AI Tool Shows Promise in Identifying Suspicious Crypto Transactions
Achieving a High Accuracy Rate
Researchers at the Massachusetts Institute of Technology (MIT) and cybersecurity firm Elliptic have developed an AI-powered tool that can identify suspicious cryptocurrency transactions with a high degree of accuracy. To test the tool, the researchers partnered with a cryptocurrency exchange, which they have chosen not to name, and identified 52 suspicious chains of transactions. Notably, the exchange had previously flagged 14 of the same accounts as suspicious, including eight related to money laundering or fraud.
The Power of the AI Model
Despite having no access to know-your-customer data or information about the origin of the funds, the AI model accurately identified the same 14 accounts as suspicious. This achievement is all the more impressive considering that the exchange flags only 0.1% of its accounts as potential money laundering cases. By leveraging the AI model, the researchers claim to have reduced the search for suspicious accounts to over one in four, leading to a significant increase in accuracy.
Mark Weber, a coauthor of the study and a fellow at MIT’s Media Lab, commented, “Going from ‘one in a thousand things we look at are going to be illicit’ to 14 out of 52 is a crazy change. And now the investigators are actually going to look into the remainder of those to see, wait, did we miss something?”
Real-World Applications
Elliptic, the cybersecurity firm involved in the project, has already begun using the AI model in its own work. The researchers highlight the potential benefits of the tool in identifying Bitcoin addresses controlled by a Russian dark-web market, a cryptocurrency “mixer” designed to obscure the trail of bitcoins on the blockchain, and a Panama-based Ponzi scheme.
Elliptic declined to name the alleged criminals or services involved in these cases, citing ongoing investigations. The researchers emphasize the value of their AI model in providing investigators with valuable insights and reducing the need for manual review of transactions.
Open-Source Data Release
Elliptic has released its training data, consisting of anonymized and structural information about “subgraphs” of transactions, on the Kaggle platform. This move towards open-source collaboration has been praised by experts in the field, who see it as an opportunity for competitors to improve their own anti-money laundering (AML) efforts.
Conclusion
The development of this AI-powered tool represents a significant advance in the fight against cryptocurrency-based money laundering. By leveraging machine learning and natural language processing, the researchers have demonstrated the potential for AI to improve AML efforts. While some experts have cautioned that the tool is still in its early stages and may require refinement, the release of open-source data provides an opportunity for further research and development.
