Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment of the application provides a blockchain-based audit data cross-chain interaction method. The execution subject of the blockchain-based audit data cross-chain interaction method includes, but is not limited to, at least one of a server, a terminal, and the like, which can be configured to execute the method provided by the embodiments of the present application. In other words, the blockchain-based audit data cross-chain interaction method may be performed by software or hardware installed in a terminal device or a server device. The service end includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, and the like.
Example 1:
referring to fig. 1, a flowchart of a blockchain-based audit data cross-chain interaction method according to an embodiment of the present invention is shown. In this embodiment, the blockchain-based audit data cross-chain interaction method includes:
s1, extracting auditable block information from a pre-constructed common public chain by using a perception node of the pre-constructed user parallel chain.
The user parallel chain is a user-specific parallel chain, and can be used for transmission and storage of audit data of a user. The sensing node refers to a node for monitoring messages and collecting data in the user parallel chain, the sensing node can realize cross-chain interaction between the user parallel chain and the common shared chain, monitor the transaction or information on the common shared chain, convert the monitored transaction or information into a data format which can be processed by the user parallel chain, and then distribute the processed data to other nodes on the user parallel chain.
It can be understood that the consensus public chain refers to a public chain constructed based on a HashNet consensus mechanism, and the HashNet consensus mechanism adopts randomness and broadcasting to ensure the fairness and non-tamper property of the random weight of each node, so as to realize an efficient, rapid and safe blockchain consensus process.
Further, the auditable block information refers to information of an audit item that can accept an audit, and the audit item can include: a fund rolling budget project, a cash flow project, an asset and liability project, a performance index project, a tax finance project, and the like.
In the embodiment of the present invention, before the perceptual node using the pre-constructed user parallel chain extracts auditable block information from the pre-constructed public chain, the method further includes:
receiving an item audit request by using the relay link of the public chain;
extracting project audit line and audit project from the project audit request, and obtaining the auditable request frequency corresponding to the project audit line;
acquiring the current request frequency of the audit item, and judging whether the current request frequency is greater than or equal to the auditable request frequency;
if the current request frequency is not more than or equal to the auditable request frequency, returning to the step of receiving the project audit request by using the relay link of the common public chain;
if the current request frequency is greater than or equal to the auditable request frequency, auditable block information of the audit item is constructed.
It can be appreciated that the project audit request directs a user parallel chain to send an audit request to a relay chain of the common public chain, including: the amount of each item index in the audit item. For example: when the audit item in the item audit request is a funds rolling budget item, the item index may be: budget execution rate (Budget Implementation Efficiency), funds in place rate, funds execution rate, and individual subject amount variation. The budget execution rate refers to the in-place ratio of the budget funds of the last month, and the budget execution rate is = (actual expenditure funds/actual in-place funds) multiplied by 100%; the funds in place rate refers to the ratio of the funds raised in the last month to the planned raised funds; the rate of funds execution refers to the ratio of paid out funds to budgeted paid out funds, the single subject amount change refers to the amount change of budgeted subjects between this month and the last month, budgeted subjects can actually pay out funds, actually in place funds, budgeted paid out funds, budgeted in place funds, etc.
Further, the project audit line refers to a total amount of the budget department, for example: when the budget subjects are actual expenditure funds (50 ten thousand), actual in-place funds (60 ten thousand), budget expenditure funds (55 ten thousand) and budget in-place funds (55 ten thousand), the project audit limit is 220 ten thousand.
It can be understood that the auditable request frequency refers to the number of times that the parallel chains of the users send project audit requests to the common public chain, and because the audit related data on the parallel chains of the corresponding users are packaged and sent each time the audit requests are sent to the common public chain, the more the auditable request frequency is, the more the data obtained by the common public chain is, and the more accurate the audit on the parallel chains of the users is. Therefore, when the project audit line is larger, more auditable request frequencies are required, so that the audit accuracy is improved. For example: when the project audit limit is 100 ten thousand, the applicable frequency can be 1000 times; when the project audit limit is 200 ten thousand, the applicable frequency can be 2000 times.
It should be appreciated that the auditable block information refers to information about auditable items in the common public chain that reach an auditable request frequency, such as: when the auditable item is a funds rolling budget item, the auditable tile information may include: the information such as the current request frequency, the auditable project name, the project audit limit and the like of the auditable project.
S2, extracting auditable items from the auditable block information, and extracting item audit records of the auditable items in the user parallel chain according to the auditable items.
As can be appreciated, the project audit record refers to a relevant audit record for the auditable project, such as: when the auditable item is a funds rolling budget item, the item audit record may be a corresponding budget execution rate, funds in place rate, funds execution rate, individual subject amount variation, etc. in the user parallel chain.
In the embodiment of the invention, the extracting the project audit record of the auditable project in the user parallel chain according to the auditable project comprises the following steps:
extracting an associated index data set from the user parallel chain according to the auditable item;
acquiring a promise value of each associated index in the associated index data set;
acquiring an audit record ID and a time stamp, and constructing a record signature according to the audit record ID by utilizing a private key of the user parallel chain;
and constructing the project audit record according to the associated index data set, the promise value, the audit record ID, the timestamp and the record signature.
Further, the project audit record is as follows:
Tx＝<ID,Projects,Cmts,TS,sign(ID)>
Where Tx represents the project audit record, ID represents the audit record ID, projects represents the set of associated metrics, cms represents the set of commitment values, TS represents the timestamp, sign (ID) represents the record signature.
It can be understood that the audit record ID is a unique identifier of a project audit request sent by the parallel user chain to the public chain, and the record signature refers to a signature generated by the parallel user chain by using its own private key, and is used for identifying the user identity of the parallel user chain.
And S3, sending the project audit record to a relay chain of the public link by using the sensing node, and performing validity verification on the project audit record by using the relay chain to obtain a legal audit record.
The relay chain of the common public chain can verify the validity of the data information sent by the parallel chain of the user by using a common mechanism, and when the data information is legal, the node broadcasts the received data information to other nodes. This process includes a number of algorithms and mechanisms, such as: workload proof, rights proof, and the like.
And S4, extracting project audit data from the legal audit record, and extracting a comparison audit data set of the auditable project from the public chain according to the project audit data.
Further, the project audit data refers to audit data corresponding to the auditable project. The control audit dataset refers to all audit data in the auditable item relating to the auditable item, such as: when the auditable item is a fund rolling budget item, the item audit data may be a budget execution rate, a fund in-place rate, a fund execution rate, a single subject amount change and the like in the parallel chain of users, and the comparison audit data set may be a set of related item audit data corresponding to the auditable item, which is sent to the common public chain by other parallel chains of users.
In the embodiment of the present invention, the extracting, according to the project audit data, a comparison audit data set of the auditable project in the public chain includes:
acquiring a project audit interval to which the project audit data belongs;
and extracting a comparison audit data set corresponding to the project audit interval in the consensus public chain according to the project audit interval to which the project audit data belongs and auditable projects.
It can be understood that the project audit interval refers to a range interval defined according to the size of the project audit line, and each project audit interval has a corresponding comparison audit data set. For example: when the project audit interval is 100-110 ten thousand, the comparison audit data set is project audit data corresponding to a user parallel chain with all project audit lines between 100-110 ten thousand in the common public chain.
S5, calculating a difference variation value of the project audit data and the comparison audit data set.
Further, the variance value refers to a variance value of the project audit data from the control audit data set. The larger the variance value of the variance is, the larger the variance between the project audit data and the control audit data set is, which indicates that the project audit data is abnormal.
In the embodiment of the present invention, the calculating a variance value of the difference between the project audit data and the control audit data set includes:
sequentially extracting to-be-examined items and index data sets corresponding to the to-be-examined items from the item audit data;
sequentially extracting the comparison audit items corresponding to the to-be-audited items from the comparison audit data set, and extracting the index data set corresponding to the comparison audit items;
and calculating the difference variation value by utilizing a pre-constructed difference variation value calculation formula according to the index data set corresponding to the project to be checked and the index data set corresponding to the comparison audit project.
In the embodiment of the present invention, the difference variation value calculation formula is as follows:
wherein D represents a variance of difference, n 1 Indicating the total number of item indexes in the auditable item, i indicating the index number, k of the item index in the auditable item i Weights, s, representing the index of the ith item in auditable items i Index data representing an ith item index of auditable items in the item audit data, S i Represent a control trialAnd counting index data corresponding to the ith item index in the data set.
In an interpretable manner, when the auditable item is a funds scrolling budget item, the item index may be: budget execution rate, funds in place rate, funds execution rate, and individual subject amount variation.
S6, judging whether the difference variation value is larger than a preset difference variation threshold value.
The difference change threshold value is the maximum allowable value of the difference change value, and each item audit line has a corresponding difference change threshold value, and the larger the item audit line is, the smaller the difference change threshold value is, the larger the item audit line is, the greater the importance of audit is indicated, so that the limit of audit is higher.
In the embodiment of the present invention, before the determining whether the variance variation value is greater than a preset variance variation threshold, the method further includes:
defining a project audit line interval set, and constructing a difference change threshold corresponding to each project audit line interval in the project audit line interval set;
And constructing a difference change threshold comparison table according to the difference change threshold corresponding to the project audit limit interval.
The difference change threshold value comparison can be explained to be a comparison table constructed according to the corresponding relation between the project audit limit interval and the difference change threshold value.
And if the difference variation value is not greater than the difference variation threshold, executing S7, constructing an audit normal record, and sending the audit normal record to a fusion node of the user parallel chain to obtain an audit normal result.
And when the difference variation value is not greater than the difference variation threshold value, generating an audit normal result through audit.
And if the difference variation value is larger than the difference variation threshold, executing S8, constructing an audit abnormal record, sending the audit abnormal record to the fusion node of the user parallel chain, constructing early warning information by utilizing the fusion node of the user parallel chain, and completing cross-chain interaction of audit data based on a block chain.
In the embodiment of the present invention, the construction of the early warning information by using the fusion node of the user parallel chain includes:
acquiring a difference variation interval to which the difference variation value belongs;
Inquiring the early warning level in a pre-constructed intelligent contract by utilizing the difference variation interval;
and constructing the early warning information according to the early warning level and the difference variation value.
Further, the audit anomaly record refers to information such as a difference change value, a difference change threshold value, an auditable project, a project audit record and the like.
It can be explained that, when the difference variation value is larger, the abnormal situation of the user parallel chain is more serious, so that different difference variation values should correspond to different early warning levels.
Compared with the background art, the method comprises the following steps: the method mainly comprises the steps of calculating a difference change value of an existing comparison audit data set and an item audit record in a user parallel chain by using a block chain, determining an audit result of the auditable item in the user parallel chain according to the difference change value, firstly judging the auditable item, so that auditable block information can be extracted from the common public chain by using a perception node of the user parallel chain, then extracting the auditable item from the auditable block information, after the auditable item is obtained, extracting an item audit record of the auditable item from the user parallel chain according to the auditable item, when the item audit record passes legal verification, extracting the comparison audit data set of the auditable item from the common public chain according to the item audit data, then calculating the difference change value of the item data and the comparison audit data set, creating a result by judging whether the change value is larger than a preset difference threshold value, constructing an audit chain according to the difference change value is not larger than the preset difference change threshold value, and completing interaction and constructing the audit chain based on the difference record of the difference threshold value.
