DATA MONITORING METHOD, APPARATUS, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/039871
Kind Code:
A1
Abstract:
A data monitoring method, apparatus, device and system. A call control terminal encrypts a call key on the basis of user information of a client to obtain call key information, and forwards the call key to a client by means of a server, so that the client obtains the call key; the server obtains encrypted call content data transmitted during target call, and forwards the encrypted call content data to the client, so that the client decrypts the encrypted call content data by means of the call key to obtain call content data; the server sends the client a call key subjected to special encryption and used by encrypted data during call, so that the client can use the call key to decrypt the call content data encrypted during call, so as to obtain actually transmitted call content data. The special encryption ensures that only the client can decrypt an encryption key, that is, the monitoring during encrypted data transmission is realized, and the reliability of data transmission is improved.
