Using Artificial Intelligence for Fraud Detection

Fraud is a rising problem with severe consequences for the banking sector regarding financial loss and credibility. PwC’s Global Economic Crime & Fraud Survey 2020 found that respondents reported losses of $42 billion in the last 24 months. Worse, 56% of financial institutions surveyed said they had investigated their worst fraud case, and a mere third of respondents reported fraudulent behavior to their boards.

As most transactions are digital, there is an obvious necessity for improved fraud detection systems and robust fraud management systems within banking. The rapid growth of online and digital banking has resulted in an exponential rise in transactions. Fraudsters are more intelligent and more sophisticated, using innovative fraud strategies to avoid being detected.

What does Machine Learning mean for Fraud Detection in Banks?

Machine learning is the science and art of creating algorithms that find improvements based upon previous experience. It analyses considerable amounts of data using complex algorithms to determine patterns. Deep learning allows machines to predict and respond to different situations even though they are not explicitly programmed.

There are many uses for machine learning, including market research, predictive analytics, and product recommendations. However, one of the most critical machine learning applications is detecting fraud. Machine learning is all based on the idea that fraudsters have specific patterns that distinguish them from legitimate ones. These patterns are recognized by machine learning algorithms, which can distinguish between legitimate clients and fraudsters. Because they have access to larger data sets, these algorithms can detect fraud faster than traditional rules-based systems and with greater accuracy.

Machine learning algorithms can recognize patterns in seemingly unrelated data, which can be difficult for humans and programs that follow the rules. All this sounds interesting, right? You can check out the various Great Learning artificial intelligence courses, which can help you understand these concepts in-depth and pave your way for a courses for artificial intelligence successful AIML career path.

Machine Learning is a Tool that Helps Detect Fraud

Machine learning is used to prevent fraud and manage risk. This information includes both legitimate and fraudulent transactions, and it can be labeled as good (legitimate customers or transactions) or bad (fraudulent customers or transactions).

The data is used to “teach” the machine learning program to predict whether a client or transaction is fraudulent. It is vital to have as many fraud patterns as possible so that the algorithm has many examples, which will make this fraud detection system more effective. After the machine learning algorithm has been trained, you can use it in a bank’s fraud management system. It is essential to update the algorithm from time to time as it is not perfect. It does have some benefits but just as a fraud detection tool.

Machine Learning is a Great Tool for Fraud Detection

Modern analytics tools and systems rely heavily on humans to analyze data, detect suspicious transactions, and identify fraudulent activity. This dependency can lead to human error and slow speeds. Some of these problems can be solved by machine learning. Machine learning has many benefits for banks, including:

  • Speed – Machine learning algorithms can quickly evaluate and continuously collect and analyze data in real-time. As e-commerce grows in volume and velocity, speed is becoming more critical.
  • Efficiency – Machine learning algorithms can perform repetitive tasks and detect subtle differences between patterns across a large amount of data. It is crucial to detect fraud much faster than humans can. Algorithms can analyze hundreds of thousands of payments per second, and this is much more work than a team of human analysts can accomplish at the same time. This allows for a reduction in costs and a faster process.
  • Scalability – Banks are facing an increasing number of transactions, which puts more pressure on their systems and analysts to scale. This results in increased costs, time, and accuracy. It’s the exact opposite with machine learning algorithms. The more data you have, the better. As more data is added, the program can detect fraud quickly and accurately.
  • Accuracy – You can train machine learning algorithms to detect patterns among seemingly insignificant data, and these algorithms can detect subtle patterns that are not obvious or easy to spot. This improves fraud detection accuracy, which means fewer frauds will be left undiscovered.

How Can AI Help With Account-Related Frauds?

There are two types of account-related frauds: account takeover and new account fraud.

  • New Account Fraud: Those with fake identities are prohibited from opening new accounts. You can conveniently identify frauds by using the patterns of different device and session indicators.
  • Account Theft: The hackers use another person’s accounts to steal products and services. The session, device, and behavioral biometrics are computed and scored to verify an account and prevent this theft. Hackers can take over accounts by exploiting various technical and social vulnerabilities. Analyzing user behavior patterns and journeys can help identify account takeovers before they cause financial harm.

What About The Future?

Banking scams are causing more fraud losses to banks and customers every year. So, it’s vital than ever that you pay attention to Fraud Risk Management and Anomaly detection. Traditional rules-based fraud detection systems no longer work.

Artificial intelligence and machine learning are faster, more efficient, more accurate than traditional rules-based fraud detection systems, and it also saves a lot of human labor. Machine learning programs are the future for those who want to be competitive and fraud-free, and you should choose the best AI certification course from Great Learning to train yourself in the department. Great Learning is one of the best platforms to help you achieve this goal. 


The use of technologies like machine learning, predictive analytics, and AI is becoming more common in insurance, transforming every aspect of the business. These technologies have the potential to directly reduce fraud leakage in claims areas, which can lead to a strong return on investment. It doesn’t matter if you’re building your analytics or working with a vendor to do so; these components are essential for fraud detection in insurance claims. Hence, using Artificial Intelligence for Fraud Detection proves to be highly beneficial.
