What Is Biometric Verification and How Can it Help You?

Protecting your customer’s personal information and ensuring secure access to their accounts has never been more important. However, traditional authentication methods like passwords and PINs are less reliable in the face of sophisticated identity fraud attacks where the threat of data breaches and financial losses are increasing. Businesses are challenged with striking a balance between approving only good customers and providing a seamless and efficient user experience. Read on to discover how biometric verification offers a cutting-edge solution to confirming identity.

What Is Biometric Verification?

Instead of relying on traditional authentication factors like passwords or physical tokens, biometric verification leverages inherent biological characteristics such as fingerprints, facial features, iris patterns, or voice recognition to identify customers. These biometric samples are matched to an associated, verified identifier or identifiers to allow access to financial ecosystems or other secure environments. Every time you unlock your phone with your fingerprint or face, you’re using biometric verification.

Why Is Biometric Verification Important?

Unlike knowledge-based authentication methods like passwords or PINs, the unique physical traits that biometric verification systems rely on are virtually impossible to replicate or share, which makes them inherently more secure.

By eliminating the need to remember complex passwords or carry physical tokens, biometric verification boosts operational efficiency, streamlines verification processes, and makes the user experience more convenient and seamless.

A prime example of the effectiveness of biometric verification can be seen in the State of Florida’s Homeowner Assistance Fund (HAF) program. To accurately verify 100% of applicants, the program leveraged Socure’s document verification solution to analyze billions of records, ensure the program’s integrity, and provide a seamless experience for eligible homeowners seeking financial assistance.

What Are the Different Types of Biometric Verification?

Biometric verification methods can be broadly categorized into two main types:

Physiological measurements

These rely on an individual’s unique physical characteristics. Some of the most common methods include:

• Fingerprints: Uses the unique patterns of ridges and valleys on an individual’s fingertips and is One of the most reliable and historically successful biometric verification methods.
• Facial recognition: This method is becoming increasingly convenient and widely used and identifies individuals based on their facial features.
• Iris and retina patterns: Considered highly secure, this scans the unique patterns in the iris or at the back of the eye.

Behavioral measurements

Leverage an individual’s unique behavioral characteristics, such as:

• Device patterns: Typing speed, mouse movements, or smartphone usage habits, which can all be measured to detect anomalies and potential fraud attempts.
• Voice waveform recognition: Verifies identity by analyzing the unique characteristics of an individual’s voice, which is useful for customer service applications or voice-controlled systems.
• Signature comparison: Compares a signature against a verified sample to provide an additional layer of authentication for certain transactions or legal documents.

While physiological biometrics are often considered more reliable and secure, behavioral measurements can complement them, offering an added layer of security through multi-factor authentication.

What Is Biometric Verification Used For?

Biometric verification systems are becoming increasingly integral to our daily lives, offering enhanced security and convenience across various domains, including:

Sector-specific uses:

• Finance: Secures transactions and provides customer verification
• Healthcare: Enables patient identification and fraud prevention
• Airport security: Streamlines passenger identity verification
• Commercial: Provides a streamlined user experience for digital onboarding and in-person transactions

Enhancing processes:

• Access control: Managing entry to secure areas, facilities, or systems by verifying authorized individuals
• Employee attendance: Streamlining timekeeping and attendance tracking in workplaces

Integration with MFA systems:

Biometric verification plays a crucial role in multi-factor authentication (MFA) systems, providing the “something a user is” factor in addition to other authentication methods like passwords or tokens. This multi-layered approach significantly enhances security by requiring additional steps to verify an individual’s identity, making it more difficult for unauthorized parties to gain access.

As biometric technology continues to evolve and become more widely adopted, its applications across various sectors and processes will only grow, offering a robust and convenient solution for identity verification and authentication.

What Are The Challenges of Adopting Biometric Verification?

While biometric verification offers significant benefits, its implementation also presents several challenges that need to be addressed. These range from technological limitations to ethical and privacy concerns. Here are some of the main challenges to consider:
