And the association module carries out association processing on the two electronic discs to form associated electronic discs, and divides each electronic disc into at least two storage areas according to the storage positions.
The acquisition module acquires authentication identity information of an operator when one of the electronic discs performs data transmission and storage, and acquires operation behavior information of the operator when the electronic disc performs data storage.
The analysis module performs joint processing analysis on the user authentication identity information and the operation behavior information when the electronic disk performs data transmission storage to obtain a use security value; the use security value comprises an identity authentication value and an operation behavior value, wherein the identity authentication value is a numerical value which is obtained by processing and analyzing user authentication identity information when the electronic disk is used for data transmission and storage and is used for representing user authentication identity, and the operation behavior value is a numerical value which is obtained by processing and analyzing user operation behavior information when the electronic disk is used for data transmission and storage and is used for representing user operation behavior.

It should be noted that here, the values of a1 and a3 are 10, the value of a2 is 1, and the behavior function is used when the value of the number of times of exiting the storage area TCZ is 3, the value of the time length of stay of the storage area TSZ is 10, and the value of the number of times of shifting the storage area YCZ is 1Calculating to obtain an operation behavior value CZZ of 50; in the case that the number of times of exiting the storage area is 1, the value of the time length of stay of the storage area is 20, and the value of the storage data shift storage area is YCZ is 1, the data is obtained by a behavior functionThe calculated operational behaviour value CZZ is 40.
By a safety functionA safety in use value SYA is calculated, wherein b1 and b1 are adjustment factors and are greater than zero.
It should be noted that, here, b1 has a value of 10, b2 has a value of 1, and when the authentication value SFZ has a value of 6 and the operation behavior value CZZ has a value of 50, the operation is continuedOversafety functionThe use security value SYA is calculated to be 10, and when the value of the identity authentication value SFZ is 10 and the operation behavior value CZZ is 40, the use security value SYA is calculated by a security functionThe calculated use security value SYA is 60.
