What if you could accurately predict fraud before it even happens? Thanks to the ever-growing field of AI, that's no longer a pipe dream. In fact, AI is already being used by financial institutions to detect patterns in fraudulent behavior and prevent losses.
In a recent study by PYMNTS, 80 percent of fraud prevention experts said AI can reduce the success rate of payments fraud. Moreover, around three-quarters of banks with more than $100 billion in assets have an AI solution in place. This is largely due to the fact that AI can do things like identify inconsistencies in spending behavior and distinguish between human and machine-generated data.
In this article, we’ll explore how machine learning detects and predicts fraud, the impact it can have on a business and how you can get started with implementing AI to your business.
In order to understand how AI can be used for fraud detection, it’s important to first understand what AI is. AI is a field of computing that enables machines to learn and work like humans. This means that they can not only understand and respond to instructions, but can also learn and evolve over time.
One of the key benefits of AI is its ability to process large amounts of data quickly and accurately. This makes it the perfect tool for fraud detection, as financial institutions are constantly collecting data on spending patterns, account activity, and so on.
Fraud can come in many different forms, but typically, it refers to any illegal activity that results in financial gain. This could include activities like credit card fraud, mortgage fraud, or insurance fraud. Credit cards are the most frequent payment method used in online fraud, according to Intuit.
Fraud is a major issue for businesses, as it can lead to lost revenue, higher costs and even criminal charges. In fact, the Association of Certified Fraud Examiners (ACFE) estimates that businesses lose 5% of their revenue to fraud every year. This amounts to $3.5 trillion globally. , and this number is only going to grow as more and more businesses move to digital platforms.
In the early days of ecommerce, payment fraud was not much of a problem. But as online sales have grown, so too has payment fraud. A recent report from digital security firm Help Net Security found that the number of global cyber attacks increased by 50% in the fourth quarter of 2021, compared to the previous quarter. And the number of Russian-hosted attacks jumped by 42%.
In the first three quarters of 2021, over 12.9 million unique compromised cards and card previews were recovered from online stores and fraud communication channels. Beyond the monetary losses, businesses also face significant reputational damage when fraud occurs. In the age of social media, word travels fast and bad publicity can be very costly.
There are several types of payment fraud, but the most common include credit card fraud, check fraud, and wire transfer fraud.
Credit card fraud is the use of a stolen or counterfeit credit card to purchase goods or services. This type of fraud can be very lucrative for thieves, as they can rack up large amounts of debt in a short period of time.
Check fraud is the use of a stolen or counterfeit check to purchase goods or services. This type of fraud is typically less profitable for thieves than credit card fraud, but it can still be very costly for businesses.
Wire transfer fraud is the use of a stolen or counterfeit wire transfer to purchase goods or services. This type of fraud is the most costly for businesses, as it can involve large sums of money.
Historically, businesses that wanted to use the data to prevent fraud have had to rely on armies of data scientists and engineers to build predictive models by hand. The process can be expensive and time-consuming, and the results are often difficult to replicate and maintain.
Akkio has built a business on a different model: using automated machine learning to create predictive models without any code. Rather than hiring data scientists, companies can simply upload their data to the Akkio platform and let the software do its work.
What once took months and millions of dollars can now be done in minutes and for a tiny fraction of the cost. The biggest challenge in effective fraud detection is the sheer number of potential variables to consider, something that Akkio’s platform is designed to handle.
With potentially millions of data points to analyze, businesses need all the help they can get when it comes to spotting fraudulent activity in real-time. Akkio’s no-code approach to machine learning can help them do just that.
Like a needle in a haystack, finding fraudulent transactions in a sea of financial transactions can be a daunting task. But new data-mining techniques are making it easier for companies to detect anomalous behavior that could signal fraud.
One such technique is called "outlier detection" or anomaly detection. Outlier detection looks for transactions that fall outside the normal pattern of activity for a given account or customer. These unusual transactions might be an indication of fraud, and can be used to trigger an investigation.
Outlier detection can be used to identify fraudsters in a number of different ways. For example, a company might look for customers who are making unusually large or small transactions, or who are making multiple transactions in a short period of time. Outlier detection can also be used to identify fraud patterns, or patterns of behavior that are inconsistent with normal buying or selling habits.
By identifying anomalous behavior, companies can reduce the risk of fraud and protect their bottom line. Outlier detection is just one tool in the arsenal of fraud prevention techniques, but it is an important one, and is becoming increasingly more sophisticated with each passing day.
To give a specific example, suppose that you have data regarding transaction sizes, dates, and locations for a given customer. Outlier detection can be used to find transactions that do not conform to the usual pattern. For example, if a customer typically makes small transactions in locations within a general area, an outlier would be a large transaction in a different area. This could be an indication of fraud, and could trigger an investigation.
Another example might be a customer who generally makes large transactions on the first day of the month, but suddenly makes large transactions on the fifteenth. This could be an indication that the customer's account has been compromised and is being used for fraudulent purposes.
These examples risk oversimplification, as AI would be used to scan not just a few data points, but potentially hundreds or even thousands of variables with non-linear interactions.
Suppose that a customer generally makes more online purchases over the weekends, but not if they had already spent a significant amount on weekdays, unless it was close to the end of the month. The non-linearity in this example is that the weekday spending impacts weekend spending to a varying degree based on the proximity to the end of the month. Outlier detection would be able to identify this pattern.
Outlier detection is used to measure how different an observation is from the rest of the data. The definition of "outlier" can vary, but it is typically an observation that is far removed from the rest of the data.
There are a number of ways to detect anomalies in data, each with its own advantages and disadvantages. Some of the most common are density-based anomaly detection, clustering-based anomaly detection, and support vector machine-based anomaly detection.
Density-based anomaly detection detects points in a data set that are not typical of the rest of the data. It does this by calculating the density of points in each region of the data set and comparing the densities to a threshold. If the density of points in a region is higher than the threshold, the points in that region are considered anomalies.
Clustering-based anomaly detection detects anomalies by identifying clusters of points that are not similar to the rest of the data. It does this by comparing the distances between points in each cluster and the distances between points in other clusters. If the distances between points in a cluster are significantly different from the distances between points in other clusters, the points in that cluster are considered anomalies.
Support vector machine-based anomaly detection detects anomalies by identifying points that are different from the rest of the data in terms of their distance from the support vector machine. It does this by creating a model of the data and then comparing new points to the model. If the points are significantly different from the model, they are considered anomalies.
What was once a herculean task for fraud prevention teams is now becoming easier with the help of Akkio's automated machine learning platform.
Akkio's no-code AI fraud detection can combat fraud by automating the process of building predictive models using historical data.
The first step is to connect to the relevant transaction data sources, which can include internal data lakes as well as external data providers, both of which are typically large datasets, containing fraud cases and normal transactions. This training data is then pre-processed and cleaned automatically, so that models can be built on top of it with no intervention.
The next step is to select the column to build the AI model around. The next step is to select the column to build the model around. Akkio’s algorithms get to work, automatically finding the best models for fraud prevention, from big data fueled neural networks, or deep learning, to other machine learning models and ensembles. The models are then tuned and refined until they reach a high level of accuracy.
The final step is to deploy or integrate the model into existing systems. This can be done in minutes, and results in a practically immediate reduction in fraud losses. The model can be deployed directly in any financial system with Akkio’s API, which can classify data points in milliseconds.
Using Akkio's platform, businesses can quickly build models that can identify patterns in data and predict potential instances of fraud. This can help businesses automate the fraud prevention process, reduce false positives, and improve their overall fraud detection rates.
Beyond fraud prevention, AI is being used by business teams across sales and marketing, operations, legal, customer support, and other areas to automate tasks, improve decision making, and provide new insights.
For example, sales teams can use AI applications to automate lead scoring and qualification, predict customer churn, forecast sales, optimize sales funnels, and boost customer LTV. Marketing teams are using AI for tasks such as building customer personas, optimizing content, increasing order value, and classifying text.
Operations teams are using AI for things such as reducing employee attrition and absenteeism and automating legal responses. AI is also being used by customer support teams to automate the identification of customer issues and recommended solutions, as well as to provide predictive analytics on where customers are likely to have problems.
