Random number is registered to meet the registration cryptographic Hash of registration message to one, is authenticated based on cryptographic Hash, thus, on the one hand, draw
Within a block, the great deal of nodes in block chain network stores corresponding difficulty value, even if there is a section for the difficulty value storage entered
Point collapse, nor affects on the extraction of difficulty value, on the other hand, is authenticated based on registration cryptographic Hash is calculated, the calculating process
Time loss avoid the camouflage of malicious node, if malicious node, which is wanted to pretend to be, participates in node to register, also have to pass through this
The calculating of process, malicious node calculate with while, legal participation node has been completed registration, and related news have been write
Block chain is entered.I.e. by increasing the time of intermediate malicious node attack, a possibility that so as to avoid malicious attack.
Details when being executed for the more detailed block chain real-name authentication system for illustrating the embodiment of the present invention, so that this
The technical staff in field is clearer to block chain real-name authentication process of the invention, concentrates on block chain real-name authentication side below
Method side carries out the description of the details of participation process.
Fig. 4 is the flow chart of block chain real name identification method according to an embodiment of the invention, as shown in figure 4, the party
Method includes：
Step 101, node is originated to be arranged in original block for carrying out real name registration to the user in block chain network
Difficulty value.
Wherein, difficulty value can be subsequent to participation node progress legitimate verification for limiting for specific time span etc.
Difficulty standard, in embodiments of the present invention, it is desirable that based on the difficulty value complete to participate in node legitimacy certification, than
Such as, it when the difficulty value corresponds to duration A, then requires to complete in duration A to authenticate the legitimacy for participating in node, once certification
Duration is more than duration A, then is determined as authentification failure.
It is emphasized that in an embodiment of the present invention, the difficulty value that original node is arranged in original block can quilt
In the block chain account book for broadcasting and being synchronized to other nodes in block chain network, thus, even if original node failure etc.,
Difficulty value can also be got from other nodes, ensure that the stability of verification process.
Step 102, it participates in node and obtains the certification video that application user records for carrying out real name registration, wherein certification
Video includes：Living body user, the user certificate comprising user certificate image and user certificate information.
Wherein, above-mentioned user certificate includes comprising user certificate image and the identity card of user certificate information, passport, student
Card, medical insurance card etc..
Specifically, in order to realize to the real-name authentication for participating in node application user, user, which needs to have prerecorded one section, to be recognized
Video is demonstrate,proved, includes living body user (i.e. true application user, rather than the images such as humanoid vertical board) in the certification video, comprising using
The user certificate of family certificate image and user certificate information participates in node and obtains the certification video that application user records in turn,
In, it participates in node and obtains the mode of certification video be user's active upload, it is corresponding using node is participated in be also possible to user
Equipment such as smart phone record after, participate in node and actively extract from relevant device.
Step 103, the original block participated in the block chain account book of querying node local synchronization obtains difficulty value, Yi Jiwei
Apply for that user generates registration random number, and obtains corresponding to the real name registration information of application user progress Hash calculation and be less than
The registration cryptographic Hash of difficulty value, wherein real name registration information includes：Authenticate video, registration random number, apply user public key and
User basic information and local time stamp, and then the private key of application application user is to real name registration information and registration cryptographic Hash
Certification broadcast message is generated after being signed is sent to block chain network.
As described above, the difficulty value that block is written can be synchronized to other nodes in block chain network, thus,
Block chain account book can be synchronized by participating in node, thus, inquire local synchronization block chain account book can from being synchronized to original block,
Difficulty value is obtained from original block.
Further, the restriction based on the difficulty value is authenticated, in an embodiment of the present invention, in the limit of the difficulty value
It fixs, the generation of the cryptographic Hash based on random number is authenticated, and in an embodiment of the present invention, participating in node is application user Shen
Random number (for example, generation etc. that random number can be carried out based on the program set) please be register, in turn, to the reality of application user
Name registration information carries out Hash calculation and obtains registration cryptographic Hash that is corresponding and being less than difficulty value, wherein real name family registration letter
Breath includes the relevant information of mark application user's uniqueness, including certification video, registration random number, the public key and use for applying for user
Family essential information and local time stamp, wherein local time stamp illustrates the calculating time for being currently generated registration cryptographic Hash.
It should be understood that needing to generate under the restriction range of difficulty value less than difficulty value in above-mentioned implementation procedure
Random number is registered, other malicious nodes participation node that disguises oneself as is avoided and is firmly registered the generation of cryptographic Hash, this is because,
Other malicious nodes generate the time of registration cryptographic Hash after currently participating in node, thus, when malicious node expends a timing
Between generate registration cryptographic Hash after, the registration cryptographic Hash be greater than the difficulty value, be based on the principle, in order to preferably avoid malicious node
Attack, in some possible embodiments, difficulty value and register cryptographic Hash calculating process consumption time should more connect
Closely.
Further, it is generated after signing using the private key of application user to real name registration information and registration cryptographic Hash
Certification broadcast message is sent to block chain network, wherein applies the private key of user only by applying for that user holds.
Step 104, the receiving time that mine nodes records receive certification broadcast message is dug, is docked using the public key of application user
The certification broadcast message of receipts carries out signature verification, if being verified, calculates the time difference between local time stamp and receiving time,
Know that the time difference meets preset time range after if, verifies user certificate image and whether living body user matches, if
Know correct matching, then verify whether user certificate information matches with user basic information, if knowing correct matching, detects use
Whether family certificate information was registered, if detection be not registered, verify registration random number and registration cryptographic Hash whether
Match, if knowing correct matching, it is determined that apply for that the real-name authentication of user passes through, and certification success message is written in block simultaneously
It is broadcasted to block chain network.
As foregoing description, the private key of participating user and the public key of the participating user in real name registration message are a pair of each other
Password, thus, in an embodiment of the present invention, the public key of digging mine node application application user is to received by participating user's
The certification that the certification broadcast message of private key signature is signed, when the signature in the public key and certification broadcast message of application user
Apply for the private key of user to then showing that transmission certification broadcast message is to participate in node itself when corresponding to, so that completion saves participation
The verifying again of the legitimacy of point.
If it is appreciated that digging receiving time and the time difference of local time stamp that mine node receives certification broadcast message
Away from larger, it is likely that be that other illegality equipments have intercepted and captured the certification broadcast message for participating in node transmission, disguise oneself as and participate in node
To the certification broadcast message etc. dug mine node and have sent intercepting and capturing, so as to cause receiving time and the lead time of local time stamp compared with
Greatly, thus, in an embodiment of the present invention, by calculating the time difference between local time stamp and receiving time, to ginseng
It is authenticated with the legitimacy of node.
Specifically, dig mine and calculate time difference between local time stamp and the receiving time, if after know the time
Difference meets preset time range, then shows that certification broadcast message participates in node itself really and sends, thus, to application
User carries out real-name authentication.
In one embodiment of the invention, if knowing that the time difference is unsatisfactory for preset time model after digging mine node
It encloses, then to block chain network broadcast authentication failed message.
Further, real-name authentication is carried out to application user, whether verifying user certificate image matches with living body user, i.e.,
Whether living body user is authenticated using my user certificate, if it does, then verifying user certificate information and user are basic
Whether information matches, and is further ensured that living body user carries out real-name authentication using my relevant information to verify, for example, working as
User certificate information includes that certificate number and user certificate title can when user basic information includes user identifier and user's name
It is whether identical to verify certificate number and user identifier, and verifying user certificate title and user's name it is whether identical.
In the present embodiment, in order to avoid the repeated registration of user, the fairness of block chain network is influenced, in verifying user
After certificate information is matched with user basic information, whether also detection user certificate information was registered, for example, detection related service
It is consistent etc. with active user's certificate information that it whether is stored with user certificate information corresponding with chartered node in device, and compares
Such as, it detects other to dig in mine nodes during the certification that stores successfully broadcast the message, if be stored with and the section of successful registration
The corresponding user certificate information of point is consistent with active user's certificate information etc., is not registered if detecting, verify register with
Whether machine number matches with registration cryptographic Hash, i.e., this registers whether cryptographic Hash applies for the participation node that block chain network is added as before
It sends, if correct matching, shows that the participation node for sending current registration cryptographic Hash is not the illegal node of camouflage, from
And determine that the real-name authentication of application user passes through, and certification success message is written in block and is broadcasted to block chain network.
In one embodiment of the invention, mine node is dug knowing how institute's user's certificate information was registered, the area Ze Xiang
Block chain network broadcast authentication failed message.
Wherein, under different application scenarios, certification success message can be about fixed expression and authenticate successful character string,
It is also possible to specifically indicate to authenticate successful text information etc., this is not restricted.
Step 105, it digs mine node and judges that whether receiving other within a preset time digs the instruction block that mine nodes are sent
Active broadcast message is not received by active broadcast message if knowing, comes into force to block chain network broadcast block, and by block
It is written in block chain account book.
It is understandable to be, after participation node is successfully accessed block chain network, even if completing real-name authentication, it is also possible to
The user of the real-name authentication is illegal user etc., thus, in order to guarantee that the participation node is normally carried out accounting activities, rather than into
The illegal activities such as row money laundering, need to verify the accounting activities whether the participation node executes normal legal.
Specifically, the digging mine node in block chain network is by Transaction Information recorded in account book etc. and the participation nodes records
The Transaction Information similarly traded be compared, if it is inconsistent, the digging mine node determine participate in node error in entering accounts, sentence
The corresponding block for authenticating success message of the participation node that breaks is invalid, digs whether the judgement of mine node receives it within a preset time
He digs the broadcast message for indicating that block is invalid of mine node transmission, active broadcast message is not received by if knowing, to block
Chain network broadcasts the block and comes into force, and block is written in block chain account book.
Certainly, in practical implementation, possible other dig mine node and error in entering accounts occur to which erroneous judgement currently participates in section
Point error in entering accounts, and active broadcast message is had sent, thus, when participating in block chain network to further increase participation node
The accuracy of verifying know if digging mine node in one embodiment of the invention and receive active broadcast message, judge
Whether the number of diggings mine node for sending active broadcast message is more than preset threshold, the preset threshold and dig the total of mine node and
The authority of digging mine node in block chain network is related, and the sum for digging mine node is more, digs the lower (ratio of authority of mine node
Such as it is only common participation node), then corresponding preset threshold is lower.
If digging mine node knows that number is less than preset threshold, show that the most digging mine node is to accept the block
, alternatively, without authoritative digging mine node think the block be it is invalid, thus, at this time to block chain network broadcast block
It comes into force, and block is written in block chain account book, conversely, number is more than or equal to preset threshold if knowing, to block chain network
It is invalid to broadcast the block.
In conclusion the block chain real name identification method of the embodiment of the present invention, realizes the real name to block chain interior joint
