Abusing Images and Sounds for Indirect Instruction Injection in Multi-Modal LLMs

1 code implementation19 Jul 2023 Eugene Bagdasaryan, Tsung-Yin Hsieh, Ben Nassi, Vitaly Shmatikov

We demonstrate how images and sounds can be used for indirect prompt and instruction injection in multi-modal LLMs.

Seeds Don't Lie: An Adaptive Watermarking Framework for Computer Vision Models

no code implementations24 Nov 2022 Jacob Shams, Ben Nassi, Ikuya Morikawa, Toshiya Shimizu, Asaf Shabtai, Yuval Elovici

In this paper, we present an adaptive framework to watermark a protected model, leveraging the unique behavior present in the model due to a unique random seed initialized during the model training.
