Researcher
Haoyu Zhang is a Researcher at the Department of Information Security and Communication Technology, Norwegian University of Science and Technology (NTNU), Gjøvik. His primary research focuses on biometric security with specialization in face recognition systems and countermeasures against morphing attacks. His research program centers on synthetic data generation for biometric security, including techniques like SynMorph for creating morphed face datasets and MIPGAN for identity-prior-driven attack generation. He investigates deep learning architectures such as Vision Transformers and diffusion models for morphing attack detection, while also exploring synthetic ethnicity alteration to address dataset bias and remote photoplethysmography for liveness detection. His work bridges theoretical generative models with practical security applications in face recognition pipelines. Publication analysis from 2021-2025 reveals a cohesive research trajectory advancing morphing attack methodologies through three interconnected strands: attack generation (e.g., MIPGAN, SynMorph), detection frameworks (e.g., Vision Transformer-based detectors), and dataset enhancement (e.g., synthetic ethnicity alteration). His 2025 doctoral dissertation synthesizes these contributions into a comprehensive framework for morphing attack generation, data augmentation, and detection. The work demonstrates consistent collaboration with Ramachandra, Raja, and Busch across IEEE and Springer venues, establishing him as a contributor to biometric security standardization efforts.
