Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a data interaction method, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the data interaction method.
While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than presented herein.
In various embodiments of the data interaction method, for ease of description, various embodiments are illustrated with a body being executed by a node in a federation chain.
The terms used in this application are explained below:
a block chain is a chain of blocks, each block having a Hash value of the block recorded thereon in addition to the data of the block, and is thus formed into a chain. The block chain has two core ideas, one is a cryptography technology, the other is a decentralization idea, and based on the two ideas, historical information on the block chain cannot be tampered. A chunk consists of a chunk header and a chunk body, where the chunk header definition includes important fields such as the height of the chunk, the hash value of the last chunk, and the chunk body mainly stores transaction data.
Block chains can be classified into three categories, starting from the degree of openness of access rights (also called "decentralized degree"): public, private, and federation chains.
Each node of the federation chain usually has a corresponding entity organization, and can join and leave the network only after authorization. The alliance chain also belongs to the private chain in nature, but the nodes on the chain are controlled by multiple organizations, and the privatization degree is lower than that of the private chain. Meanwhile, the authority control between the two nodes is different, the read-write authority of the alliance chain faces all or part of the nodes on the chain, and the authority control design is more complex.
The node refers to a network node participating in a blockchain network for transaction and data exchange, each independent organization member can have one or more transaction nodes, and each transaction node is a combination of a group of physical networks, computers, blockchain application software and databases. The nodes are connected with each other by a TCP/IP (Transmission Control Protocol/Internet Protocol ) Protocol.
The data interaction method comprises the following steps:
step S10, when a receiving node in a federation chain receives an interaction request for data interaction, obtain first interaction information corresponding to the interaction request, where the federation chain is set in a server.
In this embodiment, the federation chain is provided in a server, and a node in the federation chain that receives an interaction request sent by a user through its terminal is referred to as a receiving node. After receiving the interactive request of data interaction, the receiving node acquires first interactive information corresponding to the interactive request. The interactive request can be triggered by a corresponding user according to needs, and the first interactive information includes but is not limited to a login account, an identity card number, a mobile phone number and the like. The login account is an account used for login after the user registers in the alliance chain. In this embodiment, if a user needs to perform data interaction with a node in a federation chain, the user needs to register in the federation chain and own a corresponding login account. It should be noted that the interactive request carries the first interactive information, so that after the receiving node receives the interactive request, the receiving node may extract the first interactive information from the interactive request to obtain the first interactive information.
Step S20, detecting whether the first interaction information exists in a white list and a first black list of each node of the federation chain, and obtaining a detection result.
In the alliance chain, each node has a black list and a white list, and nodes added into the alliance chain can share the black list and the white list. When the receiving node acquires the blacklist and the white list shared by other nodes in the alliance chain, the blacklist and the white list of the other nodes can be stored. In this embodiment, the blacklist corresponding to the receiving node and the blacklist shared by other nodes in the federation chain are referred to as a first blacklist. Each node in the alliance chain has a corresponding node identifier, and the node identifiers of the corresponding nodes are carried in the blacklist and the white list, so that the blacklist and the white list corresponding to each node can be distinguished through the node identifiers.
After the receiving node obtains the first interaction information corresponding to the interaction request, the receiving node detects whether the first interaction information exists in a white list and a first black list of each node of the alliance chain, and a detection result is obtained. It should be noted that, because one node corresponds to one black list and one white list, the obtained detection result has three situations, which are respectively: exists in a first blacklist; exist in the white list; or not in the first blacklist nor in the whitelist. Different detection results correspond to different result identifiers, and in this embodiment, the expression form of the result identifier is not limited, for example, the result identifier existing in the first blacklist may be set to "00", the result identifier existing in the white list may be set to "11", and the result identifier existing in neither the first blacklist nor the white list may be set to "01".
It should be noted that the detection results corresponding to different nodes also carry node identifiers, so as to distinguish the detection results of different nodes. If the node identifier of a certain node is "a", the corresponding detection result is that the node identifier exists in the first blacklist, and the corresponding detection identifier is "a 00". Therefore, the detection identifier is composed of the result identifier and the node identifier, and therefore the detection result corresponding to the first interaction information can be determined through the detection identifier. The composition manner of the result identifier and the node identifier is not limited in this embodiment.
Step S30, if the detection result meets a first preset condition, the interactive request is executed.
And after the receiving node obtains the detection result, the receiving node obtains a detection identifier corresponding to the detection result, and judges whether the detection result meets a first preset condition or not through the detection identifier. And if the detection result is determined to meet the first preset condition, the receiving node executes the interactive request and sends the interactive request to another terminal. It should be noted that the first preset conditions corresponding to different service scenarios may be different, for example, in a banking service scenario, the first preset condition may be set that a bank account cannot exist in a first blacklist of any node in a federation chain and needs to exist in a white list of at least two nodes in the federation chain; in a loan service scenario, the preset condition may be that the mobile phone number and/or the identity card number cannot be stored in the first blacklist of any node in the federation chain, and need to be stored in the white list of one node in the federation chain.
Further, if the receiving node determines that the detection result does not meet the first preset condition, the receiving node refuses to execute the interaction request, generates prompt information, and sends the prompt information to the terminal corresponding to the interaction request. And after receiving the prompt information, the terminal outputs the prompt information to prompt the user that the interactive request is refused to be executed according to the prompt information, or prompt the user that the interactive request is failed to be executed according to the prompt information, so that the user can know the execution result of the interactive request in time. In this embodiment, the output mode of the terminal for outputting the prompt message is not limited, for example, the prompt message may be output in a voice or text mode.
In the embodiment, after a certain node in a alliance chain receives an interaction request of data interaction, whether first interaction information corresponding to the interaction request exists in a white list and a first black list of each node in the alliance chain is detected, a detection result is obtained, if the detection result meets a first preset condition, the interaction request is executed, so that the interaction request is sent to another terminal, data interaction of a server is reduced through a decentralized characteristic of a block chain, data processing pressure of the server is reduced, and as each node in the alliance chain is independent from each other and only an authorized node can be added into the alliance chain, the reliability of the server is improved; furthermore, each node in the alliance chain shares a white list and a black list, so that the safety of data interaction is improved.
Further, a second embodiment of the data interaction method of the present invention is provided.
The second embodiment of the data interaction method differs from the first embodiment of the data interaction method in that, referring to fig. 2, the data interaction method further includes:
step S40, after detecting the registration request registered at the receiving node, detecting whether the registration request meets the registration condition of the federation chain.
When the receiving node detects the registration request, the receiving node detects whether the registration request meets the registration condition of the alliance chain. It should be noted that, in the federation chain, registration conditions are set in advance, and the registration conditions can be set according to specific needs. If there are 10 nodes in the federation chain, the registration condition may be set to determine that the registration request conforms to the registration condition of the federation chain only if all 6 nodes agree to perform the registration request.
Step S50, if the registration request meets the registration condition, executing the registration request, and after the registration request is successfully executed, detecting whether the interaction request is received.
If the registration request is determined to meet the registration condition, the receiving node executes the registration request, and after the registration request is successfully executed, namely the user successfully registers in the alliance chain, the receiving node detects whether the interaction request is received. It should be noted that, when a user successfully registers in a node in the federation chain, the user may perform data interaction in any node in the federation chain.
Further, if the registration request is determined not to meet the registration condition, the receiving node sends a prompt message to the terminal corresponding to the registration request. And after receiving the prompt message, the terminal outputs the prompt message and prompts the user that the registration fails according to the prompt message.
In the embodiment, in the registration process of the alliance chain node, whether the registration request meets the registration condition needs to be detected, and the registration request is executed only when the registration condition is met, so that the security of data interaction based on the alliance chain is further improved.
Further, a third embodiment of the data interaction method of the present invention is provided.
The third embodiment of the data interaction method differs from the second embodiment of the data interaction method in that, referring to fig. 3, the data interaction method further includes:
step S60, if the detection result does not meet the first preset condition, obtaining second interaction information corresponding to the interaction request.
And if the detection result is determined not to meet the first preset condition, the receiving node acquires second interaction information corresponding to the interaction request. The second interaction information is information corresponding to the receiving node wind control strategy, and the second interaction information can be different from the first interaction information and can also be the same as the first interaction information. In a alliance chain, the wind control strategy corresponding to each node is preset.
Step S70, acquiring a wind control policy corresponding to the receiving node, and detecting whether the second interaction information meets a second preset condition through the wind control policy.
And the receiving node acquires the wind control strategy of the receiving node, and detects whether the second interactive information meets a second preset condition or not through the wind control strategy. If the wind control strategy of a certain node is as follows: whether the bank card number exists in the black list or not and whether the identity card number exists in the white list or not are detected. If the bank card number of the user exists in the blacklist and/or the identity card number does not exist in the white list, the receiving node determines that the second interactive information does not accord with a second preset condition; and if the bank card number does not exist in the blacklist and the identity card number exists in the white list, the receiving node determines that the second interactive information meets a second preset condition.
Furthermore, the priority of the second interactive information can be set according to different types of the data interactive requests. If the data interaction request is a request for inquiring balance, setting the priority of the bank card account higher than that of the identity card number, and setting the priority of the identity card number higher than that of the mobile phone number; when the data interaction request is a loan request, the priority of the telephone number is higher than that of the identity card number, and the priority of the identity card number is higher than that of the login account. At this time, when the wind control policy is set, the wind control policy corresponding to the different types of data interaction requests may be set according to the priority of the second interaction information.
If the wind control strategy of the interactive request corresponding to the query balance can be set as follows: when the fact that the bank card account number does not exist in a blacklist of each node of the alliance chain and the identity card number or the mobile phone number exists in a white list of one node of the alliance chain is detected, the receiving node determines that the second interaction information meets a second preset condition; and when the bank card account number is detected to exist in a blacklist of one node in the alliance chain, and/or the identity card number or the mobile phone number does not exist in a white list of each node in the alliance chain, the receiving node determines that the second interaction information does not meet a second preset condition.
It should be noted that the determination condition corresponding to the wind control policy is different from the determination condition corresponding to the first preset condition. If the first preset condition of a certain node is: the bank account number cannot exist in a first blacklist of any node of the alliance chain, and the bank account number needs to exist in a white list of at least two nodes of the alliance chain, and the wind control strategy can be set as follows: the bank account number only needs to be absent from the blacklist of any node in the alliance chain.
Step S80, if the second interaction information meets the second preset condition, starting a manual review process, and detecting whether a review result is received.
And if the second interactive information is determined to meet the second preset condition, the receiving node generates audit prompt information, and sends the audit prompt information to an auditor, specifically, the audit prompt information can be sent to a terminal held by the auditor to prompt the auditor to audit the interactive request so as to start a manual audit process. And after the auditor audits the interaction request, inputting a manual audit result in an audit interface of the corresponding terminal. And after the terminal held by the auditor receives the audit result input by the auditor on the audit interface, sending the audit result to the receiving node.
Further, if it is determined that the second interaction information does not meet the second preset condition, the receiving node refuses to execute the interaction request.
And step S90, when the audit result is received and the interactive request is confirmed to pass the manual audit according to the audit result, executing the interactive request.
And after the receiving node receives the audit result, extracting the audit identifier in the audit result, and determining whether the interactive request passes the manual audit according to the audit identifier. And when the receiving node determines that the interactive request passes the manual review, the receiving node executes the interactive request. The auditing result comprises two types, wherein one type is approved, and the other type is not approved. Specifically, the audit flag of "pass audit" may be set to "1", and the audit flag of "fail audit" may be set to "0". It should be noted that the expression of the audit flag is not limited to that described in this embodiment, for example, the audit flag of "pass audit" may also be set to "a", and the audit flag of "fail audit" may also be set to "b".
Further, if the interactive request is determined not to pass the manual review according to the review result, the receiving node refuses to execute the interactive request.
In the embodiment, when it is determined that the detection result does not meet the first preset condition, whether the second interaction information of the interaction request meets the second preset condition is detected, when the second preset condition is met, manual review is performed, and after the interaction request passes the manual review, the interaction request is executed, so that the execution success rate of the interaction request is improved, and the success rate of data interaction is improved.
Further, a fourth embodiment of the data interaction method of the present invention is provided.
The fourth embodiment of the data interaction method differs from the first, second or third embodiment of the data interaction method in that step S80 includes:
step a, if the second interaction information meets the second preset condition, sending the second interaction information to other nodes in the alliance chain except the receiving node, so that the other nodes can detect whether the second interaction information exists in a corresponding second blacklist or not, and return a corresponding detection result, wherein each node in the alliance chain has a corresponding second blacklist.
In order to ensure the uniqueness of each node in the federation chain, each node in the federation chain must share a black list and a white list in a preset proportion, that is, each node in the federation chain is allowed to retain a part of the black list and/or the white list without sharing to other nodes in the federation chain. In this embodiment, the blacklist retained by each node is referred to as a second blacklist. The preset examples can be set according to specific needs, such as 70%, 80%, or 85%.
And when the second interaction information is determined to meet the second preset condition, the receiving node sends the second interaction information to other nodes except the receiving node in the alliance chain. When other nodes in the alliance chain receive the second interaction information, the other nodes detect whether the second interaction information exists in a corresponding second blacklist to obtain a detection result, and the detection result is sent to the receiving node. There is a corresponding second blacklist for each node in the federation chain.
It can be understood that the other node detecting whether the second interaction information exists in the corresponding second blacklist is detecting whether the second interaction information exists in the corresponding blacklist, which is not shared to the receiving node.
Further, in order to ensure the security of data interaction in the federation chain and ensure the flexibility and autonomy of each node in the federation chain, step a includes:
step a1, if the second interaction information meets the second preset condition, sending the second interaction information to other nodes in the alliance chain except the receiving node, so that the other nodes can determine the category of the second interaction information after receiving the second interaction information.
And if the second interaction information is determined to meet the second preset condition, the receiving node sends the second interaction information to other nodes except the receiving node in the alliance chain. And after other nodes in the alliance chain receive the second interaction information, determining the type of the second interaction information. The category of the second interactive information is preset, for example, the identification number and the bank card number can be set as a first category, and the mobile phone number and the login account number can be set as a second category.
Step a2, when it is determined that the second interaction information belongs to the first class, the other node detects whether the second interaction information exists in the corresponding second blacklist, and sends the obtained detection result to the receiving node.
When other nodes determine that the second interaction information belongs to the first type, other nodes in the alliance chain detect whether the second interaction information exists in a corresponding second blacklist, namely detect whether the information which is the same as the second interaction information is found in the second blacklist or not, obtain a detection result, and send the detection result to a receiving node in the alliance chain.
Step a3, when the second mutual information is determined to belong to the second class, the other nodes obtain the current resource utilization rate.
And when other nodes determine that the second interaction information belongs to the second class, the other nodes acquire the current corresponding resource utilization rate. Specifically, the resource utilization rate may be a Central Processing Unit (CPU) resource utilization rate.
Step a4, when the resource utilization rate is smaller than a preset threshold, detecting whether the second interaction information exists in the second blacklist, and sending the obtained detection result to the receiving node.
And when the other nodes acquire the corresponding resource utilization rate, the other nodes judge whether the resource utilization rate is smaller than a preset threshold value. And when the resource utilization rate is smaller than the preset threshold value, other nodes detect whether the second interactive information exists in a corresponding second blacklist to obtain a detection result, and the detection result is sent to the receiving node. And when the resource utilization rate is determined to be greater than or equal to the preset threshold value, other nodes refuse to detect whether the second interaction information exists in a corresponding second blacklist. The preset threshold may be set according to specific needs, and the specific value of the preset threshold is not limited in this embodiment.
Further, in order to improve the efficiency of data interaction, step a further includes:
step a5, if the second interaction information meets the second preset condition, sending the second interaction information to other nodes in the alliance chain except the receiving node, and detecting whether a waiting time sent by the other nodes is received, wherein the waiting time is the time from when the other nodes receive the second interaction information to when the detection result is obtained.
And after the second interactive information is determined to meet the second preset condition, the receiving node sends the second interactive information to other nodes except the receiving node in the alliance chain. And after the receiving node sends the second interaction information to other nodes, the receiving node detects whether the waiting time sent by other nodes is received, wherein the waiting time is the time from the other nodes receiving the second interaction information to the detection result. And after the other nodes receive the second interactive information, the other nodes determine the duration of the detection result according to the current resource utilization rate of the other nodes, namely determine the waiting duration, and send the waiting duration to the receiving node. It should be noted that, the mapping relationship between the resource utilization rate and the waiting duration may be stored in advance in other nodes, and the corresponding waiting duration may be determined according to the mapping relationship.
Step a6, when the waiting duration is received and the waiting duration is less than a preset duration, sending a detection request to the other node, so that the other node detects whether the second interaction information exists in the corresponding second blacklist after receiving the detection request, and returning a corresponding detection result.
After receiving the waiting duration, the receiving node determines whether the waiting duration is less than a preset duration, where the preset duration may be set according to specific needs, and in this embodiment, specific time corresponding to the preset duration is not limited. And when the receiving node determines that the waiting time is less than the preset time, the receiving node sends a detection request to other nodes. And after receiving the detection request, other nodes detect whether the second interactive information exists in a corresponding second blacklist according to the detection request to obtain a detection result, and send the detection result to the receiving node. Further, when the receiving node determines that the waiting time is longer than or equal to the preset time, the receiving node sends a prohibition request to other nodes. And after other nodes receive the prohibition request, other nodes prohibit the detection of whether the second interactive information exists in the corresponding second blacklist according to the prohibition request.
And b, after the detection result is received, determining the number of the blacklists of the second interactive information searched in the second blacklist according to the detection result.
And when the receiving node receives the detection result, the receiving node determines that the number of the blacklists of the second interactive information is found in the second blacklists corresponding to other nodes according to the detection result. It can be understood that the number of the blacklists can be determined according to the detection identifiers, that is, the number of the blacklists can be determined according to the number of the identifiers existing in the second blacklist carried in the detection result. And if the detection result carries 3 identifiers in the second blacklist, determining that the number of the blacklists is 3.
And c, if the number of the blacklists is less than or equal to the preset number, executing the interactive request.
And after the receiving node determines the number of the blacklists, the receiving node judges whether the number of the blacklists is less than or equal to a preset number. And when the number of the blacklists is determined to be less than or equal to the preset number, the receiving node executes the interaction request. Wherein the preset number can be set according to the total number of nodes in the alliance chain. If there are 6 nodes in the federation chain, the receiving node will execute the interaction request only if the number of blacklists is less than or equal to 2.
Further, when the receiving node determines that the number of the blacklists is greater than the preset number, the receiving node refuses to execute the interaction request.
