Our fingerprints, voice, facial patterns, iris, and even body odour play an important role in biometric verification and identification. As biometric technology takes centre stage, these unique traits can be combined in various ways to improve security and create a more reliable authentication system. You experience this firsthand every time you unlock your smartphone with your face or fingerprint. With AI and machine learning advancing rapidly, 2025 is poised to be a pivotal year for the future of biometrics. Here’s what’s ahead.
8 Biometric Trends to Watch in 2025
We must first look at the future to understand where the future of biometrics is going. What social and technological changes are shaping it? How will they affect security and identity verification? Can we control these changes, and if so, who has the power to do so?
Along with exploring these trends, we’ll also see which can help us adapt to a fast-changing world.
1. Remote Health Monitoring
Biometrics is changing telemedicine by allowing secure authentication for remote healthcare workers. With biometric verification, healthcare providers can offer professional consultations in a timely while protecting patient data over the cloud.
During identification, the system compares scanned biometric data of these healthcare providers with stored profiles, instantly verifying the identity of those who have opted for remote doctors on demand. Advanced methods like palm vein recognition, iris scans, and voice authentication are in the way to streamline patient registration, keeping every citizen equal and their opportunities flexible.
2. Decentralized Finance (DeFi)
Decentralized finance (DeFi) is a popular trend for any financial function without a third party, i.e., a bank. Technology and finance breed a common ground, reshaping how we interact with financial services such as accepting deposits, lending loans, transferring funds, etc. Using physical and behavioural traits like fingerprints, iris scans, and facial recognition, biometric technology is becoming a crucial pillar in DeFi platforms.
As DeFi expands, integrating biometrics into Know Your Customer (KYC) procedures has become essential. It speeds up onboarding by completely replacing physical and online forms, improves the user experience by transferring your data from your IDs straight to the bank, and ensures compliance with regulations like Anti-Money Laundering (AML) protocols.
Once a user’s identity is verified, they can perform transactions without repeatedly proving who they are. This seamless process enhances security while making DeFi platforms more user-friendly.
3. Voice Biometrics
Voice biometrics is one of today's safest and most convenient authentication methods. One big advantage is that it works without special tools, device setup, expensive cameras, or extra apps. It’s simple and hassle-free.
Consumers can access the service via phone, smartphone, or web app. This makes it easier for organizations to serve all users, regardless of age, income, tech skills, or smartphone ownership.
Voice verification works in real-time during the conversation, ensuring security even if circumstances or people change on the other end. Another key advantage is that users don’t need to share personal or confidential information except for their voice for authentication.
Moreover, AI-powered technology can detect a caller’s emotions and intent. For example, if someone calls their bank to transfer a large sum of money but sounds distressed—possibly under duress—the system acts as a safeguard. Instead of processing the request, it may respond with a message stating that the service is temporarily unavailable and advise the caller to visit a nearby branch for assistance.
4. Multi-Modal Biometrics
With various types of biometrics available today, combining multiple methods was inevitable. This multimodal approach strengthens security by layering different biometric techniques, making authentication far more reliable than relying on just one.
Beyond security, multimodal systems also tackle real-world challenges. Poor lighting, background noise, or natural changes in a person’s features over time can impact accuracy, but using multiple biometrics ensures seamless verification in any situation. Looking ahead, these systems will integrate smoothly into existing frameworks, making biometric security more robust, smarter, and more accessible for all.
5. Advanced Presentation Attack Detection (PAD)
Presentation Attack Detection (PAD) is a strong defence against biometric fraud. It ensures that fingerprints, facial scans, voice authentication, and iris recognition come from a real, live person—not a fake image, recorded voice, or AI-generated deepfake. By verifying both the user’s presence and their identity documents, PAD prevents fraud before it happens.
Biometric security analyses patterns and tests them against known data to tell real users apart from threats. It relies on two main factors. Physical biometrics include fingerprints, facial features, voiceprints, and iris patterns—unique traits that cannot be stolen or easily faked. For example, facial recognition systems turn an image into a mathematical code, making it impossible to recreate the original face from stored data.
Behavioural biometrics focuses on how people interact with technology, such as how they type, swipe on a screen, or walk. These patterns are monitored in the background, adding an extra layer of security without slowing down the user experience.
6. Edge Computing
Until now, biometric data has mostly been processed in the cloud, where it has had to travel to a central server before authentication. This worked, but it wasn’t perfect. It meant longer wait times, privacy concerns, and the risk of cyberattacks while data was being transmitted. Edge computing changes that by keeping the data local—right on the device or nearby, instead of sending it across the internet.
Think about unlocking your phone with your face. Instead of sending that image to a cloud server, your phone processes it instantly. The same idea is now being applied to banking, healthcare, smart homes, and security systems—making everything faster, safer, and more private.
7. Live Detection
Artificial intelligence is giving biometrics a serious upgrade. It doesn’t just compare fingerprints or facial features—it learns and adapts. It can recognize people even if they change their hairstyle, grow a beard, or wear glasses. AI also helps spot fraud by detecting tiny details that humans or older systems might miss, like unusual voice patterns or micro-expressions on a face.
A big breakthrough is liveness detection—ensuring the person being scanned is real and present, not just a photo, deepfake, or recorded voice. AI can now catch subtle movements, like how your pupils react to light or how your voice naturally shifts when speaking, making it almost impossible to trick the system.
8. Automotive Security and Personalization
Hyundai recently introduced an SUV with fingerprint recognition for enhanced security and convenience. Biometric sensors are strategically placed near the door handle and ignition, allowing only registered users to unlock and start the vehicle.
Facial recognition is also gaining traction among car manufacturers. As a driver approaches, the system identifies them and automatically adjusts settings, including seat position, climate control, and entertainment preferences, creating a personalized driving experience.
What’s Next For The Future Of Biometrics?
By 2025, biometric authentication will be everywhere, blending into daily life so smoothly that we barely notice it. Smart home systems will recognize your face when you walk in. ATMs will verify your identity with a quick fingerprint scan. Banks will use voice recognition to detect if someone is being forced into making a fraudulent transaction. Even online shopping could become safer, with AI monitoring behavioural patterns to catch suspicious activity before fraud happens.
The future of biometrics is more about convenience than just security. Instead of memorizing passwords or worrying about stolen credentials, our unique traits will become the key to everything.
