Biometrics

Biometric authentication is a security process that uses unique physical or behavioural characteristics to verify individuals’ identity. Here are three commonly used methods, along with their advantages and disadvantages:

Fingerprint Recognition: Biometric technology that identifies individuals based on the unique patterns in their fingerprints.

Advantages:

·       Highly unique fingerprints are distinct even among identical twins.

·       Fast authentication with minimal user effort.

·       Compact and easy-to-integrate scanners.

Disadvantages:

·       Can be compromised if fingerprints are stolen or copied.

·       May not work well for individuals with worn or damaged fingerprints.

·       Some materials (e.g., gloves or moisture) can affect accuracy.

 

Facial Recognition: Works by matching the faces of people within range of special cameras identifying individuals by analysing the unique patterns of their facial features.

Advantages:

·       Contactless authentication, making it convenient and hygienic.

·       Works well in various environments and lighting conditions.

·       Can be integrated with cameras for seamless authentication.

Disadvantages:

·       Privacy concerns arise due to potential surveillance and data storage.

·       May be tricked by high-quality photos or deepfake technology.

·       Accuracy can be affected by changes in appearance (e.g., aging, makeup, facial hair).

 

Iris Scanning: Biometric identification method that utilizes the unique patterns in the iris, the coloured part of the eye, to identify individuals.

Advantages:

·       Extremely accurate and reliable due to the unique patterns in the iris.

·       Works well even in low-light conditions.

·       Harder to spoof than fingerprints or facial recognition.

Disadvantages:

·       Requires specialized cameras, making it expensive to implement.

·       Can be affected by eye conditions or reflections from glasses.

·       Some users find it uncomfortable or invasive.
