Efficiency, second participates in node, is also used to after receiving transaction and preparing after broadcast message, determines the enterprise of incomplete company information
Industry information type, and believed by the complete enterprise corresponding with company information type that non-block chain network obtains the first enterprise customer
Cease (step 21).
In one embodiment of the invention, as shown in figure 4, on the basis of as shown in Figure 2, in order to further increase pair
First participates in the authentication efficiency of node, and first participates in node, is also used to send in block chain network by the first enterprise
Before transaction after the first private key signature of user prepares broadcast message, node is participated in second by non-block chain network and is sent
The complete company information of first enterprise customer, and record the company information type of the second enterprise customer mark and complete company information
Corresponding relationship, with send trade prepare broadcast message when, according to corresponding relationship generate the first enterprise customer incomplete enterprise
Industry information (step 11).
When being executed for the intimacy protection system of the more detailed block chain real name communication for illustrating the embodiment of the present invention
Details concentrates on area so that the secret protection process that those skilled in the art communicates real name of the present invention is clearer below
The method for secret protection side of block chain real name communication is described.
Fig. 5 is the flow chart of the method for secret protection of block chain real name communication according to an embodiment of the invention, such as Fig. 5
It is shown, this method comprises:
Step 101, the first participation node sends the first private key signature by the first enterprise customer in block chain network
Rear transaction prepares broadcast message, wherein it includes: the of the first enterprise customer in block chain network that transaction, which prepares broadcast message,
Second enterprise customer mark of second enterprise customer of one enterprise customer mark and pending communication transaction in block chain network
Know, the incomplete company information of the first enterprise customer and the finance report by the private key signature of audit server in block chain network
Table and the first identifying code of the first enterprise customer.
Wherein, the authentication that the first public key and the first private key participate in node for first, the first private key are participated in by first
Node is held oneself, and the first public key is sent to block chain network in the form broadcasted, so that the phase communicated with the first participation node
Corresponding relationship of the artis based on the first public key and the first private key participates in node to first and carries out authentication.
In addition, above-mentioned first enterprise customer is corresponding with the first participation node, the corresponding enterprise of the first participation node can be,
First enterprise customer mark can be node ID etc. for indicating node identification of the first participation node in block chain network,
Likewise, the second enterprise customer mark is for indicating node identification of the second participation node in block chain network, it can be section
Point ID etc., the both sides that can orient transaction based on the first enterprise customer mark and the second enterprise customer mark participate in node.First

Capital, registered address, Business Registration Number (number of registration 569876654324567), establishment time etc., the first enterprise of mark used
The information of the true identity at family, the incomplete information of the first enterprise customer can be the information of hidden parts company information, for example,
Certain key messages: * * star company, the number of paying taxes 1234***90 are replaced using asterisk.
The first identifying code of first enterprise customer is the complete company information meter according to one-way function to the first enterprise customer
It obtains, wherein the first identifying code and the complete company information of the first enterprise customer uniquely correspond to, and add via one-way function
The first identifying code after close, cannot inversely export the complete company information of the first enterprise customer, even if there is artis acquisition as a result,
To the first identifying code, the complete company information of the first enterprise customer can not be also exported, to ensure that the first enterprise customer's is hidden
Private avoids the rival of the first enterprise customer from finding its trading activity etc., in addition, in an embodiment of the present invention, in order into
One step avoids identifying code from being cracked, and identifying code, which can be, to be calculated by multinomial enterprise's complete information, for example, there is one-way function
Complete Business Name, legal representative's (name+identification card number), registered capital, registered address, enterprise to the first enterprise customer
Multinomial enterprise's complete informations such as industry number of registration (number of registration 569876654324567), establishment time are calculated first and test
Demonstrate,prove code.
Specifically, the first participation node is sent after the first private key signature of the first enterprise customer in block chain network
Transaction prepare broadcast message after, first, can based on the second enterprise customer in the broadcast message identify further orient
The Correspondent Node of transaction；Second, it can be identified based on the first enterprise customer and show its identity in block chain network, in order to
The Correspondent Node of transaction further carries out authentication to first enterprise customer；Third, based on the transmission of the first identifying code, with
Node progress real-name authentication can be participated in first convenient for the Correspondent Node of transaction, convenient for guaranteeing the legitimacy of transaction；
4th, include incomplete company information in broadcast message, gets the incomplete company information even if the node in block chain
The true identity that can not know the first enterprise customer protects the privacy of the first enterprise customer.Wherein, in order to ensure the first enterprise
The personal secrets of user avoid illegal node from deriving complete company information, incomplete enterprise's letter by incomplete company information
Most information that is hiding or masking complete company information or important message part in breath, for example, concealing identity
Latter four etc. for demonstrate,proving number.；5th, in order to avoid not being that other illegal enterprises first enterprise customer that disguises oneself as trades, hand over
Easily prepare in broadcast message to further include by the financial statement of the private key signature of audit server in block chain network as a result, one
Aspect, only enterprise customer itself possess the financial statement, thus, which can be used to confirm that the first enterprise customer's
On the other hand identity can guarantee the authenticity of financial statement via the financial statement after audit server private key signature, avoid
Illegal node forges financial statement, wherein in order to guarantee that the real reliability of company information, financial statement need actual life
In the office with financial audit qualification proof of affixing one's seal, or by there is financial audit qualification in block chain
The financial statement that the private key signature of the corresponding audit server of office is crossed.
Step 102, the second participation node receives transaction and prepares after broadcasting the message, and uses using the first enterprise obtained in advance
First public key at family carries out signature verification to the first private key, if being verified, by enterprise of the own node in block chain network
Compared with industry user identifier is identified with the second enterprise customer, if knowing, the two is identical, is looked into according to the node identification of audit server
Local block chain account book is ask, public key corresponding with the node identification of audit server is obtained, the finance are reported using public key
Table carries out signature verification.
As analyzing above, the first public key and the first private key public key pair each other, thus, the second participation node receives friendship
After easily preparing broadcast message, signature verification is carried out to the first private key using the first public key of the first enterprise customer obtained in advance,
To ensure that transaction broadcast message participates in what node was sent for first, rather than what other nodes illegally pretended were sent etc., into
And if the verification passes, then whether verifying second is participated in node is the current Correspondent Node that communicates of first participation node,
With ensure both parties identity it is correct.
Specifically, second enterprise customer mark and second enterprise use of the node by own node in block chain network are participated in
Family mark compares, and to ensure that the first participation node is the node communicated with, if being verified, shows current first ginseng
It is that second communicated with participates in node with node, after transaction node both sides confirmation, not in order to further ensure financial statement
It is to forge, avoids illegal transaction, further the authenticity of financial statement is verified.
Specifically, inquiring local block chain account book, acquisition and audit server according to the node identification of audit server
Corresponding public key, the public key and private key are a pair of secret keys pair, can be used for verifying the identity of audit server, using public key to wealth
Business report carries out signature verification, to ensure the authenticity of financial statement.
Step 103, if the second participation node passes through verification of financial statement using public key, basis first passes through non-block in advance
Whether the incomplete company information of complete company information detection for the first enterprise customer that chain network obtains is all correct, if knowing non-
Complete company information is all correct, then is counted according to complete company information of the preset one-way function to the first enterprise customer
It calculates, obtains the second identifying code of the first enterprise customer, wherein the company information class of complete company information and incomplete company information
Type is identical.
Step 104, the second participation node compares the first identifying code and the second identifying code, if both know it is identical, to the
The authentication of one enterprise customer passes through, and participating in node feeding back to first includes the transaction preparation sound that the second enterprise customer identifies
It answers.
Specifically, if the second participation node passes through verification of financial statement using public key, i.e., public key and financial statement are signed
Private key matching, then show that financial statement is true and reliable, thus, second participate in node to first participate in node it is corresponding first enterprise
Whether industry user carries out real-name authentication, all correct according to the incomplete company information of complete company information detection, if knowing non-complete
Whole company information is all correct, then is further carried out according to complete company information of the preset one-way function to the first enterprise customer
It calculates, obtains the second identifying code of the first enterprise customer, compare the first identifying code and the second identifying code, as described above,
First identifying code and the second identifying code and the complete company information of enterprise customer are uniquely corresponding, thus, if the two is identical, table
The bright authentication to the first enterprise customer passes through, so that participating in node feeding back to first includes the friendship that the second enterprise customer identifies
It is easily ready to respond to, to allow the first participation node to trade with the second participation node.
In this example, it is not all of correctly if detecting incomplete company information according to complete company information, such as phase
With the information of position, there are inconsistent, it is determined that and incomplete information is incorrect, thus, determine the real-name authentication of the first participation node
Failure, refusal are communicated with the first participation node.Alternatively, the first identifying code and the second identifying code be not identical, it is determined that complete
Information is incorrect, thus, determine the real-name authentication failure of the first participation node, refusal is communicated with the first participation node.
It is emphasized that in this example, being detected first than more complete company information and whether incomplete company information
Unanimously carry out the preliminary real-name authentication of carry out for participating in node to first, after consistent, by comparing the first identifying code and the second verifying
Whether code identical to participate in node to first and carries out further real-name authentication, as a result, when complete company information detect with it is non-complete
When whole company information is inconsistent, it is confirmed that first participates in the failure of node real-name authentication, the first identifying code and the are not needed to compare again
Whether two identifying codes are consistent, improve real-name authentication efficiency.
In an embodiment of the present invention, in order to protect the personal secrets of the first participation node, the first enterprise customer's is complete
Company information does not store in the higher block chain network of transparency, and is stored in the relevant position of non-block chain network, than
Such as, it is stored in the corresponding equipment of the first participation node, second participates in node can be by way of communicating from first face-to-face
Participate in the complete company information that corresponding first enterprise customer is got in the corresponding equipment of node.
For the ease of the subsequent real-name authentication for participating in node to first, complete company information in the present embodiment with it is incomplete
Company information type is identical, for example, complete company information is that then incomplete company information is also corporate tax to corporate tax information
Information.
It should be noted that in practical applications, according to the difference of application scenarios, realize complete company information with it is incomplete
The identical mode of company information type is different, illustrates as follows:
As an example:
Second participation node determines the company information type of incomplete company information, for example, according to the enterprise of incomplete information
Industry information type carries out keyword match, determines the company information type of incomplete company information, in turn, passes through non-block link network
Network obtains complete company information corresponding with company information type.
As another example:
First participation node actively sends the complete company information received with the second participation node to the second participation node
The corresponding incomplete information of type is sent in block chain network in the first participation node by the first enterprise in this example
Before transaction after the first private key signature of user prepares broadcast message, first participates in node by non-block chain network to second
The complete company information that node sends the first enterprise customer is participated in, and records the second enterprise customer mark and complete company information
The corresponding relationship of company information type, to generate the first enterprise according to corresponding relationship and use when sending transaction preparation broadcast message
The incomplete company information at family.Complete enterprise corresponding with the second enterprise customer mark is got according to the corresponding relationship to believe
The company information type of breath generates the consistent incomplete company information of company information type with the complete company information in turn
Type.
As another example:
The friendship after the first private key signature of the first enterprise customer is sent in block chain network in the first participation node
Before easily preparing broadcast message, first, which participates in node, sends transaction verification broadcast message by block chain network, wherein transaction is tested
Card broadcast message include: the first enterprise customer the first public key and the first enterprise customer company information type so that other
The enterprise customer for carrying out communication interaction with the first enterprise customer passes through non-block according to the company information type of the first enterprise customer
Chain network obtains the complete company information of the first enterprise customer, thus, first participates in its enterprise to be sent of node active broadcast
The information type of information is sent with guaranteeing that the second participation node communicated with the first participation node is got with the first enterprise customer
Incomplete company information the corresponding complete company information of company information type.
In order to enable those skilled in the art more understands that the privacy of the block chain real name communication of the embodiment of the present invention is protected
Maintaining method is illustrated below with reference to specifically application scenarios:
In this example, as shown in fig. 6, it is enterprise customer B that the first participation node, which is corresponding first enterprise customer, second
Participating in the corresponding enterprise customer of node is enterprise customer A, and company information includes Business Name, legal representative, registered capital, note
Time, financial statement, the number of paying taxes, are set up at Business Registration Number in volume address, when enterprise customer A and enterprise customer B will trade
It waits, other real-life channels that enterprise customer A passes through non-block chain first obtain the complete company name of enterprise customer B
