An Efficient Membership Inference Attack for the Diffusion Model by Proximal Initialization

Official repo for An Efficient Membership Inference Attack for the Diffusion Model by Proximal Initialization.

Requirements

Follow gradtts/train/README.md.

DDPM

train DDPM model

We provide the split of the dataset. They are DDPM/CIFAR10_train_ratio0.5.npz and DDPM/TINY-IN_train_ratio0.5.npz. To train the DDPM, you need put the cifar10 dataset into DDPM/data/pytorch and Tiny-ImageNet to DDPM/data/tiny-imagenet-200. You can also change the directory by modifying the path in main.get_dataset function and dataset_utils.load_member_data. You can change the log directory by modifying FLAGS.logdir in main.py. You can change the FLAGS.dataset to select the dataset.

Then, to train the DDPM, just run command below.

cd DDPM
python main.py

attack DDPM model

Just run command below.

cd DDPM
python attack.py --checkpoint your_checkpoint --dataset your_dataset --attacker_name attacker_name --attack_num attack_num --interval interval

The meaning of those parameters:

--checkpoint The checkpoint you saved.

--dataset The dataset to attack. It can be cifar10 or TINY-IN.

--attacker_name The attack method. naive for NA in our paper. SecMI for SceMI attack. PIA for PIA and PIAN for PIAN

--attack_num attack number from $t=0$

--interval attack interval. For example, if attack_num=5, interval=20, the attack method will attack [20, 40, 60, 80, 100].

At last, this program will print AUC and TPR @ 1% FPR in [20, 40, 60, 80, 100].

apply our method to other model

Inherit a subclass from components.EpsGetter, implement __call__ method, and return predicted $\epsilon$. noise_level[t] is $\prod_{k=1}^{t} (1-\beta_k)$. Keep other same with attack.py.

GradTTS

train GradTTS model

Code in gradtts/train is the official code of gradtts. We provide the dataset split in gradtts/train/split. Just put LJSpeech and LibriTTS into gradtts/train/datasets. For LibriTTS, to use our pretrained checkpoint, your need to resample audio to 22050Hz. Run command below to resample:

cd gradtts/train
python resample.py

To train the model, your can chagne parameters in gradtts/train/params.py for ljspeech and gradtts/train/params_libritts.py for libritts, especially for train_filelist_path, valid_filelist_path and log_dir. By default, without any change, code can work properly.

cd gradtts/train
python train.py   # for ljspeech
python train_multi_speaker_libritts.py  # for libritts

attack Stable Diffusion

Just run command below.

cd stable_diffusion
python attack.py --checkpoint your_checkpoint --dataset your_dataset --attacker_name attacker_name --attack_num attack_num --interval interval

The meaning of those parameters:

--checkpoint The checkpoint you saved.

--dataset The dataset to attack. It can be laion5, laion5_none (no groundtruth text) or laion5_blip (blip generated text).

--attacker_name The attack method. naive for NA in our paper. SecMI for SceMI attack. PIA for PIA and PIAN for PIAN

--attack_num attack number from $t=0$

--interval attack interval. For example, if attack_num=5, interval=20, the attack method will attack [20, 40, 60, 80, 100].

At last, this program will print AUC and TPR @ 1% FPR in [20, 40, 60, 80, 100].

You to attack stable diffusion, you need to install diffusers==0.18.0.

We also provide the images evaluated in our paper. Download from MIA_efficient. If you download the data, you could modify /home/kongfei/workspace/PIA/stable_diffusion/dataset.py and set up coco_dataset_root, coco_dataset_anno and stable_diffusion_data. The you also need to download COCO dataset by yourself.

attack GradTTS

Change the value of train_filelist_path, valid_filelist_path in gradtts/attack/gradtts/params_ljspeech.py and gradtts/attack/gradtts/params_libritts.py to load dataset.

cd gradtts/attack
python attack.py --checkpoint your_checkpoint --dataset your_dataset --attacker_name attacker_name --attack_num attack_num --interval interval

The meaning of parameters is same with that in DDPM.

--dataset You can use ljspeech or libritts.

Pretrained Checkpoint

You can download pretrained checkpoint from MIA_efficient.
