Description
Technical Field
The invention relates to the technical field of internet video live broadcast, in particular to the technical field of HLS video live broadcast anti-theft chains.
Background
The stealing link means that the service provider does not provide the service content by itself, and bypasses other beneficial end user interfaces (such as advertisements) through technical means, and the service content of other service providers is directly provided for the end user on the website of the service provider, so as to cheat the browsing and click rate of the end user. The beneficiary does not provide the resource or provides little resource, and the true service provider does not receive any benefit. Since the Http technology is adopted for audio and video transmission in ordinary Http Live Streaming (Http Live Streaming is a protocol defined by Apple inc.) video Live broadcasting, an M3U8 file address for acquiring an audio and video address is easily intercepted, so that a video link is easily stolen.
At present, the mainstream social frequency live broadcast platform is limited in terms of anti-theft links by adopting modes such as link encryption, random names and time limitation, but since the finally adopted player is public third-party software, experienced software personnel can easily obtain actual video source links. The video can be browsed within the time limit range after the link is acquired, and the video is automatically acquired after the time is out, so that the difficulty of the anti-theft chain is increased, and the anti-theft chain cannot be completely eradicated.
Another video anti-theft method is video stream encryption, but because the encryption and decryption process occupies a large amount of system resources, especially in the aspect of mobile video live broadcast, video stream encryption is rarely applied in the aspect of video live broadcast.

In view of the above drawbacks of the prior art, an object of the present invention is to provide a method and a system for live HLS video anti-theft chain, which are used to solve the problems in the prior art that the anti-theft chain is not high in security and is easy to be stolen.
In order to solve the technical problems, the invention adopts the technical scheme that: the method for the HLS video live broadcast anti-theft chain comprises the following steps:
s10, when a live broadcast service request is received, generating a verification value and an associated value uniquely associated with the verification value according to the URL, the timestamp and the user identification of the live broadcast service;
s20, assembling a live broadcast service request according to the URL, the timestamp and the verification value of the live broadcast service, and assembling a heartbeat keeping request according to the URL, the timestamp, the verification value and the correlation value of the live broadcast service;
s30, when receiving the re-assembled live broadcast request sent by the user client, starting to send a video live broadcast stream according to the URL of the live broadcast service and the format of the request;
and S40, when the heartbeat maintaining request sent by the service platform is received, judging whether to continuously send the video live stream according to the maintaining identifier in the heartbeat maintaining request.
In order to solve the technical problem, the invention adopts another technical scheme as follows: a system of an HLS video live broadcast anti-theft chain is provided, and comprises:
the verification value correlation value generation module is used for generating a verification value and a correlation value uniquely correlated with the verification value according to the URL, the timestamp and the user identification of the live broadcast service when a live broadcast service request is received;
the request assembling module is used for assembling a heartbeat keeping request according to the URL, the timestamp, the verification value and the correlation value of the live broadcast service;
the video issuing module is used for issuing a video live stream according to the URL of the live broadcast service and the format of the request when receiving the re-assembled live broadcast request sent by the user client;
and the heartbeat maintaining module is used for judging whether to continuously send the live video stream according to a maintaining identifier in the heartbeat maintaining request when receiving the heartbeat maintaining request sent by the service platform.
The invention has the beneficial effects that: even if a link thief intercepts a live video address, the link address is random and can only be linked once, so that the video cannot be browsed even if third-party software acquires the live video address, the link stealing behavior of illegal users can be effectively prevented, and the processing capacity of live broadcast service is guaranteed.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 3, the idea of the present invention is to implement a hotlink using a method of authentication associated with a service platform. Firstly, a business service platform and an HLS video stream service platform complete login verification and establish a communication channel; then, the user side needs to apply for the video streaming service through a service platform, and the service platform acquires a corresponding video streaming address from the HLS video streaming service platform; and finally, the user side acquires the video stream by using the video stream address provided by the service platform.
During video browsing, the user side has a state maintaining relationship with the service platform, the service platform and the HLS video streaming service platform. And when the video stream browsing stops or fails, informing the HLS video stream service platform to stop the pushing of the video stream. And generating a random video stream ID every time a video stream is applied, wherein the video stream can only generate video connection once so as to ensure that the HLS video stream service platform can confirm whether a hotlink is generated. The following description will be given with reference to specific examples.
Method embodiment
Referring to fig. 1, the technical solution adopted in this embodiment is as follows: the method for the HLS video live broadcast anti-theft chain comprises the following steps:
s10, when a live broadcast service request is received, generating a verification value and an associated value uniquely associated with the verification value according to the URL, the timestamp and the user identification of the live broadcast service;
s20, assembling a live broadcast service request according to the URL, the timestamp and the verification value of the live broadcast service, and assembling a heartbeat keeping request according to the URL, the timestamp, the verification value and the correlation value of the live broadcast service;
s30, when receiving the re-assembled live broadcast request sent by the user client, starting to send a video live broadcast stream according to the URL of the live broadcast service and the format of the request;
and S40, when the heartbeat maintaining request sent by the service platform is received, judging whether to continuously send the video live stream according to the maintaining identifier in the heartbeat maintaining request.
Firstly, a business service platform and an HLS video stream service platform complete login verification and establish a communication channel; specifically, the application client submits a user identifier, such as a CameraID, to the service platform to obtain a corresponding M3U8 URL; the service platform initiates an HTTP GET request to the video service platform, and acquires a user identifier with a file name submitted by the application client, wherein the user identifier is a CameraID added with yum suffixes. The method comprises the following specific steps:
GET/CameraID.yum HTTP/1.1
