It is described in detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present invention.It should be understood that this
Locate described specific embodiment and be merely to illustrate and explain the present invention embodiment, is not intended to restrict the invention embodiment.
Fig. 1 is a kind of flow diagram of password identification method of the embodiment of the present invention, which is used for intelligence
Can lock end, and the smart lock is, for example, gate inhibition, shared vehicle, express delivery cabinet, the smart lock on intelligent electronic device.
As shown in Figure 1, the password identification method may comprise steps of:
Step S110 receives the password by key-press input.
Wherein, the key can be the physical button on smart lock, can also is in by the touch screen etc. of smart lock
Existing virtual key.
Wherein, the password can be numerical ciphers, letter code, password symbol etc. or combinations thereof, the embodiment of the present invention
It is not restricted to this.But the proper password of user's input is required to open the smart lock.
Step S120, in response to the input of the password, the detection interval time of key and/or calculating twice inputs close
Correlation between code and the proper password prestored.
Wherein, key refers to the key twice of the user in the button operation for once inputting the password twice.
Step S130 is less than preset normal interval time and/or the correlation less than default in the interval time
Threshold value when, determine input password be malice password.
Here, step S120 and step S130 is two features designed by two features for malice password are as follows:
(1) timeliness
When user inputs proper password, it can be thought deeply, and pay close attention to key position, to be had between key twice certain
Time interval, but malice password is typically all stochastic inputs, has the characteristics that rapidly input.Therefore when can be according to key
Between interval to judge, if twice the interval time of key be less than normal interval (such as 100ms), can determine that its for malice it is close
Code.
In a preferred embodiment, the timer that can be triggered with configuration response in the button operation of user, by described
Timer detects the interval time of user's key twice.
(2) correlation
There are two types of possible for meeting when inputting password by user: first is that the case where corresponding proper password, i.e., known correct
Password is inputted in the case where password；Second is that the case where corresponding malice password, in the case where unknown password, random or exhaustion is defeated
Enter password.
The password of both of these case input has larger difference, and the password inputted in the case of the first is related to proper password
Property it is very strong, the password and proper password correlation of second situation input be very poor, therefore according to the password of input and can prestore
Correlation between proper password determines malice password, will determine to use when calculated correlation is less than preset threshold value
The password of family input is malice password.
In a preferred embodiment, the method for calculating the correlation may include: in the password of input described in comparison
Character in character and the proper password, using identical character number divided by the character number of the proper password value as
The correlation.Wherein, preset threshold value is, for example, 50%, that is, shows the character and proper password that have 50% in the password of input
It, all cannot malice password at last when identical.
For example, it is assumed that proper password is ABCD (wherein Any Digit is likely to be duplicate in A, B, C, D), then base
In the calculation method of above-mentioned correlation, non-malicious password can have following several situations:
1) omit combination: leakage presses or not by a upper A/B/C, the result is that BCD/ACD/ABD, at this moment without unlocking sound
Sound, user may at will press one again, and after mistake, user restarts new round key.So the BCDX/ generated therewith
ACDX/ABDX cannot can be regarded as malice password.
2) even key combination: any one key is continuously pressed once, the result is that AABC/ABBC/ABCC more.In this case,
It might have the prompting of " Password Input mistake ", so that user restarts new round key.So AABC/ABBC/ABCC, no
Malice password can be can be regarded as.
3) missed keys: some key do not remember, or by inclined, mistake occurs, may combination such as X (non-A) BCD/AX
(non-B) CD/ABX (non-C) D/ABCX (non-D).
In this way, by comparing the character in the character and the proper password in the password of user's input, and calculate accordingly
Correlation can make the situation of above-mentioned omission combination, company's key combination and missed keys is not misjudged to break as malice password.At other
Embodiment in, can also since the first character, compare in order user input password character and proper password in
Corresponding character, then using identical character number divided by the value of the character number of the proper password as the correlation, it is this
Method is more favorable for guaranteeing the accuracy of Password Input.
