Embodiment Construction

[0029] The purpose and effects of the present invention will become more apparent by describing the present invention in detail below in conjunction with the accompanying drawings.

[0030] The present invention is based on the QR code-based physical isolation data exchange method for internal and external networks. The process of data exchange from the internal network to the external network is as follows: figure 1 shown, including the following steps:

[0031] Step 1: Extract the data to be exchanged from the intranet database, encode the data, and generate multiple QR code images, which are regularly arranged in the form of a QR code matrix and displayed on the display screen of the intranet system terminal device.

[0032] The terminal equipment of the intranet system can be implemented by an ordinary PC, which is required to be able to connect to the intranet, has an LCD display with backlight, has a camera function, and can clearly display two-dimensional codes.

Abstract

The invention discloses an intranet-extranet physical isolation data exchange method based on QR (quick response) code. The method of exchanging data from an intranet to an extranet includes: firstly, extracting data to be exchanged in an intranet database, encoding the data to generate a plurality of QR code images, and regularly arranging and displaying the images on a display screen of intranet system terminal equipment in a form of QR code matrix; secondly, using a camera of extranet system terminal equipment to acquire the matrix-type irregularly arranged QR code images displayed on the display screen of the intranet system terminal equipment; and thirdly decoding acquired QR code sequences by parallel algorithm on the extranet system terminal equipment so as to obtain exchanged data. The method has the advantages that such defects as high precise and need for labor in existing traditional exchange methods of gateway copying or USB (universal serial bus) flash drive copying, the method is high in reliability, high in safety and low in operation and maintenance cost, exchange time is shortened, and efficiency in intranet-extranet data exchange is improved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a two-dimensional code-based physical isolation data exchange method for internal and external networks. Background technique [0002] With the development of society, more and more attention has been paid to the informatization construction of various industries. In the process of informatization construction, for security reasons, government or enterprise networks often require the isolation of internal and external networks, but the exchange of external data is unavoidable and very important. The traditional method is to use the gatekeeper for data exchange, although this can improve automation, but the construction cost is relatively high; and the way of generating intermediate files or copying them with a USB flash drive greatly reduces work efficiency, especially when real-time data is required In the case of exchange, it will affect the normal ope...
