In an era of digital transformation and rising cyber threats, traditional passwords and PINs are no longer sufficient to protect sensitive data and control access. Biometric authentication and identification Market Share offer a more secure and convenient alternative by verifying individuals based on their unique biological traits. From unlocking smartphones to securing national borders, biometrics is rapidly reshaping how identity is managed across industries.

What is Biometric Authentication & Identification?

Biometric authentication verifies a person's identity by comparing live biometric data (e.g., fingerprint, face scan) to stored data—used for login or access.
Biometric identification, on the other hand, determines who a person is by matching their biometric data against a large database of profiles—used in law enforcement, immigration, and surveillance.

Common Biometric Modalities:

• Fingerprint recognition

• Facial recognition

• Iris and retina scanning

• Voice recognition

• Palm vein and hand geometry

• Gait analysis

• Behavioral biometrics (typing rhythm, mouse movement)

How It Works

1. Enrollment

User’s biometric data is captured using a sensor and stored in a secured database or device in the form of a digital template.

2. Authentication (1:1 Matching)

Biometric input is matched with the stored template to verify identity (e.g., unlocking a device or approving a transaction).

3. Identification (1:N Matching)

Biometric input is searched against a database to find a match (e.g., identifying a person in a crowd or at a border).
