What is Biometric Authentication?


Biometric authentication is indeed an advanced technology that takes into account the biometric data retrieved from a physical user to cross-match these details against a particular device or security area which the person is trying to access. Suppose you want to fully secure an area or a particular digital asset from unauthorized personnel, your best bet is to render the services of biometric authentication systems.

These systems are extremely authentic and unique in their assessing and differentiation of an authorized person from an unauthorized one. Both the biological and certain physical traits of the person trying to access a secured entity can be used to determine whether to grant access or not. If the identity of the person is verified from biometric authentication then access to the device or secured area is granted, otherwise, other security-related events are triggered to protect the assets being approached by unauthorized users.

Traditional Biometric Verification Methods

Traditional Biometric Verification Methods

There are a variety of options when it comes to authentication of the true identity of a person such as traditional authentication methods. These methods are necessarily old and don’t back up the very foundation of digital technology they are developed to protect, meaning that these traditional systems can’t serve in a highly advanced and digitally palpating era. However, a few of them are mentioned here for your ease and convenience to determine the adversity that surrounds these traditional systems of authentication;

Password-based Authentication

This is a way of authenticating your identity over the internet scrolling through websites and clusters of servers that grip a particular website together. It is considered a traditional way of authentication because passwords can be unique and serve to protect your digital assets on the internet can easily be hacked or manipulated. When you have to access something confidential or private to a particular user say yourself, then you would have to provide a valid username and a password to the server which would authenticate against the hash data stored within it. If everything goes smoothly then access to your secured content is granted, otherwise not.

Knowledge-based Authentication

Knowledge-based authentication is used by a variety of websites and companies as the proprietary means to grant access to the right users. Suppose you have to grab access to a particular site that uses this protocol what would you do? Well, for starters you would have to answer a series of security questions otherwise known as KBA or knowledge-based authentication protocol. These security questions are already provided to you by the company or website you are trying to access. This is one of the most entailing security parameters that companies implement these days to keep information safe in the right hands.

Token-based Authentication

If you attend to the existence of token on its own then it has no particular meaning in the whole world wide web. But when combined with the right set of data or introduced into a tokenization system can be used to request access to secured channels of information. Such assets are meant to be secured or encrypted from access from illicit cybercriminals or nonauthorized users.

Tokenization system will generate a request as per your behalf having a digitally signed token which then would be authenticated by the server to grant access.

Out-of-band Authentication

Out of band authentication, in reality, is a two-factor authentication system (2-Step Verification or Multi-Factor Autentication) that takes into account the users trying to access the encrypted channels to provide with a second source of authentication. The first factor could be a key phrase or a password and the second factor would be to enter another pin sent by SMS to your registered mobile number or making a call from that same phone number to have access to your account. Mainly financial institutions are more derived to practice such methods of authentication for their safety and of their customers.

Biometric Authentication Technology

Biometric Authentication Technology

This is the advanced level of authentication system that comes with a digital array of recognized elements by this technology that can be used to authenticate a potential user. A few generalized types are as follows:

Fingerprint Scanners

The verification of your identity is brought together with the help of authenticating your identity via your fingerprints. When your finger or palm registered within the scanner touches the scanning surface, a digital code is automatically generated which is cross-referenced with the one secured within the servers to grant access.

Retina and Iris Recognition

The verification of your identity such as for unlocking a secured device or having access to an otherwise sealed/confidential area can also be regulated by the means of using retina authentication. Retina and iris scanning are done by advanced scanners that map out the physical structure of retinal or iris tissues of the human eyes and then cross-referencing the details to grant access.

Voice Detection

This is rather an advanced approach in which you would have to speak aloud a particular phrase or sequence of numbers, vowels or words to help the voice detection system to authenticate your identity.

Facial Recognition

Facial recognition is extremely common these days and is extensively practiced, your face is scanned with the help of highly detailed infrared segmentation using a highly advanced camera system. Your face is mapped into digital arrays for the detection system to authenticate and once approve your will be granted access at once.

Liveness Detection

Liveness detection is the most advanced and potent authentication-based technology you can come around to this date. It uses a special algorithm stored within the digitally advanced security systems to make sure that the image of the face or that of retinal or iris scan the system is receiving comes from a trusted, authenticated and alive source. This system can beat any fraud or spoofing done by unauthorized personnel to gain access to the secured systems.

Biometrics in the Verification Process

Biometrics in the Verification Process

As you have come around both the traditional and biometric systems of authentication can be used to verify the true identity of a user from that of fraud or imitator. Biometrics have relayed a digitally advanced and potent security system that can help you in today’s advanced and dangerous world out there. All your effects, data or information are better secured under the biometrics verification systems, as each verification process is designed to cross-check the information using a secured and error-free approach. It is to determine that it is an authenticated user trying to access their digital data using secure & authenticated channels regulated by the biometrics systems for user verification.

Here in iDenfy to provide identity verification service, biometric verification systems like face recognition, liveness detection is an essential part.
