The embodiment of the invention also provides a method for safely processing the epidemic situation propaganda video data. Fig. 1 is a first flowchart of a security processing method for epidemic situation promotion video data according to an embodiment of the present invention, which may include the following steps:
s21, sending a network connection verification request to the target terminal.
In S21, the network connection verification request is used to indicate that the verification result of the first set message length generated by the target terminal needs to meet the data security requirement, and the network connection verification request includes a random message of the second set message length, a current time slice thread of an epidemic situation propaganda platform of the third set message length, longitude and latitude information and a first numerical value of the first verification point, and a second numerical value of the second verification point; the value of the first verification point at the specified position of the verification result is a first numerical value, and the specified position is longitude and latitude information of the first verification point.
And S22, receiving network connection feedback information sent by the target terminal and real-time longitude and latitude information of the terminal, and generating a network connection verification private key according to the current time slice thread and the real-time longitude and latitude information.
In S22, the network connection feedback information includes the following information: and the verification result meeting the data security protection requirement and the corresponding terminal time slice thread when the target terminal processes the network connection verification request.
S23, splicing the random message and the terminal time slice thread to obtain target data when the verification result meets the data security protection requirement; encrypting the target data according to the network connection verification private key to obtain data security verification parameters; and judging whether the data security verification parameters are the same as the verification result, if so, determining that the target terminal passes the data security verification and establishing network connection with the target terminal.
S24, when an uploading request aiming at a video image collected by a target terminal and sent by the target terminal is received, determining the distribution authority of the time slice resource occupancy rate of the epidemic situation propaganda platform; if the distribution authority represents that the epidemic situation propaganda platform is in a distribution state, acquiring a video image based on a network connection channel; if the distribution authority indicates that the epidemic situation propaganda platform is in a non-distribution state, establishing a cache channel with the target terminal, and acquiring a video image based on the cache channel;
s25, filtering the video image to obtain a first target video image; denoising the first target video image to obtain a second target video image; performing back tracing processing on the second target video image to obtain a third target video image; and storing the third target video image.
Through S21-S23, before the epidemic situation propaganda platform establishes network connection with the target terminal, whether the target terminal passes through data security verification or not can be determined based on the sent network connection verification request, the received network connection feedback information and the real-time longitude and latitude information, and the network connection is established when the target terminal passes through the data security verification.
Through S24, different channels can be adopted to obtain the video image of the target terminal according to the distribution authority of the time slice resource occupancy rate of the epidemic situation propaganda platform, the package falling and dislocation of the video image at the image frame level and the time thread level can be avoided, and the accuracy and reliability of the received video image are ensured.
Through S25, the received video image can be successively filtered, denoised and returned to be traced, so that the storage efficiency of the epidemic situation propaganda platform is improved, the system breakdown caused by overload of the storage load of the epidemic situation propaganda platform is avoided, and the operation reliability of the epidemic situation propaganda platform is ensured.
It can be understood that through S21-S25, the dimensionality of data security protection, video image receiving and video image storage can be optimized respectively, and therefore the operation reliability of the epidemic situation propaganda platform is guaranteed.
It can be understood that in S24, since the received video image is obtained through the network connection channel and the buffer channel, a problem of intersection or overlapping of the network connection channel and the buffer channel may occur during video image transmission, thereby causing a blending of the received video image, and therefore, it is necessary to filter the blended video in the video image. To this end, referring to fig. 2, in S25, the video image is filtered to obtain a first target video image, which may specifically include the following:
and S2511, determining a blending video in the video image.
In S2511, at least two adjacent target image frames exist in the blended video, and the modulus of the difference between the feature vectors of the two target image frames exceeds a set value. Specifically, the set value may be determined from an average value of mode values of feature vectors of two target image frames.
S2512, setting a margin channel in the original filtering thread, setting the margin channel as a target channel, and activating the target channel.
S2513, when the offset filtering thread needs to read the activated target channel, configuring a channel query channel in the original filtering thread, and acquiring the time when the channel query channel is configured as the initial time.
S2514, after the margin channel is activated, the channel query channel is switched to an open state.
S2515, determining whether the channel query channel is in a ready state, if the channel query channel is in the ready state, determining that the target channel is successfully read, and obtaining the time when the target channel is successfully read as the current time.
S2516, filtering the amalgamated video based on the target channel.
S2617, confirm the absolute value of the difference between the initial moment and the current moment, and determine the absolute value as the filtering time consumption.
S2518, judging whether the filtering time exceeds a preset time; when the filtering time consumption exceeds the preset time length, outputting prompt information for representing that the video image is filtered to be abnormal, and stopping the process of receiving the video image from the target terminal; and when the filtering time does not exceed the preset time, determining that the process of filtering the video image is normal.
Through S2511-S2516, under the condition that the channel congestion is caused by a large number of mixed spliced videos, a default filtering channel can be avoided, and whether the target channel is read successfully or not can be determined based on a margin channel set in an original filtering thread and a configured channel query channel, so that the mixed spliced videos are filtered according to the target channel, the mixed spliced videos can be successfully filtered, and the blockage during the filtering of the mixed spliced videos is avoided.
Through S2517-S2518, whether the process of filtering the video image is in a normal state can be determined, when the video image is filtered and is abnormal, prompt information is output and the process of receiving the video image from the target terminal is stopped, so that the phenomenon of packet loss caused by continuous receiving of the video image during filtering can be avoided, and the reliability of filtering the blended video is improved.
Since the blended video is determined based on the set value, there may be a situation of "one cut" in the process of obtaining the blended video, and more specifically, even if the blended video is filtered to obtain the first target video image, signal disturbance may be generated in the filtering process, which may cause noise to appear in the first target video image, thereby causing distortion of the first target video image, for this reason, referring to fig. 3 in combination, in S25, the first target video image is denoised to obtain the second target video image, which specifically includes the following contents:
s2521, counting the first target video images to obtain a first target video image set.
