A liveness check is a way of detecting whether a biometric sample is provided by a real and alive person. If the shared sample is just an image or a video, the system will automatically declare it a spoof. It is the newest technology in biometric authentication systems. Since it might be challenging to distinguish between legitimate biometric characteristics and fraudulent activities these days, this technology is available to assist various enterprises. This technology’s primary goal is to improve security by confirming that the biometric sample is taken from a living person. The sophisticated face, 3D, and recorded live detection technology, its advancements, and its use in biometric systems will all be covered in this blog.
Employment of Various Technologies
This particular method uses some of the advanced technologies to verify the user’s authenticity such as voice verification, iris scan, fingerprint sensors, and facial recognition. These technologies are mostly used when it comes to liveness verification. Here are the primary technologies that are being used to detect the fake person:
- Facial recognition is done by asking the user to perform certain actions like smiling and blinking.Â
- Fingerprints are evaluated by observing the pores, temperature, and texture of the skin.
- Iris scanners observe the eye’s reaction to light and the colored part of an eye.Â
- Voice recognition is done by asking the user to utter certain phrases and can easily detect the fake person. Fake voice is usually robotic and doesn’t involve high and low pitch. It has the same pace that can be easily identified.
Types of Liveness Verification
There are two major types of liveness verification methods. Active liveness detection is a process in which the user is asked to perform certain actions such as smiling, blinking, and others. This process may frustrate the users and they might not be able to make natural movements in this method.
On the other hand, the other type of detection is ‘passive liveness detection’. This method doesn’t involve any kind of actions but the system verifies the identity by evaluating the natural movements of the user. It includes the contraction of muscles while talking, smiling, and making other movements.
Significance of Liveness Check
Liveness check is a vital feature that can prevent fraud by detecting a fake identity. The system with a liveness check will only be able to allow the authorized person to enter the premises. It is crucial to maintain a safe and healthy environment. Besides, face liveness detection is an enhanced way of verification apart from the biometric sample.
Moreover, this system of verification can earn users’ trust as liveness checks can also be used in KYC for onboarding new applicants. The strong and enhanced system of verification is more reliable and the users will make sure to give verification daily. It is a very quick and quite handy way for the users. It makes the whole process smooth going.
Limitations and Challenges
To detect spoofs, this technology has gone too far. However, several obstacles may impact its effectiveness. Unsuitable lighting is one example of an environmental element that could negatively impact the verification process. It might be challenging to confirm the identity due to the surrounding noise. Moreover, sensors aren’t very smart at spotting spoofs. A large percentage of false rejections could arise from this. Additionally, some biometric systems are slow and take two or more tries before detecting the spoof. Users may become irritated and waste time as a result.
Furthermore, certain users may have limitations that prevent them from performing face-liveness test actions, such as smiling or blinking. For people with disabilities, this can be annoying. Furthermore, not every user knows how to use this technology. Certain users may experience discomfort and uneasiness as a result of actions like smiling and making facial expressions. By putting in place modern systems that function effectively and fairly for everybody, such difficulties can be overcome.
Conclusion
Technology for liveness detection and deepfake detection is regarded as essential to the dependability of biometric systems and security. It tackles the ongoing problems caused by spoofing attempts. Some cutting-edge techniques that are being used in various fields include machine learning, multispectral imaging, and 3D liveness detection. Liveness detection software will develop and become more complex as research and technology progress, guaranteeing a reliable and intuitive biometric authentication solution for all applications.
