DETAILED DESCRIPTION
Embodiments of the present invention are described in detail hereinafter, examples of the embodiments are shown in the drawings, and the same or similar reference numerals throughout the drawings denote the same or similar elements or elements having the same or similar functions. The embodiments described hereinafter with reference to the drawings are exemplary, are only intended to explain the present invention, and cannot be understood as limiting the present invention. The numbers of the steps in the following embodiments are only set for convenience of explanation, and the sequence of the steps is not restricted. The execution sequence of the steps in the embodiments may be adjusted adaptively according to the understanding of those of ordinary skills in the art.
In the description of the present invention, 'multiple" refers to being two or more, if there are descriptions of "first" and "second", it is only for the purpose of distinguishing technical features, and should not be understood as indicating or implying relative importance or implying the number of indicated technical features or implying the order of indicated technical features. In addition, unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those of ordinary skills in the art.
In current video stream sharing methods, after a user with whom a video stream is shared acquires a video stream playback address shared by others, the user may directly request the server to play back the video stream through this address by a general process as follows: (I) a user A requests the video stream playback address from the server by a terminal; (2) the server returns the video stream playing address to the terminal of the user A; (3) the user A shares the video stream playback address to a terminal of a user B by WeChat or Yixin; (4) the terminal of the user B requests to play back the video stream from the server through the address; and (5) the server acquires a real-time video stream from a camera and sends the real-time video stream to the terminal of the user B. It can be realized that, in the current video stream sharing methods, the video stream shared by others may be seen only by acquiring the video stream playback address, which has a risk of user privacy leakage caused by second sharing. For example, the user B may share the video stream playback address with a user C, and the user C may watch the surveillance video stream shared by the user A according to the video stream playback address. Thus, it can be seen that existing video stream sharing methods are insecure.
With reference to FIG. 1, an embodiment of the present invention provides a method for securely sharing a video stream, which comprises the following steps of: S101: acquiring a first playback address of a video stream to be shared from a server by a first terminal; S102. when the first terminal sends the first playback address to a terminal to be shared with, generating a first check code by the first terminal, and sending the first check code to the terminal to be shared with and the server respectively; S103: when a second terminal sends a video stream playback request to the server according to the first playback address, sending a second check code to the server by the second terminal, wherein the second check code is a check code acquired when the second terminal receives the first playback address; and S104: verifying the second check code according to the first check code, and when the verification succeeds, sending the video stream to be shared to the second terminal by the sewer.
In the embodiment of the present invention, a verification mechanism is introduced into video stream sharing, a random check code is automatically generated and sent to the terminal to be shared with every time a video stream playback address is shared, and the check code of the terminal should be verified by the sewer every time the video stream is requested to be played back. Because only the initial first terminal can send the generated check code to the server, the video stream cannot be verified successfully after secondary sharing, so that the video stream is finally guaranteed to be securely shared and played back within a user-controllable range, and user privacy leakage is prevented, thus being very secure.
It can be understood that the second terminal may be a terminal with which the first terminal directly shares the first playback address (which is namely the terminal to be shared with), or a terminal which acquires the first playback address through other terminals (excluding the first terminal). When each terminal shares the video stream playback address, the random check code needs to be generated and sent to the next terminal. However, only the initial first terminal which directly acquires the video stream playback address from the server can send the generated check code to the server. Therefore, only the terminal which directly acquires the first playback address from the first terminal may be verified successfully in the sewer, and the terminal of secondary or more sharing cannot be verified successfully.
FIG. 2 is a flow chart showing failed verification of secondary sharing of the video stream provided by an embodiment of the present invention. An embodiment of the present invention is described hereinafter with reference to FIG. 2: (I) the user A requests a first playback address of a target video stream from the server by a terminal a; (2) the server returns the first playback address to the terminal a; (3) the user A shares the first playback address with a terminal b of the user B through the terminal a, the first check code is randomly generated, and the first check code is sent to the terminal b and the server at the same time (4) the terminal b requests the server to play back the target video stream through the first playback address, and sends the first check code to the server; (5) the sewer verifies the first check code, the verification succeeds, and a real-time video stream is acquired from a target camera, (6) the sewer sends the real-time video stream to the terminal b, and the terminal b plays back the real-time video stream, so that the video stream subjected to initial sharing can be successfully played back, (7) the user B shares the first playback address with a terminal c of the user C through the terminal b, the second check code is randomly generated at the same time and the second check code is sent to the terminal c (but is not sent to the server); (8) the terminal c requests the server to play back the target video stream through the first playback address, and sends the second check code to the sewer; and (9) the server verifies the second check code, because the second check code is different from the check code sent by the terminal a to the server, the verification fails, and the terminal c cannot play back the target video stream, so that the video stream subjected to secondary sharing cannot be successfully played back.
Further, as an optional embodiment, the method for securely sharing a video stream further comprises the step of establishing a check code library, which specifically comprises: when the first terminal sends the first playback address to a plurality of terminals to be shared with, generating a plurality of first check codes by the first terminal, and sending the first check codes to the server, and establishing the check code library according to the first check codes.
Specifically, when the first terminal shares the video playback address with the plurality of terminals to be shared with, one random check code may be generated in each sharing and sent to the server, so that the check code library may be established in the server, thus being convenient for subsequent verification and management of the check codes.
Further, as an optional embodiment, the step SI04 of verifying the second check code according to the first check code, and when the verification succeeds, sending the video stream to be shared to the second terminal by the server, specifically comprises: S1041: carrying out traversal query in the check code library, wherein when the first check code identical to the second check code exists in the check code library, it is indicated that the verification succeeds, and when the first check code identical to the second check code does not exist in the check code library, it is indicated that the verification fails; and S1042: when the verification succeeds, acquiring the video stream to be shared according to the first playback address, and then sending the video stream to be shared to the second terminal by the server.
Further, as an optional embodiment, the method for securely sharing a video stream further comprises the following step of: when the first terminal sends a share canceling instruction to the server, deleting the corresponding first check code in the check code library according to the share canceling instruction.
Specifically, it is equivalent to acquiring authorization that the terminal to be shared with acquires the video stream playback address through the first terminal. When video sharing with a certain user or terminal needs to be canceled, which means to cancel authorization, the share canceling instruction may be sent to the server by the first terminal, and the server deletes a corresponding check code in the check code library, so that the user or terminal cannot watch the target video stream next time. In the embodiment of the present invention, the check code in the check code library may be added or deleted at any time by the first terminal, thus realizing the maintenance of the check code library and the authorization management of different terminals.
Further, as an optional embodiment, the video stream to be shared is a video stream shot by a target camera in real time.
Specifically, the video stream to be shared in the embodiment of the present invention may be the video stream shot by the target camera in real time or the video stream stored in the server, and may have different definitions in combination with different application scenarios. In the technical field of video surveillance, the real-time video stream acquired by the camera mostly contains personal privacy of the user, and user privacy leakage may be caused by secondary sharing. By using the method in the embodiment of the present invention, not only the video stream can be shared with others, but also security of video sharing can be ensured, and the secondary sharing is prevented.
With reference to FIG. 3, an embodiment of the present invention provides a system for securely sharing a video stream, which comprises: an address acquisition module configured for acquiring a first playback address of a video stream to be shared from a server by a first terminal; a check code generation module configured for, when the first terminal sends the first playback address to a terminal to be shared with, generating a first check code by the first terminal, and sending the first check code to the terminal to be shared with and the server respectively; a request module configured for, when a second terminal sends a video stream playback request to the sewer according to the first playback address, sending a second check code to the server by the second terminal, wherein the second check code is a check code acquired when the second terminal receives the first playback address; and a verification module configured for verifying the second check code according to the first check code, and when the verification succeeds, sending the video stream to be shared to the second terminal by the server.
Further, as an optional embodiment, the system for securely sharing a video stream further comprises a check code library establishment module, and the check code library establishment module comprises: a sending unit configured for, when the first terminal sends the first playback address to a plurality of terminals to be shared with, generating a plurality of first check codes by the first terminal, and sending the first check codes to the server; and an establishment unit configured for establishing the check code library according to the first check codes.
