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…
rPPG-SysDiaGAN: Systolic-Diastolic Feature Localization in rPPG Using Generative Adversarial Network with Multi-Domain Discriminator
Banafsheh Adami, Nima Karimian
Remote photoplethysmography (rPPG) offers a novel approach to noninvasive monitoring of vital signs, such as respiratory rate, utilizing a camera. Although several supervised and s…
GRU-AUNet: A Domain Adaptation Framework for Contactless Fingerprint Presentation Attack Detection
Banafsheh Adami, Nima Karimian
Although contactless fingerprints offer user comfort, they are more vulnerable to spoofing. The current solution for anti-spoofing in the area of contactless fingerprints relies on…
Contactless Fingerprint Biometric Anti-Spoofing: An Unsupervised Deep Learning Approach
Banafsheh Adami, Nima Karimian
Contactless fingerprint recognition offers a higher level of user comfort and addresses hygiene concerns more effectively. However, it is also more vulnerable to presentation attac…
A Universal Anti-Spoofing Approach for Contactless Fingerprint Biometric Systems
Banafsheh Adami, Sara Tehranipoor, Nasser Nasrabadi +1
With the increasing integration of smartphones into our daily lives, fingerphotos are becoming a potential contactless authentication method. While it offers convenience, it is als…
