Description
Technical field
The present invention relates to electronic certificate field, in particular to a kind of electronic certificate management method based on block chain and it is
System.
Background technique
Electronic certificate is also digital certificates, and digital certificates can be considered " online identity card ", in online as verification holder
Identity is used.Electronic certificate can ensure that integrality and confidentiality of the data in electronics transmit process, and ensure have it is powered-down
After the completion of son transaction, confirmation both sides once traded.Traditional electronic certificate includes two dimensional code, RFID, and management generally requires
Third party is relied on to complete.Moreover, electronic certificate is signed and issued highly dependent upon traditional center trust authority, as bank, futures are handed over
The centralizations mechanisms such as easy institute, the third-party institution, only can just complete signing and issuing for electronic certificate by these center trust authorities.
There are still the risks of leakage of personal information for electronic certificate.Block chain is a similar open network account book.It originate from than
Special coin is the Floor layer Technology of bit coin, and all information of transaction record can be packaged into one " block " and be stored, with
The expansion of information interchange, block is connected with each other one by one, is formed block chain.It is one by the digital cash of representative of bit coin
The point-to-point electronic cash system of kind, transaction can all broadcast participant all in network every time, and by multiple
It is just recorded in account book after confirmation, this account book is exactly " block chain ".Each participant can have an account book of oneself, in this way when
When deceptive information occurs, so that it may be abolished by mutually verifying, to guarantee network security.Each node in block chain
It is equality, there is no the management organization of centralization, running does not need anyone intervention, can independently carry out self testing
Card.In addition, the network of block chain is opened to the whole world, anyone can carry out data query by open port, thus whole
A system altitude is transparent, in short, block chain is a believable database, it is one reliable " account book ".
Generally speaking, block chain, Block Chain technology are that occur in recent years in the field financial technology (FinTech)
A kind of emerging technology, unique decentralization, information can not distort, multinode collective maintainability, publicity, secret protection etc.
Attribute can record based in incredible internet and provide believable trading information data.Block chain mainly includes P2P
Network, cryptography, common recognition mechanism, intelligence and about four component parts guarantee that its is exclusive by the technology integration in four fields
Characteristic, block chain technology are currently the only just to can be used for recording and proving that trade identity and Corporate Finance are quasi- without third party
The tool of true property, is able to satisfy the requirement to audit validity, accuracy and timeliness.However, the current electricity based on block chain
The management method of sub- voucher lacks effective user credit grade appraisement system.
Therefore, it is necessary to one kind, and center, anti-tamper, highly-safe, credit appraisal system to be gone to improve electronic certificate management method
And system.
In view of the above problems of the prior art, the application uses following technical scheme.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of electronic certificate management method based on block chain.User mentions
Electronic certificate is handed over to generate request, certification node authenticates user's request, and electricity is added in the user after user is by certification
Sub- voucher block chain node, and virtual electronic voucher is generated for user.User completes electronic reciprocal mistake by virtual electronic voucher
Journey, and by electronic reciprocal process record and other nodes for being synchronized to electronic certificate block chain.Credit appraisal block chain link is set
Point, the credit grade of monitoring management user and user's interactive object are deposited in electronic certificate interactive process if monitoring user
In the first unlawful practice, then the electronic certificate interactive operation of user is limited, if monitoring user's interactive object in electronic certificate
There are the second unlawful practices in interactive process, then limit the electronic certificate interactive operation of user's interactive object, and break one's promise above-mentioned
Other nodes in the block chain are informed in behavior in a manner of non-disclosre user and user's interactive object real information.In addition, this
Application further includes the system for realizing the above method.
