Third step history average: system calculates nearly 5 years (or 10 years) monthly automatically, and (or season, time can voluntarily set
Set) history average (being denoted as Y)；
4th step compares professional standard value, history average and expertise value, confirms threshold value.System compares row automatically
Industry standard value and history average are minimized as preliminary threshold.Preliminary threshold and expertise value are compared again, if waiting
In expertise value, then threshold value is expertise value, if more than or less than expertise value, then pops up preliminary threshold and expert's warp
The numerical value of value is tested, and marks and pays the utmost attention to expert's value, by the final numerical value of user's threshold value.
In public health geodata Input Process, first check whether new typing public health geodata is marked
Private data then compares new typing public health geodata with threshold value if the data of secret protection need to be gone: if new
Typing public health geodata is less than threshold value, then new typing public health geodata is never desensitized store in database to
It desensitizes database (first carrying out secret protection to handle)；If new typing public health geodata is greater than or equal to threshold value, no
It stores to desensitization database.
If unmarked new typing public health geodata is secret protection, new typing public health geodata is deposited
Storage extremely desensitization database.
