The data transmission method based on multi-network communication is applied to the first electronic equipment on the video private network side, the sequence of steps in the flow chart can be changed according to different requirements, and some steps can be omitted.
S11, the first electronic equipment obtains data to be transmitted which need to carry out multi-network interaction in the private video network.
Generally, the network topology of traffic can be divided into a video private network and a public security network, which are generally called dual networks, the communication between the dual networks needs to go through a security boundary, and the boundary implementation mode generally includes: database boundaries, File Transfer Protocol (FTP) boundaries, gatekeepers, and the like. The FTP boundary uses a file transfer mode to carry out dual-network communication.
Common working network environments have high requirements on information security levels and are divided into a video private network and a public security network, wherein important systems such as a six-in-one system, an integrated command platform, big data study and judgment analysis and the like are basically deployed in the public security network, front-end processing of pictures and videos is basically deployed in a traffic network, systems applied by people are accessed to the Internet, public numbers, small programs, microblogs, mobile phone APPs and the like are also accessed, and network payment such as payment treasure payment, WeChat payment, hundred-degree payment and the like is also required to be accessed.
The network security levels of the multiple networks are different, the network boundary generally requires physical isolation or software isolation, but the multiple networks necessarily have data interaction requirements, so that the data interaction requirements and the data security requirements exist.
In the embodiment of the invention, the multi-network interaction takes the interaction between a video private network and a public security network as an example. The data to be transmitted is, for example, a face picture captured at an intersection, and the face picture needs to be transmitted to a public security network through a video private network.
The invention can carry out safe Remote Procedure Call (pRPC) communication based on multiple networks, solve the problems of information security, cross-network interaction of service and resource waste. The pRPC is a user-defined Remote Procedure Call (RPC) and is suitable for a data interaction scene such as a traffic police video private network and a public security network. The user-defined RPC communication is used for remote communication among different networks, can be used for solving the safe transmission of video private network and public security network data and the safe calling among cross-network services, and the technology not only ensures the information safety, but also improves the timeliness of cross-network communication in the industry.
And S12, the first electronic equipment adopts a gateway technology to filter the data to be transmitted.
The data to be transmitted may carry some unnecessary data, for example, the face picture may also carry other environmental information, and the data to be transmitted may be filtered by using a gatekeeper technology.
Specifically, the gatekeeper technology can be adopted to perform SQL injection, DDOS attack and brute force cracking on the data to be transmitted, so as to filter the data to be transmitted and filter out unnecessary data.

And S13, sequentially carrying out serialization processing and encryption processing on the filtered data to be transmitted by the first electronic equipment, and then generating a first data file.
Serialization (Serialization), among other things, is the process of converting state information of an object into a form that can be stored or transmitted. During serialization, the object writes its current state to a temporary or persistent store.
In the embodiment of the present invention, object serialization processing may be performed on the filtered data to be transmitted by using Serializable of java and writeObject of ObjectOutputStream.
Further, the serialized bytecode may be encrypted using an asymmetric encryption key, for example, using an RSA encryption and decryption algorithm to generate the first data file.
And S14, the first electronic equipment transmits the data processing request carrying the first data file to second electronic equipment on one side of the public security network by adopting user-defined Remote Procedure Call (RPC) communication.
The design principle of the data exchange technology is to use space to exchange security, and a buffer area is established between two networks to ensure that traffic is in a controllable range, so that the data exchange technology is a current safer technical means.
In the embodiment of the invention, the first electronic device transmits the data processing request carrying the first data file to the second electronic device on one side of the public security network through a boundary system (such as an FTP boundary) by adopting a data exchange network technology through a video private network, so that the safety of data transmission can be ensured.
The Remote Procedure Call (RPC) communication is a safe Remote Procedure Call (pRPC), and the pRPC is a self-defined Remote Procedure Call (RPC) and is suitable for data interaction scenes such as traffic police video private networks and public security networks.

acquiring the current network transmission bandwidth;
inputting the network transmission bandwidth and the size of the first data file into a time calculation model to obtain transmission time;
and if the transmission time is less than the preset time, transmitting the data processing request carrying the first data file to second electronic equipment on one side of the public security network by using user-defined Remote Procedure Call (RPC) communication.
In this optional implementation, network transmission bandwidths in different time periods are different, and are sometimes in a busy stage and sometimes in an idle state, if the network is in the busy stage, data transmission is slow, and even packet loss occurs, and if the network is in the idle state, data transmission is fast, and user experience is good.
In order to maintain the efficiency of data transmission, the current network transmission bandwidth can be obtained in real time, and the network transmission bandwidth and the size of the first data file are input into a time calculation model to obtain transmission time; if the transmission time is less than the preset time, the current network transmission bandwidth is fast, and data can be transmitted rapidly, so that a user-defined Remote Procedure Call (RPC) communication can be adopted, and a data processing request carrying the first data file is transmitted to second electronic equipment on one side of a public security network. The preset time may be a minimum transmission time that may be allowed by a user.
The time calculation model can be trained in advance, specifically, a plurality of network transmission bandwidths, data files and transmission times can be obtained, the network transmission bandwidths, the data files and the transmission times are learned, the relationship among the network transmission bandwidths, the data files and the transmission times is determined, and the time calculation model is generated.
And S15, the first electronic equipment adopts the user-defined RPC communication to receive a second data file returned by the second electronic equipment through the public security network after processing the first data file.
After the first electronic device transmits the first data file to the second electronic device, the second electronic device may process the first data file according to the data processing request and return the first data file through the public security network. For example, the first data file is a face data file, the second electronic device may identify a face image in the face data file to obtain a face identification result (such as a name, an address, and identity information of a user to which the face belongs), and generate the second data file according to the face identification result to return to the first electronic device.
Specifically, the first electronic device may adopt the customized RPC communication, and receive, at a boundary system (e.g., FTP boundary), a second data file returned by the second electronic device through the public security network after processing the first data file by using a data exchange network technology.
The whole data transmission process of the video private network and the public security network adopts a data interaction network technology, so that the safety of data transmission can be ensured.
The Remote Procedure Call (RPC) communication is a safe Remote Procedure Call (pRPC), and the pRPC is a self-defined Remote Procedure Call (RPC) and is suitable for data interaction scenes such as traffic police video private networks and public security networks.
Therefore, the RPC communication is called through a self-defined remote procedure, so that the data transmission service among multiple networks is simplified, and the responsibility of data interaction is reduced.
And S16, the first electronic equipment adopts the gatekeeper technology to decrypt and deserialize the second data file.
The first electronic device further needs to adopt the gatekeeper technology to perform decryption processing, deserialization processing, and sensitive information anti-falling detection processing on the second data file to obtain a final data file.
Wherein the decryption process is relative to the encryption process, and the deserialization process is relative to the serialization process.
And S17, the first electronic equipment carries out sensitive information anti-falling detection processing on the processed second data file to obtain a final data file.
In order to reduce the risk of sensitive information leakage, the second data file after processing needs to be subjected to sensitive information anti-falling detection processing, that is, sensitive words in the second data file are removed, such as sensitive data of user names, identity cards, license plates of motor vehicles and the like
In the invention, a security algorithm and a three-network communication mode are designed by combining a network gate technology and a data exchange technology, and the method mainly aims at solving the problems that the complexity of service system data exchange is increased and the time delay is increased due to the setting of network security.
Specifically, the performing of the sensitive information anti-falling detection processing on the processed second data file to obtain the final data file includes:
acquiring a plurality of preset keywords;
inputting the preset keywords into a pre-trained word generation model to obtain a plurality of standby keywords;
forming desensitization keywords according to the preset keywords and the standby keywords;
and deleting the content matched with the desensitization keywords from the processed second data file to obtain a final data file.
In this alternative embodiment, a word generation model may be trained in advance, and the word generation model may be used to generate a plurality of alternative words having the same or similar meaning as the input word, such as inputting a name, outputting a name, and the like. Through the word generation model, a plurality of standby keywords with the same or similar meanings as texts of a plurality of preset keywords can be generated, and the defect of insufficient preset keywords is overcome, so that sensitive information anti-falling detection processing can be performed on the processed second data file to the maximum extent, and more sensitive information is deleted, and leakage of the sensitive information is avoided.
In the method flow described in fig. 1, the first electronic device and the second electronic device may use a user-defined remote procedure call RPC communication to perform data transmission between multiple networks, thereby ensuring real-time synchronization of data and increasing convenience of service data interaction, and simultaneously, an encryption processing and desensitization processing manner on sensitive data are also used, thereby further increasing data security, reducing the risk of sensitive information leakage, reducing complexity of multi-network data interaction, and reducing multi-network data interaction delay.
