Cross-Layer Roots of Trust: Integrating Biometrics, PUFs, and Hardware Obfuscation
Nima Karimian
Modern cyber--physical, Internet-of-Things (IoT), wearable, and edge systems increasingly require trust in three distinct entities: the human requesting access, the physical device…
DiffAttack: Evasion Attacks Against Face Recognition via Latent Diffusion Models
Omid Ahmadieh, Nima Karimian
Facial biometric identification relies on the distinctiveness of user attributes within a high-dimensional embedding space. However, the decision boundaries of deep face recognitio…
Adv-TGD: Adversarial Text-Guided Diffusion for Face Recognition Impersonation Attacks
Omid Ahmadieh, Nima Karimian
The widespread adoption of face recognition (FR) technologies raises serious privacy concerns, as facial data can be exploited without consent. To address this challenge, we propos…
Robust Spoofed Speech Detection via Temporal Pyramid Modeling
Mahtab Masoudi Nezhad, Nima Karimian
Spoofed speech detection is increasingly challenged by realistic synthesis, voice conversion, and replay attacks, with cross-dataset generalization remaining a major limitation. Th…
