They developed EMIRIS, a method that reconstructs iris information by analyzing electromagnetic emissions during sensor data transmission. Using a tailored diffusion model for denoising and restoration, the technique achieved 0.511 average SSIM and successfully spoofed commercial iris recognition systems with 53.47% success rate across 3,000+ samples from 50 users, demonstrating significant privacy risks in biometric authentication systems. ## Full article daily.dev links to this article rather than hosting it.
