Internal and external network data isolation and transmission method based on two-dimensional code image recognition technology

Abstract

The invention belongs to the technical field of data real-time transmission based on the two-dimensional code image recognition technology in an internal and external network data isolation environment, and particularly relates to an internal and external network data isolation and transmission method based on the two-dimensional code image recognition technology. The invention provides an internal and external network data isolation and transmission method based on a two-dimensional code image recognition technology. The method comprises an intranet two-dimensional code data synchronization program and an extranet two-dimensional code data synchronization program, and is characterized in that the intranet two-dimensional code data synchronization program comprises a data extraction program, and the data extraction process of the data extraction program comprises the steps: obtaining incremental data from a database, and enabling each record of the incremental data to be generated into an original character string; compressing the original character string to form a compressed character string, encrypting the data, finally generating a two-dimensional code, and generating a unique code of the data when the two-dimensional code is generated.

Description

technical field [0001] The invention belongs to the technical field of real-time data transmission based on two-dimensional code image recognition technology under the environment of data isolation between internal and external networks, and in particular relates to a data isolation and transmission method for internal and external networks based on two-dimensional code image recognition technology. Background technique [0002] Nowadays, enterprises and institutions such as government departments and electric power departments will form multiple physical network environments due to security guarantees and business needs. These physical network environments will form logical or physical isolation, which is naturally unfriendly to data cross-network transmission. Especially physical isolation. However, in real business needs, there will always be business systems that require data in multiple network environments, which will form the need to transmit data across networks. Log...

However, in real business needs, there will always be business systems that require data in multiple network environments, which will form the need to transmit data across networks. Logically isolated networks can be implemented through gatekeepers, while physically isolated networks used to be only It can be carried out through purely manual modes such as burning disks, which requires a lot of manual participation, and will also cause a lot of waste of physical costs, and the real-time performance is very poor, which often cannot guarantee the needs of business systems
