Abstract

Traditional web authentication systems face significant challenges from sophisticated spoofing attacks and lack of continuous verification mechanisms. This paper presents a novel CNN-based multimodal biometric framework that integrates face recognition, voice authentication, and liveness detection with continuous trust scoring for secure web authentication aligned with Zero Trust Access Control (ZTAC) principles. The proposed system employs deep Convolutional Neural Networks (CNNs) for facial feature extraction and anti-spoofing detection, Mel-Frequency Cepstral Coefficients (MFCC) for voice authentication, and real-time liveness detection using temporal analysis. A continuous trust scoring mechanism dynamically evaluates user authenticity throughout sessions, enabling adaptive access control. The framework addresses critical limitations of existing single-modality systems by providing robust defense against presentation attacks including photo spoofing, video replay attacks, and voice synthesis. Experimental validation demonstrates superior performance in detecting spoofing attempts while maintaining usability for legitimate users. The system’s web-deployable architecture with low-latency APIs makes it suitable for modern distributed environments requiring stringent security measures.
