Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The block chain based digital certificate processing method provided by the present application can be applied to the application environment shown in fig. 1, where fig. 1 is an application environment diagram of the block chain based digital certificate processing method in an embodiment. The application environment may include a first terminal 110, a server 120, and a second terminal 130, wherein the first terminal 110, the server 120, and the second terminal 130 may all be node devices of a first blockchain system. Specifically, the first terminal 110 may obtain a digital certificate to be processed, and obtain certificate operation information and certificate verification information corresponding to the digital certificate by executing a first intelligent contract deployed in the first blockchain, and the first terminal 110 further determines a certificate verification node used for verifying the digital certificate in the first blockchain system, for example, the server 120 may be used as the certificate verification node, and then sends the certificate verification information to the server 120. Then, the first terminal 110 obtains the credential authorization information of the credential authentication information from the server 120, and verifies the credential authorization information by using the second intelligent contract deployed in the first block chain system to obtain an authorization verification result of the credential authentication node, if the authorization verification result is a verification pass, the first terminal 110 processes the digital credential according to the credential operation information, and as an example of operation on the digital credential, the first terminal 110 may transfer the digital credential to the second terminal 130 according to the credential operation information.
The first terminal 110 and the second terminal 130 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 120 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, fig. 2 is a flowchart illustrating a block chain-based digital certificate processing method in an embodiment, and provides a block chain-based digital certificate processing method, which is described by taking an example that the method is applied to the first terminal 110 in fig. 1, and includes the following steps:
step S201, a digital certificate to be processed is acquired.
The digital certificate is also called a voucher or token, and each node of the blockchain system can perform corresponding operations on the digital certificate, for example, transfer the digital voucher to other nodes. In this step, the first terminal 110 may obtain the digital certificate as a to-be-processed digital certificate before transferring the digital certificate.
Step S202, obtaining certificate operation information and certificate verification information corresponding to the digital certificate through a first intelligent contract deployed in a first block chain system.
Wherein the first intelligent contract may be preset by the issuer of the digital voucher (the initial creator or the first owner) based on the operations that the digital voucher may perform and the verification rights requirements required for the operations. In this step, the first intelligent contract may be configured to determine the corresponding certificate operation instruction and the certificate verification information according to the certificate identification feature of the digital certificate to be processed. The certificate identification feature may be a value size or the like corresponding to the digital certificate. That is, for digital certificates with different certificate identification characteristics, the first intelligent contract may correspondingly output different certificate operation information and certificate verification information, and the first terminal 110 obtains the certificate operation information and the certificate verification information corresponding to the digital certificates. The credential operation information can be used to determine what operation the digital credential can be performed in the first blockchain system, and the credential validation information can be used to authorize validation of the digital credential by a particular node of the first blockchain system.
Step S203, determining a certificate verification node in the first blockchain system for verifying the digital certificate, and sending the certificate verification information to the certificate verification node.
This step is mainly to determine a node in the first blockchain system for verifying the digital certificate to be processed, which is called a certificate verification node (the certificate verification node may be the server 120 shown in fig. 1). Specifically, the first terminal 110 may send the credential verification information obtained in step S202 to the credential verification node for verification after determining the credential verification node.
Step S204, obtaining the certificate authorization information of the certificate verification node on the certificate verification information, and verifying the certificate authorization information by using a second intelligent contract deployed in the first block chain system to obtain an authorization verification result of the certificate verification node.
In this step, after the credential verification node verifies the credential verification information and obtains the credential authorization information, the first terminal 110 may receive the credential authorization information fed back by the credential verification node, and then the first terminal 110 may verify the credential authorization information by using a second intelligent contract deployed in the first block chain system, and is mainly used to verify whether the credential authorization information is generated by the credential verification node, so as to obtain an authorization verification result of the credential verification node, where the authorization verification result may include a pass verification result and a fail verification result. If the verification is passed, the certificate authorization information is issued by the certificate verification node, otherwise, whether the certificate authorization information is issued by the certificate verification node is uncertain.
Step S205, if the authorization verification result is that the verification is passed, processing the digital certificate according to the certificate operation information.
In this step, if the authorization verification result is that the verification is passed, the first terminal 110 may process the digital certificate according to the obtained certificate operation information. Taking the transfer process of the digital certificate as an example, the first terminal 110 may transfer the digital certificate to the second terminal 130 if the verification passes. And if the verification is not passed, the processing of the digital voucher can be stopped.
The digital certificate processing method based on the block chain obtains a data certificate to be processed, then obtains a certificate operation instruction and certificate verification information corresponding to the data certificate through a first intelligent contract deployed in a first block chain system, then determines a certificate verification node used for verifying the digital certificate, sends the certificate verification information to the certificate verification node for verification, then obtains the certificate authorization information of the certificate verification node for the certificate verification information, verifies through a second intelligent contract to obtain an authorization verification result of the certificate verification node, and processes the digital certificate according to the certificate operation information if the authorization verification result is a verification pass, the scheme can enable the digital certificate to be authorized and verified through each verification node of the chain block chain system before being transferred, and further checking each verification node, and processing the digital certificate according to the corresponding certificate operation information after the verification is passed, so that the safety of processing the digital certificate by the block chain system is improved.
In one embodiment, the credential operation information may include a credential transfer instruction; the processing of the digital certificate according to the certificate operation information in step S205 may include:
determining receiving node account information for a credential receiving node in a first blockchain system; sending a certificate transfer request to a certificate receiving node according to the account information of the receiving node; and if a certificate transfer response returned by the certificate receiving node is received, performing certificate transfer processing aiming at the digital certificate with the certificate receiving node according to the certificate transfer instruction.
In this embodiment, the voucher operating information may include a voucher transfer instruction, and in this case, if the first terminal 110 determines that the authorization verification result is a verification pass, the digital voucher may be further transferred according to the voucher transfer instruction. Specifically, after determining that the authorization check passes, the first terminal 110 may determine receiving node account information of a credential receiving node in the first blockchain system, where the credential receiving node may be the second terminal 130 as shown in fig. 1, and the receiving node account information may be an address of the second terminal 130 in the first blockchain system. Then, the first terminal 110 may send a credential transfer request to the credential receiving node according to the receiving node account information, the credential receiving node may respond to the credential transfer request, and feed back the credential transfer response to the first terminal 110, and if the first terminal 110 receives the credential transfer response returned by the credential receiving node, the first terminal 110 may perform transfer processing for the digital credential with the credential receiving node according to the credential transfer instruction. The first terminal 110 may split and transfer part of the digital certificate to the second terminal 130 according to the certificate transfer instruction, or may completely transfer the digital certificate to the second terminal 130, and the first terminal 110 may wait for the transfer of the digital certificate to be completed.
Further, the performing, according to the credential transfer instruction, the credential transfer process for the digital credential with the credential receiving node may specifically include:
establishing a credential transfer link with a credential receiving node; determining a voucher transfer time limit for the digital voucher according to a voucher transfer instruction; if the digital certificate is not transferred to the certificate receiving node within the certificate transfer time limit, the certificate transfer link is disconnected.
Specifically, after the first terminal 110 receives the credential transfer response of the credential receiving node, a credential transfer link may be further established with the credential receiving node, and a transfer process for the digital credential may be performed with the credential receiving node based on the transfer link. After the first terminal 110 establishes the credential transfer link with the credential receiving node, the credential transfer time limit for the digital credential may be determined according to the credential transfer instruction, where the credential transfer time limit is used to limit the usage time limit of the first terminal 110 and the credential receiving node on the credential transfer link, so as to avoid the problem of network resource waste caused by establishing a link for a long time without transferring the digital credential. If the digital voucher is not transferred from the first terminal 110 to the voucher receiving node within the voucher transfer time limit, the voucher transfer link is broken. In addition, if the first terminal 110 has transferred the digital certificate to the certificate receiving node within the certificate transfer time limit, the certificate transfer link may also be disconnected to save network resources.
In one embodiment, the first intelligent contract is further used for determining corresponding oriented verification node account information according to the certificate identification characteristics; determining a certificate verification node in the first blockchain system for verifying the digital certificate in step S203 may include:
according to the account information of the directional verification node, determining the directional verification node in the first block chain system corresponding to the account information of the directional verification node; and the oriented verification node is used as a certificate verification node for verifying the digital certificate.
In this embodiment, the first intelligent contract is further configured to determine corresponding directional verification node account information according to the certificate identification feature of the digital certificate, that is, when the first terminal 110 executes the first intelligent contract, directional verification node account information output by the first intelligent contract is obtained, where the directional verification node account information is account information corresponding to a directional verification node in the first block chain system, and the directional verification node is configured to verify the digital certificate. Specifically, the first terminal 110 may determine, according to the directional verification node account information, a directional verification node corresponding to the directional verification node account information in the first blockchain system, and use the directional verification node as a certificate verification node for verifying the digital certificate. The present embodiment can be used for implementing a scenario that requires directional authentication for a specific digital certificate, and the certificate identification feature can be the value of the digital certificate, so that different directional authentication nodes can be set according to the value of the digital certificate. The digital certificate can also be used for setting a fixed directional verification node for a specific certain type of digital certificate by utilizing the certificate identification characteristic of the digital certificate.
In an embodiment, the determining, according to the directional verification node account information, a directional verification node in the first blockchain system corresponding to the directional verification node account information may specifically include:
sending a block link point registration request to a directional verification end corresponding to the directional verification node account information; the block chain link point registration request is used for registering a directional verification end as a first block chain node in a first block chain system; and if the oriented verification end is registered as the first block chain node, setting the first block chain node as the oriented verification node.
In this embodiment, the first terminal 110 may invite the verification-oriented node that is not originally in the first blockchain to register as a node of the first blockchain system, that is, if the verification-oriented node has not been uplink, it may invite the verification-oriented node to register as a node. Specifically, the first terminal 110 may send a block link point registration request to the targeted authentication end corresponding to the targeted authentication node account information, for example, may send a short message registration link to a mobile phone of the targeted authentication node account, so that the targeted authentication end is registered as the first block link node in the first block link system. If the oriented verification terminal is successfully registered as the first block chain node on the first block chain system, the first block chain node is set as the oriented verification node, so that the oriented verification node can be requested to perform verification processing on the certificate verification information subsequently.
In some embodiments, the directional verification node account information may include second blockchain link point account information of the directional verification end in a second blockchain system; the sending of the block link point registration request to the directional verification end corresponding to the directional verification node account information may further include:
sending a block chain node registration request to a second block chain node in a second block chain system corresponding to second block chain node account information through a cross-chain server; the block link point registration request is further used for sending the account information of the second block link point to the cross-link server for auditing by the second block link point; obtaining an auditing result of account information of the second block chain link points fed back by the cross-link server; and if the verification result is that the verification is passed, creating a first block chain node according to the account information of the second block chain link point.
In this embodiment, the first terminal 110 may provide a cross-link authorization verification service through a third-party node of the cross-link service, so that the related information is imported into the chain to become a new node. Specifically, if the directional verification end is on the second block chain system, the first terminal 110 may obtain second block chain link point account information of the directional verification end in the second block chain system from the directional verification node account information, then send a block chain node registration request to a second block chain link point corresponding to the second block chain link point account information of the second block chain system terminal through the cross-chain server, so that the second block chain link node sends the second block chain link point account information to the cross-chain server for auditing after receiving the block chain link point registration request, the cross-chain server may audit the second block chain link point account information, send the obtained audit result to the first terminal 110, and if the audit result is that the audit is passed, the first terminal 110 may import the second block chain link point account information into the first block chain system through the cross-chain server, a first blockchain node is created. The scheme of the embodiment can safely and efficiently register the node originally positioned in the second block chain system as the oriented verification node of the first block chain system by endorsing the qualified cross-chain service third-party node.
In one embodiment, the determining a certificate verification node in the first blockchain system for verifying the digital certificate in step S203 may include:
acquiring account information of an invitation verification node; and determining a corresponding invitation verification node in the first blockchain system according to the account information of the invitation verification node, and taking the invitation verification node as a certificate verification node for verifying the digital certificate.
The embodiment is mainly that the first terminal 110 may invite one or more invitation verification nodes to verify the digital certificate in the first blockchain system. Specifically, the first terminal 110 may obtain account information of an invitation validation node, where the account information of the invitation validation node may be input to the first terminal 110 by a user, and then the first terminal 110 determines a corresponding invitation validation node in the first blockchain system according to the account information of the invitation validation node, and directly uses the invitation validation node as a credential validation node.
The above embodiment adopts a form of inviting one or more invitation authentication nodes to authenticate the digital certificate, and it should be noted that this way can be combined with a way of directing authentication nodes to authenticate the digital certificate, that is, after the invitation authentication nodes and the directing authentication nodes are determined, the invitation authentication nodes and the directing authentication nodes are jointly used as the certificate authentication nodes.
The technical solution of the embodiment of the present application is described with reference to fig. 3, and fig. 3 is a schematic flow chart of a block chain-based digital certificate processing method in an application example, and a main idea of the application example is to set a verification rule that needs to be satisfied when a digital certificate (also called a voucher or token) is correspondingly operated through an intelligent contract to obtain a verification contract of the digital certificate, and when the block chain system triggers the digital certificate verification contract in the operation process, the intelligent contract is operated to verify the voucher, and after the verification succeeds, the further operation of the voucher can be performed. The method comprises the following specific steps:
at step s1, the credential issuer (initial creator and first owner) writes into the smart contract the operations that can be performed by the credential and the rights requirements required for the operations when issuing the credential. The general evidence-passing operation can comprise transfer (namely transaction) and partial transaction (namely split transaction), the required authority can be adjusted according to the value of the evidence-passing, an issuer can be graded into several grades, for example, 100 ten thousand evidence-passing transactions need third-party signature authorization, 1 ten thousand face-value evidence-passing transactions need endorsement of any common third-party node, and 100 face-value evidence-passing transactions only need to be agreed by a buyer and a seller. In this regard, the issuer may also specify a fixed verification node, such as by enforcing that an authorized verification of the premise administration node must be obtained in the real estate transaction.
And step s2, when the certification owner initiates the transaction or part of the transaction, the intelligent contract feeds back the required authentication authority requirement according to the amount involved.
At step s3, the transaction initiator invites the node to authenticate, and may invite multiple nodes.
At step s31, if there is a mandatory directed verification node, the operation request is automatically sent to the directed verification node. If the mandatory node does not uplink, the node can be invited to register as the node, or a cross-link authorization verification service is provided by a cross-link service third-party node to obtain verification authorization.
And step s32, waiting for node signature authorization, and entering the subsequent steps when the authorization requirement meets the requirement of the intelligent contract without waiting for all node signatures.
At step s4, the smart contract verifies that the signed authorization node meets the requirements and that the total authorization meets the operational minimum requirements. If the requirement is met, the intelligent contract is accessed to the evidence-passing intention buyer node to wait for the transaction to be completed. Otherwise the transaction request is rejected.
The application example can allow a third party or multiple parties to participate in the certification transaction, carry out endorsement authorization and assist in verifying the legitimacy of the certification, and the nodes have high flexibility in the scheme for participating in verification, can realize transaction supervision of different levels through multiple tags, and can appoint directional nodes to participate in authorization operation if special transactions need strong supervision, so that the data security of the certification transaction processing is improved.
