The global demand for biometric authentication is growing, so the face recognition market reached an unprecedented rate of approximately $4 billion and is expected to grow. Biometric verification allows firms to make strides towards ubiquity, and developers must keep up with scammers who want to intervene in the verification procedure. Another way developers secure biometric authentication is through a collection of authentication techniques, that is “3D liveness detection”.
This blog will talk about liveness detection, its benefits, and how does it works.
A Quick Insight of Biometric Authentication
Biometric authentication is a process or software used to access restricted devices by using a biometric source, including fingerprint, facial, and retain scan as an authenticator. In today’s digital world, Touch ID and Face ID are two examples of biometric verification that help individuals access their personal devices by using a passcode and PIN for a more user-friendly experience.
Biometric authentication is famous for its efficacy and convenience, and like other technologies, it secures users from fraud. It’s the point where liveness detection comes into play.
What is 3D Liveness Detection?
As in heist movies, the actors do magic by using masks, images, and fake fingers to dodge biometric systems, and these certain types of attacks are known as presentation attacks. Now, these sci-fi movies have turned into reality.
Through liveness detection, the software quickly monitors and analyzes if the user is real or fake by requesting them to do specific actions such as head nodding, eyes blinking, and smiling. It’s all used to restrict scammers, limit spoofing attacks, improve overall efficiency, and increase employee productivity.
Face liveness check ensures that company data is secure and not any unwanted user is trying to gain sensitive and personal information for illegal purposes. Biometric verification ensures that a set of strategies verifies an accurate person, not an imposter. For instance, the thumbprint, actual eye, and user's face are real and not of any imposter.
Defrauders and criminals are looking for ways to trick biometric systems, that’s why firms have to make liveness detection a part of their work to secure their premises and data from any scammers. Liveness detection has different forms, and firms must ensure them to keep them safe.
Working of 3D Liveness Detection
Through different ways, liveness detection technology can be used to combat spoofing, and the following are a few of them. This helps in combatting presentation attacks and secures firms from getting into the hands of scammers.
Active Liveness Detection
Active liveness detection needs any sort of individual input such as blinking of eyes, nodding their head, and smiling. Authenticate a thumbprint by placing it on the scanner and by following directions such as moving the head at 360 degrees.
Passive Liveness Detection
Passive liveness checks work in the background and don’t need any user input as needed in active liveness detection. It just verifies through natural movements to provide more frictionless verification.
Hybrid Liveness Detection
Hybrid liveness detection is a combination of both active and passive liveness detection but a less intrusive solution. Developers usually opt for hybrid or passive liveness detection methods due to their UX-friendly technique.
Response and Challenge
Response and challenge come under active liveness detection as it asks the user to give a response to prompt action such as moving the head, blinking, and smiling. The primary goal is to combat false presentations such as 2D images and video replays to prove that the user is live.
Depth and Motion Perception
Biometric authenticators use 3D liveness detection when it comes to verification as it helps in 3D mapping and combatting spoofing attacks. 3D liveness detection uses in-depth perception to gather information about subtle changes that make it hard for scammers to defeat.
Artificial Intelligence and Algorithm
Many biometric verification systems use advanced algorithms to authenticate if a sample is accurate or from preregistered sources. Biometric samples enhance machine learning and artificial intelligence incorporation by identifying subtle changes to an authorized person's face, including glasses and facial hair.
Multi-Modality
Biometric inputs require a blend of retinal, facial, thumbprint, and vocal scans that is one of the secure ways to use advanced biometric systems. A sophisticated scammers can fool the biometric authenticator as they want to continuously add in the company's confidential information.
Final Verdict
3d liveness detection is essential to reduce spoofing attacks and allows firms to help in securing their confidential information. Active, passive, and hybrid liveness detection plays a vital role in this regard. Liveness detection working varies from software to software so firms must apply that system which is according to their needs and can improve their overall efficiency.
