Backdooring Textual Inversion for Concept Censorship

no code implementations21 Aug 2023 Yutong Wu, Jie Zhang, Florian Kerschbaum, Tianwei Zhang

Users can easily download the word embedding from public websites like Civitai and add it to their own stable diffusion model without fine-tuning for personalization.

Personalization as a Shortcut for Few-Shot Backdoor Attack against Text-to-Image Diffusion Models

no code implementations18 May 2023 Yihao Huang, Felix Juefei-Xu, Qing Guo, Jie Zhang, Yutong Wu, Ming Hu, Tianlin Li, Geguang Pu, Yang Liu

Although recent personalization methods have democratized high-resolution image synthesis by enabling swift concept acquisition with minimal examples and lightweight computation, they also present an exploitable avenue for high accessible backdoor attacks.

Watermarking Pre-trained Encoders in Contrastive Learning

no code implementations20 Jan 2022 Yutong Wu, Han Qiu, Tianwei Zhang, Jiwei L, Meikang Qiu

It is challenging to migrate existing watermarking techniques from the classification tasks to the contrastive learning scenario, as the owner of the encoder lacks the knowledge of the downstream tasks which will be developed from the encoder in the future.
