Physical Adversarial Attacks Using Fan-Based Holographic Projections
- Planned and executed black-box adversarial testing of traffic-sign computer-vision pipelines; produced a threat model and attack-surface analysis for safety-critical scenarios
- Built a programmable hardware proof of concept using a holographic POV fan and a repeatable test harness to run real-time experiments and collect evidence for vulnerability assessment
- Quantified misclassification across lighting, distance, and angle, achieving up to 90% untargeted misclassification; delivered steps to reproduce, PoCs, and prioritized mitigations; documented limitations and residual risk
