[0065] The user information refers to the user's personal identity information, such as the user's name, contact information, etc.; the corresponding user's online payment information refers to the information generated by the user's online payment, such as the order items, payment amount, etc.;

[0066] Furthermore, in an optional embodiment of the present invention, the authentication signature function includes:

[0067] fakeMd5 expect =∑md5 i

[0068] Among them, fakeMd5 expect Indicates the financial information of the title confirmation, md5 i represents the bound financial information, and i represents the number of users.

[0069] Furthermore, the embodiment of the present invention can effectively detect whether the confirmation of the financial information is complete by utilizing the detection nodes of the detection network to perform confirmation authentication on the financial information, thereby ensuring that subsequent protection actions for the financial information can be carried out smoothly.

[0070] As an embodiment of the present invention, the use of the detection node of the detection network to perform authentication on the financial information includes: using the authentication function in the detection node to calculate the authentication value of the financial information, if the authentication value is less than a preset authentication value, the authentication of the financial information fails, if the authentication value is not less than the preset authentication value, the authentication of the financial information succeeds.

[0071] Furthermore, in an optional embodiment of the present invention, the right confirmation authentication function includes:

[0073] Among them, W(x) represents the authentication value, fakeMd5 expect represents the financial information of title confirmation, μ represents the average value vector of the financial information of title confirmation, and α represents the discriminant coefficient.

[0074] Furthermore, in an optional embodiment of the present invention, the preset authentication value may be set to 0.8, or may be set according to an actual business scenario.

[0075] S3. After the ownership confirmation authentication of the ownership confirmation financial information is successful, a consensus mechanism is created for the ownership confirmation financial information using the consensus nodes in the storage network to obtain consensus financial information, and consensus authentication is performed on the consensus financial information using the monitoring nodes in the detection network.

[0076] It should be understood that after the successful authentication of the ownership of the financial information, it means that only authorized users can access the ownership of the financial information. Therefore, the embodiment of the present invention uses the consensus nodes in the storage network to create a consensus mechanism for the financial information to obtain consensus financial information, which can ensure the consistency of the transmission of the financial information; wherein, the consensus node refers to the node used to specify rules and make participants agree; the consensus financial information refers to data that all nodes agree on and jointly recognize.

[0077] As an embodiment of the present invention, see Figure 3 As shown, the consensus nodes in the storage network are used to create a consensus mechanism for the confirmed financial information to obtain consensus financial information, including:

[0078] S301, using the consensus node to configure the consensus rules of the financial information confirmation;

[0079] S302, querying the information block node of each financial information in the title confirmation financial information, and distributing the consensus rule to each of the information block nodes;

[0080] S303: The consensus rules are authenticated by the information block nodes, and after the consensus authentication of the consensus rules is successful, the consensus financial information is generated.

[0081] Among them, the consensus rules refer to a set of rules that all participants need to abide by; the information block node means that each participant is equivalent to a block node; further, in an optional embodiment of the present invention, the distribution of the consensus rules to each of the information block nodes can be achieved through cryptographic principles.

[0082] Furthermore, the embodiment of the present invention can ensure that the consensus financial information is successfully reached by using the monitoring nodes in the detection network to perform consensus authentication on the consensus financial information, thereby continuing to effectively protect the data; wherein the monitoring node refers to a node used to determine whether the consensus financial information is successfully reached.

[0083] It should be noted that the consensus authentication of the consensus financial information is the same as the principle of the title authentication of the above-mentioned title confirmation financial information, and will not be further elaborated here.

[0084] S4. After the consensus authentication of the consensus financial information is successful, a smart contract of the consensus financial information is created using the smart contract node in the storage network to obtain contract financial information, and the contract financial information is authenticated using the monitoring node in the detection network.

[0085] It should be understood that after the consensus authentication of the consensus financial information is successful, it means that the consensus financial information has been recognized by all users. Therefore, the embodiment of the present invention uses the smart contract node in the storage network to create a smart contract for the consensus financial information, which can improve the trust of the participants in information transactions while improving the security of data transmission; wherein, the smart contract node refers to a node used to establish a mutually binding agreement between the participants, and the contract financial information refers to the consensus financial information after the contract is created.

[0086] As an embodiment of the present invention, the method of using the smart contract node in the storage network to create the smart contract of the consensus financial information to obtain the contract financial information includes: using the connection function in the smart contract node to construct an information transmission channel for the consensus financial information; using the configuration function in the smart contract node to configure the data contract of the consensus financial information; according to the information transmission channel, using the sending function in the smart contract node to send the data contract to the user end corresponding to the consensus financial information, so as to sign the data contract through the user end to obtain the contract financial information.

[0087] Among them, the connection function refers to the channel function used to create the information interaction in the consensus financial information, the configuration function refers to the function used to create the mutual agreement rules of the consensus financial information, the data contract contract refers to the smart contract of the consensus financial information created by the configuration layer, and the sending function refers to the algorithm for sending data to the user end. Optionally, the connection function, the configuration function and the sending function can be compiled by a programming language, such as JAVA language

[0088] Furthermore, the embodiment of the present invention can ensure the successful signing of the contract by performing contract authentication on the contract financial information using the monitoring node in the detection network, thereby protecting data security, wherein the monitoring node refers to a node used to detect whether the data contract is signed successfully.

[0089] S5. After the contract authentication of the contract financial information is successful, the contract financial information is distributedly stored using the storage nodes in the storage network to obtain distributed financial information.

[0090] It should be understood that after the contract authentication of the contract financial information is successful, it means that the user must use the contract financial information in accordance with the contract requirements. Therefore, the embodiment of the present invention uses the distributed nodes in the storage network to perform distributed information storage on the contract financial information to obtain distributed financial information, so as to realize the decentralized processing of the contract financial information, reduce storage costs, and greatly reduce the possibility of data loss due to database damage, thereby improving the data security of the contract financial information; wherein, distributed financial information refers to the data set of each node after the contract financial information is distributed to each storage node through the distributed nodes.

[0091] As an embodiment of the present invention, the method of using the storage nodes in the storage network to perform distributed information storage on the contract financial information to obtain distributed financial information includes: using the sharding function in the storage node to perform data sharding on the contract financial information to obtain sharded financial information; using the replication algorithm in the storage node to perform shard replication on the sharded financial information to obtain sharded replicated financial information; and using the distributed algorithm in the storage node to perform distributed storage on the sharded replicated data to obtain the distributed financial information.

[0092] Among them, the sharding function refers to a function that divides the entire data into smaller fragments of data through calculation, the sharded financial information refers to dividing the data into smaller fragments of data in the storage node, and the sharded replicated financial information means that the storage system will replicate the shard data obtained from each shard, so the sharded replicated financial information has sufficient redundant copies to ensure the availability and performance of the sharded replicated financial information, thereby preventing data loss of the sharded replicated financial information.

[0093] It can be seen that the embodiment of the present invention first obtains the financial online payment information in the terminal device and creates a blockchain network environment for the financial online payment information, which can provide a trusted network for the information security processing of the financial online payment information. Secondly, the embodiment of the present invention uses the confirmation node in the storage network to confirm the financial online payment information and obtain the confirmed financial information. The ownership of the financial online payment information can be protected by controlling the authority. Further, the embodiment of the present invention uses the consensus node in the storage network to create a consensus mechanism for the confirmed financial information to obtain the consensus financial information, which can ensure the consistency of the transmission of the confirmed financial information. Next, the embodiment of the present invention uses the smart contract node in the storage network to create the smart contract of the consensus financial information, which can improve the trust of the participants in the information transaction and improve the security of data transmission. Finally, the embodiment of the present invention uses the distributed nodes in the storage network to store the contract financial information in a distributed manner to obtain distributed financial information, so as to realize the decentralized processing of the contract financial information, reduce the storage cost, and greatly reduce the possibility of data loss due to database damage, thereby improving the data security of the contract financial information. Therefore, the information security protection method for blockchain finance and online payment proposed in the embodiment of the present invention can improve the security of financial information.
