Effect of the invention is described further below with reference to emulation experiment.
1. emulation experiment condition:
Condition 1, in Intel (R) Celeron (R) G540 processor, 7 Ultimate operating system of Windows it is desk-top
The result that test emulation is tested on computer.
Condition 2 is connect with Mozilla Firefox browser (version number 47.0.1.6018) in-service units on computers
By realizing Navigator.getUserMedia () function on mouth, starting microphone obtains audio file, when user need to use wheat
When gram wind carries out the second factor authentication, this function will be activated.
2. emulation experiment content and interpretation of result:
Emulation experiment of the invention is to do login test respectively in quiet indoor environment and noisy outdoor environment.
Environment indoors, for emulation experiment of the invention by setting sound source number N=1, sound source is music player, with
This simulates indoor environment.
Under outdoor environment, for emulation experiment of the invention by setting sound source number N (N > 1), sound source is music
Device simulates outdoor environment with this.
In experiment, Lm is set by the distance of mobile phone terminal and computer end microphone, sets Ts for record length, by environment
Sound similarity threshold is set as Sm。
Under indoor environment, 1 is set by sound source number N, to obtain different distance Lm and record length Ts and average sound
Relationship between sound similarity value S, emulation experiment of the invention have carried out 427 registers.
Using the ambient sound data being collected into, use environment sound similarity calculating method calculates every a pair of of sound number
According to ambient sound similarity value, average to obtained ambient sound similarity value, obtain table 1.L indicates mobile phone in table 1
Hold distance of the microphone to computer end microphone, unit: rice (m)；T indicates to record the time of ambient sound, unit: second (s).
Table 1: average environment sound similarity list unit: %
From table 1, it can be found that following rule: record length T is longer, and average Voice similarity value S is bigger.Mobile phone terminal Mike
The distance L of wind to computer end microphone is remoter, and average environment sound similarity value S is smaller.Record length is longer, mobile phone terminal Mike
Influence of the distance L to average Voice similarity value S of wind to computer end microphone is smaller.

Experiment discovery can satisfy convenience and require and have ideal average similarity value S, at this time hand as record length T=4s
Influence of the distance L to average similarity value S of generator terminal microphone to computer end microphone is also smaller, then in following emulation
4s is set by record length T in experiment.
Under outdoor environment, sound source number is set N (N > 1) by emulation experiment of the invention, sets record length T to
4s, this experiment have carried out 3246 registers.
Using the ambient sound data being collected into, use environment sound similarity calculating method obtains its respective ambient sound
Sound similarity value.
Take sound source number N=1, experimental data when 3,6,9 is arranged, and Fig. 2 is obtained.Abscissa indicates mobile phone in Fig. 2
Hold the distance L of computer end, unit: rice.Ordinate in Fig. 2 indicates average environment sound similarity value S.With diamond shape in Fig. 2
The curve of mark indicates to obtain average environment sound similarity curve when sound source number N=1；With the song of square mark in Fig. 2
Line indicates to obtain average environment sound similarity curve when sound source number N=3；Sound is indicated with the curve that triangle indicates in Fig. 2
Average environment sound similarity curve is obtained when the number N=6 of source；Sound source number N=9 is indicated with the curve that fork-shaped indicates in Fig. 2
When obtain average environment sound similarity curve.
It is found from Fig. 2, the average environment sound similarity value S of each curve is slowly reduced within distance 5m.Sound source number N
More, average environment sound similarity value S reduces faster other than 5 meters of distance.
For the safety of the verification process of dual factors rapid authentication method of the raising based on ambient sound, remotely attacked with resisting
It hits, by ambient sound similarity threshold values SmIt is set as 95%, can either guarantee the success rate of user log-in authentication, can also be guaranteed
The safety of process of user login.
