The embodiment of the invention provides a kind of credit date storage methods based on block chain, are this hair referring to Fig. 2, Fig. 2
A kind of flow diagram of bright credit date storage method first embodiment based on block chain.
In the present embodiment, the credit date storage method based on block chain the following steps are included:
Step S10: the first choosing to any backlog in credit applications operation flow list of detecting user's triggering
Middle instruction.
Specifically, the executing subject in the present embodiment is specially the user terminal that can be interacted with user.
It should be understood that in practical applications, above-mentioned described user terminal specifically can be and be equipped with credit application
The intelligent terminal that can arbitrarily access internet of program (Application, App), such as smart phone, plate electricity
Brain, personal computer etc., will not enumerate herein, and any restrictions are not also done to this.
However, it should be understood that handling credit applications due in actual job and needing to be related to multiple links, therefore
It in the present embodiment, include at least one backlog in the credit applications operation flow list.
It should be noted that in the concrete realization, the backlog shown in credit applications operation flow list, specifically
Can be " the increase letter certification " item for needing to carry out in credit applications business, " improving contact information " item, " improve it is personal/
Company information " item, " the loan product title of application " item, " amount of the loan " item, " length of maturity " item etc., herein not
It enumerates again, any restrictions is not also done to this.
In addition, the safety in order to guarantee credit operation data under user name, processing backlog is produced in the present embodiment
Raw data are that the storage mode based on block chain stores, and are respectively corresponded not particular by above-mentioned each backlog is arranged
Same memory block, and sequencing of each memory block according to each backlog in credit applications business is set, it presses
Sequence is distributed on the fundamental chain of block chain.It is then each i.e. using each backlog as an individual processing links
A backlog distributes one dedicated for the memory block for the data for storing processing links generation, and such user is carrying out
When credit applications business, so that it may first a backlog for having been prepared for good material is selected to start to process, rather than it is required
It is handled according to the sequence of backlog in credit applications operation flow.
Further, since each memory block is the sequencing according to the backlog of storage in credit applications business,
It is distributed on the fundamental chain of block chain, therefore credit agency is in the number for obtaining user's typing from the credit service device based on block chain
According to when, all data is that the sequencing according to backlog in credit applications business obtains, therefore will not give credit
The business personnel of mechanism brings puzzlement.
That is, for the user that provides a loan, the sequence of updates is not limited by by this storage mode
The fixation process of credit applications business, and business personnel, when auditing credit applications, the data got are according to credit Shen again
Please operation flow, therefore can be convenient the use of both parties.
In addition, it is noted that in the present embodiment, user terminal detect user's triggering to credit applications Business Stream
The first of any backlog chooses the mode of instruction in Cheng Liebiao, specifically can be and is realized using Visual Tracking, tool
The implementation of body approximately as:
(1) eyes of user is detected by imaging sensor and watches position attentively in the credit applications operation flow list,
Obtain the iris image of eyes of user.
It should be understood that in practical applications, for detecting eyes of user in the credit applications operation flow list
In watch position attentively, and obtain the imaging sensor of the iris image of eyes of user, specifically can be that be set to the user whole
Imaging sensor in end, such as the camera of user terminal are also possible to communicate to connect by way of wirelessly or non-wirelessly
External imaging sensor, such as external camera, image capture device etc., will not enumerate herein, also not appoint to this
What is limited.
(2) model is extracted according to the iris feature constructed in advance, extracts the iris feature point in the iris image.
It should be understood that in order to guarantee going on smoothly for this method, above-mentioned described iris feature extracts model and needs
Building, specific building mode can substantially be divided into three steps in advance:
Firstly, constructing training pattern according to the sample data that sample data is concentrated.
Specifically, sample data described herein can be by testing simulating actual conditions, and it is each to fabricate having of
The iris image etc. of kind feature.
It is also possible that the magnanimity truthful data stored in various big data platforms, such as special iris image, or tool
There is the facial image etc. of iris information.
Then, the convolution kernel in the training pattern having a size of 5 × 5 is split as four having a size of 3 × 3 convolution kernel.
Specific fractionation mode can be as shown in Figure 3.
Specifically, alphabetical A in Fig. 3 indicates to be the convolution kernel in training pattern having a size of 5 × 5, alphabetical A1, A2,
A3 and A4 be split after four having a size of 3 × 3 convolution kernel.
Finally, being based on convolutional neural networks algorithm, in the training pattern each 3 × 3 convolution kernel is trained, is obtained
The iris feature extracts model, i.e., is trained respectively to convolution kernel A1, A2, A3 and A4, according to the instruction of above-mentioned 4 convolution kernels
The set for practicing result extracts model to construct final iris feature.
In the present embodiment, when constructing iris feature extraction model, by being trained based on the training pattern after fractionation,
Increase the network depth of training pattern so that the iris feature that is trained according to the training pattern after fractionation extract model into
When row extracts the operation of iris feature point, the iris feature point for being more in line with requirement can be extracted.
(3) at least five iris feature point is randomly selected from each iris feature point, according to ellipse fitting method, is fitted one
It is oval.
It should be understood that at least needing 5 points because of elliptical building, therefore it is arranged in this case from the crowd extracted
In more iris feature points, at least five is randomly selected, thereby may be ensured that according to ellipse fitting method, is fitted an ellipse.
In addition, the basic ideas of above-mentioned described ellipse fitting method, specifically: for giving one group of sample in plane
Point finds an ellipse, makes it as close to these sample points.That is, by one group of data in image with ellipse side
Journey is fitted for model, and a certain elliptic equation is made to meet these data as far as possible, and finds out the parameters of the elliptic equation, most
The best elliptical center determined afterwards is following described center coordinate of eye pupil.
(4) elliptic geometry formula is utilized, the ellipse is calculated, the elliptical elliptical center coordinate is obtained, and
Using the elliptical center coordinate as the center coordinate of eye pupil of the eyes of user.
Specifically, elliptic geometry formula used in this case is as follows:
Wherein, (h, k) is the elliptical elliptical center coordinate of building, and a is the elliptical major semiaxis, and b is this elliptical section
Semiaxis, (x, y) are the coordinate of any iris feature point at least five iris feature point randomly selected.
In calculating process, above-mentioned formula is brought by the coordinate at least five iris feature point that will be randomly selected, is obtained
5 equations.Then elliptical center coordinate (the namely centre coordinate of pupil), elliptical is calculated according to this 5 equations
Major semiaxis and semi-minor axis.
(5) situation of change for monitoring the center coordinate of eye pupil, that is, monitor the center coordinate of eye pupil within a preset time
Whether change, if the center coordinate of eye pupil does not change within a preset time, triggers the center coordinate of eye pupil
The first of corresponding backlog chooses instruction.
For example, the center coordinate of eye pupil of the user determined according to aforesaid way rests on one in a predetermined time segment
In a selectable backlog, such as 800 milliseconds are stopped, at this time it is considered that user is selected, credit APP meeting
It is automatic to execute the corresponding event of the corresponding backlog of center coordinate of eye pupil, instruction is chosen to make first.
In addition, in order to guarantee the treatment process for accelerating to determine center coordinate of eye pupil, it in practical applications, can be according to pre-
The iris feature first constructed extracts model, before extracting the iris feature in the iris image, carries out to the iris image
Normalized, i.e., a series of processing for carrying out marks to iris image convert, and iris image is made to become fixation, standard
Normalized image thereby may be ensured that and extract model according to the iris feature constructed in advance, from the iris figure after normalized
The iris feature point useful to calculating center coordinate of eye pupil is extracted as in.
It should be noted that being given above only a kind of user terminal detecting user to credit applications operation flow list
In any backlog the first specific implementation for choosing instruction, the technical solution of the present inventor is not constituted any
It limits, in the concrete realization, those skilled in the art can according to need setting, herein with no restrictions.
In addition, those skilled in the art can be by searching for existing normalized about normalized processing mode
The related data of method realizes that details are not described herein again.
Step S20: instruction is chosen according to described first, the backlog described in user interface presentation is corresponding to be processed
Item list.
Specifically, due to needed in a backlog user supplement data often more than one, this
It include at least one task items in the backlog list in embodiment.And in order to as far as possible will be to be processed
Task items under item show user, tabular form would generally be used in the concrete realization, by all requiring supplementation with for tasks
Item, which is all shown, to be come, for example the backlog that user chooses is " increasing letter certification " item, then in the backlog list just
It can exist for the supplemental content that user is the individual or company information that assure, such as enterprise name, address, the legal person for disclosing channel
Information, the industrial and commercial registration number of enterprise, credit code etc., will not enumerate herein, any restrictions are not also done to this.
In addition, in order to further ensure the safety of credit operation data under user name, and convenient for memory space

(missing the time, which will be invalid, or unnecessary economic loss may be brought to user) handles the loan industry
Duration, the corresponding Review Cycle of the loan transaction (such as from application lending to the end) duration of business needs.
For example, the backlog one for meeting the backlog recommendation rules got share 3 (respectively to
Handle item A, backlog B and backlog C), need user intervene supplemental information absolutely in limited time between be respectively May 1
Day, May 5 and May 10；User is respectively 3 hours time for needing to spend in intervention treatment process, and 5 hours and 1 small
When；The audit duration that this 3 backlogs need to spend after information completion is respectively 7 days, 2 days and 5 days.
If in preset weight distribution standard, the weight between prescribing a time limit absolutely is 45%, handling duration 25% audits duration
It is 30%.
It is assumed hereinafter that the full marks of each be 15 points, according to the urgency level of each single item, for example, absolutely in limited time between closer to current
The score on date is higher, and shorter score is higher the time required to processing, and the longer score of Review Cycle is higher, then backlog
A absolutely in limited time between score value be 15 points, handling duration score value be 10 points, audit duration score value be 15 points；The exhausted limit of backlog B
Time score value is 10 points, and handling duration score value is 5 points, and audit duration score value is 5 points；Backlog C absolutely in limited time between score value
It is 5 points, handling duration score value is 15 points, and audit duration score value is 10 points.
By calculating, the weighted value of this three loan transaction backlogs is respectively as follows:
Backlog A=15*45%+10*25%+15*30%=6.75+2.5+4.5=13.75；
Backlog B=10*45%+5*25%+5*30%=4.5+1.25+1.5=7.25；
Backlog C=5*45%+15*25%+10*30%=2.25+3.75+3=9.
