Recently, criminals have taken advantage of some ordinary people’s lack of understanding of digital renminbi and their desire to actively participate in it. Under the banner of "digital renminbi", they continue to use innovative tricks to defraud, causing property losses and information leakage.
Facing the new situation, on the basis of increasing anti-fraud publicity to the public, what should financial institutions, as important participants in digital renminbi, do in this anti-fraud and anti-money laundering battle?
New topics in security and risk control
“In response to the new topic of digital renminbi fraud risks, commercial banks and payment institutions need to upgrade account front-end identification and verification, merchant information due diligence and transactions Terminal security certification, and then improve the monitoring of abnormal fund transactions, especially the real-time screening rules and early warning models for abnormal digital RMB transactions, strengthen account and merchant management and other technical means, achieve accurate perception and dynamic defense, block suspicious transactions, and cut off problematic transactions. Funding link. "Yue Wei, a security expert in the Tongdun Technology Industry and an anti-fraud lecturer at the Payment and Clearing Association, suggested that commercial banks and payment institutions should focus on the following things:
2. Further strengthen the monitoring of suspicious fund transactions, and set up intelligent real-time and quasi-real-time detection systems to effectively improve the ability to accurately identify risks for abnormal fund flows involving money laundering, such as abnormal signing of digital renminbi, card binding, and recharge, as well as the characteristics of abnormal transactions. .
Three. Comprehensively investigate and identify digital RMB related transactions and related counterparty capital accounts, and promptly cut off the transaction fund payment link. In view of the characteristics of high frequency of digital currency transactions, multiple accounts, and scattered transactions, knowledge graph technology can be introduced to conduct traceability analysis, correlation analysis, and series and merger case analysis to further explore the gangs involved.
“Fundamentally speaking, financial institutions need to address the new risks and new characteristics presented by digital RMB transactions, strengthen their real-time management and control capabilities for abnormal capital chains, improve the anti-fraud system for digital RMB transactions, and understand from the early stage From customer and risk identification to transaction control, cutting off the chain of fraudulent transactions, and then to post-event risk rating and adjusting feedback strategies,” Nian Wei said.
KYC Trusted System
According to Weibo, recent digital RMB fraud schemes mainly involve defrauding and stealing victims’ personal information, stealing and stealing users’ digital wallets and bank accounts. It does not rule out illegal activities such as renting or purchasing other people's mobile phone cards, bank cards/accounts, and digital RMB wallet accounts. In the process of illegal fund transfer through digital RMB wallets, there are often large amounts of small-amount funds flowing across banks, which greatly increases the difficulty for banks to identify transaction accounts.
In addition, financial institutions can also analyze the characteristics of the cards involved, recharge accounts, basic personal information, related party information, internal and external label information and equipment, mobile phone numbers, IP risk lists, etc. Based on the currency-related transaction data it has mastered, combined with external data, it can effectively identify currency-related accounts; and whether trading users conduct risk profiles such as daily trading behavior, commonly used equipment, trusted environment and time based on their accounts, and use machine learning models to Make credible judgments to identify whether users have misappropriated or unintentional transactions.
Monitor currency-related transactions in digital wallets
Based on its dual offline payment, new technology encryption to ensure security and controllable anonymity, the RMB’s legal currency itself has strong Security technology support. The risk prevention of its carrier digital wallet and bank account has become the most important risk prevention and control of this new technology hotspot.
Therefore, the security management of digital RMB wallets, inter-bank fund transfers between digital RMB wallets, inter-bank fund transfers between digital RMB wallets and accounts, etc. all require financial institutions to conduct more targeted Feature capture and abnormal transaction monitoring, identification of abnormal and suspicious transactions through rules and policies, and transaction monitoring between digital RMB wallets and accounts
Financial institutions should implement effective KYC, trusted systems and digital wallet currency On the basis of relevant transaction monitoring, through the data supply of big data platforms and risk control marts, a decision-making system such as currency-related feature calculations, currency-related rules, models and graph analysis is constructed, and finally a list of digital currency transaction accounts/merchant is generated to cut off the involved In the capital transaction link, risk disposal and effect analysis are completed, and feedback is given for the optimization of risk control strategies.
Financial institutions also need to combine the characteristics of illegal fund transfer transactions and focus on monitoring suspicious "collection accounts", because in many problematic transactions, the transfer or payee often changes the "socks" account Or false recharge, payment transactions, etc. to avoid bank risk controls. Therefore, banks and payment institutions need to further establish a database of illegal fund transfer transaction risk lists and implement "zero tolerance" for illegal transaction accounts.
Introduce knowledge graph technology, follow the graph, and strengthen capital chain traceability.
Many money-related fraudulent financial transactions are gang behaviors, with a clear division of labor between upstream and downstream. Financial institutions need to guard against digital renminbi fraud by online gambling, money laundering and other gangs. Therefore, Yuewei recommends that financial institutions use knowledge graph technology to conduct in-depth mining of gang crimes, traceability analysis, and analysis of money-related upstream and downstream account correlations and other gang detection.
Knowledge graphs can help financial institutions build complex entity networks based on data analysis and scenario analysis, and use abnormal relationships and risk characteristic models in knowledge graphs to dynamically calculate risk propagation paths, propagation results and impacts. factors to effectively explore the potential risks of digital currency transactions.
Introducing the risk awareness system
In addition to paying attention to the connection between digital currency, wallets and financial systems and taking measures such as "stop payment", financial institutions can also proactively learn and identify Unknown anomalous events to sniff out potentially risky fraud patterns in currency-related transactions. The terminal security risk situation awareness system is based on device fingerprint technology and network data, combined with big data processing technology, business knowledge accumulation and AI algorithm models, and can proactively target new risk sources that threaten existing systems and information, and achieve proactive risk awareness across the entire network. A fully closed-loop link of detection, defense, visualization, linkage, and traceability.
Currently, the RMB is still in the early pilot stage, and the ecological defense system is still in the process of improvement. Tongdun Technology stated that it will continue to explore and research and continue to provide financial institutions with more complete financial business security solutions.
