step S41: calculating a release safety coefficient of the release; the safety coefficient indicates the platform serverAnd the safety of data transmission and data delivery between delivery terminals; specific: calculating a safety factor S based on the following formulas (1) - (4); wherein: in is the access terminal number of the delivering terminal; oa (Oa) in Is the security coefficient of the in-th access terminal; o (O) o Is the safety coefficient of the terminal; TO in Is the access amount of the in-th access terminal; pmtS1 is the maximum access amount of the delivery terminal; p1 is the transmission path security level; avT is the average storage time length of the put data in the put terminal; allowable storage duration of pmt put-in data; PT is a transmission path security threshold of p 1; a1 and a2 are weight coefficients; a3, a4, and a5 are equilibrium coefficients; EV is a constant value;
step S42: selecting different safety processing modes based on the release safety coefficient; carrying out safe processing on the put-in data to obtain target data;
step S5: the target data is sent to the delivery terminal; the delivery terminal obtains delivery data by executing the same safe processing mode on the received target data based on the first multimedia data or the second multimedia data sent by the delivery terminal; the same security process is the inverse of the security process as or similar to step S4.
2. The data security control method of claim 1, wherein the first terminal or the second terminal is one or more.
3. The data security control method of claim 2, wherein the multimedia data comprises audio, video, text or/and image data.
4. A data security control method according to claim 3, wherein the platform server is an online education platform server.
5. The data security control method of claim 4, wherein the platform server obtains the third multimedia data locally.
6. The data security control method according to claim 5, wherein the access amount is a time length of access or an amount of data transmitted at the time of access.
7. A data security control platform comprising a processor coupled to a memory, the memory storing program instructions that when executed by the processor implement the data security control method of any of claims 1-6.
8. A computer readable storage medium comprising a program which, when run on a computer, causes the computer to perform the data security control method according to any one of claims 1 to 6.
9. A data security control system, characterized in that the system is configured to perform the data security control method according to any of claims 1-6.
