The present invention provides an embodiment of an information sharing method, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that in the present disclosure, and the information sharing method is applied to a distributed ledger platform and an information sharing platform connected to the distributed ledger platform. The information sharing platforms connected with the distributed account book platform are provided with a plurality of information sharing platforms, and each information sharing platform can send transaction information generated by the self terminal to other information sharing platforms connected with the distributed account book platform through the distributed account book platform. In the application, an information sharing platform for sending transaction information to a distributed account book platform is called an information sending party, an information sharing platform for receiving shared information sent by the distributed account book platform is called an information receiving party, and each information sharing platform connected with the distributed account book platform has two identities which can be used as the information sending party and the information receiving party.
As shown in fig. 2, in a first embodiment of the present application, an information sharing method of the present application is applied to a distributed ledger platform, and the method includes the following steps:
step S210: and receiving shared information sent by a first node connected with the distributed account book platform.
In this embodiment, the distributed ledger platform refers to a Corda distributed ledger platform, which is a set of distributed ledger system, and the Corda distributed ledger platform is externally provided with a plurality of connection nodes, which are referred to as second nodes in this application. The first node is an information sharing platform connected with a second node of the Corda distributed account book platform, the identity of the first node is an information sender, and if the plurality of first nodes are connected with the second node of the Corda distributed account book platform, the second node of the Corda distributed account book platform comprises the plurality of first nodes. The shared information is generated according to the transaction information of the first node, namely after the transaction initiator and the transaction receiver transact through the first node, the first node acquires the transaction information generated in the transaction process, after receiving the transaction information, the first node judges whether the received transaction information meets the information sharing condition according to the intelligent contract stored by the first node, and when the first node determines that the received transaction information meets the information sharing condition through the intelligent contract, the shared information is generated according to the received transaction information.
Specifically, the intelligent contract may be that after the first node establishes a connection with a connection node of the Corda distributed ledger platform, the Corda distributed ledger platform actively sends the Corda distributed ledger platform to the first node, or that a user at the first node end downloads the Corda distributed ledger platform in advance and then imports the Corda distributed ledger platform to the first node. An intelligent contract is a computer protocol intended to propagate, validate or execute contracts in an informational manner. The intelligent contract comprises a judgment rule for detecting transaction information to generate shared information and a trigger instruction for generating the shared information, wherein the judgment rule is also negotiated between the first node and the third node, for example, a period that the first node generates the shared information once in 36 hours is set, and then the first node sends the trigger instruction for generating the shared information through the intelligent contract after detecting that the time for generating the shared information is reached through the intelligent contract so as to execute the generation operation of the shared information. After the shared information is generated, the first node sends the shared information to the Corda distributed account book platform, and the Corda distributed account book platform receives the shared information sent by the first node connected with the first node.
The intelligent contract further comprises a first node and a third node which are mutually in information sharing, wherein the third node is also an information sharing platform connected with the second node of the Corda distributed account book platform, the identity of the third node is an information receiving party, and if the plurality of third nodes are connected with the second node of the Corda distributed account book platform, the second node of the Corda distributed account book platform comprises the plurality of third nodes. The first node and the third node which mutually perform information sharing are written into the intelligent contract after the information sharing protocol is achieved in advance. The first node can know which specific third node the generated sharing information needs to be sent to according to the intelligent contract. For example, the first node 1 wants to perform information sharing with the third node 1, the third node 2, and the third node 3, after the first node 1 and the third node 1, the third node 2, and the third node 3 reach the information sharing protocol, the shared information generated by the first node 1 is sent to the third node 1, the third node 2, and the third node 3 through the Corda distributed account book platform, and similarly, the shared information generated by each of the third node 1, the third node 2, and the third node 3 is sent to the first node 1 through the Corda distributed account book platform. The smart contract includes, in addition to the above, other contents such as a data structure for generating shared information, verification of shared information, and the like.
Step S220: and determining a third node which is connected with the distributed account book platform and shares information with the first node in the second nodes according to the shared information.
In this embodiment, the shared information includes the second identity information of the third node, the first identity information of the first node, and the transaction information from the first node. After receiving the shared information sent by the first node connected with the Corda distributed account book platform, the Corda distributed account book platform analyzes the shared information to obtain first identity information and second identity information included in the shared information, then determines which first node the first identity information specifically corresponds to according to the first identity information, determines which third node the second identity information specifically corresponds to according to the second identity information, and then determines the third node corresponding to the second identity information as the third node performing information sharing with the first node corresponding to the first identity information. For example, if the first identity information is a0 and the second identity information is a2, then the Corda distributed ledger platform determines that the third node corresponding to a2 is the third node for information sharing with the first node corresponding to a 0.
Step S230: and sending the sharing information to the third node.
In this embodiment, after determining a third node performing information sharing with the first node, the Corda distributed ledger platform forwards the shared information to the third node, and the third node verifies the shared information through the intelligent contract. The third node acquires the first identity information of the first node which carries out information sharing with the third node through the intelligent contract, then the first identity information of the first node included in the shared information is compared with the third identity information, if the first identity information and the second identity information are the same, the shared information is verified to be passed, then the shared information is signed and stored, and further users can use the shared information through the third node.
According to the technical scheme, the sharing information sent by the first node connected with the distributed account book platform is received, the third node which shares information with the first node in the second node connected with the distributed account book platform is determined according to the sharing information, and the sharing information is sent to the third node.
As shown in fig. 3, based on the first embodiment, the second embodiment of the present application further includes the following steps before step S210:
step S211: and when receiving the connection request sent by the first node, sending the connection request to a third node in the second nodes so that the third node decrypts the connection request.
In this embodiment, the first node and the third node that need to perform information sharing with each other may previously establish an information sharing protocol, and after the information sharing protocol is written in the intelligent contract, the first node and the third node may apply for joining in the Corda distributed account book platform. The first node and the third node can both serve as an information sender and an information receiver, so that the first node and the third node apply for joining the Corda distributed account book platform in the same manner.
Specifically, taking a process of a first node applying for joining a Corda distributed account book platform as an example, the connection request is generated according to first identity information of the first node and an identification Certificate, and the identification Certificate is a Certificate issued by a Certificate Authority (CA), which is called a CA Certificate.
The first node acquires self first identity information and a preset identity recognition certificate, then acquires a private key stored in the first node in advance, encrypts the self first identity information and the identity recognition certificate through the private key to generate a connection request added into the Corda distributed account book platform, and then sends the connection request to the Corda distributed account book platform, namely the connection request is sent to the Corda distributed account book platform in a ciphertext mode. After receiving the connection request from the first node, the Corda distributed account book platform forwards the connection request to each third node in the second node of the Corda distributed account book platform, and after receiving the connection request from the first node sent by the Corda distributed account book platform, each third node in the second node decrypts the connection request, that is, decrypts the connection request through a public key stored in the Corda distributed account book platform in advance. If the public key of the third node is matched with the private key of the first node which generates the connection request, namely the public key of the third node can decrypt the connection request encrypted by the private key of the first node, and if the public key of the third node is not matched with the private key of the first node which generates the connection request, namely the public key of the third node cannot decrypt the connection request encrypted by the private key of the first node, therefore, the decryption result of each third node in the second node decrypting the connection request is decryption success information or decryption failure information.
Step S212: and when a decryption result sent by the third node is received, establishing connection between the first node and a connection node in the distributed account book platform according to the decryption result.
Step S213: and sending a connection success notice to the sending terminal.
In this embodiment, after each third node in the second node decrypts the connection request, the decrypted result is sent to the Corda distributed ledger platform, and the Corda distributed ledger platform decides whether to connect the first node that sends the connection request with the second node (connection node) in the Corda distributed ledger platform according to the specific decrypted result. Specifically, the Corda distributed account book platform acquires the number of nodes of a third node with a decryption result being successful in decryption in the second node, and when the number of nodes is greater than or equal to the preset number of nodes, connection between the first node and a connection node in the distributed account book platform is established, that is, the connection node in the Corda distributed account book platform is connected with the first node through a standard JPA interface. Specifically, the Corda distributed ledger platform obtains the number of successfully decrypted results sent by all third nodes in the second node, and the number of successfully decrypted results is the number of successfully decrypted nodes, that is, the number of nodes of the successfully decrypted third nodes for the connection request, for example, there are 20 third nodes in the second node in total, and the number of successfully decrypted results counted by the Corda distributed ledger platform is also 20, which indicates that all the 20 third nodes successfully decrypt the connection request, and if the number of successfully decrypted results counted by the Corda distributed ledger platform is 18, which indicates that all the 18 third nodes successfully decrypt the connection request, there are 2 third nodes which fail to decrypt the connection request. In this embodiment, an adding requirement is set for the first node to add to the Corda distributed ledger platform, that is, when the number of nodes of the third node that succeeds in decrypting the connection request is greater than or equal to the preset number of nodes, the first node that sends the connection request is allowed to establish a connection with the second node (connection node) in the Corda distributed ledger platform. After the first node sending the connection request is allowed to establish connection with the second node by the Corda distributed account book platform, the first node sending the connection request is indicated to be successfully added into the Corda distributed account book platform. And then, the Corda distributed ledger platform generates a connection success notification and sends the connection success notification to the first node sending the connection request. After the Corda distributed ledger platform can decrypt the connection request through the public key stored in advance, the connection success notification is sent to the first node sending the connection request according to the first identity information in the connection request, and the public key in the Corda distributed ledger platform can successfully decrypt each received connection request. Further, after the first node sending the connection request successfully joins the Corda distributed account book platform, the Corda distributed account book platform obtains the intelligent contract stored by the Corda distributed account book platform, and sends the intelligent contract to the first node sending the connection request.
As shown in fig. 4, based on the first embodiment, the information sharing method in the third embodiment of the present application is applied to the first node, and the information sharing method includes the following steps:
step S310: transaction information is obtained.
In this embodiment, the identity of the first node is an information sender, and the transaction information refers to information generated during a transaction process between a transaction initiator and a transaction receiver, for example, transaction time information, account information of the transaction initiator, account information of the transaction receiver, and the like. After the transaction between the transaction initiator and the transaction receiver is completed, the first node acquires transaction information generated in the transaction process.
Step S320: and when the transaction information meets the intelligent contract, generating shared information according to the transaction information.
In this embodiment, the intelligent contract may be that after the first node establishes a connection with a connection node of the Corda distributed ledger platform, the Corda distributed ledger platform actively sends the Corda distributed ledger platform to the first node, or that a user at the first node end downloads the Corda distributed ledger platform in advance and then imports the Corda distributed ledger platform to the first node.
After the first node acquires the transaction information, a judgment rule for generating shared information according to the detected transaction information included in the intelligent contract is used for judging whether the acquired transaction information meets a shared information generation condition, and when the acquired transaction information meets the shared information generation condition, a generation operation of the shared information is executed according to a trigger instruction generated by the shared information included in the intelligent contract, namely the shared information is generated according to the transaction information. For example, the judgment rule for detecting the transaction information to generate the shared information is that the first node generates the shared information once when acquiring the preset number of transaction information, and then when the number of the transaction information acquired by the first node reaches the preset number, it indicates that the shared information needs to be generated according to the acquired transaction information.
