Cloak of Invisibility: Real-Time Privacy-Preserving Volumetric Video Streaming
Hossein Khalili, Philip Do, Alexander Vilesov +3
Volumetric video streaming turns privacy into a 3D, multi-view problem. Unlike ordinary video, where sensitive content can often be redacted frame by frame, RGB-D volumetric pipeli…
Defense Against Prompt Inversion Attacks: An Information-Theoretic Approach for LLM Collaborative Inference
Sayedeh Leila Noorbakhsh, Hossein Khalili, Nader Sehatbakhsh
Collaborative edge-cloud inference enables resource-constrained devices to leverage large language models (LLMs) by offloading partial computation to cloud servers. However, transm…
To See or Not to See -- Fingerprinting Devices in Adversarial Environments Amid Advanced Machine Learning
Justin Feng, Amirmohammad Haddad, Nader Sehatbakhsh
The increasing use of the Internet of Things raises security concerns. To address this, device fingerprinting is often employed to authenticate devices, detect adversaries, and ide…
SuperPure: Efficient Purification of Localized and Distributed Adversarial Patches via Super-Resolution GAN Models
Hossein Khalili, Seongbin Park, Venkat Bollapragada +1
As vision-based machine learning models are increasingly integrated into autonomous and cyber-physical systems, concerns about (physical) adversarial patch attacks are growing. Whi…
