In a second embodiment, the step S10, comprising:
Step S101: the veritification precision under business scenario and targets threshold section are obtained.
Step S102: chosen in the targets threshold section meet it is described veritify precision by score threshold, and build
Vertical business scenario and the default mapping relations for passing through score threshold.
It is understood that the precision of veritifying refers to the percent of pass veritified and False Rate, each business scenario is to veritification
Required precision is different, such as under the business scenario of user's login, it is desirable that the percent of pass that user veritifies is higher, the business that user saves from damage
Under scene, it is desirable that the False Rate that user veritifies is lower, therefore, by the veritification precision different to different business scene setting.It is described
Targets threshold section refers to wanting comprising target by one of score threshold substantially section, such as the business scenario that user logs in
The targets threshold section asked is about 40-60 points, and the targets threshold section for the business scenario requirement that user saves from damage is about 65-90
Between, subsequent will determine from the targets threshold section final passes through score threshold.
Step S103: obtaining current business scene, and searches and the current business field in the default mapping relations
The corresponding target of scape passes through score threshold.
It, can be according to working as it should be noted that after establishing business scenario with by the default mapping relations of score threshold
Preceding business scenario searches corresponding target in the default mapping relations and passes through score threshold.
Further, the veritification precision includes target percent of pass and target False Rate;
The step S102, comprising:
The sample data under business scenario is obtained, the sample data includes sample facial image, the positive negativity of sample and sample
This similarity score.
Successively chosen in order in the targets threshold section it is undetermined by score threshold, according to it is described it is undetermined by point
Number threshold values, the positive negativity of the sample and Sample Similarity scoring calculate the current percent of pass of the sample facial image and work as
Preceding False Rate.
It is not less than the target not higher than the target percent of pass and/or the current False Rate in the current percent of pass
When False Rate, selection is next undetermined by score threshold, and returns described according to described undetermined by score threshold, the sample
This positive negativity and Sample Similarity scoring calculate the current percent of pass of the sample facial image and the step of current False Rate
Suddenly.
It is higher than the target percent of pass in the current percent of pass, and the current False Rate is lower than the target False Rate
When, undetermined score threshold is passed through as the precision of veritifying is met by score threshold for described.
It should be noted that being higher than the target percent of pass in the current percent of pass, and the current False Rate is lower than
When the target False Rate, illustrate it is described it is undetermined the veritification precision is met by score threshold, undetermined pass through score for described
Threshold value passes through score threshold as the precision of veritifying is met under business scenario.
In the concrete realization, it is illustrated by taking the business scenario that user saves from damage as an example, the business scenario saved from damage due to user
To veritifying, required precision is higher, and it is that target percent of pass is not less than 70% that initial setting, which veritifies precision, and target False Rate is not higher than
10% and targets threshold section be 65-90 point, in the section, in order by each score value successively as threshold value undetermined point
Value, under different threshold scores undetermined, calculates separately current percent of pass and current False Rate;Current percent of pass is missed with current
The threshold scores undetermined for sentencing rate satisfaction veritification precision pass through score threshold as target.It is allocated as example, working as 60 as threshold value undetermined point
When value, percent of pass 80%, False Rate 20%;When 72 are allocated as threshold scores undetermined, percent of pass 75%, False Rate is
8%;When 85 are allocated as threshold scores undetermined, percent of pass 65%, False Rate 8%.It therefore meets veritifying the undetermined of precision
It is 72 points by score threshold, so 72 are allocated as to pass through score threshold for target.
Further, it is described successively chosen in order in the targets threshold section it is undetermined by score threshold, according to
Undetermined scored by score threshold, the positive negativity of the sample and the Sample Similarity calculates the sample facial image
Current percent of pass and current False Rate, comprising:
It is successively chosen in order in the targets threshold section and undetermined passes through score threshold;
According to Sample Similarity scoring and the veritification undetermined by score threshold judgement sample as a result, according to institute
It states and veritifies the current percent of pass that result calculates the sample facial image;
According to the positive negativity of the sample and the current False Rate veritified result and calculate the sample facial image.
In the concrete realization, it is similar that multiple positive samples under each business scenario, multiple negative samples and corresponding sample are obtained
Degree scoring, for each business scenario, selection one is undetermined in the targets threshold section of the business scenario passes through score threshold
Value, when Sample Similarity scoring lower than it is described it is undetermined pass through score threshold when, it is believed that Sample Similarity scores corresponding sample
Veritify result be do not pass through, otherwise it is assumed that veritify result be pass through, according to it is described veritification result be by sample number divided by total
Sample number calculates current percent of pass;It according to the positive negativity of sample and veritifies result simultaneously and calculates current False Rate, when sample is positive sample
This, and veritify result be by when, be denoted as correct judgment, when sample be positive sample, and veritify result be it is obstructed out-of-date, be denoted as and sentence
Dislocation miss, when sample be negative sample, and veritify result be by when, be denoted as misjudgment, when sample be negative sample, and veritify tie
Fruit be it is obstructed out-of-date, correct judgment is denoted as, to calculate current False Rate according to judicious sample number and total number of samples.
In a second embodiment, veritification precision and the targets threshold section under business scenario are obtained;In the target threshold
It chooses in value section and meets the precision of veritifying and pass through score threshold.Based on the sample data of many experiments room, acquisition most can
