Biometric authentication, which relies on unique biological traits for identity verification, faces a significant threat from increasingly sophisticated spoofing attacks, including the use of deepfakes. These attacks use various methods, such as fake fingerprints, photos, and advanced AI-generated media, to deceive systems across multiple modalities like fingerprint, face, iris, and voice recognition. Liveness detection plays a crucial role in mitigating these threats by determining whether the biometric data originates from a live person, employing both passive and active techniques to enhance security. Presentation Attack Detection (PAD) technologies, guided by ISO/IEC standards, utilize tools like 3D depth sensing and texture analysis to counter spoofing attempts. Companies like Didit offer advanced solutions with high accuracy in liveness detection and continuous updates to their algorithms to combat emerging threats, emphasizing the importance of a multi-layered approach to maintain robust biometric security.
