The application environment and the hardware structure and function of the related devices of the various embodiments of the present invention have been described in detail so far. Hereinafter, various embodiments of the present invention will be proposed based on the above-described application environment and related devices.
First, the present invention provides a block chain-based federation member management apparatus 200.
Fig. 2 is a block diagram of an embodiment of a device 200 for managing coalition members based on blockchain according to the present invention.
In this embodiment, the blockchain-based federation member management apparatus 200 includes a series of computer program instructions stored on the memory 11 that, when executed by the processor 12, may implement the blockchain-based federation member management functionality of the embodiments of the present invention. In some embodiments, the blockchain-based federation member management apparatus 200 may be divided into one or more modules based on the particular operations implemented by the portions of the computer program instructions. For example, in fig. 2, the block chain-based federation member management apparatus 200 may be partitioned into a receiving module 201, an obtaining module 202, a querying module 203, a monitoring module 204, and an adjusting module 205. Wherein:
the receiving module 201 is configured to receive service data information uploaded by a first alliance member through a node device.
In the present embodiment, for example, the block-chain-based federation member management apparatus 200 is applied to a financial information federation block chain based on Fabric technology, the financial information federation block chain being used for storing information including user information, financial institution information, financial transaction information, and all information related to the user, financial institution and financial transaction. In this embodiment, each financial institution may log in to the financial information federation block chain through a block chain node device, add, modify, and query block data, and the financial information federation block chain stores all block data and records an operation record of the block data. In this embodiment, the federation member management apparatus 200 based on a block chain and the financial information federation block chain run on the computer device 1, but of course, the computer device 1 may be any node device in the block chain. When a first financial institution uploads financial services, such as loan services, handled by a user to the financial information alliance block chain through a block chain node device, such as a PC terminal, a mobile device, and other terminal devices, then the receiving module 201 receives loan service data information uploaded by the first financial institution.
The obtaining module 202 is configured to obtain client information in the service data information, traverse client data stored in the block blocks of all the blocks, and search a white list of all client information including the client information.
Specifically, after the receiving module 201 receives the service data information, the client information corresponding to the service data information is acquired, and then the acquiring module 202 searches a client information white list including the client information according to the client information traversing the client data stored in the block bodies of all the blocks on the block chain network.
In this embodiment, after receiving the loan transaction information uploaded by the first financial institution, the receiving module 201 further obtains the customer information of the loan transaction information, and determines whether the customer information exists in a customer information white list, where the customer information white list is uploaded to the financial information federation block chain by a second financial institution. In this embodiment, the client information white list includes a type of client data having a potential of transacting loan services or transacting a similar loan service before, and the second financial institution obtains the client information white list through screening and sorting, or through a partner resource sharing manner, and then uploads the client information white list to the financial information federation block chain. Each financial institution can upload the customer data by means of a customer information white list, and the customer information white list uploaded by each financial institution is summarized into the customer information white list corresponding to the financial institution. That is, each coalition member may upload the customer information whitelist multiple times, but eventually all converge to a customer information whitelist for the coalition member. Therefore, after receiving the loan transaction information uploaded by the first financial institution, the obtaining module 202 further obtains the customer information corresponding to the loan transaction information, and then searches for a customer information white list including the customer information by traversing the customer data stored in the block bodies of all the blocks of the financial information alliance block chain.
The query module 203 is configured to select the first client information white list with the earliest link entry time when the client information white list including the client information is found, and query a second federation member uploading the first client information white list.
Specifically, after the obtaining module 202 finds out all the client information white lists including the client information, the querying module 203 selects a client information white list with the earliest creation time, that is, a first client information white list with the earliest link entry time, from all the found client information white lists, and queries a second affiliate member uploading the first client information white list. In this embodiment, after the obtaining module 202 obtains all the client information white lists including the client information corresponding to the loan service, the querying module 203 selects the client information white list with the earliest creation time, and queries the second financial institution that uploads the client information white list.
The monitoring module 204 is configured to monitor a data state of at least one service node in a preset service period of the service data information, and determine whether the data state is abnormal.
Specifically, the monitoring module 204 obtains a state value of the service data information at the service node, then compares the state value with a state value corresponding to the service node, and if the state value is not consistent with the state value, determines that the data state of the service data information is abnormal.
In this embodiment, the status value of the service node, for example, for the loan service, may be considered as a payment date and a payment amount. The monitoring module 204 monitors the service data information including repayment date and repayment amount by acquiring repayment records of the first financial institution about the client for the loan service; then, the monitoring module 204 compares the repayment date and the repayment amount in the service data information with the repayment date and the repayment amount of the service node status value, and when the repayment date in the service data information is later than the repayment date of the service node status value or the repayment amount in the service data information is smaller than the repayment amount of the service node status value, it is determined that the data status of the loan service information is abnormal.
The adjusting module 205 is configured to transfer the client information to a preset client information blacklist when the data state is abnormal, and adjust the integrity value of the second federation member according to a preset integrity value calculation rule; and the coalition members with the integrity values lower than a preset threshold value limit the permission of uploading data.
Specifically, when the monitoring module 204 monitors that the data state is abnormal, the adjusting module 205 may transfer the customer information to a preset customer information blacklist and adjust the integrity value of the second affiliate member according to a preset integrity value calculation rule. Of course, when the monitoring module 204 monitors that the data is not abnormal, the adjusting module 205 distributes the profits of the service data information to the first alliance member and the second alliance member according to a preset distribution rule. Wherein the allocation rule comprises: assigning a first percentage of the profit for the business data information to the first coalition member and a second percentage of the profit for the business data information to the first coalition member. The integrity value calculation rule is as follows: and the ratio of the number of the client information obtained by subtracting the number of the client information transferred to the client information black list from the client information white list uploaded by the coalition members to the total number of the client information white list is multiplied by 100. And the distribution rule and the integrity numerical value calculation rule are stored in the intelligent contract mode of the block chain by writing, and are stored in the block chain network for standardizing data operation behaviors on the block chain.
In this embodiment, when the user white list uploaded by the second financial institution is not of good quality, then the other financial institutions may cause frequent loss of trust after performing loan transaction according to the customer data of the customer information white list corresponding to the second financial institution. In this case, for example, the monitoring module 204 monitors the data status of the loan transaction information of the first financial institution to be abnormal. The adjusting module 205 transfers the customer information from the customer information white list corresponding to the second financial institution to a preset customer information black list, and then multiplies the ratio of the quantity of the customer information obtained by subtracting the quantity of the customer information transferred to the customer information black list from the customer information white list corresponding to the second financial institution by 100 to obtain the adjusted integrity value of the second financial institution. And the integrity value is used for adjusting the authority of the second financial institution, such as the authority of uploading authority service data (namely service handling authority). For example, the customer information white list uploaded by the second financial institution includes 100 pieces of customer information, and when the number of users in the customer information white list transferred to the customer information black list is 30, the corresponding integrity value of the second financial institution is (100-30)/100 × 100=70. When the integrity value is smaller than a preset threshold value, for example, 80, the adjusting module 205 performs permission degradation processing on the second financial institution, for example, the block chain-based coalition member management apparatus 200 presets a financial institution level system, for example, the financial institution level system is divided into 5 levels, each level has 20 integrity values, the lowest level of 1 is 0 to 20 integrity values, and the highest level of 5 is 81 to 100 integrity values, which are sequentially increased. The level is used to evaluate the credit rating of the financial institution, and when the credit rating of a financial institution is poor, for example, below a 4-level 60-loyalty value, the financial institution's total amount of financial transactions to be processed is limited.
Of course, if the monitoring module 204 monitors that the data status of the loan transaction uploaded by the first financial institution is not abnormal, the adjusting module 205 allocates the profits of the loan transaction to the first financial institution and the second financial institution respectively according to a preset allocation rule, for example, 80% of the profits are allocated to the first financial institution and 20% of the profits are allocated to the second financial institution.
As can be seen from the foregoing, the computer device 1 is capable of obtaining corresponding client information after receiving the service data information uploaded by the first coalition member; then, traversing the client data stored in the block bodies of all the blocks, and searching all client information white lists comprising the client information; then selecting a first customer information white list with the earliest link entering time, and querying a corresponding second union member; then monitoring the data state of the service data information in a preset service period; and when the data state is abnormal, transferring the client information to a preset client information blacklist and adjusting the integrity value of the second alliance member to adjust the authority. In this way, the state analysis of the business data and/or the client data uploaded by the coalition members is performed, so that the coalition members can be evaluated and managed fairly and effectively.
In addition, the invention also provides a block chain-based union member management method, which is applied to computer equipment.
Fig. 3 is a schematic flowchart illustrating an embodiment of a block chain-based federation member management method according to the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 3 may be changed and some steps may be omitted according to different requirements.
Step S500, receiving the service data information uploaded by the first alliance member through the node device.
In this embodiment, for example, the block-chain-based federation member management method is applied to a financial information federation block chain based on Fabric technology, where the financial information federation block chain is used to store information including user information, financial institution information, financial transaction information, and all information related to the user, financial institution and financial transaction. In this embodiment, each financial institution may log in to the financial information federation block chain through a block chain node device, add, modify, and query block data, and the financial information federation block chain stores all block data and records an operation record of the block data. In this embodiment, the financial information federation blockchain runs on a computer device, and of course, the computer device may be any node device in the blockchain. When a first financial institution uploads financial services, such as loan services, handled by a user to the financial information alliance block chain through a block chain node device, such as a PC (personal computer) terminal, a mobile device and other terminal devices, then a computer device receives loan service data information uploaded by the first financial institution.
Step S502, obtaining the client information in the service data information, traversing the client data stored in the block blocks of all the blocks, and searching all the client information white lists including the client information.
Specifically, after receiving the service data information, the computer device obtains client information corresponding to the service data information, and then searches a client information white list including the client information according to the client data stored by traversing block bodies of all blocks on the block chain network by the client information.
In this embodiment, after receiving the loan transaction information uploaded by the first financial institution, the computer device further obtains client information of the loan transaction information, and determines whether the client information exists in a client information white list, where the client information white list is uploaded to the financial information federation block chain by a second financial institution. In this embodiment, the client information white list includes a type of client data having a potential for transacting loan services or transacting similar loan services before, and the second financial institution obtains the client information white list by screening and sorting or by sharing partner resources, and then uploads the client information white list to the financial information federation block chain. Each financial institution can upload the customer data by means of a customer information white list, and the customer information white list uploaded by each financial institution is summarized into the customer information white list corresponding to the financial institution. That is, each coalition member may upload the customer information whitelist multiple times, but eventually all converge to a customer information whitelist for the coalition member. Therefore, after receiving the loan service information uploaded by the first financial institution, the computer device further obtains the customer information corresponding to the loan service information, then traverses the customer data stored in the block bodies of all the blocks of the financial information alliance block chain, and searches for a customer information white list including the customer information.
Step S504, a first customer information white list with the earliest link entering time is selected, and a second union member uploading the first customer information white list is inquired.
Specifically, after finding all the client information white lists including the client information, the computer device further selects a first client information white list with the earliest creation time, namely the first client information white list with the earliest link entry time, from all the found client information white lists, and then queries a second affiliate member uploading the first client information white list. In this embodiment, after acquiring all the client information white lists including the client information corresponding to the loan service, the computer device selects the client information white list with the earliest creation time, and then queries the second financial institution that uploads the client information white list.
Step S506, monitoring a data state of at least one service node in a preset service period of the service data information, and determining whether the data state is abnormal. Jumping to step S508 when the data state is abnormal; otherwise, the process jumps to step S510.
Specifically, the computer device obtains a state value of the service data information at the service node, then compares the state value with a state value corresponding to the service node, and if the state value does not match with the state value, determines that the data state of the service data information is abnormal.
In this embodiment, the status value of the service node, for example, for the loan service, may be considered as the payment date and the payment amount. The computer device monitors the service data information including repayment date and repayment amount by acquiring repayment records of the first financial institution about the client for the loan service; and then, the computer equipment compares the repayment date and the repayment amount in the service data information with the repayment date and the repayment amount of the service node state value, and when the repayment date in the service data information is later than the repayment date of the service node state value or the repayment amount in the service data information is smaller than the repayment amount of the service node state value, the data state of the loan service information is judged to be abnormal.
And step S508, transferring the customer information to a preset customer information blacklist and adjusting the integrity value of the second alliance member according to a preset integrity value calculation rule. And the coalition members with the integrity value lower than the preset threshold limit the authority of uploading data.
Step S510, distributing the profits of the service data information to the first alliance member and the second alliance member respectively according to a preset distribution rule.
In this embodiment, the allocation rule includes: assigning a first percentage of the profit for the business data information to the first coalition member and a second percentage of the profit for the business data information to the first coalition member. The integrity value calculation rule is as follows: and the ratio of the number of the client information obtained by subtracting the number of the client information transferred to the client information black list from the client information white list uploaded by the coalition members to the total number of the client information white list is multiplied by 100. The distribution rule and the integrity value calculation rule are stored in the intelligent contract mode of the block chain through writing, and are stored in the block chain network to be used for standardizing data operation behaviors on the block chain.
In this embodiment, when the user white list uploaded by the second financial institution is not of good quality, then the other financial institutions may cause frequent loss of trust after performing loan transaction according to the customer data of the customer information white list corresponding to the second financial institution. In this case, for example, the computer device monitors that the data state of the loan transaction information of the first financial institution is abnormal. The computer device transfers the customer information from the customer information white list corresponding to the second financial institution to a preset customer information black list, and then multiplies the ratio of the quantity of the customer information obtained by subtracting the quantity of the customer information transferred to the customer information black list from the customer information white list corresponding to the second financial institution to the total quantity of the customer information white list by 100 to obtain the adjusted integrity value of the second financial institution. And the integrity value is used for adjusting the authority of the second financial institution, such as the authority of uploading authority service data (namely service handling authority). For example, the customer information white list uploaded by the second financial institution includes 100 pieces of customer information, and when the number of users in the customer information white list transferred to the customer information black list is 30, the corresponding integrity value of the second financial institution is (100-30)/100 × 100=70. When the integrity value is smaller than a preset threshold value, such as 80, the computer device performs permission degradation processing on the second financial institution, for example, the computer device presets a financial institution level system, for example, the financial institution level system is divided into 5 levels, each level has 20 integrity values, the 1 level has the lowest 0-20 integrity values, and the 5 levels have the highest 81-100 integrity values. The level is used to evaluate the credit rating of the financial institution, and when the credit rating of a financial institution is poor, for example, below a 4-level 60-loyalty value, the financial institution's total amount of financial transactions to be processed is limited.
Of course, if the computer device monitors that the data status of the loan transaction uploaded by the first financial institution is not abnormal, the profit of the loan transaction is distributed to the first financial institution and the second financial institution according to the preset distribution rule, for example, 80% of the profit is distributed to the first financial institution and 20% of the profit is distributed to the second financial institution.
The block chain-based coalition member management method provided by this embodiment can acquire corresponding client information after receiving service data information uploaded by a first coalition member; then, traversing the client data stored in the block bodies of all the blocks, and searching all the client information white lists comprising the client information; then selecting a first customer information white list with the earliest link entering time, and querying a corresponding second union member; then monitoring the data state of the service data information in a preset service period; and when the data state is abnormal, transferring the client information to a preset client information blacklist and adjusting the integrity value of the second alliance member to adjust the authority. In this way, the state analysis of the business data and/or the client data uploaded by the coalition members is performed, so that the coalition members can be evaluated and managed fairly and effectively.
