In an age where digital security breaches are an increasingly common occurrence, we want and need to feel safe when we are accessing our personal information. What if there was an authentication method that could combine multiple biological markers (face, fingerprint, and voice) to form one unified and virtually-bulletproof method of authenticating your identity? The future is here and now. It is called multi-biometric identity authentication.
The Rise of Multi-Biometric Authentication
Back in the day, you could use a password to keep your information secure. However, as cyber-security threats increase, so do the ways we need to keep information safe. This is where multi-biometric identity authentication comes in.
Using various human characteristics and traits, including facial identification, iris scanning, fingerprint recognition, and voice detection, security systems can compose and develop a highly precise interface through which to identify and validate someone’s identity.
This is the next era in security information technology since a single characteristic can be easily compromised. A hacker can determine your password, regardless of how complicated you believe it may be. Taking multiple characteristics from a physical account significantly reduces the chances of a breach.
Effect on Security

You may be wondering when and how we can actually use this security technology. Well, take your smartphone as an example. If it’s on the newer side, you may have facial or fingerprint recognition to easily unlock it. It’s only one of the vast areas where this new science can be implemented. Banks, government entities, and corporate powers are now implementing more intricate security systems in their workplace to keep company and personal information more secure.
A prime example of this is in the financial industry, where many banks now have the capability to give their customers multi-biometric-enabled identification using their facial image, fingerprint, or by scanning their iris for card-less transactions. The healthcare industry is also putting this innovation to good use for securely accessing patient medical records by verifying the identity with biometrics.
How It Works
The underpinning of multi-biometric authentication ultimately comes down to complex algorithms and artificial intelligence (AI). Complex systems can be worked behind the scenes to quickly compare and analyze multiple biometric identification providers in real-time to ensure the person requesting access is exactly who they say that they are.
One of the many benefits of multi-biometric identity authentication is its flexibility. It doesn’t rely on a single identification method. Instead, it draws on several different types of identification, making it easier to defeat would-be thieves and combat mistakes. Whether that means recognizing a face from various angles or being absolutely certain that a fingerprint scan matches the assigned party, the system is far more precise than anything existing in the past.
What’s Next for Identity Verification?
Advances in multi-biometric authentication are only going to get better. We’ll see far more biometric identification integrated into our daily lives, from using fingerprints to sign into our workplace to having faster, more efficient, and securely designed e-commerce experiences. Integrations are going to be faster, more accurate, and easier to use.
