Audit data evidence traceability system based on block chain

Abstract

The invention relates to an audit data evidence traceability system based on a block chain. The system comprises a data middle table, a block chain core layer module, an audit service logic layer module and a block chain audit service interface layer module, wherein the data middle table communicates with the block chain core layer module, and the data middle table is used for storing and sharing initial data; the data middle table is also used for encoding and normalizing the initial data, and uploading the processed data to the block chain core layer module; the block chain core layer module communicates with the audit service logic layer module through the block chain audit service interface layer module; the block chain core layer module is used for transmitting the chained data to the audit service logic layer module through the block chain audit service interface layer module; and the audit service logic layer module generates audit result data according to the uplink data. According to the method, decentralized management and whole-course traceability of the data are realized, and the credibility and application security of application data of the audit model are improved.

Description

technical field [0001] The invention relates to the field of audit data storage and traceability, in particular to a blockchain-based audit data storage and traceability system. Background technique [0002] Power grid enterprise engineering project audit is an important means of supervision and management, which runs through the entire project construction. From the audit content of power grid engineering projects, it can be seen that there are many audit objects, long audit cycles, complex professional fields, gray areas, etc. are general project audits incomparable. However, relying solely on manpower to carry out audit work cannot achieve effective implementation, and the construction of audit informatization for power grid enterprise engineering projects is imperative. [0003] Judging from the current auditing status of power grid projects, there are common problems in China's power grid enterprise engineering projects: the use of funds and project progress during the...

AI Technical Summary

Problems solved by technology

Subjectively, auditors are resistant to repeated on-site inspections, but objectively, auditors cannot monitor all construction activities with manpower alone; the timeliness of auditing after completion is poor

Theoretically, the final account preparation and audit should be carried out immediately after the power grid project is delivered, but in fact, the construction party usually only exposes the bad situation a few years after the completion of the project, thus missing the opportunity for audit and investigation

[0004] That is to say, the current audit application can only see the result data of doubtful points, it is difficult to understand the situation and quality of the analysis supporting data of doubtful point problem data, and it is impossible to realize the traceability of audit data
