electronic document retrieval and authority control system and method, and relates to the technical field of big data, which is implemented by the following steps of: reading an electronic official document, and extracting a unique identifier, derivative information and included text information of the document as a data source for full-text search; cleaning and screening the extracted text information to form an index directory library, receiving a search keyword input by a user to match an index directory in the index directory library, and returning an index address, a unique identifier and derivative information; operation authority and data authority are given based on the role of a login user, so that copying, downloading and printing functions are controlled, and the range of data which the user has the right to check is controlled; and accurately matching the position information of the document according to the returned index address, and returning the document directory list. According to the method, the searched document can be quickly positioned, and meanwhile, the display range of the data is delimited based on control of authority management, so that the security of the data is ensured.

Description

technical field [0001] The invention relates to the field of big data technology, in particular to an electronic document retrieval and authority control system and method based on domestic CPU and OS. Background technique [0002] Facing the current severe international information security situation, my country is gradually strengthening the construction of information security protection, and information security is gradually becoming an important national security strategy. With the improvement of my country's scientific research technology level and the investment of a large number of scientific research forces, the hardware level continues to develop, and a number of domestic chips with independent intellectual property rights have emerged, such as Loongson, Phytium, and Kunpeng, and supporting software products, such as domestic operating systems. Winning the bid for Kirin and Tongxin UOS, domestic database Shentong, Jincang, Dameng, domestic middleware Dongfangtong, K...

Problems solved by technology

[0003] Under this background, the electronic official document system based on the domestic environment has been first used by the government and other departments. The electronic official document system will produce a large number of electronic official document documents, involving documents in various formats such as wps, et, ofd, etc., resulting in It is extremely time-consuming and laborious for users to find the required documents according to the content in the massive data

At the same time, considering the data security of the system, some electronic official documents can only be disclosed within a certain range or have a high level of confidentiality. It is necessary to ensure that the required data can be quickly and accurately found, and data security issues must also be taken into account.
