Referring to Fig. 4, the user credit method of adjustment S400 based on block chain includes:
S41, receive ordinary node send original block data, original block data include user account information and
User is in the behavior image in unmanned shop, and the account information of user is configured with the credit accounts of credit score；
S42, according to original block data, intelligent contract is executed, to adjust the credit score of the credit accounts of user；
Each user before entering unmanned shops for goods, can the register account number in cell phone application in advance, unmanned quotient
Office system is that the user distributes account information, and each account information is all corresponding with a credit accounts, each credit accounts
All there is credit score corresponding with the user.After user succeeds in registration for the first time, the initial credit score of each user is all identical,
For example, the corresponding initial credit score of the account information of user A, user B, user C is all 100 points.
Behavior image is the corresponding image of user's any consumer behavior in unmanned shop.User takes the photograph at unmanned shop
As head face tracking user, and the image for whole periods that shoot user in unmanned shop, behavior image is generated with this.For example,
Behavior, the behavior of hand-held commodity to clearing area clearing, mutual side that user behavior includes the behavior of picking commodities for users, destroys commodity
The behavior etc. of other user's shopping.
Manager formulates the consumer behavior code requirement in unmanned shop, for evaluating consumption row of the user in unmanned shop
For normalization.Consumer behavior includes legal consumer behavior and illegal consumer behavior, and legal consumer behavior is user in unmanned quotient
The behavior that consumer behavior in shop is conformed to the standard, illegal consumer behavior are that consumer behavior of the user in unmanned shop has not been able to close
The behavior of specification.
In order to reach can consumer behavior of the full automatic monitoring user in unmanned shop, manager is in background system system
A series of fixed consumer behavior characteristic points, the normalization of the consumer behavior for judging each user.For example, manager is rear
Platform system has prestored behavioural characteristic point relevant to the limbs behavior that do not conform to the standard, for example, user fights in unmanned shop,
When the limbs behavior of fighting of the user is matched with the behavioural characteristic point prestored, background system automatically determines the user in unmanned shop
Consumer behavior be illegal consumer behavior.For another example user destroys the label of commodity, the destruction of the user and the row prestored
When being characterized matching, it is illegal consumer behavior that background system, which automatically determines consumer behavior of the user in unmanned shop,.
Generally, there is also various ways to determine consumer behavior of the user in unmanned shop, it is not limited on
State what embodiment was illustrated.
After the behavior image in unmanned shop, being formed includes using by account information that ordinary node collects user and user
The original block data of the account information at family and user in the behavior image in unmanned shop.Then, ordinary node is by region of initiation
The credit adjustment request is sent to agent node according to credit adjustment request is packaged in by block number.Credit adjustment request triggering agency
Node executes intelligent contract.For example, the account information of user and behavior image are packaged in credit adjustment request by ordinary node, and
The credit adjustment request is sent to agent node.Agent node parses credit adjustment mark, root from the credit adjustment request
Mark acquisition is adjusted for executing the intelligent contract of credit adjustment type according to the credit.Then, agent node executes intelligence conjunction
About, to adjust the credit scores of the credit accounts of user.Wherein, which is that user's letter is voluntarily adjusted according to business demand
Code collection.
For example: agent node executes the intelligent contract of block chain, to adjust the credit score of the credit accounts of user
During, firstly, the treaty content that agent node executes the intelligent contract of block chain judges behavior figure according to treaty content
Whether the characteristics of image of picture matches pre-set image feature；If matching, when pre-set image feature is the figure for rewarding legal consumer behavior
When as feature, increase the credit score of the credit accounts of user, when pre-set image feature is the image for punishing illegal consumer behavior
When feature, the credit score of the credit accounts of user is reduced.If not matching, therefore abandoning original block data can reduce
Block chain stores the pressure of unnecessary data.
As previously mentioned, manager can train a sample database according to legal consumer behavior or illegal consumer behavior in advance,
The sample database is integrated with pre-set image feature corresponding with legal consumer behavior or illegal consumer behavior.Manager is pre- by sample database
It is stored in agent node, whenever triggering the intelligent contract of agent node execution credit adjustment, agent node is just according to image analysis
Algorithm, the behavior image mapping picture analysis to user, and characteristics of image is extracted in subordinate act image, by the image of behavior image
Feature is matched with the pre-set image feature in sample database.
S43, the new block data comprising credit score after adjustment are generated；
S44, new block data are sent to common recognition node, so that common recognition node common recognition verifying new block data, wherein common recognition
The common recognition algorithm of verifying uses share authorisation verification algorithm.
After agent node has executed intelligent contract, agent node just generates the new district block number comprising credit score after adjustment
According to.In some embodiments, when new block data are sent to common recognition node by agent node, agent node uses own private key pair
New block data make signature operation, obtain block signature, wherein public key broadcasts corresponding with private key are to block catenary system.Secondly,
Agent node sends new block data by block signature with the encapsulation of new block data and to common recognition node again, and common recognition node verification is new
When block data, common recognition node is signed using the legal public key verifications block of agent node, if block signature is legal, is just thought new
Block data is sent by lawful agencies node.If block signature is illegal, just think that new block data are sent out by illegal agent node
It send, therefore, can be improved the safety of block data using such mode.
When node verification new block data of knowing together are that lawful agencies node is sent, each common recognition node is proved using share
Algorithm (Proof of Stake, POS) appoints equity to prove that algorithm (Delegated Proof of Stake, DPOS) is right
New block data are verified.After being verified the new block data, the other block informations of node completion of knowing together, other blocks
