Stop touching.
As shown in Fig. 2, being based on said system, a kind of fingerprint authentication method for safe cabinet is also proposed in the present embodiment,
Comprise the following steps:
S1, typing finger print information；
S2, presets n digit fundamental cryptographics, N1, N2, Nn（n<10）；
S3, setting time threshold values M；
S4, sets time password K, K1=M+N1, K2=M+N2 ... Kn=M+Nn of n digits, or K1=M-N1, K2=M-N2 ...
Kn=M-Nn;
S5, verifies finger print information, is proved to be successful into S6；
S6, the finger print information that the corresponding time is sequentially input according to the preset time value of preset time password are verified.
N digit time passwords are calculated with benchmark password in passage time threshold values M, and user is after time password is set up
Time by touching fingerprint collecting equipment sequentially inputs n time passwords and is verified, and time threshold can be changed so that
Time password is variable, and security higher, it is big to crack difficulty.S6 be proved to be successful after may be selected unlocking instruction, modification time threshold values with
And modification fundamental cryptographic, can directly it unlock or Modify password, it is easy to operate.
Each time password is verified successively in S6 steps, shows and tests after last time password has been verified
Demonstrate,prove result.Since time password has n, to each progress individual authentication and after the completion of being verified to last time password
Verification result is exported, just display as a result, make it can not learn that mistake occurs in who password, increases thief after input n is password
Add and crack difficulty.
Such as user setting fundamental cryptographic is 123456, setting time threshold is M=10, and it is M- to set time password algorithm
N, gained time password be 987654, user verification when need to touch finger print acquisition module successively 9 seconds, 8 seconds, 7 seconds, 6 seconds, 5 seconds,
4 seconds, you can input time password, time showing module 7, which can accurately be shown, touches the time, is unclamped easy to user in correct time
Finger.After last time password has been verified（4）Verification result is exported, since this method need to touch fingerprint collecting mould repeatedly
For block 1 according to time showing module 7 input time password, thief need to obtain user fingerprints information and time password letter at the same time
Breath, difficulty bigger, security higher.
Further, the coded lock being used cooperatively with above-mentioned password validation system is additionally provided with, which can use city
General coded lock on face, the switch for the carrier that coded lock and Fingerprint Lock co- controlling are encrypted, user verified fingerprint with
And need just open coded lock opening by protection carrier, security higher after time password.
This specific embodiment is only explanation of the invention, it is not limitation of the present invention, people in the art
Member as needed can make the present embodiment the modification of no creative contribution after this specification is read, but as long as at this
All protected in the right of invention be subject to Patent Law.
