Referring to fig. 1, a video playing method according to an example embodiment of the present disclosure may include the following steps S110 to S140.
Step S110, in response to receiving the first video playing request sent by the client, querying a target service permission of the client host corresponding to the SIM card user, so as to establish an IP pipe between the client host and the video platform when the SIM card user has the target service permission.
In the present exemplary embodiment, the first video playing request may be generated by a user operation on the front end page, for example, the user clicks an operation of playing a video, and the like. The first video playing request may include identification information of a video to be played, service type information (e.g., video service, voice service, color ring service, etc.), service number information, and the like, and may also include request time and request user information (e.g., user identification information, user account information, user name information, etc.), which is not limited in this example.
In this exemplary embodiment, the information of the SIM card corresponding to the client host may be queried in the information base through the requesting user information carried in the first video playing request, where the SIM card user information may include information of a user type, a user identifier, a service that the user has opened, and the like of the SIM card, and determine whether the SIM card user has opened a video service (target service), and an IP pipe is established between the client host and the video platform when the SIM card user has opened the video service (target service).
In the present exemplary embodiment, an IP (Internet Protocol) pipe refers to a communication channel established in an IP network. Illustratively, the IP pipe may be formed by establishing a VXLAN (Virtual eXtensible Local Area Network) tunnel in the IP Network. VXLAN is one of NVO3 (Network Virtualization over Layer 3) standard technologies defined by IETF (The Internet Engineering Task Force), and a two-Layer message is encapsulated by a three-Layer protocol by adopting a message encapsulation mode of L2 over L4 (MAC-in-UDP), so that The two-Layer Network can be expanded in a three-Layer range, and The requirements of large two-Layer virtual migration and multiple tenants of a data center are met.
The VXLAN Tunnel is used to transmit messages encapsulated by VXLAN and is a virtual channel established between two VTEPs (VXLAN Tunnel Endpoints), where a VTEP is an edge device of a VXLAN network and is a start point and an end point of a VXLAN Tunnel. The start and end points of the VXLAN tunnel in this example are the client host, the video platform. The IP pipe may also be established in other manners in this example, which is not limited in this example.
And step S120, responding to a second video playing request sent to the video platform by the client through the IP pipeline, and determining the target video playing permission of the SIM card user corresponding to the pipeline information of the IP pipeline according to the pipeline information of the IP pipeline.
In this example embodiment, after the IP pipe is established, the broadband access management system will assign the client an IP address to access the video platform. And when the IP address is received, the client is triggered to send a second video playing request to the video platform. The second video playing request is a video playing request initiated after the IP pipe is established, and may include, in addition to the allocated access IP address, pipe information of the IP pipe (such as an IP pipe ID), and may further include all or part of information included in the first video request, such as identification information of a video to be played, information of a requesting user, and the like, which is not limited in this example.
In this exemplary embodiment, the SIM card user information may be determined according to the pipe information of the IP pipe, and then, whether the SIM card user has the requested playback right of the target video is queried in the information base. In this example, by establishing an IP pipe, the target video playing authority of the user is determined through the one-to-one correspondence between the pipe information of the IP pipe and the SIM card user.
And step S130, when the SIM card user has the target video playing authority, generating digital watermark information according to the pipeline information of the IP pipeline.
In this example embodiment, the pipe information of the IP pipe may include information such as IP pipe identification information, an IP pipe number, two end point information of the IP pipe, IP pipe setup time, and end time, and may further include other information related to the IP pipe, which is not limited in this example.
In this exemplary embodiment, when the SIM card user has the target video playing authority, the digital watermark information may be generated for the current video playing request of the SIM card user. The digital watermark information may be a string of numbers or serial numbers generated according to the pipe information of the IP pipe, for example, a random number or a random serial number may be generated according to the IP pipe ID, or the digital watermark information may be generated by using a certain rule, for example, the IP pipe ID is used for generating the digital watermark information by using hash transform, or may be other self-defined or existing mapping rules, which is not limited in this example.
Step S140, sending the digital watermark information to the video platform, so that the video platform adds the digital watermark information to the target video, encodes and encrypts the target video, and decrypts and plays the encoded and encrypted video through the client.
In this exemplary embodiment, the digital watermark information may be added to the target video in a custom manner or in an existing manner of adding a digital watermark, for example, may be added to the target video in an image layer manner. And after the digital watermark information is added, the video data is encoded and encrypted, and then is decrypted and played by the client, wherein the played video is provided with the digital watermark information so as to track the copying behavior of the video.
In the communication network video playing method provided by the embodiment of the disclosure, under the condition that an SIM card user has a target service authority, an IP pipeline is established between a client host and a video platform, and the target video playing authority of the SIM card user corresponding to the pipeline information of the IP pipeline is determined in response to a second video playing request sent by a client to the video platform through the IP pipeline; when the SIM card user has the target video playing authority, generating digital watermark information according to the pipeline information of the IP pipeline; and adding digital watermark information to the target video. On the one hand, the pipeline information of the IP pipeline is added into the target video through the digital watermark, so that the copied video has the digital watermark, video tracking can be achieved according to the digital watermark information, the copied user information is determined, the problem of leakage of the monitoring video caused by the events is reduced to a certain extent, and the safety of the network monitoring video is improved. On the other hand, the video acquisition process in the IP network is realized by establishing the IP pipeline, so that a network operator can track the actual geographic position of the target video player through the access gateway, and the accurate positioning of the target video player is realized.
In some embodiments, the pipe information of the IP pipe is IP pipe identification information, and the generating of the digital watermark information according to the pipe information of the IP pipe includes:

And step S230, determining corresponding SIMKey card user information according to the pipeline information of the IP pipeline.
In this exemplary embodiment, the IP pipe is established based on the first video playback request of the SIMKey card user, and the two requests correspond to each other one by one, so that the SIMKey card user information can be determined by the pipe information of the IP pipe.
Step S240, determining digital certificate information corresponding to the SIMKey card user information according to the association relationship.
In this example embodiment, the digital certificate information corresponding to the SIMKey card user information may be determined according to the association relationship of the binding.
And step S250, sending the digital certificate information to the video platform so that the video platform generates a symmetric key according to the digital certificate information to encrypt the encoded video.
In this exemplary embodiment, the digital certificate information may be used as a video key to encrypt the encoded video, and then the encrypted video stream is returned to the client through the IP pipeline, and the client decrypts and plays the video by using the digital certificate in the SIMKey as a user private key, so that the video is prevented from being maliciously attacked or intercepted, and the security of the network video playing process is ensured.
