Block chain-based auditing and price-auditing fault data online editing method and system

Abstract

The invention discloses a blockchain-based audit and bidding fault data online editing method and system, and the method comprises the steps: constructing an approval structure topology tree, and enabling a multi-party computing server to distribute a parent computing terminal and an adjacent computing terminal according to the approval structure topology tree; the parent operation terminal calculates a first correlation coefficient, and the adjacent operation terminal calculates a second correlation coefficient; the proxy server sends the first tagging information corresponding to the approval terminal to the sub-chain node for storage; the pricing terminal analyzes and compares the first tagging information to determine an initial tracing node; determining a pre-judgment fault node according to a first fault positioning method; if the determined pre-judgment fault node is an edge child node, re-determining the pre-judgment fault node according to a second fault positioning method; and the pricing terminal corrects the project approval form data according to the fault node table and synchronously updates the sub-chain node data. According to the scheme, safety supervision and online editing of the engineering audit and pricing data are achieved, and the automation and intelligence level of audit and pricing work is improved.

Description

technical field [0001] The invention relates to the technical field of power information security management and control, in particular to a method and system for online editing of audit price review fault data based on blockchain. Background technique [0002] Engineering audit is an independent organization and personnel to check the audited unit's accounting vouchers, accounting books, accounting statements and other related data and assets related to financial revenue and expenditure, and to supervise whether financial revenue and expenditure are true and legal. And effective behavior, after the relevant personnel review, generate a stamped audit audit document, and then implement the supervision responsibility of the relevant personnel. The project audit price is to check the billing details of the audit audit documents according to the staged process of each project, and to control the security of the account audit of each project stage; due to the complex and time-con...

Problems solved by technology

The project price review is to check the bill details of the audit and review documents according to the staged process of each project, and to control the safety of the account review at each project stage; due to the complicated and time-consuming planning of power engineering projects, it is usually necessary to formulate the project in the early stage of project planning The construction schedule and project budget schedule; there are many approval documents involved in the approval stage, and the approval time limit of each document is inconsistent, which makes it difficult to manage a large number of approval documents. There are many difficulties in engineering safety control such as revision

[0003] With the rapid development of information technology, information monitoring in the power industry has been widely used, and more and more paper documents are stored on cloud servers through digital means to facilitate subsequent calls; however, for power engineering projects facing Due to the large construction period span, large number of project nodes, and strict and complicated audit and price review, there is currently no automated audit and price review system and method to solve the difficult problem of audit and price review data security supervision in the power engineering stage.
