Description
Technical Field
The invention relates to the technical field of block chains, in particular to a medical data real-time auditing system and method based on a block chain.
Background
In the prior art, a block chain technology is based on distributed network storage, and by using an asymmetric cryptography algorithm and a consensus algorithm, data can be shared safely and reliably through consensus of a plurality of nodes. And all data sharing processes are public and credible, and data can be traced to the source and cannot be tampered. In addition, through the intelligent contract supported by the block chain, an automatic audit program can be developed, the processes of creating, initially reviewing, rechecking and finally reviewing of an audit project are completed by calling the intelligent contract, and the manual participation degree and the audit cost are reduced by combining big data and artificial intelligence.
The edge computing technology is a technology for solving the problems of high delay, low bandwidth and instability of an access system by providing information services such as computing, storage and the like for an audit unit at the edge of an access network. The edge computing nodes constructed by using the edge computing technology can present a distributed state on physical deployment, only necessary capability modules need to be deployed, and the purpose can be more specialized.
In the prior art, medical audit work plays a significant role in actively promoting the construction of a national medical insurance system, guaranteeing all the diseases of people, and the like. Because the medical audit process is long, the links are multiple, the range is wide, the condition is complex, the traditional manual audit method is long in time consumption and low in efficiency, and the service condition of the medical insurance fund can be audited with high quality and high efficiency only by means of modern information technology.
The current medical audit work is mainly post audit, namely after the medical service work of the audited medical unit is finished, the medical data within a certain time period is submitted to the audit unit, and the audit unit organizes manual audit work. This lag in audit time can lead to late medical violation findings, which can only be followed up afterwards. In addition, submitted medical data usually needs to be processed before auditing, the possibility that the original data is tampered exists, and an auditing unit has difficulty in verifying the integrity of the original data. Meanwhile, a medical professional knowledge base and audit rules according to medical audit are established by multiple parties and have certain differences in various places, for example, medical prescription scheme audit rules are established by the national medical care bureau, and medicine scheme audit rules are determined by standards of medicine administration and price bureau in various places. In the current manual auditing process, due to the difference of medical insurance supervision rules of various regions, the rules used for auditing are easily inconsistent with the rules specified by a supervision organization, and the accuracy and authority of auditing results are affected.

In combination with the above processes, the method process of the present invention can be shown in fig. 3, and the specific process is as follows:
the user of the system comprises an audited unit (medical data provider), an auditing unit and an auditing rule making unit. The system adopts an authentication access mode, an audit administration unit uniformly issues an access account, and only an authorized user can access and check system data. The main operating modes are as follows:
the initial configuration process:
when a new audit service is to be developed, the following work needs to be completed first:
and (3) running an audit block chain platform: an audit administration unit needs to start an alliance block chain through an audit block chain platform node management system to ensure that an account management module, a data sharing interface and an intelligent contract management module run normally;
operating an audit management system: all units participating in auditing, including an auditing rule making unit, need to install an auditing management system, obtain a management account at an auditing administrative unit, and interface the auditing management system with an auditing block chain platform;
configuring an audit edge computing node: the audited unit needs to access the unit data system to the audit edge calculation node, and obtains an account at the audit administration unit to ensure that the audit block chain platform can be accessed;
configuring an audit rule: the medical professional knowledge base on which the medical audit is based, such as data of three categories of social medical insurance (basic medical insurance medicine category, diagnosis and treatment item category and medical service facility category), such as medical categories and audit rules, can be updated by calling an audit rule intelligent contract through an audit management system by an audit rule making unit. And when the intelligent contract on the audit block chain receives the updating request, automatically triggering an updating event. The audit edge node and the audit management system monitor the update event on the audit block chain platform and download the updated data and rules to the local for use and viewing through the data sharing module.
And (3) real-time auditing process:
creation and execution of audit projects: after creating an audit project, an audit unit needs to select a used audit rule and designate the audited unit and corresponding audit responsible personnel. The auditing responsible personnel establish a new auditing intelligent contract on an auditing block chain through a management tool and establish auditing parameters such as audited units, auditing time periods and auditing frequency. And after the audit intelligent contract is established, sending an audit request to an audit edge node of an audited unit. After the auditing edge node of the audited unit monitors the auditing request, the local intelligent medical auditing model is operated by confirming the digital signature, and the intelligent auditing is carried out on the input data according to the required rules and parameters. After the intelligent audit is completed, the audit edge node automatically generates an audit report and data fingerprints of the data, and sends the audit report and the data fingerprints to the block chain by calling an audit intelligent contract. The audit data can not be sent out from the audited unit, and the safety of the original data is ensured.
Auditing initial examination and rechecking: the audit management system can monitor the update event on the audit block chain, and after the audit edge node sends the intelligent audit result, the audit management system can automatically remind the audit responsible personnel to perform initial audit on the result. If the person in charge finds a problem, the person in charge can call an intelligent contract on the blockchain to send a rechecking requirement to the audited unit. After receiving the rechecking requirement, the audited unit can locally complete the complaint report through the audit data management system on the audit edge node and call the intelligent contract to complaint. And after receiving the complaint report, the audit responsible person can check the audit result again and complete the audit report. The auditing responsible person and the auditing unit can have multiple interactions, all can be called and finished through intelligent contracts on the block chain, and the process is public and transparent and cannot be tampered.
And (4) confirming an audit result: and after the audit leader finishes auditing the audit project, submitting a final audit result through the audit management system. The final audit report can be confirmed by the audit unit and the audit department in a digital signature mode, and the multi-party authentication and the falsification prevention of the final audit result are ensured.
And (4) checking an audit result:
when the audit result needs to be checked, the audit responsible person, the audit original data evidence and the chain record of the audit process can be obtained according to the intelligent contract address of the audit project on the chain. The integrity and non-tampering of the audit process and resulting data is verified by the digital fingerprinting of the timestamp and data of the stored records by multiple parties on the blockchain.
In addition, it should be noted that, in the embodiments described in the present specification, the expression of the functional function in the program, the name of the function, and the like may be different.
