Biometric authentication is a method of identifying and verifying a person’s identity based on their physical or behavioral characteristics.
This technology uses unique traits of a person, such as fingerprints, facial features, iris patterns, voice, or even walking style. Since biometric data is unique to each individual, it provides a very high level of security.
🔹 How Does It Work?
-
The user provides biometric data (e.g., fingerprint, face scan).
-
The system compares the provided data with pre-stored samples in its database.
-
If the data matches, access is granted; if not, access is denied.
🔹 Types of Biometric Authentication
| Type | Description |
|---|---|
| Fingerprint | The most common method, used in smartphones, bank apps, and security systems. |
| Facial Recognition | A camera analyzes the unique features of a person’s face (e.g., Face ID, CCTV systems). |
| Iris Recognition | Identifies unique patterns in the iris of the eye, providing high accuracy. |
| Voice Recognition | Each person’s voice is unique, and it can be used to authenticate identity. |
| Palm or Vein Recognition | Scans the vein patterns in the palm or hand for identification. |
🔹 Where Is It Used?
| Field | Examples of Use |
|---|---|
| Smartphones | Unlocking the screen with Face ID or fingerprint. |
| Banking Services | Accessing mobile apps, confirming transactions. |
| Government Systems | Passport control, voting, identity verification. |
| Corporate Systems | Accessing offices, time tracking at work. |
| Airports | Fast border checks, identity verification for passengers. |
