Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
FIG. 1 illustrates an exemplary operating environment in which embodiments of the present application can be implemented. Referring to fig. 1, the operation environment includes a video terminal 100, a server 200, and a display 300. The video terminal 100, the server 200 and the display 300 are all provided with a wireless communication module, and the video terminal 100 and the server 200 are connected through the wireless communication module. The wireless communication module can be a WIFI module, a Bluetooth module or a mobile communication module. The server 200 and the display 300 may be connected by a wireless communication module or may be connected by a cable.
The video terminal 100 includes a camera, an environment data collector 120, a character superimposer 130, and a controller 140. The character superimposer 130 is connected to the camera, the environmental data collector 120, and the controller 140, respectively.
The camera is used for collecting environmental pictures and outputting video data, namely the video data are video pictures of a monitored environment.
The environment data collector 120 includes various types of environment detection sensors. The environmental data collector 120 includes an environmental detection sensor capable of monitoring and controlling the environment, such as a soil temperature sensor, an air temperature and humidity sensor, an evaporation sensor, a rainfall sensor, an illumination sensor, a wind speed and direction sensor, and the like. The environment acquisition sensor is used for outputting environment data according to a monitored environment, and the environment data comprises environment soil temperature, environment air temperature and humidity, environment evaporation degree, environment rainfall, environment illumination intensity, environment wind power intensity, environment wind direction and other environment data.
The character superimposer 130 is configured to receive the video data and the environment data and superimpose the environment data onto the video data to obtain the actual acquisition information.
The controller 140 may be an FPGA chip or a DSP chip, the controller 140 is configured to control the camera 110 to output environment data, control the plurality of environment detection sensors to output environment data, and receive, store, and output actual acquisition information, and the controller 140 further stores an environment data transmission combination and a distribution rule. The controller 140 is connected to the server 200, and the server 200 may obtain the actual acquisition information through the controller 140.
It should be noted that the controller 140 has a control program for supporting the video terminal 100 to operate independently, so that the controller 140 can independently control the video terminal 100 to operate normally in a case of being detached from the server 200, the control command priority of the server 200 is higher than that of the control command of the controller 140, and the controller 140 preferentially executes the control command of the server 200 when the server 200 outputs the control command.
After receiving the actual acquisition information, the server 200 performs security check on the actual acquisition information to determine whether the actual acquisition information output by the video terminal 100 is trusted, and when the actual acquisition information is trusted, the server 200 transmits the actual acquisition information subjected to the security check to the display 300, so that a manager can visually see information of the monitoring environment. The display 300 may be a shadow map display 300 or a liquid crystal display 300, and the specific type is not limited herein.
Fig. 2 is a flowchart illustrating a video network transmission security verification method with environmental data according to an embodiment of the present application. Referring to fig. 2:
step S01: and generating a sending sequence number according to the sending time sequence of the broadcast.
Before operation, a communication link between the server 200 and the video terminal 100 needs to be established first. The establishment process of the communication link is as follows: the server 200 randomly transmits the time sequence to the video terminal 100 in a broadcast manner, and when the video terminal 100 receives the transmission sequence number, it indicates that the establishment of the communication link is completed. Since the broadcast format has a temporal characteristic, the time sequence sent by the server 200 has a temporal sequence, and the server 200 marks the temporal sequence to determine the sequence of receiving the actual acquisition information returned by the video terminal 100.
For example, if the server 200 sequentially transmits the sequence a, the sequence b, and the sequence c in the broadcast format, the sequence a, the sequence b, and the sequence c are the first transmission number, the second transmission number, and the third transmission number, respectively. Namely: the server 200 first receives and receives the actual acquisition information output by the video terminal 100 in the time sequence a, then receives and receives the actual acquisition information output by the video terminal 100 in the time sequence b, and finally receives and receives the actual acquisition information output by the video terminal 100 in the time sequence c. Note that the video terminal 100 that receives the a-sequence, the video terminal 100 that receives the b-sequence, and the video terminal 100 that receives the c-sequence are not the same video terminal 100, but three video terminals 100 that are independent of each other. Meanwhile, after the server 200 completes the security check of the actual acquisition information output by the video terminal 100 receiving the sequence a, the server 200 performs the security check of the actual acquisition information output by the video terminal 100 receiving the sequence b, thereby reducing the computational complexity of the server 200.
Step S02: the transmission sequence number output by the server 200 is acquired.
After the server 200 randomly outputs the transmission serial number, the plurality of video terminals 100 also randomly receive one transmission serial number output by the server 200, so that each data transmission between the server 200 and each video terminal 100 has randomness, thereby increasing the probability of exposing the video terminal 100 which is illegally invaded.
Since the number of video terminals 100 varies depending on the environment, the transmission number is determined according to the number of video terminals 100 in the actual environment. Meanwhile, the set sending sequence number should satisfy that one sending sequence number corresponds to one video terminal 100, so as to reduce the probability of calculation disorder of the server 200 caused by the video terminal 100 without the sending sequence number.
Step S03: and calling an environment data transmission combination according to the sending sequence number.
Before the environmental data transmission combination is called, the environmental data transmission combination needs to be established and pre-stored. The method for establishing the environment data transmission combination comprises the following steps: first, the controller 140 formulates a combination mode of each set of environmental data transmission combination according to the types of the camera 110 and the environmental detection sensor, and then outputs the combined environmental data transmission combination as a dispatch rule according to a preset sorting rule. The sorting rule may sort the sums of the video data and the environmental data included in the environmental data transmission combination, or may also serve as a sort according to the chronological order of the combination, and a specific sorting manner is not limited herein. Therefore, the dispatching rules are obtained by the multiple groups of environment data transmission combinations according to the preset sequencing, the first environment data transmission combination in the dispatching rules correspondingly sends the first number, the second environment data transmission combination in the sequencing correspondingly sends the second number, and so on, the Nth environment data transmission combination in the sequencing correspondingly sends the N number. N is any number other than the divisor value zero.
After determining the combination mode of each set of transmission combination of the environmental data and establishing the completed dispatch rule, the controller 140 stores the dispatch rule, and the controller 140 transmits the dispatch rule to the server 200. Thereby facilitating data transmission between the video terminal 100 and the server 200 according to the distribution rule.
Step S04: according to the transmission combination of the environment data, the corresponding environment data is superimposed to the video data acquired by the video terminal 100, and the actual acquisition information is generated.
After the environmental data transmission combination is called, the controller 140 obtains the combination mode of the video data and the environmental data in the environmental data transmission combination according to the environmental data transmission combination. Therefore, the controller 140 can control the camera to output the video data and control the corresponding environment detection sensor to output the environment data according to a combination manner of the video data and the environment data in the environment data transmission combination, and the character superimposer 130 receives the video data and the environment data output by the corresponding environment detection sensor and superimposes the received environment data onto the video data to generate the actual acquisition information.
And S05, receiving the actual acquisition information returned by the video terminal 100.
The controller 140 generates actual acquisition information according to a combination manner of the video data and the environmental data in the environmental data transmission combination, and outputs the actual acquisition information to the server 200. Since the actual acquisition information includes video data and environmental data, and the server 200 stores the same environmental data transmission combination, the server 200 can implement security check work after comparing the acquired actual acquisition information with the environmental data transmission combination.
Step S06: and judging whether the actual acquisition information is credible or not according to the actual acquisition information.
Judging whether the collected information is credible; and judging whether the actual collected information contains environmental data. The environmental data is obtained by the video terminal 100 according to the monitored environment, and if the actually acquired information does not contain the environmental data, it is indicated that the video terminal 100 outputting the actually acquired information has a security hole illegally replaced by a common camera, and the common camera does not have a superposition function.
When the first security check result of the server 200 on the actual acquisition information is not trusted, the server 200 sets the actual acquisition information as illegal acquisition information, and outputs prompt information according to the illegal acquisition information so as to prompt a manager that the video terminal 100 outputting the actual acquisition information has a security hole illegally replaced by a common camera. The prompt information is a signal for prompting the manager that the video terminal 100 is illegally intruded, so the prompt information may include a signal capable of prompting the manager in time, such as a special color flashing prompt, a voice prompt, a buzzer prompt, and the like. For example, when the server 200 outputs the prompt message, a red light on the server 200 blinks, and when the manager sees the red light blinking, it indicates that the video terminal 100 being verified at this time is hacked. The voice prompt and the buzzer prompt can be similar to the process of flashing prompt with special color, and are not described herein.
Step S07: and if the actual acquisition information is credible, determining target acquisition information according to the actual acquisition information.
Since the technology of the video network is rapidly developed, the actually collected information outputted from the video terminal 100, which is difficult to avoid being illegally intruded, also includes the environmental data. Therefore, in order to further improve the video network transmission security, it is necessary to perform security verification again on the actual capture information output by the video terminal 100. Specifically, the actual collected information that is trusted as a result of the first security verification is set as target collected information, and the server 200 inputs the target collected information into the process of the second security verification.
Step S08: and judging whether the target acquisition information is credible or not according to a preset distribution rule, the sending sequence number and the target acquisition information, wherein the preset distribution rule comprises environment data transmission combinations which are in one-to-one correspondence with the sending sequence number.
The method for judging whether the target acquisition information is credible by the server 200 comprises the following steps:
first, the server 200 determines an environment data transmission combination according to the transmission sequence number. Since each sending sequence number has a corresponding environment data transmission combination, the server 200 can determine the combination mode of the video data and the environment data in the actual acquisition information to be output by the video terminal 100 through the sending sequence number received by the video terminal 100. For example, a video network includes an X video terminal, a Y video terminal, a Z video terminal, and an H server, and the X video terminal, the Y video terminal, and the Z video terminal all include: the system comprises B0 video data, B1 environment data, B2 environment data, B3 environment data, B4 environment data and B5 environment data, wherein the B0 video data, the B1 environment data and the B2 environment data are combined into an X environment data transmission combination, the B0 video data, the B1 environment data, the B3 environment data and the B4 environment data are combined into a Y environment data transmission combination, the B0 video data, the B2 environment data, the B3 environment data and the B5 environment data are combined into a Z environment data transmission combination, if the dispatching rule is X-Y-Z, the sending sequence numbers respectively received by the X video terminal, the Y video terminal and the Z video terminal are a sending second number, a sending third number and a sending first number, and the sequence of security verification performed by the H server is the Z video terminal, the X video terminal and the Y video terminal.
Therefore, the server 200 can determine the combination of the video data and the environmental data in the actual capture information output by the video terminal 100 according to the transmission sequence number received by the video terminal 100.
And then, judging whether the environment data transmission combination corresponds to the target acquisition information. After determining the combination mode of the video data and the environmental data in the environmental data transmission combination according to the dispatch rule, the server 200 compares the combination mode of the video data and the environmental data contained in the target acquisition information. For example, the environment data transmission combination includes an environment picture, an environment temperature, an environment rainfall and an environment wind direction, and the target collection information includes an environment picture, an environment temperature and an environment wind direction, and the target collection information is considered not to correspond to the environment data transmission combination due to the fact that the actual collection information lacks the environment rainfall. The reason is that the video terminal 100 that has been illegally intruded does not obtain the distribution rule in the server 200, and therefore, a situation in which the transmission combination of the environmental data in the server 200 does not correspond to the target collection information will occur.
Step S09: and if the target acquisition information is not credible, outputting prompt information.
According to the above process of determining the target acquisition information, when the target acquisition information is not trusted, the video terminal 100 has a security hole of illegal intrusion. Therefore, in order to prevent a lawless person from attacking a corresponding video network through the illegally-invaded video terminal 100 or illegally stealing specific information of the monitoring environment, the server 200 outputs prompt information to prompt a manager to timely close a communication link between the server 200 and the video terminal 100. The process of outputting the prompt information by the server 200 may be similar to the prompt information output by the server 200 when the actual acquisition information output by the video terminal 100 is determined to be unreliable, and the specific output process is not described herein again.
When the security verification result of the target collection information is credible, the server 200 outputs the target collection information to the display 300, so that the manager can conveniently check the specific information of the environment.
The above is a description of an embodiment of a method for verifying security of video network transmission with environmental data, and the solution described in the present application is further described below by an embodiment of a system.
The application provides a video network transmission safety verification system with environmental data. The system includes a server 200 and a plurality of video terminals 100, each of the plurality of video terminals 100 being connected to the server 200.
