Value, and the corresponding information index value of user identity information of different user is different.
Table one:
In the application, the information index value that electronic equipment generates has impact resistance and randomness.Wherein, impact resistance is used
In preventing duplicate information index value.Randomness is for avoiding camouflage and exhaustion verification, i.e. raising information index value is by mould
Difficulty that is imitative and decoding.
Optionally, generate the corresponding information index value of user identity information, comprising: calculate current time and preset time it
Between difference；Difference and presetting digit capacity are inputted into preset index value and generate formula, obtains information index value.Wherein, difference with
The product of concurrency maximum value is less than or equal to 2i, i is presetting digit capacity.
Wherein, it is as follows to generate formula for preset index value:
Information index value=((current time-preset time)/10k-k’) %2i
K is the decimal digits of current time timing accuracy, such as: current time timing accuracy is Millisecond, then small
Numerical digit number is 3, k 3.The maximum value of concurrency is default in the electronic device, and the maximum value of the concurrency refers to synchronization
