Referring to fig. 2, the present invention provides a video conference control method, in an embodiment of the video conference control method, the video conference control method includes the following steps:
step S10, when detecting that the video conference software in the terminal is started, determining whether the data cache space of the video conference software in the terminal is an encrypted cache space;
in this embodiment, the terminal may include a mobile phone, a tablet computer, a personal computer, and the like. However, in order to improve the security included in the video conference information, at least one piece of video conference software needs to be installed in the terminal, and when the video conference software is installed on the terminal device of the user, such as an office computer, a personal computer, a mobile terminal, and the like, it needs to determine whether the video conference software is the video conference software with a higher importance level, if so, an individual and encrypted data cache space is allocated to the video conference software, and the data cache space is encrypted by using a key to obtain the encrypted data cache space.
That is, before the video conference, whether the installed video conference software in the terminal meets the preset encryption requirement is detected, that is, whether the importance level of the video conference software (which can be determined according to the number of times of use by the user or the level degree set by the user) is higher than the preset value is determined, if so, the video conference software meets the preset encryption requirement is determined, at this time, the video conference software is considered to be important, a separate data cache space needs to be given to the video conference software for distinguishing from the data of other software, a first secret key (namely, a secret key containing server information) sent by a server corresponding to the video conference software is obtained, the data cache space is encrypted for the first time according to the secret key, and the data cache space after the first encryption is encrypted for the second time according to the software information of the video conference software itself, and using the data cache space after twice encryption as an encryption cache space.
Therefore, when detecting that the video conference software is triggered and started in the terminal, it may be determined whether the started video conference software is the video conference software with the importance level higher than the preset value, and if so, it may be determined that the data cache space of the started video conference software in the terminal is the encrypted data cache space, and the started video conference software may be continuously used only by decrypting the encrypted cache space. However, if the importance level of the video conference software which is sent is lower than or equal to the preset value, it is determined that the data cache space of the video conference software which is sent is not the encrypted data cache space, and the video conference software can be directly adopted to carry out the video conference operation without carrying out the decryption operation.
Step S20, if yes, a key corresponding to the video conference software is obtained, and the encrypted cache space is decrypted according to the key to obtain a decrypted cache space;
when the data cache space of the video conference software in the terminal is found to be the encryption cache space through judgment, the key of the video conference software during encryption needs to be acquired, that is, the first key and the second key need to be obtained, the first key may be obtained by the way that the videoconference software sends a key request instruction to the server, the server performs authentication according to the key request instruction, when the verification is passed, the first secret key is sent to the video conference software, the video conference software decrypts the encrypted cache space according to the first secret key and a second secret key of the video conference software to obtain a decrypted cache space, the method comprises the steps of firstly decrypting an encrypted cache space according to a second key of video conference software to obtain a primary data cache space, and then decrypting an initial data cache space according to a first key to obtain a decrypted data cache space, namely a decrypted cache space. That is, when receiving an instruction of a user to run the video conference software, that is, when the user opens the video conference software, the key used in the previous encryption and the decryption algorithm corresponding to the encryption algorithm are loaded first, and the encrypted data cache space is decrypted. The video conferencing software can use this buffer space normally, including reading and writing data to the buffer space.
It should be noted that before the key of the video conference software is obtained during encryption, the participants participating in the video conference need to be verified, that is, the camera function of the terminal is started through the video conference software, the face images of the participants participating in the video conference are collected through the camera, then the face images are subjected to feature recognition, that is, the face images are subjected to face recognition, the recognized face features are compared with the account information preset in the video conference software, whether the target account information is matched with the face features is determined, that is, whether the recognition result of the feature recognition is matched with the account information corresponding to the video conference software is detected, if the recognition result is matched with the account information, the key corresponding to the video conference software can be directly obtained, but if the recognition result is not matched with the target account information, prompt information of a verification error is output, and the operation of obtaining the key is stopped.
And step S30, acquiring the audio and video data sent by the server corresponding to the video conference software, storing the audio and video data in the decryption cache space, and outputting the audio and video data in the decryption cache space.
After the encrypted cache space is decrypted, audio and video data (namely, audio data and video data) transmitted by a server corresponding to video conference software are obtained, the audio and video data are stored in the decrypted cache space, a terminal can actively acquire the audio and video data from the decrypted cache space to output, namely, after the video conference software carries out a video conference, the audio and video data pulled from a network (namely, the server) by the terminal are stored in the decrypted cache space, and the terminal can call a display and a loudspeaker to play the audio and video data, so that a normal video conference is realized. And other third-party screen recording software cannot decrypt the audio and video data in the cache space, cannot read the audio and video data in the decrypted cache space, and cannot store the audio and video data additionally because of no secret key, so that the video conference is prevented from being recorded.
When the video conference software carries out a video conference, whether third-party software reads audio and video data in the decryption cache space needs to be detected in real time, when the third-party software reads the audio and video data through judgment, whether the third-party software carries a secret key for unlocking the encryption cache space needs to be determined, and if the third-party software does not read the audio and video data in the decryption cache space, the third-party software is directly forbidden to read the audio and video data. And this embodiment can be applied to in the wisdom security protection field, carries out safety protection through the audio and video data when carrying out the videoconference to video conferencing software to also promoted the construction in wisdom city, this embodiment belongs to the wisdom security protection field moreover, can promote the construction in wisdom city through this embodiment.

When the video conference software is started and the data cache space in the terminal is the encryption cache space, the key is required to be acquired first to decrypt the encryption cache space to obtain the decryption cache space, then the acquired audio and video data are stored in the decryption cache space, and the audio and video data in the decryption cache space are output, so that the phenomenon that information leakage occurs due to the fact that information exchange is directly performed by a video conference in the prior art is avoided, and the safety of video conference information is improved.
