Introduction

In 2023, alone, consumers lost a record $10 billion to financial fraud. With bad actors resorting to several advanced and sophisticated fraud mechanisms, companies across the banking, investment, insurance, and accounting sectors suffer the consequences. While many have resorted to rules-based fraud detection techniques, they fail to keep up with the pace of advanced mechanisms that hackers use today.

Introduction to Rules-based Fraud Detection Models

Financial fraud has extremely far-reaching implications for businesses and individuals alike. While it leads to direct monetary losses, it also erodes customer trust while causing substantial reputational damage. Financial fraud can also disrupt market dynamics and create unnecessary volatility and uncertainty.

Rules-based fraud detection models have long been employed by organizations. Operating on a pre-defined set of rules or conditions, they help discover potentially fraudulent transactions. For instance, they might alert teams if transactions take place from an uncommon location, from an unknown device, or more frequently than usual.

However, in an age where hackers are embracing innovations in AI to carry out fraud, traditional rules-based models can no longer be deployed by organizations. These static models:

  • Have limited scalability and cannot be expanded to cater to a large number of users or fraud types and techniques.
  • Support restricted use cases with limited complexity since rules have already been defined and fed into the models.
  • Demand substantial manual effort in defining and updating rules and constantly inputting data from multiple data sources.

Integrating Rules-Based Models with AI for Fraud Prevention

In an ever-changing landscape with evolving customer expectations, integrating rules-based fraud detection models with AI opens doors to scalable and accurate detection techniques. Artificial Intelligence helps address the shortcomings of traditional rules-based systems. They deliver several benefits in environments where the volume and dimensionality of data are high, and the variety and diversity of fraud are constantly growing.

Relying on algorithms like decision trees, neural networks, and deep learning, these rules-based AI models go a step beyond fraud detection. Through proactive interception, they allow organizations to prevent fraud, while paving the way for:

  • Intelligent and automated monitoring to detect complex and nonlinear patterns quickly and accurately across hundreds of transactions.
  • Continuous learning with models constantly learning from the new data that they are fed and flagging transactions with new and unique fraud characteristics.
  • End-to-end security since the models can be trained across hundreds of permutations and combinations of device types, locations, fraud patterns, and more.
  • Transparency and visibility as they rely on algorithms characterized by their simplicity, transparency, and interpretability, ensuring the decision-making process is explicitly expressed in the form of rules.

Scalability as their intelligence grows as more fraud data is fed into them, helping organizations flag even the extremely exceptional cases of fraud.

The Challenges of Implementing These Models

Rules-based fraud detection models, when combined with AI, can completely transform how fraudulent transactions are detected and managed. However, implementing these models comes with its own set of challenges.

  • ​Complex data management: If rules-based AI models need to accurately spot and stop financial fraud, they must be fed with massive amounts of training data. Identifying the right data sources, collecting, and storing this data, and then managing it through its lifecycle is a Herculean task. Ensuring high-quality, labelled historical data is used as training datasets demands the skills and capabilities of experts.
  • Limited expertise: Rules-based AI models, although extremely beneficial for fraud detection and resolution are not easy to build or implement. While out-of-the-box models fail to meet unique use cases, building these models from scratch is a different ball game. In-house data teams that are already burdened with several competing priorities cannot address the challenges that come with the development of rules-based AI models.
  • Lack of roadmap: Organizations that invest in rules-based AI models to combat fraud also need to understand that implementation is not just a one-time activity. These models must be constantly monitored for issues and challenges, the data that is fed into them periodically cleaned and updated, etc. A clear roadmap that defines how and where these models will be used, who is responsible for managing data, how the data will be encrypted, etc., is critical to their long-term success.

Get a Step Ahead of Fraudsters with AI

The financial services industry is undergoing a transformational change, facilitating transactions through new digital channels to remain competitive. While these advancements enable high levels of speed and convenience, they also expand the threat surface for fraudsters.

Traditional, rules-based fraud detection techniques are incapable of catering to modern-day fraud. However, when combined with the innovations in AI, they allow for several benefits. From intelligent and automated detection to seamless scalability, higher transparency and visibility, and more, the ability of rules-based AI models to learn from experience and identify new and uncommon transactions is what makes them truly phenomenal.

In the next part, we will showcase how you can successfully implement these models in your organization with the support of an expert partner and master the art of financial fraud detection and prevention.
