NDSS 2025 – EMIRIS: Eavesdropping On Iris Information Via Electromagnetic Side Channel

This research paper (EMIRIS) shows that electromagnetic emissions from near-infrared iris sensors leak enough information to reconstruct iris images; the authors decode the sensor transmission format, reconstruct iris textures using an inverse problem formulation and a diffusion model, and report that reconstructed irises can spoof classical iris recognition models with a ~53.5% success rate on a dataset of >3,000 samples, posing a practical privacy and authentication risk for systems using such sensors.
