Harnessing Hybrid AI-Human Models for Enhanced Fraud Detection

With fraud forming part of an increasingly complex cat-and-mouse game, banks and companies alike around the world are adopting such hybrid AI-human models. With its ability to process huge volumes of data at lightning speed, it’s siding artificial intelligence with human expertise for the very first time, a new way of looking at data that is taking the fight to financial crime.

Rule-based fraud detection systems can be effective for known fraud cases but have difficulty keeping up with emerging fraud behaviors. AI and machine learning, by contrast, are great at parsing through huge swaths of data in milliseconds, picking up nuanced abnormalities, and to spot intricate patterns – sometimes invisible to humans – that can be signs of illicit conduct; yet, we can’t just rely on AI alone because it may result in false positive or it may stumble with gray-area, where human intuition is required.

This is where the hybrid comes in. Leaders of the AI movement, such as i2c, see AI not as a replacement for human employees, but rather as the ultimate augmentation tool and a force for “augmented intelligence.”

Their systems consider hundreds of behavioral signals and contextual cues in order to dynamically score each transaction. If the AI’s decision isn’t straightforward, the case is immediately forwarded to a human analyst.

This layered workflow, known as “commonsense intelligence,” says AI will emphasize potential threats and let human experts make the final, well-informed choices.

There are many advantages to this co-operative strategy. It cuts down false positives big-time (reducing friction for good customers and increases discovery of real time fraud). Human analysts also offer valuable input towards helping to hone AI models, allowing them to keep up with new schemes.

This cycle of continuous learning ensures that the detection systems are continually hardened against ever-evolving attacks including those based on generative AI, which can be used to create highly realistic fake content and manipulate identity.

Additionally, the hybrid model mitigates some limitations associated with integrating AI, including but not limited to privacy issues, algorithmic bias, and explainable AI (XAI) through human oversight and ethical considerations.

Through the collaboration of AI and human intelligence, organizations will not only improve their ability to detect fraud, but also create an atmosphere of trust and protection within the digital financial landscape. The future of fraud detection definitely lies here, in this powerful combination.
