CSGuard: Toward Forgery-Resistant Watermarking in Diffusion Models via Compressed Sensing Constraint
Jiewei Lai, Lan Zhang, Chen Tang +4
Latent-based diffusion model watermarking embeds watermarks into generated images' latent space to enable content attribution, offering a training-free solution for intellectual pr…
Activation-Space Anchored Access Control for Multi-Class Permission Reasoning in Large Language Models
Zhaopeng Zhang, Pengcheng Sun, Lan Zhang +4
Large language models (LLMs) are increasingly deployed over knowledge bases for efficient knowledge retrieval and question answering. However, LLMs can inadvertently answer beyond…
Untraceable DeepFakes via Traceable Fingerprint Elimination
Jiewei Lai, Lan Zhang, Chen Tang +3
Recent advancements in DeepFakes attribution technologies have significantly enhanced forensic capabilities, enabling the extraction of traces left by generative models (GMs) in im…
DERMARK: A Dynamic, Efficient and Robust Multi-bit Watermark for Large Language Models
Qihao Lin, Chen Tang, Lan zhang +2
As large language models (LLMs) grow more powerful, concerns over copyright infringement of LLM-generated texts have intensified. LLM watermarking has been proposed to trace unauth…
Efficient and Accurate Image Provenance Analysis: A Scalable Pipeline for Large-scale Images
Jiewei Lai, Lan Zhang, Chen Tang +1
The rapid proliferation of modified images on social networks that are driven by widely accessible editing tools demands robust forensic tools for digital governance. Image provena…
