Sommario
On Friday, October 16th, 2026, we will have a new talk for the series #NECSTFridayTalk.During this talk, we will have, as speaker, Luigi Bruzzese, PhD student at Dipartimento di Elettronica, Informazione e Bioingegneria.
Traffic Sign Recognition (TSR) is a safety-critical component widely deployed in modern cars to provide driver assistance. In parallel, urban environments have normalized the presence of stickers and other artistic modifications on traffic signs, making them rarely perceived as suspicious. This coexistence creates a realistic attack surface.
We propose a black-box adversarial pipeline that leverages realistic urban sticker designs to induce misclassification and disappearance in TSR systems.
We evaluate our approach targeting 11 sign categories, and validate the resulting attacks against 7 commercial vehicles, inducing incorrect detections in 59% of cases on average.
A human survey further suggests that our perturbations are perceived as more natural than existing methods, closely mimicking authentic urban vandalism. These findings demonstrate that adversarial examples extend beyond laboratory settings and pose a credible,
concrete, low-cost threat to driving safety.
The NECSTLab is a DEIB laboratory, with different research lines on advanced topics in computing systems: from architectural characteristics, to hardware-software codesign methodologies, to security and dependability issues of complex system architectures.
