Biometrics, behavioral biometrics, behavioral analytics — while these words may spark visions of a futuristic fantasy movie, biometric technology has been a reality for years. What began in the 1960s with semi-automated facial recognition has evolved into a booming industry that delivers new technologies to fight fraud and improve identity verification across the digital universe. To find the best fraud prevention solution, you need to understand the differences between these options.
As technology continues to advance, businesses can struggle to decide on a fraud prevention solution. Aside from the different fraud types to account for (transactional, account takeover, identity theft, etc.), there seems to be a new fraud-fighting technology hitting the market every other day. Two technologies in particular — behavioral analytics and behavioral biometrics — have gained a lot of attention in the fraud prevention industry. But they’ve also stirred up a lot of confusion. Let's break it down:
Biometrics are physical characteristics used to identify a person. The most common types of biometric identifiers are voice, iris, fingerprint, facial profile, and palm/finger vein patterns.
From a technology perspective, biometric authentication is a security process that uses a person’s physical traits to verify their identity. Popular authentication methods include fingerprint scanners, iris scanners, and facial and voice recognition systems.
Biometric security is becoming common in everyday life — mobile phones unlock with the touch of a thumb, travelers scan their eyes and fingerprints to get through airport security, and certain devices can be triggered by a person’s voice. But when it comes to fraud prevention, biometric authentication faces many challenges. The rise in AI, digital voice cloning, and deepfake technology is making it easier for fraudsters to mimic and replicate real humans. Cybercriminals are also becoming better at stealing biometric data which, once stolen, is nearly impossible to change. If someone steals your fingerprint, you can’t simply go out and buy a new one. Biometric technology itself is also prone to data breaches. So, while biometrics are helpful in the fight against fraud, they’re not a perfect solution on their own.
Behavioral biometrics identifies measurable patterns in human activities. Instead of using a fingerprint, face, or iris (physical biometrics) to identify a person, behavioral biometrics looks at a person’s unique behaviors and actions across the digital landscape. Think of it as digital body language.
Types of behavioral biometrics include:
In fraud prevention, behavioral biometrics are used to either confirm identity or detect anomalies in a user’s behavior. From a sudden change in typing speed to a shift in how a person uses their mouse, it uses multiple data points to spot patterns and distinguish between a legitimate user versus a fraudster or bot. Many companies rely on behavioral biometrics to verify the identity of visitors and customers, especially when they’re attempting to open a new account or change an existing profile.
“Analytics” is a familiar word: it’s a field of computer science that turns raw data into insight so people can make better decisions. Behavioral analytics follows the same concept but focuses on revealing patterns in behavior. It’s the process of collecting and analyzing user data to understand and predict a person’s online behavior. Studying a user’s interactions on a website or app — what they click on, the time they spend on a page, how they search or filter, etc.— reveals insight into their interests. This information can then be used to predict trends, understand preferences, and improve the user experience. It can also be used to spot fraud.
Types of behavior that can be tracked with analytics include:
In fraud prevention, behavioral analytics are great for spotting transactional fraud. Machine learning and automation can analyze large sets of data quickly to reveal anomalies that deviate from normal user behavior. For example, credit card providers can establish a baseline behavior for a customer based on their habits like purchase and browsing history. When something unusual happens (the customer buys a cappuccino in Chicago and, 10 minutes later, fills up their gas tank in Paris), behavioral analytics can spot the fraudulent activity. The bank can then notify the customer of the suspicious activity, stop the transaction, or freeze the card.
Because it analyzes large sets of data, behavioral analytics can catch and flag questionable actions on a broad scale. It can also help to predict future actions.
Now that you understand the differences between the technologies, which solution will best meet your fraud prevention needs? The answer isn’t black and white — it depends on your use case and what you’re trying to accomplish. Here’s a quick summary:
Biometrics are specific, tangible characteristics used to validate a user’s identity. Fingerprints, facial features, and voice are the most common.
Behavioral biometrics uses specific behavioral traits to identify a person. From typing patterns to mouse movements, behavioral biometrics help to build a comprehensive identity profile that can be used to compare every interaction. It enables organizations to compare “me vs. me” for more accurate identity verification.
Behavioral analytics examines behavior patterns. How consumers interact with a website creates a particular pattern of expected behavior. It connects a user’s behavior to their intention, not their identity. Behavioral analytics compare "me vs. fraudster" very effectively.
When it comes to choosing the right fraud solution for your business, it’s important to remember that fraud and cyber-attacks are becoming more common, sophisticated, and expensive. While each of the technologies mentioned has specific strengths, leveraging all three in unison, with one end-to-end platform, is the most efficient way to fight all types of fraud.
The best approach to keeping fraudsters at bay is a multi-layered fraud defense solution that combines traditional identity verification methods with advanced fraud detection. Technology that leverages real-time data capture, behavioral biometrics, AND behavioral analytics is the best way to truly get ahead of evolving fraud.
