Referring to fig. 1 and fig. 1a, fig. 1 is a schematic flowchart of a video backtracking method provided in an embodiment of the present application, and fig. 1a is a schematic scene diagram of the video backtracking method in an embodiment of the present application. The video backtracking method is applied to the processing server 10. After detecting a screen recording trigger request sent by a user, the processing server 10 may control the client 20 to record a screen, specifically may control the client 20 to continuously collect DOM node information and click events, compress the collected DOM node information and click events at intervals of a preset time to obtain a compressed packet, decompress the compressed packet transmitted through the data receiving server 30 and the asynchronous system 40 by the processing server 10, and generate intermediate video data according to time assembly and the like. According to the method and the device for processing the video, the video recorded by the client can be comprehensively and rapidly restored through processing of related video data, meanwhile, the operation of a user on an application program is not affected, the method and the device can be applied to scenes such as smart government affairs, so that construction of smart cities is promoted, and the use experience of the user is improved. The individual steps of the video backtracking method will be described in detail below in terms of the processing server 10.
Referring to fig. 1, fig. 1 is a schematic flowchart of a video backtracking method according to an embodiment of the present invention. The method can be operated in terminals such as smart phones (such as Android mobile phones and IOS mobile phones), tablet computers, notebook computers and intelligent devices. As shown in fig. 1, the steps of the method include steps S101 to S104.
Step S101, if a screen recording trigger request sent by a user is detected, controlling a client to record a screen according to the screen recording trigger request so as to obtain a plurality of DOM node information including time stamps and a plurality of click events; the screen recording triggering request comprises user mark information.
In this embodiment, if the processor server detects a screen recording trigger request sent by the user, the processor server may control the client to record a screen according to the screen recording trigger request. Several DOM node information including a time stamp may be obtained during the recording process. Wherein, DOM node means that each component in XML file is a node, DOM node information means information included in DOM node. When a user clicks the client, the cursor moves from one DOM node to the adjacent DOM node to form an event.
For example, when a user logs in the insurance system at the client, that is, the user completes logging in by inputting an account number and a password, a screen recording trigger request is correspondingly generated at the moment, so that all operation traces performed by the user on the client are recorded, and video backtracking is facilitated. Since the recording process is a continuous process, when the DOM node is acquired, the corresponding time stamp needs to be determined at the same time, so that the subsequent correct backtracking can be performed.
Further, as shown in fig. 2, the step S101 includes steps S201 to S202.
Step S201, if a screen recording trigger request sent by a user is detected, the screen recording trigger request is analyzed to obtain user mark information and a screen recording instruction.
After detecting a screen recording trigger request sent by a user, the processing server can analyze the screen recording trigger request, so that user mark information and a corresponding screen recording instruction are obtained. The user identification information can be an account number of the user, and can be other information capable of confirming the identity of the user.
Step S202, the screen recording instruction is sent to the client to control the client to continuously collect DOM node information and clicking events, and the collected DOM node information and clicking events are stored in a temporary storage unit, wherein each DOM node information and each clicking event comprise a time stamp.
The processing server can send the screen recording instruction to the client, and generally, after receiving the screen recording instruction, the client can be controlled to continuously collect DOM node information and click events, so that recording of a screen can be realized in real time. Meanwhile, the processing server also controls the client to store the collected DOM node information and the clicking event into the temporary storage unit. Each DOM node information and each click event comprises a time stamp so as to realize the subsequent backtracking of the video.
Step S102, the control client performs association compression between user mark information in the screen recording trigger request, the obtained DOM node information and the clicking event at intervals of preset time to obtain a compression packet, and sends the compression packet to the data receiving server.
In this embodiment, the processing server may control the client to correlate the user mark information in the screen recording trigger request with the DOM node information in the temporary storage unit and the click event every preset time. After the association is completed, the DOM node information and the click event are compressed to obtain a compressed packet, and the compressed packet is sent to the data receiving server. The compressed DOM node information and the click event can effectively reduce the network transmission load of the client in the transmission process, and the transmission efficiency is improved.
And step S103, if yes, controlling the asynchronous system to receive the compressed packet forwarded by the data receiving server and returning corresponding feedback information to the client so as to complete data interaction.
In this embodiment, the data receiving server needs to forward the compressed packet after receiving the compressed packet, and at this time, the processing server can control the asynchronous system to receive the compressed packet forwarded by the data receiving server, and at the same time, the asynchronous system generates corresponding feedback information after receiving the compressed packet, and sends the feedback information to the client, so as to complete sequential data interaction, thereby effectively reducing the pressure of the whole processing server.
The asynchronous system can be a message middleware for storing the compressed package.
Step S104, all the compressed packets are fetched from the asynchronous system at preset time intervals to be decompressed to obtain decompressed DOM node information and click events, and the corresponding DOM node information and click events which are associated with the same user mark information are assembled according to the sequence of the time stamps to obtain intermediate video data which can be read back.
In this embodiment, the processing server may call out all the compressed packets from the asynchronous system for decompression every preset event, so as to obtain corresponding DOM node information and click events. The processing server can assemble corresponding DOM node information and click events which are associated with the same user mark information according to the sequence of the time stamps, so that intermediate video data is obtained. In general, the data receiving server and the asynchronous system can receive compressed packets from different clients, so that DOM node information and click events associated with the same user identification information are assembled to obtain a video operated by the same user on the client. The data is assembled according to the sequence of the time stamps, i.e. according to the time axis.
Further, the method in this embodiment may further include the steps of:
step S105, uploading the intermediate video data to a blockchain for reading and viewing by a user.
In this embodiment, based on the corresponding intermediate video data obtained after the data processing, the intermediate video data is uploaded to the blockchain to ensure the security and the fair transparency to the user. The user device may download the intermediate video data from the blockchain to verify that the relevant information has been tampered with. The blockchain referred to in this embodiment is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. The Blockchain (Blockchain), which is essentially a decentralised database, is a string of data blocks that are generated by cryptographic means in association, each data block containing a batch of information of network transactions for verifying the validity of the information (anti-counterfeiting) and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, an application services layer, and the like.
Further, after the step S102 of the method in this embodiment, the method further includes the following steps:
step S102', controlling the data receiving server to detect whether the received compressed packet is legal and safe according to a preset security check rule.
The processing server may control the data receiving server to detect whether the received compressed packet is legal or not according to a preset security check rule, specifically may detect whether the user flag information of the compressed packet is user flag information in a preset database, if so, it indicates that the received compressed packet is legal, and step S103 may be continued at this time. If not, the compressed packet is not legal, and the compressed packet can be deleted.
Further, the data receiving server includes a preset database, and the preset database includes a plurality of different preset user identification information, so step S102' of the present application may include the following steps:
controlling the data receiving server to acquire the user mark information of the compressed packet;
and controlling the data receiving server to judge whether the user mark information is preset user mark information in a preset database.
The processing server may control the data receiving server to obtain the user flag information of the compressed packet, if the user flag information is preset user flag information in a preset database, it indicates that the compressed packet is legal, step S103 may be continued, and if not, the compressed packet may be deleted.
In summary, the embodiment can comprehensively and rapidly restore the video recorded by the client through processing related video data, does not influence the operation of the user on the application program, and can be applied to scenes such as intelligent government affairs, thereby promoting the construction of intelligent cities and improving the use experience of the user.

Step S303, the control asynchronization system receives the compressed packet forwarded by the data receiving server and returns corresponding feedback information to the client to complete data interaction.
Step S304, all the compressed packets are fetched from the asynchronous system at preset time intervals to be decompressed to obtain decompressed DOM node information and clicking events, and the corresponding DOM node information and clicking events which are associated with the same user mark information are assembled according to the sequence of the time stamps to obtain intermediate video data which can be read back.
Step S305, retrieving a preset database and storing the intermediate video data in the preset database for the user to retrieve and view.
In this embodiment, the processing server is further capable of retrieving preset data, and storing the intermediate video data in a preset database, so that a user can retrieve and view the intermediate video data from the database.
In step S306, if the preset database access fails, the intermediate video data is stored in the local NAS volume.
In this embodiment, if the processing server fails to retrieve the preset database, the intermediate video data may be stored in the local NAS volume at this time, so that the user may retrieve the intermediate video data conveniently. The local NAS volume may refer to local storage.
Further, the method in this embodiment may further include the steps of:
step S307, if the screen recording completion request sent by the user is detected, the screen recording completion request is analyzed to obtain completion flag information, user flag information and a screen recording completion instruction.
Step S308, the client is controlled to stop screen recording according to the screen recording completion instruction, and the completion mark information associated with the user mark information is sequentially sent to a preset database through a data receiving server and an asynchronization system.
In this embodiment, if the processing server detects a screen recording completion request sent by the user, the processing server may analyze that the screen recording completion request has obtained completion flag information, user flag information, and a screen recording completion instruction. The completion flag information may flag that the user has completed the operation on the client, and the screen recording is completed. The processing server can control the blank guard short stop screen to record according to the screen recording completion instruction, and sends completion flag information associated with user flag information to the data receiving server, the data receiving server sends the completion flag information to the asynchronous system, and the asynchronous system can send the completion flag information associated with the user flag information to a preset database under the request of the processing server so as to be convenient for a user to read.
Further, the method in this embodiment may further include the steps of:
step S309, if a query request sent by a user is detected, the query request is parsed to obtain target user mark information.
In this embodiment, if the processing server detects a query request sent by a user, the processing server may continue to parse the query request to obtain target user flag information, where the target user flag information has certainty, and can satisfy the current requirement of the user, so as to facilitate viewing of corresponding intermediate video data.
Step S310, according to the target user mark information, all the intermediate video data including DOM node information associated with the target user mark information are called from a preset database to be checked.
In this embodiment, the processing server may retrieve all intermediate video data including DOM node information associated with the target user flag information from the preset database according to the target user flag information, and view the intermediate video data.
In addition, the processing server can also call all the intermediate video data of the click event including the relevant target user mark information from the preset database for viewing, so that the backtracking of the video is realized.
