Description: Liveness detection is a technique used in biometric authentication that ensures that the provided sample comes from a living person, rather than a mold, image, or any other type of non-living representation. This process is crucial for enhancing the security of authentication systems, as biometric techniques such as facial recognition, fingerprinting, or iris scanning can be vulnerable to spoofing attacks. Liveness detection relies on identifying physiological or behavioral characteristics that are unique to living beings. For example, it may include detecting pulse, eye movement, skin temperature, or response to stimuli. These characteristics help ensure that the user attempting to access a system is indeed who they claim to be, adding an extra layer of security in multifactor authentication. Implementing liveness detection not only improves the reliability of biometric systems but also fosters user trust in the technology by reducing the risk of fraud and unauthorized access.
