How banks can use AI to fight fraud together

Friday 15 November 2024 10:10 CET | Editor: Alin Popa | Voice of the industry

As the battle against payments fraud intensifies, Jackie Barwell of ACI Worldwide stresses the need for banks to unite and leverage AI to tackle risks at their source.

The ever-changing face of payments fraud

Fraudsters are now more equipped than ever to operate on a large scale. Digital and social channels have become new hunting grounds. AI provides ample opportunities for scammers to automate, disguise, and refine their tactics to target vulnerable consumers.

In the UK, card ID theft is wiping out much of the progress made in reducing remote purchase fraud. Fraudsters exploit stolen card details and personal information, readily available on the dark web, to open or take over accounts. Phishing, pharming, and social media scraping are key methods driving the continuous surge in fraudulent activity.

There is also a rise in authorised push payment (APP) scams, particularly those fuelled by social engineering, emails, and fake app or web links. From government impersonations to investment fraud, romance, and delivery scams, criminals are becoming bolder and more creative. In 2023 alone, UK victims reported 252,429 cases of APP scams totalling almost GBP 459.7 million, causing significant financial and emotional harm. 

Looking ahead, the looming threat of deepfake attacks using AI tools for voice and visuals to bypass biometrics or improve credibility in personal scams is likely to fuel even higher-value scams.

Banks can’t afford to stand still in fraud detection  

Not only are fraud incidents increasing in frequency and cost, but banks also face mounting pressure from governments and consumer organisations to address the issue. While fraud and scams often originate online or via telephone, banks are expected to reimburse victims and are under increasing scrutiny to identify recipient accounts for money laundering

The UK is at the forefront of this fight, with new legislation to combat APP fraud taking effect on October 7, 2024. This law mandates shared liability between sending and receiving banks unless a customer is found to have acted fraudulently, or with gross negligence. Similar schemes are being considered globally, with the potential for voluntary collaboration and regulatory mandates. 

While fraud fighters welcome these measures, concerns linger in the banking industry, particularly among smaller fintech companies, about the cost of compliance and potential negative impacts on innovation and competition.

Banks are using AI to reduce risk

Banks face more heavy lifting to prevent sophisticated synthetic fraud and comply with tighter regulations. They must strengthen their safeguards while providing frictionless experiences to retain and attract customers. 

Many merchants are turning to next-generation AI tools to fight back. Machine learning has proven its worth, but it has limitations, especially when dealing with rapid change. Innovations like incremental learning, an ACI-patented machine learning capability, can help address these challenges. Incremental learning maintains and improves model performance. It has been shown to deliver up to a 20% increase in fraud detection rates, according to ACI internal data.

The proposed EU AI Act will require financial institutions to use AI for fraud detection to comply with stringent requirements for data management, security, and human oversight to protect consumer data. 

Fraudsters know no boundaries: banks must avoid silos  

Banks need a way to collectively utilise data responsibly to detect fraud without becoming anti-competitive or breaching customer confidentiality. 

Fraudsters have long exploited banks' siloed nature to commit crimes undetected, taking advantage of the lack of data sharing between institutions. Although there are rules allowing data sharing to prevent crime, banks have historically been cautious, fearing regulatory violations. 

New technology now enables the sharing of derived signals rather than raw data. It is now possible for banks to collaborate by communicating risk-scoring models and indicators of suspicious activity, such as mule accounts or account takeovers, without compromising customer privacy. 

ACI leads the way in cross-bank collaboration  

ACI is at the forefront of enabling this type of cross-bank fraud detection collaboration. Pushing for regulatory changes while leveraging data and technology, our device intelligence and global device fingerprinting capabilities provide risk signals about potential fraud across billions of devices worldwide. 

While technology investment is essential, collaboration is equally vital in combating fraud and scams. As new mandates emerge, banks and intermediaries must work with a partner who understands their specific needs, leveraging AI to optimise operational costs and shifting the heavy lifting.

Democratising intelligence: the role of signals and multilayered AI 

Understanding digital identities is critical to reducing financial losses. Successful fraud management strategies include monitoring customer patterns and profiles to ensure the account attributes match across a comprehensive data consortium and verifying that no synthetic identities or mule accounts have been created.

Monitoring patterns and profiles, ensuring account attributes match across a comprehensive data consortium, and verifying no synthetic identities that could lead to mule accounts or financial losses.

Multilayered, responsible AI tools can provide real-time explainability and understandability, giving users the power to identify fraud efficiently. By sharing signals across institutions and adopting a collaborative approach, banks can outsmart fraudsters and safeguard their customers, ultimately creating a safer financial ecosystem.
