Two-dimensional code encryption transmission method and system

Abstract

The present invention provides a two-dimensional code encryption transmission method and system. The method comprises the steps of (S1) the encryption module of a data input client encrypts data to be transmitted, forms an encrypted string and transmits the encrypted string to a two-dimensional code generation module, (S2) after the two-dimensional code generation module receives the encrypted string, encryption key and ciphertext, a two-dimensional code is generated and is displayed through a two-dimensional code display module, (S3) the scanning module of a data receiving client scans the two-dimensional code and analyzes the two-dimensional code into an encrypted string and transmits the encrypted string to a decryption input module, and (S4) the decryption input module decrypts the encrypted string and writes the decrypted two-dimensional code data into the database of a receiving client. According to the two-dimensional code encryption transmission method and system, the two-dimensional code is used for the transmission of few encryption information, and through the encryption of the two-dimensional code data, the real-time data synchronization of an internetwork application system database of internal and external physical isolation is realized.

Description

technical field [0001] The invention relates to the field of communication, in particular to a two-dimensional code encrypted transmission method and system. Background technique [0002] At present, there are a large number of secret-related units in our country. The internal networks of secret-related units are physically isolated from the Internet, and data synchronization and real-time transmission cannot be achieved. Current solutions often use two means to transfer information: [0003] Method 1: Copy the data manually by burning the disc. Export the data generated by the internal and external network regularly through software every day, and burn it into a CD, and then import the data through the data import program of the internal and external network; [0004] Method 2: Use gatekeepers and isolation devices to implement timing import between data. The internal and external networks are connected through the gatekeeper, and the gatekeeper device is usually turned ...

Problems solved by technology

[0005] The above two data synchronization methods are slow in operation, and the running business system needs to be stopped before its database can be backed up and synchronized. This operation is time-consuming and laborious, and it is easy to cause data loss.

At the same time, regardless of the use of gatekeepers, isolators, or CD recording methods, the synchronization efficiency is low and the synchronization speed is too slow. Therefore, it is not possible to quickly synchronize a small amount of information between internal and external network software and perform joint processing in real time. Good development, which has created a big bottleneck for the work and business processing of secret-related units
