Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The method for unlocking process flow diagram that is illustrated in figure 1 a kind of multiple lock that the embodiment of the present invention provides, the method comprises the following steps:
S102, setting initial trust degree coefficient value.
Preferably, this step further comprises: regularly studying history authenticates case, and the high period of the frequency of unblanking is set as to the focus period, according to current time, whether at focus, basic degree of belief coefficient value is set in the period.
Specifically, all previous all acts of authentication and authentication result of unblanking that history has authenticated case history, after multiple lock opening anti-theft device, from database, read all cases of unblanking, analysis draws the highest time period of success ratio of unblanking, and be set as authenticating the focus period, with this, initial trust degree coefficient value is at that time set.When acts of authentication starts to carry out, its degree of belief coefficient is initial trust degree coefficient value for this reason.Trusted coefficient is different and different according to setting, and such as adopting per half an hour to reset initial trust degree coefficient value one time, if there was at that time unlocking person carrying out acts of authentication, puts off next period setting.
S104, often receive after the authentication result of an acts of authentication, according to authentication result, adjust current degree of belief coefficient value.
Specifically, acts of authentication can be any one authentication mode in multiple lock, includes but not limited to: magnetic card authentication, finger print identifying, cipher authentication or mobile phone authentication.If acts of authentication success, promotes degree of belief coefficient; If acts of authentication failure, reduces degree of belief coefficient.
As a kind of preferred version of this step, the degree-of-difficulty factor that can authenticate link in conjunction with each is adjusted current degree of belief coefficient value in real time, if i.e.: acts of authentication success promotes degree of belief coefficient value according to the degree-of-difficulty factor of current authentication; If acts of authentication failure, reduces degree of belief coefficient value according to degree-of-difficulty factor value average.
Wherein, according to the degree-of-difficulty factor of current authentication, promoting degree of belief coefficient further comprises: the long-pending amplification according to the degree-of-difficulty factor value of amplification coefficient and current authentication promotes; According to the degree-of-difficulty factor value of current authentication, reducing degree of belief coefficient further comprises: the long-pending range of decrease that deducts degree-of-difficulty factor value and range of decrease coefficient according to range of decrease number reduces.
Another kind of preferred version as this step, when acts of authentication success, can also be accustomed to adjusting in real time current degree of belief coefficient value in conjunction with the authentication sequence of unlocking person, that is: when the order authenticating is consistent with historical success identity case, according to successful frequency values, promote degree of belief coefficient value; When inconsistent, do not adjust degree of belief coefficient value.Wherein, according to successful frequency values, promoting degree of belief coefficient value further comprises: the long-pending amplification according to similar degree amplification coefficient and similar ratio value promotes degree of belief coefficient value.
S106, calculating trust degree value.
Specifically, trust degree value is the foundation for whether judgement is unblanked legal.Calculating trust degree value further comprises; According to working as the degree-of-difficulty factor of time authentication result, authentication mode and the trust degree weights that degree of belief coefficient calculations is worked as time acts of authentication, and the trust degree weights of the each acts of authentication of accumulative total, trust degree value obtained.
For instance, can adopt the weights that calculate each authentication link, then add up and obtain trust degree value, specifically adopt following formula to calculate:
Wherein, m represents the quantity of the authentication mode of employing; N represents the numbering of every kind of authentication mode; AuthDifficult
nthe degree-of-difficulty factor that represents n kind authentication mode; Belief
nbe illustrated in the degree of belief coefficient carrying out after the success of n kind authentication mode; AuthState
nwhether the authentication that represents n kind authentication mode success status, during success, is 1, is 0 when unsuccessful.
S108, judge whether current trust degree value surpasses default release threshold value or lower than default alarm threshold value, if so, execution step S110, otherwise execution step S112.
Specifically, by judging trust degree value judges whether unlocking person is owner, if when trust degree value is greater than default release threshold value (such as being set as 1.0), carry out release action; If trust degree value during lower than default alarm threshold value (such as being set as 0.1), is carried out actuation of an alarm; Trust degree value between default alarm threshold value and default release threshold value time, needs to proceed other authentication modes, until complete all authentication modes, or trust degree value is greater than default release threshold value or lower than default alarm threshold value.
S110, when trust degree value surpasses default release threshold value, send unlocking signal to carry out release; When trust degree value is during lower than default alarm threshold value, send alerting signal and report to the police to carry out.
S112, judged whether all authentication modes, if so, performed step S114, otherwise return to step S104.
S114, transmission alerting signal are reported to the police to carry out.
The method for unlocking of the multiple lock that the embodiment of the present invention provides, combine multiple authentication mode, by analyzing the acts of authentication of unlocking person, comprise by key element real-time judge trust degrees such as authentication success rate and authentication sequence, whether be legal unblank carry out release or warning, thereby reach safe and convenient anti-theft effect if needn't open that all locks just can identify.
The process flow diagram of the examples of many successful of unblanking of a kind of multiple lock provided by the invention as shown in Figure 2, suppose and have 4 authentication modules, the degree-of-difficulty factor of its authentication module is followed successively by respectively 0.6,0.5,0.5 and 0.4, initial trust degree coefficient value is 0.6, degree of belief coefficient amplification coefficient is 0.8, and range of decrease coefficient is 0.3.The default release threshold value setting is 1.0, and warning degree of belief threshold value is 0.1, and supposes all successes of each acts of authentication, and the method comprises the following steps:
S202, initialization degree of belief coefficient value.
Being about to degree of belief coefficient value and being set as initial value, by application scenarios above, is 0.6 in the present embodiment.
S204, reception acts of authentication.
S206, promote degree of belief coefficient value in real time, calculate trust degree value.
Because this authentication result is successfully, can be that parameter calculates this amplification value according to the degree-of-difficulty factor of this authentication mode, be added on trusted coefficient value.Computing formula is as follows:
The degree-of-difficulty factor value of this amplification=amplification coefficient * authentication module.
Specifically, when user's selective authenticate module 1 success identity, according to above computation model, * 0.6 (degree-of-difficulty factor)=0.48, this amplification=0.8 (amplification coefficient), degree of belief coefficient value after renewal is 0.6 (trusted coefficient value)+0.48 (this amplification)=1.08, and the trust degree value of this acts of authentication is 0.6 (degree-of-difficulty factor) * 1.08 (trusted coefficient value)=0.648.
During user's selective authenticate module 2 success identity, * 0.5 (degree-of-difficulty factor)=0.4, this amplification=0.8 (amplification coefficient), degree of belief coefficient value after renewal is 1.08 (amplification)=1.48, (trusted coefficient value)+0.4, the trust degree value of this acts of authentication is 0.5 (degree-of-difficulty factor) * 1.48 (trusted coefficient value)=0.74, and accumulative total trust degree value is now 0.648 (the trust degree value of module 1)+0.74 (the trust degree value of module 2)=1.388>1.0 (default release threshold value).
So far, accumulative total trust degree value is greater than default release threshold value, does not follow-uply need user further to operate authentication module 3 and authentication module 4.
S208, act of authentication is analyzed, further promoted trusted coefficient value, calculate trust degree value.
Specifically, this step reads with this acts of authentication order and similarly authenticates case from data base, calculates the ratio of number of success, if ratio is greater than similar degree threshold value (being 0.6 in the present embodiment), promotes degree of belief coefficient value:
The similar ratio value of amplification=similar degree amplification coefficient *.
Wherein, similar degree amplification coefficient is 0.2, if user is successfully completed the authentication of authentication module 1 and module 2, and in the historical case of the authentication of storing in database, having with it similarly ratio is 0.7, amplification is 0.2 (similar degree amplification coefficient) * 0.7 (similar ratio)=0.14, and the degree of belief coefficient after renewal is 1.48+0.14=1.62.The trust degree value of this authentication is 1.62*0.5=0.81.Accumulative total trust degree value is 0.648+0.81=1.458>1.0 (default release threshold value).
So far, accumulative total trust degree value is greater than default release threshold value, does not follow-uply need user further to operate authentication module 3 and authentication module 4.
S210, judge whether trust degree value is greater than default release threshold value, if so, performs step S212, otherwise return to step S204.
S212, transmission unlocking signal are to carry out release.
S214, preserve this verification process.
This step, by record the case of unblanking at every turn, offers follow-up analysis foundation of unblanking authentication as basic data.
The method that the embodiment of the present invention provides, by analyzing the acts of authentication of unlocking person, and in conjunction with the historical real-time accumulated trust degree of case of unblanking, needn't open all locks just can identified identity and release, thereby reaches safe and convenient anti-theft effect.
The process flow diagram of the failure example of unblanking of a kind of multiple lock provided by the invention as shown in Figure 3, there are 4 authentication modules in same supposition, the degree-of-difficulty factor of its authentication module is followed successively by respectively 0.6,0.5,0.5 and 0.4, initial trust degree coefficient value is 0.6, degree of belief coefficient amplification coefficient is 0.8, and range of decrease coefficient is 0.3.The default release threshold value setting is 1.0, and warning degree of belief threshold value is 0.1, and supposes to have and successfully also have failure in acts of authentication, and the method comprises the following steps:
S302, initialization degree of belief coefficient value.
Being about to degree of belief coefficient value and being set as initial value, by application scenarios above, is 0.6 in the present embodiment.
S304, reception acts of authentication.
S306, adjust degree of belief coefficient value in real time, and calculate trust degree value.
When authentication success, promote degree of belief coefficient, when authentification failure, reduce degree of belief coefficient, wherein, this range of decrease=(1-degree-of-difficulty factor value) * range of decrease coefficient.
Lift an example:
During user's selective authenticate module 1 success identity, * 0.6 (degree-of-difficulty factor)=0.48, this amplification=0.8 (amplification coefficient), degree of belief coefficient value after renewal is 0.6 (amplification)=1.08, (trusted coefficient value)+0.48, now, the trust degree value of this acts of authentication is 0.6 (degree-of-difficulty factor) * 1.08 (trusted coefficient value)=0.648.
Then continuous 5 authentification failures of user's selective authenticate module 2, according to authentification failure computation model, this range of decrease=(1 – 0.5 (degree-of-difficulty factor)) * 0.3 (range of decrease coefficient)=0.15, the degree of belief coefficient value after renewal is 1.08-0.15*5=0.33.
Then continuous 2 authentification failures of user's selective authenticate module 4, according to authentification failure computation model, this range of decrease=(1 – 0.4 (degree-of-difficulty factor)) * 0.3 (range of decrease coefficient)=0.18, the degree of belief coefficient value after renewal is 0.33-0.18*2=-0.03.Intelligent analysis module is analyzed degree of belief coefficient value and is less than degree of belief coefficient alarm threshold value (0.1), reports to the police.
Lift again an example:
When user's selective authenticate module 1 authentification failure, according to authentification failure computation model, this range of decrease=(1 – 0.6) * 0.3=0.12, the degree of belief coefficient value after renewal is 0.48.
Then user's selective authenticate module 2 authentication successs, according to authentication success computation model, this amplification=0.5*0.8=0.4, the degree of belief coefficient value after renewal is 0.48+0.4=0.88, trust degree=0.88*0.5=0.44.
Then user's selective authenticate module 3 authentification failures, according to authentification failure computation model, this range of decrease=(1 – 0.5 (degree-of-difficulty factor)) * 0.3 (range of decrease coefficient)=0.15, the degree of belief coefficient value after renewal is 0.88-0.15=0.73.
Then user's selective authenticate module 4 authentication successs, according to authentication success computation model, the degree of belief coefficient value after upgrading is 1.05, trust degree value is 0.4*1.05=0.42.
Calculate accumulative total trust degree value=0.44+0.42=0.86, because all authentication modes all taste, but user's accumulative total trust degree value does not reach release threshold value yet, is considered as illegal acts of authentication, reports to the police.
Step S308: judge that trust degree value, whether lower than default alarm threshold value, if so, performs step S312, otherwise execution step S310.
Step S310: judged whether all authentication modes, if so, performed step S312, otherwise returned to step S304.
Specifically, attempted after all authentication modes, trust degree value still, lower than default release threshold value, is considered as the behavior of extremely unblanking, and reports to the police.
S312, transmission alerting signal are reported to the police to carry out.
Specifically, according to warning demand, can carry out various alarms, as sound and light alarm, SMS alarm, take pictures etc.
S314, preserve this verification process.
The method that the embodiment of the present invention provides, by analyzing the real-time accumulated trust degree value of acts of authentication of unlocking person, when trust degree value is during lower than default alarm threshold value or every kind of authentication mode was all attempted and trust degree value during lower than default release threshold value, be regarded as illegally unblanking and report to the police, thereby reaching effective anti-theft effect.
