What is Biometric Authentication?
Biometric authentication is a method of verifying a person’s identity by using unique physical characteristics, such as fingerprints, facial features or the sound of their voice. Unlike traditional authentication methods, such as passwords or security questions, biometric authentication relies on an individual’s unique traits to confirm their identity.
Biometric authentication has become increasingly popular in recent years as a means of protecting sensitive information and systems and has begun to be used in a variety of applications, such as access control systems, online banking and cell phone unlocking.

Here are the types of biometric recognition that exist.
Types of Biometric Authentication
There are several types of biometric authentication, including:
- Fingerprint recognition: involves using a sensor to scan a person’s unique fingerprint patterns to confirm their identity.
- Facial recognition: involves using a camera to capture and analyze the unique features of a person’s face, such as the distance between their eyes and the shape of their jaw.
- Iris recognition: involves capturing and analyzing the unique patterns of the iris, the colored part of the eye.
- Voice recognition: involves analyzing the unique characteristics of a person’s voice, such as pitch and timbre.
Although fingerprint recognition is one of the most common types of biometric authentication, voice biometric recognition has become popular for those services or processes that we perform over the telephone, such as calls to customer service numbers of our bank or our telephone operator.
Voice Biometric Authentication
Focusing on voice biometrics, this authentication consists of using the unique characteristics of a person’s voice to confirm their identity. It is often used as an additional layer of security alongside other forms of authentication, such as passwords or security questions, and can be used in a variety of applications, such as access control systems and online banking.
One of the main advantages of voice biometric authentication is that it is relatively easy to use. A person simply speaks into a microphone and the system verifies his or her identity based on the unique characteristics of his or her voice. It is also non-invasive, as it does not require the person to provide any personal information or physical contact.
There are several tools and technologies that are used for voice biometric authentication. These include voice recognition software, which is used to analyze the unique characteristics of a person’s voice, and voiceprint technology, which creates a digital template of a person’s voice that can be used for comparison.
Among the industries that can benefit from biometrics, one of the industries that could enjoy these advantages the most is BPOs and contact centers. But what are the advantages for contact centers in industries such as banking and telecommunications?
Advantages of Voice Biometric Authentication for Contact Centers
- Optimize operating times: thanks to voice biometrics, contact centers can reduce the average time-to-market (TMO) rate by more than 30 seconds per call. In this way, agents become more efficient and can spend more time resolving customer calls.
- Prevent fraud: customer authentication and verification by voice biometrics is fully secure to prevent fraud and identity theft by using a unique parameter inherent to each person.
- Improve customer experience: voice biometric authentications are much faster and more efficient than traditional authentications through passwords or security questions. Through a natural conversation with a customer or the repetition of a specific phrase, authentication is performed quickly and securely, optimizing operating times, reducing waiting times, preventing fraud and, ultimately, improving the customer experience on every call.
Biometric authentication is a secure and convenient method of verifying a person’s identity and, with advances in technology and the need for secure authentication, it is expected to continue to gain popularity as a means of protecting sensitive information and systems.
