AI-Powered Account Behavior Analysis — Major Component in Fighting Deposit Fraud
- AI is making a huge impact on how FIs deal with fraud
- The account holder is now point of focus
- Explainable AI (XAI) is growing in importance
Artificial intelligence (AI) is dramatically altering the way fintech approaches fraud detection, as highlighted in a recent post entitled “The Role of AI in FinTech Fraud Detection” from FinTech Weekly.
With the exponential rise in digital financial services, attackers have become more sophisticated, prompting organizations to seek modern defenses. AI comes to the forefront, deploying intelligent algorithms and machine learning to create resilient, adaptive fraud prevention tools.
These new tools have become increasingly more important, as financial institutions look to strengthen their deposit fraud detection against more globalized mule operations.
Focus on the Account Holder
The article takes a deeper look at the account holder, and the unique characteristics which can be analyzed. Rather than relying on static credentials, behavioral biometrics (a subset of behavioral analytics) tracks the unique behavior of the individual — such as how individuals type, swipe, or navigate interfaces. This makes it tough for fraudsters to replicate legitimate patterns convincingly, minimizes false positives, and strengthens account protection, thereby reducing friction for genuine users while blocking suspicious activity.
The article also emphasizes the capabilities of graph analytics. By constructing and analyzing webs of users, devices, and transaction histories, AI systems can uncover previously hidden relationships and detect patterns that indicate orchestrated attacks. This enables financial organizations to respond faster and more accurately to coordinated fraud attempts—spotting links that manual reviews generally miss.
Geospatial analysis powered by AI further refines fraud detection. The technology continuously compares transaction locations with historical user data, flagging those that deviate from an individual’s usual geographic pattern. When paired with real-time anomaly detection—an area where AI excels—this creates a multi-layered network of defense. AI instantaneously evaluates vast datasets for subtle inconsistencies, identifying emerging threats before they escalate into larger breaches.
Most importantly, the article notes the growing importance of explainable AI (XAI). As regulators demand transparency, XAI ensures each security decision is traceable and accountable, enabling institutions to meet compliance requirements and reassuring consumers about fairness and privacy.
Relating Back to Deposit Fraud
These technologies are also important for check fraud detection, particularly when it comes to check deposit fraud. Behavioral analysis is one of the seven (7) layers of the multi-layered technology approach to check fraud -- serving as another input in understanding and mitigating risks associated with financial transactions by importing indicators and data attributes connected to individual accounts. This approach enables financial institutions to score deposits by utilizing information such as account risk scores and status indicators.
Individual analyzers for behavioral analytics also include deposit location and time. Deposit location has become increasingly important, particularly as stolen checks have become the most prevalent method for obtaining checks. If an account is open in a certain location and a check is deposited at a location across the country (I.e. account opened in Maryland and a check is deposited via ATM in California or a mobile device geolocated in Arizona) or different country, this deposit activity is flagged. Furthermore, the time of the deposit can indicate fraudulent activity, as depositing a check at 2:00AM at an ATM can be seen as suspicious.
As global fraud operations increases, these new technologies supplement existing tools with behavioral insights -- enabling financial institutions to create a more holistic view of account behavior, ultimately leading to better fraud prevention strategies and improved customer trust.
