To further explain the present solution, the present application further provides a specific application example of implementing the blockchain transaction auditing method by using the above blockchain transaction auditing apparatus, and refer to fig. 3, fig. 4 and fig. 5, which specifically includes the following contents:
1. financial transaction audit preparation phase
And incorporating the audited unit into the blockchain network environment to serve as a transaction node, and uploading various related information to the blockchain technology platform by using a data transmission channel. By knowing the external environment, such as the industry condition, the supervision environment, the internal factors, such as the property of the unit, the selected accounting policy, the internal control system and the like, of the audited unit, the acquired information is subjected to supplementary recording, the data of production and operation activities, such as purchasing, selling and other links of the audited unit is authenticated by utilizing the timestamp function of the block chain, and fixed assets, intangible assets and the like listed by the account can be verified by means of the function. In addition, audit work can be carried out while transaction data are generated, an audit plan does not need to be made in advance, and unnecessary cost waste is avoided.
2. Assessment of internal management system of financial transaction
It can be understood that if the internal management system of the transaction node (and the audited unit) is relatively sound, the probability of illegal violation of the audited unit or fraud of internal personnel is relatively low. Therefore, before the audit process enters the audit implementation stage, an auditor needs to comprehensively evaluate an internal management system or an internal control mechanism of an audited unit, identify the major risk of the internal system, perform key monitoring aiming at the major risk, and record the relevant system of an enterprise into an intelligent contract library in a block chain. (the system is an enterprise system, and different systems can be recorded into an intelligent contract library in a block chain according to different enterprise systems)
The main reasons include:
first, because of the large number of financial institutions, the nature division of each financial institution is not very clear, and the internal system of the enterprise is very different.
Secondly, the audited unit usually has business exchange with other business units, and the internal system is more various and can only be determined according to different enterprise system conditions.
3. Financial transaction auditing implementing stage based on block chain technology
When a financial transaction service occurs at a transaction node, namely a transaction information block is newly added and linked, the blockchain application platform can prove the authenticity of the service with other transaction nodes (such as an upstream supplier of an audit client, a downstream client, a service forward bank and other related parties) through an external network in real time, and stores real transaction data by using a blockchain technology; and carrying out all-around examination on each financial transaction service, drawing a fund flow direction table according to financial transaction facts, and tracking fund flow direction.
Optionally, the application further sets an audit early warning model, and analyzes and predicts a relevant model of financial transaction economic activities that have occurred by using transaction data stored in the system, which is specifically shown in fig. 4:
1) the user interaction module is used for applying for inquiry interaction by an audit user, and the user configuration module is used for automatically matching a user request after the audit user applies for audit inquiry; before financial auditing is implemented, business data generated by audited units and business data generated from and to audited units are all included in a block chain system, and the record and update of each data are synchronously included in the whole block chain. And the financial auditing staff logs in the user interaction module by virtue of the corresponding authorization secret key, and meanwhile, the user can carry out user habit configuration according to the authority and has the authority to inquire financial auditing data information on the whole block chain.
2) An auditing user calls an intelligent contract through a user interaction module, the intelligent contract calls a block chain interaction module to perform data calling with a block chain system, namely, the auditing user performs transaction data check according to a relevant system in an intelligent contract library, if suspicious data exist, the intelligent contract gives corresponding early warning labels for the intelligent contract, and the auditing user performs further auditing according to the early warning labels.
3) The intelligent contract calls financial transaction data on the blockchain and confirms whether certain data in the financial audit blockchain database is normal or not. If the result is normal, forming a new block to be uploaded to the block chain, automatically defaulting the new block to be a real account book by the system, and recording related information; if the data is abnormal, the block chain system informs the financial auditor of the abnormal data.
4) The financial auditor confirms whether the data is authentic. If true, the method is the same as the previous step; if not, checking whether more relevant data can be obtained in the financial audit block chain database.
5) To see if more audit data can be obtained. If the data can be obtained, returning to the previous step, namely confirming the authenticity of the data; if the business is not obtained, the business is judged to be invalid, the block chain system is defaulted to be a false account book and is simultaneously fed back to the risk assessment program, and the financial auditor can implement the risk assessment program again.
4. Audit reporting phase
Under the block chain environment, real-time monitoring is carried out on audit clients through a block chain application platform, and an audit result is continuously obtained for each transaction service; the related interest parties can check the current audit report and audit opinions anytime and anywhere as long as the related interest parties have the management authority. The auditor should also arrange all audit evidence, accounting data, audit doubtful point inquiry letter and other data according to the regulation of the related audit criteria, and form electronic storage of audit data.
Referring to fig. 5, specifically:
(1) and collecting related videos and images through a video and image collecting module.
(2) The judgment module judges whether the video and the image have violation conditions.
(3) And the analysis module is used for carrying out video and image violation reasons and positioning the responsible person.
(4) The storage module stores the related results of each process of video and image acquisition, judgment, analysis and the like.
Under the block chain environment, an intelligent auditor can automatically analyze the data model and record the auditing result in real time, and auditors can utilize the block chain platform to monitor audited units in real time and issue personalized customized auditing reports according to the requirements of customers at any time so as to meet the main requirements of different stages.
As can be seen from the above, the present application can achieve at least the following technical effects:
1. the data acquisition effectiveness is improved, the transaction data is stored in the block chain, and the problem of real-time data acquisition and storage is solved, so that the problems of data loss, data loss and data errors in the process of manually acquiring the data are solved. And the safety of data storage is ensured, and the requirement of the state on the electronic storage of the accounting information is met.
2. The auditing timeliness is improved, the block chain real-time auditing plays a technical role, the problem of the traditional on-site auditing time lag is solved, and the irreparable loss of an audited unit caused by strategy decision errors or poor operation management is prevented through an auditing early warning mechanism in a real-time auditing application platform.
3. The method can assist decision-making, and currently, computer-aided audit software can only realize inquiry, screening and filtering on some transaction data, but cannot systematically assist decision-making on the transaction data.
