Embodiment Construction
[0043] The core of the present disclosure is to provide a multimedia conference data processing method.
[0044] After a terminal joins a multimedia conference, it always needs to transmit audio and video. The terminal that sends audio and video can be called the sending end, and the terminal that receives audio and video can be called the receiving end. After the sending end determines the audio and video stream to be sent, it can use the pre-generated audio and video encryption key to encrypt the audio and video frames in the audio and video stream to obtain the audio and video ciphertext frame. Or when the key encryption key is updated, the audio and video ciphertext frame is spliced with security information, including the ciphertext and key obtained by encrypting the audio and video encryption key with the pre-obtained key encryption key The encryption key version, based on the audio and video ciphertext frame, constructs audio and video data and sends it to the receivi...

The invention relates to a multimedia data processing method, a system, a device and a storage medium, and the method comprises the steps: a transmitting end carries out the encryption processing of a to-be-transmitted audio and video code stream through employing an audio and video encryption key after determining the to-be-transmitted audio and video code stream, constructs audio and video data based on an obtained audio and video ciphertext frame, and transmits the audio and video data to a receiving end; under the condition that the security information exists in the audio and video data, the receiving end obtains a key encryption key to be started according to a key encryption key version in the security information, obtains an audio and video encryption key through the key encryption key, decrypts an audio and video ciphertext frame in the audio and video data by using the audio and video encryption key, and obtains and outputs an audio and video code stream. By applying the method provided by the invention, the transmitted audio and video data is subjected to encryption protection, the audio and video encryption key is also protected, and the multimedia conference data is subjected to security processing, so that the security of the multimedia conference can be enhanced.
Description
technical field [0001] The present disclosure relates to the technical field of computer applications, in particular to a multimedia conference data processing method, system, device and storage medium. Background technique [0002] With the rapid development of computer technology and network technology, multimedia conferences such as audio and video are more and more widely used. Multimedia conferencing relies on the network and has the characteristics of high efficiency, low cost, fast and convenient. Users can join the multimedia conference through corresponding terminals. [0003] However, because the multimedia conference has a certain degree of privacy, the data of the multimedia conference also has privacy. If the data is lost, there may be risks such as confidential disclosure, and the security is low. In order to improve the security of the multimedia conference, how to safely process the data of the multimedia conference is a technical problem urgently needed to...
