In the description of the present application, the plurality means two or more, and if the description is made to the first and second for the purpose of distinguishing technical features, it should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the precedence of the indicated technical features. Furthermore, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.
In the current video stream sharing method, after a shared user obtains a video stream playing address shared by others, the shared user can directly request to play the video stream to a server through the address, and the general flow is as follows:
(1) The user A requests a video stream playing address from a server through a terminal of the user A;
(2) The server returns a video stream playing address to the terminal of the user A;
(3) The user A shares the video stream playing address to the terminal of the user B through WeChat or WeChat;
(4) The terminal of the user B requests the server to play the video stream through the address;
(5) The server obtains the real-time video stream from the camera and sends it to the user B's terminal.
It can be appreciated that in the current video stream sharing method, only the video stream playing address needs to be acquired to see the video stream shared by others, so that there is a risk of disclosure of privacy of the user caused by secondary sharing, for example, the user B may share the video stream playing address to the user C, and the user C may see the monitoring video stream shared by the user a according to the video stream playing address. It can be seen that the existing video stream sharing method is not secure.
Referring to fig. 1, an embodiment of the present application provides a video stream secure sharing method, which specifically includes the following steps:
s101, acquiring a first play address of a video stream to be shared from a server through a first terminal;
s102, when a first terminal sends a first play address to a terminal to be shared, generating a first check code through the first terminal, and respectively sending the first check code to the terminal to be shared and a server;
s103, when the second terminal sends a video stream playing request to the server according to the first playing address, a second check code is sent to the server through the second terminal, and the second check code is acquired when the second terminal receives the first playing address;
and S104, verifying the second check code according to the first check code, and if verification is successful, sending the video stream to be shared to the second terminal through the server.
According to the embodiment of the application, a verification mechanism is introduced in video stream sharing, random verification codes are automatically generated and sent to the terminal to be shared when video stream playing addresses are shared each time, verification codes of the terminal are verified through the server each time video stream playing is requested, and because only the initial first terminal can send the generated verification codes to the server, verification of the video stream after secondary sharing cannot be successful, safe sharing and playing of the video stream in a controllable range of a user are finally ensured, privacy leakage of the user is prevented, and the video stream sharing method is quite safe.
It can be understood that the second terminal may be a terminal (i.e. a terminal to be shared) where the first terminal directly shares the first play address, or may be a terminal where the first play address is obtained through another terminal (not the first terminal); when each terminal shares the video stream playing address, a random check code needs to be generated and sent to the next terminal, however, only the first terminal which directly obtains the video stream playing address from the server initially can send the generated check code to the server, so that only the terminal which directly obtains the first playing address from the first terminal can be successfully verified at the server, and the terminal which is shared by two or more times can not be successfully verified.
Fig. 2 is a schematic flow chart of a video stream two-time sharing method according to an embodiment of the application. One embodiment of the application is described below in connection with fig. 2:
(1) A user A requests a first playing address of a target video stream from a server through a terminal a;
(2) The server returns a first play address to the terminal a;
(3) The user A shares a first playing address with the terminal B of the user B through the terminal a, randomly generates a first check code and simultaneously sends the first check code to the terminal B and the server;
(4) The terminal b requests the server to play the target video stream through the first play address and sends the first check code to the server;
(5) The server verifies the first check code, the verification is successful, and a real-time video stream is obtained from the target camera;
(6) The server sends the real-time video stream to a terminal b, and the terminal b plays the real-time video stream, so that the video stream can be successfully played through primary sharing;
(7) The user B shares the first playing address with the terminal C of the user C through the terminal B, randomly generates a second check code at the same time, and sends the second check code to the terminal C (not to the server);
(8) The terminal c requests the server to play the target video stream through the first play address and sends the second check code to the server;
(9) The server verifies the second check code, and as the second check code is different from the check code sent to the server by the terminal a, the verification fails, and the terminal c cannot play the target video stream, so that the video stream cannot be successfully played through secondary sharing.
Further, as an optional implementation manner, the video stream secure sharing method further includes a step of constructing a check code library, which specifically includes:
when a first terminal sends a first playing address to a plurality of terminals to be shared, generating a plurality of first check codes through the first terminal, and sending the first check codes to a server;
and constructing a check code library according to the first check code.
Specifically, when the first terminal shares the video playing address with the plurality of terminals to be shared, a random check code is generated for each sharing and sent to the server, so that a check code library can be built in the server, and the follow-up verification and management of the check codes are facilitated.
Further, as an optional implementation manner, the second check code is verified according to the first check code, and if verification is successful, the step S104 of sending, by the server, the video stream to be shared to the second terminal specifically includes:
s1041, performing traversal inquiry in a check code library, and if a first check code which is the same as a second check code exists in the check code library, verifying successfully, otherwise, failing to verify;
and S1042, when verification is successful, acquiring a video stream to be shared according to the first play address, and further sending the video stream to be shared to the second terminal through the server.
Further as an optional implementation manner, the video stream secure sharing method further includes the following steps:
and when the first terminal sends a sharing canceling instruction to the server, deleting the corresponding first check code in the check code library according to the sharing canceling instruction.
Specifically, the terminal to be shared that obtains the video stream playing address through the first terminal is equivalent to obtaining the authorization, when the video sharing, that is, the authorization, needs to be cancelled for a certain user or terminal, the first terminal can send a command for cancelling the sharing to the server, and the server deletes the corresponding check code in the check code library, so that the user or terminal cannot watch the target video stream next time. The embodiment of the application can add or delete the check codes in the check code library through the first terminal at any time, thereby realizing the maintenance of the check code library and the authorization management of different terminals.
Further as an optional implementation manner, the video stream to be shared is a video stream photographed by the target camera in real time.
Specifically, the video stream to be shared in the embodiment of the application can be a video stream shot by the target camera in real time, or can be a video stream stored in a server, and can be defined differently in combination with different application scenes. In the technical field of video monitoring, a real-time video stream acquired by a camera mostly contains personal privacy of a user, and secondary sharing can cause privacy leakage of the user.

the address acquisition module is used for acquiring a first play address of the video stream to be shared from the server through the first terminal;
the verification code generation module is used for generating a first verification code through the first terminal when the first terminal sends a first play address to the terminal to be shared, and respectively sending the first verification code to the terminal to be shared and the server;

and the verification module is used for verifying the second verification code according to the first verification code, and if the verification is successful, the video stream to be shared is sent to the second terminal through the server.
Further as an optional implementation manner, the video stream security sharing system further includes a check code library construction module, where the check code library construction module includes:
the sending unit is used for generating a plurality of first check codes through the first terminal when the first terminal sends the first play address to the plurality of terminals to be shared, and sending the first check codes to the server;
and the construction unit is used for constructing a check code library according to the first check code.
