Biometric Security – What is It & Why Does it Matter Today?

Introduction

Can your palm prints reveal your destiny? Maybe Yes or No but definitely something more tangible- your identity. We are talking about biometric security, probably, the most dependable security barrier that leverages what is uniquely yours - like your fingerprints, face scan, iris pattern, or voice. The term ‘biometric’ is derived from two Greek words Bio (life) and Metric (measure). Together, the term means assessing a user’s biological traits as a unique security authentication factor. This particular factor is all set to fuel the global biometric market which is projected to reach $83 billion by 2028, reflecting its growing adoption. Let’s unfold more in this insightful read.

What is biometric security?

Biometric security is all about verifying your (users) unique physical characteristics - such as fingerprints, palm prints, facial scans, iris pattern, and voice - to grant access to a protected place. A biometric security system uses the data gathered as immutable defense against advanced cyber attacks. Additionally, innovations like 3D mapping in facial recognitions and multi-spectral imaging have heightened the accuracy and reliability of biometric as the new standard of security authentication. A common example of biometric authentication is unlocking your phone and apps with touch IDs like fingerprints or face scans. Then, office check-ins with your fingerprints on biometric systems is another popular example of biometric security scan.

How does it work?

The entire mechanism of biometric authentication systems is based on constant capturing of biometric data, and comparison with a saved database - to find a match. If the collected data matches the saved database, the biometric system will grant secure access. All biometric systems are equipped with 3 basic components such as:

• A sensor or reader for capturing and verifying users’ bio data
• A program or software that records the scanned data for seamless comparison with any new data
• Lastly, a database that analyses the characteristics of the stored data and transforms it to a graph or code to perform the actual comparisons

Presenting a brief synopsis on how your physical data is processed by the biometric access control system

• Enrollment: The first step that records information about you like your name and identification number, proceeded by capturing your biometric traits.
• Storage: In this step, the system analyses your every trait to translate it into a graph or code. In some cases, the data is even recorded in smart cards like credit cards that you use daily.
• Comparison: This is when the system decides to let you in or reject requests by comparing your stored data.

Significance of biometric security in today’s age

Biometric security technology has become a cornerstone of digital security and convenience in the modern world. With the growing need for impenetrable defense systems, the significance of biometric security systems has become more vital than ever.

Why Biometrics Matters:

Enhanced Security of course. Users' physical data like fingerprints, iris scans, and facial recognition provide a unique layer of security since these unique traits are almost impossible to replicate.
Passwords can be forgotten or stolen, but your biometric traits are always with you.

Seamless and Safe Access:

Whether it's about unlocking phones, making payments, or accessing accounts, using face or fingerprint recognition has made life simpler over remembering countless passwords.

Proactive Fraud Prevention:

In sectors like banking, finance and insurance, biometrics prevent scammers by verifying a user's identity with greater precision. It ensures that even if someone has your login credentials, they can’t access them without you.

Wider Applications:

Beyond personal devices, biometrics is now used commercially in airports (for quick check-ins), healthcare (for seamless patient care), and workplaces (to track daily attendance)

Pro Safety Tips:

Your biometric data is exclusive, and it’s important to safeguard it. So, don’t make your biometric data easily accessible.
Refrain from uploading close-up face images, palm prints, or any other biometric details on unknown apps like astrology or entertainment platforms. Many of these apps can misuse your data for unethical purposes.

Conclusion

Biometric security is a game-changer in safeguarding your personal data with your physical data. However, understanding its nuances is crucial to ensure 100% protection. If you're passionate about enhancing security skills, consider a cybersecurity certification for beginners - a perfect starting point to navigate and secure a desirable job role in the evolving digital landscape. On a final note, always treat your biometric details as precious as your financial information.
