Description

Intelligent transaction risk analysis and real-time monitoring platform based on block chain

Technical Field

The invention belongs to the field of network payment, and particularly relates to an intelligent transaction risk analysis and real-time monitoring platform based on a block chain.

Background

With the development of network transaction technology, phishing is also aroused, a variety of fraud means are established, fraudsters send remittance to the bank account of criminals through transfer accounts for reasons of 'paying medical fees, financial investment, paying by swiping bills, paying by winning a prize in a prize, canceling network loan' and the like, and the risk of network transaction is greatly increased due to network fraud, so that people need to enhance the judgment of transaction risk during transaction.

A chinese patent with publication number CN113469701A discloses a method for analyzing block chain asset transaction risk, which comprises an illegal asset control wallet address acquisition module, a block chain asset transaction risk studying and judging module, and an illegal asset transfer link monitoring module; constructing an abnormal digital wallet database through a text crawler program; extracting the characteristics of the digital wallets of both parties of the abnormal transaction, such as the historical transaction times, the historical transaction time, the historical transaction amount and the like, and monitoring the asset transfer behavior of the illegal asset control wallet address in real time by depending on the abnormal digital wallet database; the problem of unsafe asset transaction can be solved.

The above-mentioned methods for analyzing risk of block-chain asset transaction still have some problems, and fraudsters generally open accounts and handle bank cards by falsifying the identities of others, so that after the victims find cheats and give alarms, the locking pursuit of criminals is difficult, and in addition, in order to avoid the impoverishment of the fraudulent property, the fraudulent person will generally take out the deposit of the account immediately, in order to be not directly discovered by police, fraud molecules also adopt a manner of hiring people to collect money, many fraud molecules adopt a manner of small amount and large batch fraud, the amount of fraud of a single victim is small, and direct case setting is difficult, when the police receives a large number of alarms and meets the condition of a plan, a considerable number of victims exist, therefore, how to effectively judge whether the transaction object is a fraud or not in time during the transaction becomes very important, and the method for analyzing the block chain asset transaction risk does not effectively solve the problem.

Therefore, the invention provides an intelligent transaction risk analysis and real-time monitoring platform based on a block chain.

Disclosure of Invention

To remedy the deficiencies of the prior art, at least one of the technical problems set forth in the background is addressed.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to an intelligent transaction risk analysis and real-time monitoring platform based on a block chain, which comprises an account information module, a transaction module, a monitoring module, a user behavior module, a data analysis module and an early warning module, wherein the transaction module is used for carrying out transaction processing on a transaction data;

the account information module is used for acquiring and storing account data in the platform; the account data comprises account opening person information, account opening time and account credit level;

the transaction module is used for performing remittance and collection operations between two accounts, and the accounts generate transaction information after finishing transactions;

the monitoring module is used for monitoring and storing the transaction information of the account in real time to form historical transaction data and sending the historical transaction data of the account to the data analysis module;

the user behavior module is used for collecting and storing remittance and withdrawal information of an account, collecting information of a payee at the same time, forming historical withdrawal data and sending the historical withdrawal data of the account to the data analysis module;

the data analysis module is used for analyzing historical transaction data and historical withdrawal data of the account, checking the identity of a withdrawal person through a block chain network and performing credit rating division on the account; the logic for the data analysis module to classify the credit rating of the account is as follows:

when the collection account is a new account and no transaction record is temporarily stored, the credit level of the collection account is the lowest;

after the account carries out normal transaction for a long time, the credit level of the account gradually rises, and the normal transaction comprises collection and remittance;

when the newly opened account only has collection and withdrawal records in a short time, the characteristics of the fraud account are met, and the credit level of the account is reduced;

when a plurality of withdrawers withdraw money from the same account, the withdrawer information of the account is different and accords with the characteristics of a fraud account, and the credit rating of the account is reduced;

the newly opened account receives more remittance in a short time and transfers the deposit to a plurality of new accounts, and the action accords with the characteristics of fraud accounts, so that the credit level of the account is reduced;

the account with the lower credit grade is a fraud account with higher probability and is judged as a risk account;

the early warning module is used for sending out warning to the remittance account. When the credit level of the account is lower, the account is a risk account, and when other accounts send money to the risk account, the early warning module gives out a warning to the money sending account to prompt a remitter to prevent fraud, so that the transaction risk is reduced.
