Abstract This thesis presents the design, implementation and anlaysis of a dual biometric system. The system's primary functions were the authentication and verification of a person, based on their unique biometric profile. The biometric methods selected were facial recognition and hand gesture recognition, both implemented as separate systems and then combined, to form the dual system. Futhermore, the systems were created with the utilization of inexpensive and readily available hardware in order...

Abstract AI-driven phishing, spoofing, and deepfake attacks pose escalating risks across email systems, educational platforms, and digital social spaces. Publicly available tools now enable adversaries to generate convincing impersonations, bypass conventional defenses, and exploit human trust through email spoofing, voice cloning, and real-time face swapping. These threats highlight the limitations of traditional security awareness training and automated filters when faced with adaptive,...
