Referring to fig. 1, a video playing method of an example embodiment provided by the present disclosure may include the following steps S110 to S140.
Step S110, in response to receiving a first video playing request sent by the client, inquiring target service authority of the client host corresponding to the SIM card user, so as to establish an IP pipeline between the client host and the video platform under the condition that the SIM card user has the target service authority.
In the present exemplary embodiment, the first video play request may be generated by an operation of the user on the front page, for example, an operation of clicking a play video by the user, or the like. The first video playing request may include identification information of a video to be played, service type information (such as video service, voice service, color ring service, etc.), service number information, etc., and may further include request time, request user information (such as user identification information, user account information, user name information, etc.), which is not limited in this example.
In this example embodiment, the information base may be used to query the information base of the user information corresponding to the SIM card user information of the client host through the request user information carried in the first video playing request, where the SIM card user information may include information such as a user type of the SIM card, a user identifier, a service opened by the user, and the like, to determine whether the video service (target service) is opened by the SIM card user, and in the case where the video service (target service) is opened by the SIM card user, an IP pipe is established between the client host and the video platform.
In the present exemplary embodiment, an IP (Internet Protocol ) pipe refers to a communication channel established in an IP network. Illustratively, the IP tunnel can be formed by establishing a VXLAN (Virtual eXtensible Local Area Network, virtual extended 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 adopts a message encapsulation mode of L2 over L4 (MAC-in-UDP), so that two-layer messages are encapsulated by using a three-layer protocol, so that the two-layer network can be expanded within a three-layer range, and meanwhile, the requirements of large two-layer virtual migration and multi-tenant of a data center are met.
The VXLAN tunnel is used to transmit packets encapsulated by VXLAN, and is a virtual channel established between two VTEPs (VXLAN Tunnel Endpoints ), which are edge devices of the VXLAN network, and are the start point and the end point of the VXLAN tunnel. The start point and the end point of the VXLAN tunnel in this example are the client host, the video platform. Other ways of establishing the IP pipe may be used in this example, which is not limited in this example.
Step S120, in response to a second video playing request sent to the video platform by the client through the IP pipeline, determining the target video playing authority 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 tunnel is established, the broadband access management system will assign the client an IP address to access the video platform. And triggering the client to send a second video playing request to the video platform when the IP address is received. The second video playing request is a video playing request initiated after the IP pipe is established, which 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, for example, video identification information to be played, request user information, and the like, which is not limited in this example.
In this example 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 playing authority of the requested target video is queried in the information base. In this example, the target video playing authority of the user is determined by establishing an IP pipe, and by a one-to-one correspondence between pipe information of the IP pipe and the SIM card user.
Step S130, when the SIM card user has the target video playing authority, digital watermark information is generated 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, IP pipe number, two end point information of the IP pipe, IP pipe setup time, end time, and other information related to the IP pipe, which is not limited in this example.
In this example embodiment, when the SIM card user has the target video playing authority, digital watermark information may be generated for the current video playing request of the SIM card user. The digital watermark information may be a series of numbers or serial numbers generated according to the pipeline information of the IP pipeline, for example, a random number or a random serial number may be generated according to the IP pipeline ID, or digital watermark information may be generated by using a certain rule, for example, the IP pipeline ID may be generated by using hash transformation, or other custom or existing mapping rules, which is not limited in this example.
And step S140, the digital watermark information is sent to the video platform, so that the video platform adds the digital watermark information to the target video, codes and encrypts the target video, and decrypts and plays the coded 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 the digital watermark, for example, may be added to the target video in a layer manner. After the digital watermark information is added, video data is encoded and encrypted, and then decrypted and played through a client, wherein the played video has the digital watermark information, so that the copying behavior of the video is tracked conveniently.
In the communication network video playing method provided by the embodiment of the disclosure, under the condition that a subscriber of an SIM card has target service authority, an IP pipeline is established between a client host and a video platform, and the target video playing authority of the subscriber of the SIM card corresponding to pipeline information of the IP pipeline is determined in response to a second video playing request sent to the video platform by the client 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 one hand, pipeline information of an IP pipeline is added into a target video through digital watermarking, so that the video subjected to the copying has the digital watermarking, video tracking can be realized according to the digital watermarking information, and the user information of the copying is determined, so that the problem of monitoring video leakage caused by the event 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 pipeline information of the IP pipeline is IP pipeline identification information, and generating the digital watermark information according to the pipeline information of the IP pipeline includes:
and generating a corresponding random number according to the IP pipeline identification information.
In this example embodiment, a fixed number of bits (e.g., 16 or 32) of random numbers may be correspondingly generated based on the IP pipe ID. The correspondence between the IP pipeline ID and the random number may be recorded to locate the video clip player during subsequent video tracking.
The random number is used as digital watermark information.
In this example embodiment, the random number may be transmitted to the video platform as digital watermark information, and the video platform may superimpose the random number as a layer in the decoded video to be played (target video). Such that the digital watermark information is presented as part of the target video during playback.
In some embodiments, after IP pipe establishment, the method further comprises:
and receiving an IP pipeline establishment notification message sent by the broadband access management system, wherein the IP pipeline establishment notification message is used for indicating that the establishment of the IP pipeline is completed, and the IP pipeline establishment notification message comprises pipeline information of the IP pipeline.

The IP pipe related information may be stored in the form of a video CDR (Call Detail Record ).
In some embodiments, referring to fig. 2, the client host has a SIMKey; the method further comprises the following steps S210-S250.
Step S210 determines SIMKey card user information and digital certificate information.
In this example embodiment, the user may be a SIMKey user, and the video security platform may determine the SIMKey card user information and the digital certificate information by querying the SIMKey.
Step S220, binding the association relationship between the SIMKey card user information and the digital certificate information.
In this example embodiment, the user information associated with the SIMKey and the digital certificate information may be bound in advance on the video security platform, so that the SIMKey card user information determines the corresponding digital certificate information.
Step S230, determining corresponding SIMKey card user information according to the pipe information of the IP pipe.
In the present exemplary embodiment, the IP pipe is established based on the first video play request of the SIMKey card user, both of which are in one-to-one correspondence, so the SIMKey card user information can be determined by the pipe information of the IP pipe.
Step S240, determining the digital certificate information corresponding to the SIMKey card user information according to the association relation.
In this example embodiment, digital certificate information corresponding to the SIMKey card user information may be determined according to the binding association relationship.
Step S250, the digital certificate information is sent 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 example 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, where the client decrypts and plays the video by using the digital certificate in the SIMKey as the user private key, so that the video is prevented from being attacked or intercepted maliciously, and the security of the network video playing process is ensured.
In some embodiments, after the client decrypts and plays the encoded encrypted video, the method further comprises:
and receiving an IP pipeline dismantling notification message sent by the broadband access management system, wherein the IP pipeline dismantling notification message is used for indicating that the IP pipeline is dismantled, and the IP pipeline dismantling notification message comprises the pipeline information of the IP pipeline.
In this example embodiment, after the target video requested by the client is played, the broadband access management system tears down the IP pipe established for the target video and notifies the video security platform. The IP pipe removal notification message may include IP pipe identification information, and may also include other IP pipe related information, such as removal time, etc., which is not limited in this example. The video security platform may update information in the video CDR, for example, update the state of the IP pipe from the existing state to the torn down state, upon receiving the IP pipe tear down notification message.
According to the method and the device, the IP pipeline is built according to the first video playing request, after video playing is finished, the IP pipeline is dismounted by the vertical horse, so that the IP pipeline is built and dismounted at any time, a pipeline is newly built every time a user accesses video content, and when the video is played, the IP pipeline is dismounted without affecting an IP network.
In some embodiments, referring to fig. 3, the video playing specific process of the present disclosure may include the following steps S301-S318.
In step S301, the client triggers a video playing operation, and the client sends a first video playing request to the broadband access management system.
In step S302, the broadband access management system forwards the first video playing request to the video security platform.
In step S303, the video security platform performs an authentication for the first video playing request.
In this example, one authentication may be to query the video service authority of the SIMKey card user, determine whether the SIM card user has the video service authority, if so, go to step S303, otherwise, return the no-authority reminder.
Step S304, the video security platform returns an authentication result to the broadband access management system.
In step S305, when one authentication passes, the broadband access management system establishes an IP pipe based on the first video play request.
In step S306, the broadband access management system notifies the video security platform of the IP pipeline related information, so that the video security platform stores the IP pipeline related information, thereby facilitating tracking of subsequent video playback.
In step S307, the broadband access management system allocates an IP address to the client according to the IP pipe, and transmits pipe information of the IP pipe.
In step S308, the client sends a second video playing request to the video platform through the IP pipeline.
Step S309, the video platform forwards the second video playing request to the video security platform for secondary authentication.
In this example, the secondary authentication refers to determining whether the SIMKey card user corresponding to the pipe information of the IP pipe has the target video play right. Corresponding SIMKey card user information can be determined according to the pipeline information of the IP pipeline, and then the target video playing authority of the user information can be determined according to the SIMKey card user information.
Step S310, the video security platform generates digital watermark information according to the pipeline information of the IP pipeline for the request of the secondary authentication passing.
Step S311, the video security platform returns the digital watermark information and the secondary authentication result to the video platform.
Step S312, the video security platform determines digital certificate information corresponding to the current second video playing request according to the association relation between the bound SIMKey card user information and the digital certificate information, and returns the digital certificate information to the video platform. The association in this example is bound in advance at the video security platform.
In step S313, the video platform adds digital watermark information to the target video and encodes the digital watermark information.
In step S314, the video platform encrypts the encoded video using the digital certificate information and the symmetric key.
