Problems solved by technology
The more information the QR code itself has, the more pixels it needs; the more pixels it has, the more difficult it is to distinguish and decode, because the scanning device (camera) has an upper resolution limit.
Also, if you want to display a QR code on the screen, and use a general camera for scanning code recognition, it is limited by the resolution of these hardware

Embodiment 1
[0024] Embodiment 1. In this embodiment, the first network is the A network, and the second network is the B network.
[0025] Such as figure 1 and figure 2 As shown, the present invention includes a data duplex mutual transmission method based on security graph identification, the method is based on a client or server, a data server, a boundary security graph output device and a boundary security graph input device in two border-isolated networks Achieved.
[0026] The transmission of the data based on the security graph by the first network to the second network specifically includes the following steps:
[0027] 1. The client or server system in network A transmits the data to be transmitted to network B to the data server of network A;
[0028] 2. The original data MsgAtoB to be sent out by the data server of network A is first encrypted by RSA to obtain MsgAtoB_Encryption, sorted according to the principle of first-in-first-out, and each original data is disassembled ...

The invention discloses a data duplex mutual transmission apparatus based on security map identification. The apparatus comprises clients or servers, data servers, boundary security map output devices and boundary security map input devices in two networks with isolated boundaries, the clients or servers in the networks are connected with the data servers, and the data servers are separately connected with the boundary security map output devices and the boundary security map input devices, wherein the boundary security map output device of the first network corresponds to the boundary security map input device of the second network, and the boundary security map output device of the second network corresponds to the boundary security map input device of the first network. The data duplex mutual transmission apparatus disclosed by the invention realizes data duplex mutual transmission of the two networks with isolated boundaries; and in addition, the security protection of data transmission is improved by encryption and decryption, and the efficiency and accuracy of the data transmission are provided by a manner of matching a plurality of split groups.
Description
technical field [0001] The invention relates to the technical field of data transmission between networks, in particular to a data duplex mutual transmission device based on security graph identification. Background technique [0002] At present, the technology of two-dimensional code has been widely used in production and life. Two-dimensional bar code / two-dimensional bar code (2-dimensional bar code) records data symbol information with a specific geometric figure distributed in a plane (two-dimensional direction) according to certain rules; Using the concepts of "0" and "1" bit streams that constitute the logical basis of the computer, using several geometric shapes corresponding to binary to represent text and numerical information, automatic reading through image input equipment or photoelectric scanning equipment to achieve Automatic processing of information: it has some common features of barcode technology: each code system has its specific character set; each char...
