Using biometric authentication systems is expensive and requires special hardware, software and infrastructure.

Cultural and social acceptance:

Some individuals may have cultural or social restrictions regarding the provision of biometric data, which may lead to refusals or objections to accept biometric authentication.

False recognition and denial of authenticity:

Biometric systems can have false recognition (recognition of impostors) or denial of authenticity (removal of legitimate users), affecting accuracy and reliability. 

Organisations considering using biometric authentication should carefully consider the advantages and disadvantages to strike a balance that addresses security concerns while considering users’ privacy and assurance.

Types of Biometric Authentication 

Fingerprint Scanners:

Fingerprint scanning is one of the most common types of biometric authentication used in multiple devices to protect from security threats. It records swirls and ridges of an individual’s fingerprints. Also, a fingerprint is the unique part of a human that describes his identity. Everyone has unique fingerprints. Even twins have different fingerprints on their hands.

The latest version of fingerprint devices advanced the scanning of vascular patterns of an individual’s fingers. However, fingerprint technology is not fully secured and has its flaws. Despite that, it is one of the most reliable and popular technologies used by many organizations and customers.

Facial recognition:

Another popular method of Biometric authentication is Facial recognition. Facial recognition is a method that matches different angles and measurements of a user’s face. The imprints that are taken from our faces are called faceprints. Faceprints are used in many devices, such as mobile and laptops, to complete identity verification.

Facial identification is increasingly getting popular in Banking and maintaining digital payment security. This technology is almost utilised in all the digital payment apps Apple Pay, Selfie Pay, and AliPay for added security protection.
