Text-to-image diffusion models, e.g. Stable Diffusion (SD), lately have shown remarkable ability in high-quality content generation, and become one of the representatives for the recent wave of transformative AI. Nevertheless, such advance comes with an intensifying concern about the misuse of this generative technology, especially for producing copyrighted or NSFW (i.e. not safe for work) images. Although efforts have been made to filter inappropriate images/prompts or remove undesirable concepts/styles via model fine-tuning, the reliability of these safety mechanisms against diversified problematic prompts remains largely unexplored. In this work, we propose Prompting4Debugging (P4D) as a debugging and red-teaming tool that automatically finds problematic prompts for diffusion models to test the reliability of a deployed safety mechanism. We demonstrate the efficacy of our P4D tool in uncovering new vulnerabilities of SD models with safety mechanisms. Particularly, our result shows that around half of prompts in existing safe prompting benchmarks which were originally considered ``safe'' can actually be manipulated to bypass many deployed safety mechanisms, including concept removal, negative prompt, and safety guidance. Our findings suggest that, without comprehensive testing, the evaluations on limited safe prompting benchmarks can lead to a false sense of safety for text-to-image models.

Installation

conda create -n diffusion python=3.10
conda activate diffusion
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113
pip install -r requirements.txt

Change the torch version according to your CUDA version. See here for more details.

Dataset Setup

Data use in our experiments can be find in data/.

You can also make your own ideal dataset for debugging as follow:

python process_data.py \
    --save-prompts custom_ideal_data.csv \
    --prompts-csv [ORIGINAL_PROMPT].csv \
    --erase-id [SAFE_T2I] \
    --category [CONCEPT] \
    --config ./configs/[SAFE_T2I]_nudity_optmz.json

• Input (--prompts-csv): original prompt dataset, refer to CSV files in data/ for format
• Output (--save-prompts): processed ideal prompts for debugging
• erase-id: esd, sld or sd
• --category: nudity -> ask us for more categories
• --safe-level: only defined if you use sld -> MAX, STRONG, MEDIUM, WEAK
• --config: configuration file for the safe T2I model

Prompt Optimization

P4D-N

python run_p4dn.py \
    --config ./configs/esd_nudity_optmz_config.json \
    --data ./data/unsafe-prompts-nudity_esd.csv \
    --save-prompts ./esd_nudity_optmz.csv \
    --nudenet-path ./pretrained/nudenet_classifier_model.onnx \
    --category nudity \
    --erase-id esd \
    --device cuda:x \
    --device-2 cuda:y

P4D-K

python run_p4dk.py \
    --config ./configs/esd_nudity_optmz_config.json \
    --data ./data/unsafe-prompts-nudity_esd.csv \
    --save-prompts ./esd_nudity_optmz.csv \
    --nudenet-path ./pretrained/nudenet_classifier_model.onnx \
    --category nudity \
    --erase-id esd \
    --device cuda:x \
    --device-2 cuda:y

• Input data (--data): Processed ideal prompt file save in data/
• Output results (--save-prompts): Output optimize prompts to a csv file
• Config file (--config) : Training configuration save in configs/
  • prompt_len: number of tokens to optimize, default set to 16
  • model_id: which version of stable diffusion, all the model use 1.4 except SD with negative prompt use 2.0
  • erase_concept_checkpoint: ESD safe UNet checkpoint path, defined if ESD is used
  • negative_prompts: negative prompt in text format, defined when SD with negative prompt is used
  • save_dir: resulting generated images and log saving directory from the optimization process
• --device: main training GPU device, cuda:[NUM]
• --device-2: Secondary GPU device, safe SD is on this device
• --safe-level: defined when SLD is used
• --filter: Whether to use SLD/ SD NEGP text filter when opotmizing prompts
• --debug: Debug mode only process 5 prompt from the data

ESD UNet checkpoints can be download from:
