Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly, understand, 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, be not intended to limit the present invention.
Be illustrated in figure 1 the method for unlocking process flow diagram of a kind of multi-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 comprises further: timing studying history certification case, is the focus period by slot setup high for frequency of unblanking, whether within the focus period, arranges basic degree of belief coefficient value according to current time.
Specifically, all acts of authentication that history certification case history is all previous unblanks and authentication result, after multi-lock opening anti-theft device, all cases of unblanking are read from database, analyze and draw the time period that success ratio of unblanking is the highest, and be set as the certification 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 initial trust degree coefficient value for this reason.Trusted coefficient is different according to setting difference, per half an hour such as can be adopted to reset an initial trust degree coefficient value, if there was unlocking person carrying out acts of authentication at that time, then put off next period setting.
S104, often receive an acts of authentication authentication result after, adjust current degree of belief coefficient value according to authentication result.
Specifically, acts of authentication can be any one authentication mode in multi-lock, includes but not limited to: magnetic card certification, finger print identifying, cipher authentication or mobile phone certification.If acts of authentication success, then promote degree of belief coefficient; If acts of authentication failure, then reduce degree of belief coefficient.
As a kind of preferred version of this step, current degree of belief coefficient value can be adjusted in real time in conjunction with the degree-of-difficulty factor of each certification link, if i.e.: acts of authentication success, then promote degree of belief coefficient value according to the degree-of-difficulty factor of current authentication; If acts of authentication failure, then reduce degree of belief coefficient value according to degree-of-difficulty factor value average.
Wherein, promote degree of belief coefficient according to the degree-of-difficulty factor of current authentication to comprise further: promote according to the amplification amassed of amplification coefficient with the degree-of-difficulty factor value of current authentication; Reduce degree of belief coefficient according to the degree-of-difficulty factor value of current authentication to comprise further: the long-pending range of decrease deducting degree-of-difficulty factor value and range of decrease coefficient according to range of decrease number reduces.
As the another kind of preferred version of this step, when acts of authentication success, current degree of belief coefficient value can also be adjusted in real time in conjunction with the authentication sequence custom of unlocking person, that is: when the order of certification is consistent with history success identity case, promote degree of belief coefficient value according to successful frequency values; When inconsistent, then do not adjust degree of belief coefficient value.Wherein, promote degree of belief coefficient value according to successful frequency values to comprise further: carry out lifting degree of belief coefficient value according to the long-pending amplification of similar degree amplification coefficient and similar ratio value.
S106, calculating trusted angle value.
Specifically, whether legal trusted angle value be used to judge to unblank foundation.Calculate trusted angle value to comprise further; According to when the degree-of-difficulty factor of time authentication result, authentication mode and degree of belief coefficient calculations are when the trust degree weights of time acts of authentication, and the trust degree weights of accumulative each acts of authentication, obtain trusted angle value.
For example, can adopt the weights calculating each certification link, then adding up obtains trusted angle value, the following formulae discovery of concrete employing:
Wherein, m represents the quantity of the authentication mode of employing; N represents the numbering of often kind of authentication mode; AuthDifficult
nrepresent the degree-of-difficulty factor of n-th kind of authentication mode; Belief
nrepresent the degree of belief coefficient after carrying out n-th kind of authentication mode success; AuthState
nrepresent the certification whether success status of n-th kind of authentication mode, being 1 during success, is 0 time unsuccessful.
S108, judge current trusted angle value whether exceed default unblock threshold value or lower than preset alarm threshold value, if so, perform step S110, otherwise perform step S112.
Specifically, by judging that trusted angle value judges whether unlocking person is owner, if when trusted angle value is greater than default unblock threshold value (such as can be set as 1.0), then perform unlocking motion; If when trusted angle value is lower than alarm threshold value (such as can be set as 0.1) of presetting, then perform actuation of an alarm; Trusted angle value between preset alarm threshold value and default unblock threshold value between time, then need to proceed other authentication modes, until complete all authentication modes, or trusted angle value be greater than default unblock threshold value or lower than preset alarm threshold value.
S110, when trusted angle value exceedes default unblock threshold value, send unlocking signal to perform unblock; When trusted angle value is lower than the alarm threshold value preset, send alerting signal to perform warning.
S112, judge whether all authentication modes, if so, then performed step S114, otherwise return step S104.
S114, transmission alerting signal are to perform warning.
The method for unlocking of the multi-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 unlock or report to the police, thus reach safe and convenient anti-theft effect if need not open that all locks just can identify.
The process flow diagram of the examples of many successful of unblanking of a kind of multi-lock provided by the invention as shown in Figure 2, assuming that existence 4 authentication modules, the degree-of-difficulty factor of its authentication module is followed successively by 0.6,0.5,0.5 and 0.4 respectively, 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 set unblock threshold value preset is 1.0, and warning degree of belief threshold value is 0.1, and supposes that each acts of authentication is all successful, then the method comprises the following steps:
S202, initialization degree of belief coefficient value.
Being set as initial value by degree of belief coefficient value, by application scenarios above, is 0.6 in the present embodiment.
S204, reception acts of authentication.
S206, in real time lifting degree of belief coefficient value, calculate trusted angle value.
Because this authentication result is successful, then can be that parameter carries out calculating 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, then this amplification=0.8 (amplification coefficient) * 0.6 (degree-of-difficulty factor)=0.48, degree of belief coefficient value after renewal is 0.6 (trusted coefficient value)+0.48 (this amplification)=1.08, then the trusted angle 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, then this amplification=0.8 (amplification coefficient) * 0.5 (degree-of-difficulty factor)=0.4, degree of belief coefficient value after renewal is 1.08 (trusted coefficient value)+0.4 (amplification)=1.48, then the trusted angle value of this acts of authentication is 0.5 (degree-of-difficulty factor) * 1.48 (trusted coefficient value)=0.74, then accumulative trusted angle value is now 0.648 (the trusted angle value of module 1)+0.74 (the trusted angle value of module 2)=1.388>1.0 (default unblock threshold value).
So far, accumulative trusted angle value is greater than default unblock threshold value, then follow-uply do not need user to operate further authentication module 3 and authentication module 4.
S208, act of authentication to be analyzed, promote trusted coefficient value further, calculate trusted angle value.
Specifically, this step reads the certification case similar with this acts of authentication order 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), then promotes degree of belief coefficient value:
Amplification=similar ratio value of similar degree amplification coefficient *.
Wherein, similar degree amplification coefficient is 0.2, if user is successfully completed the certification of authentication module 1 and module 2, and to there is ratio similar with it in the certification history case stored in a database be 0.7, then 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.Then the trusted angle value of this certification is 1.62*0.5=0.81.Accumulative trusted angle value is 0.648+0.81=1.458>1.0 (default unblock threshold value).
So far, accumulative trusted angle value is greater than default unblock threshold value, then follow-uply do not need user to operate further authentication module 3 and authentication module 4.
S210, judge whether trusted angle value is greater than default unblock threshold value, if so, then perform step S212, otherwise return step S204.
S212, transmission unlocking signal are to perform unblock.
S214, preserve this verification process.
This step to be unblanked case by record at every turn, based on data be supplied to the analysis foundation of follow-up certification of unblanking.
The method that the embodiment of the present invention provides, by analyzing the acts of authentication of unlocking person, and in conjunction with the real-time accumulated trust degree of case that history is unblanked, need not open all locks just can identified identity and unlocking, thus reaches safe and convenient anti-theft effect.
The process flow diagram of the failure example of unblanking of a kind of multi-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 0.6,0.5,0.5 and 0.4 respectively, 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 set unblock threshold value preset is 1.0, and warning degree of belief threshold value is 0.1, and supposes to have in acts of authentication successfully also have failure, and the method comprises the following steps:
S302, initialization degree of belief coefficient value.
Being set as initial value by degree of belief coefficient value, by application scenarios above, is 0.6 in the present embodiment.
S304, reception acts of authentication.
S306, in real time adjustment degree of belief coefficient value, and calculate trusted angle value.
When the authentication is successful, promote degree of belief coefficient, when the authentication fails, 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, then this amplification=0.8 (amplification coefficient) * 0.6 (degree-of-difficulty factor)=0.48, degree of belief coefficient value after renewal is 0.6 (trusted coefficient value)+0.48 (amplification)=1.08, now, the trusted angle 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, then 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, then 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), then report to the police.
Lift an example again:
When user's selective authenticate module 1 authentification failure, according to authentification failure computation model, then 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 success, according to authentication success computation model, then 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 failure, according to authentification failure computation model, then 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 success, according to authentication success computation model, then the degree of belief coefficient value after upgrading is 1.05, and trusted angle value is 0.4*1.05=0.42.
Calculate accumulative trusted angle value=0.44+0.42=0.86, because all authentication modes were all tasted, but the accumulative trusted angle value of user does not reach unblock threshold value yet, be then considered as illegal acts of authentication, report to the police.
Step S308: judge that whether trusted angle value is lower than the alarm threshold value preset, and if so, then performs step S312, otherwise performs step S310.
Step S310: judged whether all authentication modes, if so, then performs step S312, otherwise returns step S304.
Specifically, after attempting all authentication modes, trusted angle value still lower than the unblock threshold value preset, is then considered as abnormal behavior of unblanking, reports to the police.
S312, transmission alerting signal are to perform warning.
Specifically, according to warning demand, can various alarm be carried out, as sound and light alarm, SMS alarm, take pictures.
S314, preserve this verification process.
The method that the embodiment of the present invention provides, by analyzing the real-time accumulated trusted angle value of acts of authentication of unlocking person, when trusted angle value lower than during the alarm threshold value preset or often kind of authentication mode all attempted and trusted angle value lower than the unblock threshold value preset time, be regarded as illegally unblanking and reporting to the police, thus reach effective anti-theft effect.
