System for realizing integral accounting by using blockchain technology

Abstract

The invention discloses a system for realizing point accounting by using a blockchain technology. The system comprises an identity recognition module, a node screening module, a bill recognition module and an access analysis module, the identity recognition module is used for recognizing the identity of a login terminal user; the bill recognition module is used for recognizing the uploaded bill voucher; and the node screening module selects a blockchain access node matched with the login terminal according to a preset rule. According to the invention, the blockchain technology is utilized to reduce the transaction behavior that two transaction parties falsify in the accounting process, a service quality score of a blockchain node is calculated by acquiring the state parameter value and theload value of the blockchain node, and a corresponding blockchain service node is selected according to the service quality score; the bill recognition accuracy and efficiency in the blockchain system are realized through the bill recognition module; and the user identity recognition mode adopts a real-time verification code and a random number plus salt strategy to obtain a security code, so that the security of user identity recognition is greatly improved.

Description

technical field [0001] The invention belongs to the application field of block chain, relates to a point bookkeeping system, in particular to a system for realizing point bookkeeping by utilizing block chain technology. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. [0003] In the existing technology, both parties to the same transaction conducted by the buyer and the seller keep their own accounts, which leads to the possibility of fraud in the middle, such as false invoicing, over-recording of expenses, and tampering of transaction i...

Problems solved by technology

[0003] In the existing technology, both parties to the same transaction conducted by the buyer and the seller keep their own accounts, which leads to the possibility of fraud in the middle, such as false invoicing, over-recording of expenses, and tampering of transaction items and amounts during bookkeeping; at the same time, the current blockchain There are also certain disadvantages in the point bookkeeping system. During point bookkeeping, it is impossible to effectively identify the identity of the user who logs in to the blockchain system, and it is also impossible to select a matching and good blockchain service node. Blockchain technology cannot identify all kinds of bills and vouchers well; therefore, we propose a system that uses blockchain technology to realize point bookkeeping
