Abstract

With the rapid progress of generation technology, it has become necessary to attribute the origin of fake images. Existing works on fake image attribution perform multi-class classification on several Generative Adversarial Network (GAN) models and obtain high accuracies. While encouraging, these works are restricted to model-level attribution, only capable of handling images generated by seen models with a specific seed, loss and dataset, which is limited in real-world scenarios. In this work:

• We present the first study on Deepfake Network Architecture Attribution to attribute fake images on architecture-level.
  
• We develop a simple yet effective approach named DNA-Det to extract architecture traces, which adopts pre-training on image transformation classification and patchwise contrastive learning to capture globally consistent features that are invariant to semantics.
  
• The evaluations on multiple cross-test setups and a large-scale dataset verify the effectiveness of DNA-Det. DNA-Det maintains a significantly higher accuracy than existing methods in cross-seed, cross-loss, cross-finetune and cross-dataset settings.

Prerequisites

• Linux
• NVIDIA GPU + CUDA 11.1
• Python 3.7.10

Data preparation

• Download dataset, and put it into the directory ./dataset.
• Download the train part of CNNDetection dataset, and put it into the directory ./dataset/GANs.
• Prepare annotation files for training, validation, closed-set testing and cross testings.
  • Prepare dataset for the celebA experiment.

  python generate_data_multiple_cross.py --mode celeba
  

  • Prepare dataset for the LSUN-bedroom experiment.

  python generate_data_multiple_cross.py --mode lsun
  

  • Prepare dataset for the in the wild experiment.

  python generate_data_in_the_wild.py --mode in_the_wild
  

  After generation, the folder should be like this:

  dataset
  ├── ${mode}_test
  │   └── annotations
  │       ├── ${mode}_test.txt
  │       ├── ${mode}_test_cross_seed.txt
  │       ├── ${mode}_test_cross_loss.txt
  │       ├── ${mode}_test_cross_finetune.txt
  │       └── ${mode}_test_cross_dataset.txt
  ├── ${mode}_train
  │   └── annotations
  │       └── ${mode}_train.txt
  └── ${mode}_val
      └── annotations
          └── ${mode}_val.txt
  

  where {mode}_train.txt, {mode}_val.txt, {mode}_test.txt, {mode}_test_cross_*.txt are the annotation files for training, validation, closed-set testing and cross testing spilts.
• Quick implement: We provide generated txt files, they can be downloaded from Baiduyun(passwd:olci) or GoogleDrive. Put them into the directory ./dataset.

Pretrain on Image Transformations

sh ./script/run_train_pretrain.sh

After training, the model and logs are saved in ./dataset/pretrain_train/models/pretrain_val/pretrain/run_${run_id}/.

Training

1. Specify training configurations in ./configs/${config_name}.py
   
2. Specify settings including config_name, data_path and so on in ./script/run_train.sh and run:

sh ./script/run_train.sh

• Following is an example for celebA experiment:

data_path=./dataset/
train_collection=celeba_train
val_collection=celeba_val
config_name=celeba
run_id=1
pretrain_model_path=./dataset/pretrain_train/models/model.pth
python main.py  --data_path $data_path --train_collection $train_collection --val_collection $val_collection \
--config_name $config_name --run_id $run_id \
--pretrain_model_path $pretrain_model_path 

where

• data_path: The dataset path
• train_collection: The training split directory
• val_collection: The validation split directory
• config_name: The config file
• run_id: The running id for numbering this training
• pretrain_model_path: The pretrain model on image transformation classification

Similarly, for the LSUN-bedroom experiment:

data_path=./dataset/
train_collection=lsun_train
val_collection=lsun_val
config_name=lsun
run_id=1
pretrain_model_path=./datasets/pretrain_train/models/pretrain_val/pretrain/run_0/model.pth
python main.py  --data_path $data_path --train_collection $train_collection --val_collection $val_collection \
--config_name $config_name --run_id $run_id \
--pretrain_model_path $pretrain_model_path 

For the in the wild experiment:

data_path=./dataset/
train_collection=in_the_wild_train
val_collection=in_the_wild_val
config_name=in_the_wild
run_id=1
pretrain_model_path=./datasets/pretrain_train/models/pretrain_val/pretrain/run_0/model.pth
python main.py  --data_path $data_path --train_collection $train_collection --val_collection $val_collection \
--config_name $config_name --run_id $run_id \
--pretrain_model_path $pretrain_model_path 

3. After training, the models and logs are saved in ./${data_path}/${train_collection}$/models/${val_collection}/${config_name}/run_${run_id}/.

Pre-trained models

We provide pre-trained models: Baiduyun(passwd:olci) or GoogleDrive. They have been put into the right path along with the annotation files. See model_path in ./script/run_test.sh.

Inference

To evaluate the trained model on multiple cross-test setups. Specify settings in ./script/run_test.sh and run:

sh ./script/run_test.sh

• Following is an example for the celebA experiment:

config_name=celeba
model_path=./dataset/celeba_train/models/celeba_val/celeba/run_0/model.pth
python3 pred_eval.py --model_path $model_path --config_name $config_name \
--test_data_paths \  
./dataset/celeba_test/annotations/celeba_test.txt \
./dataset/celeba_test/annotations/celeba_test_cross_seed.txt \
./dataset/celeba_test/annotations/celeba_test_cross_loss.txt \
./dataset/celeba_test/annotations/celeba_test_cross_finetune.txt \
./dataset/celeba_test/annotations/celeba_test_cross_dataset.txt  

• Following is an example for the LSUN-bedroom experiment:

config_name=lsun
model_path=./dataset/lsun_train/models/lsun_val/lsun/run_0/model.pth
python3 pred_eval.py --model_path $model_path --config_name $config_name \
--test_data_paths \  
./dataset/lsun_test/annotations/lsun_test.txt \
./dataset/lsun_test/annotations/lsun_test_cross_seed.txt \
./dataset/lsun_test/annotations/lsun_test_cross_loss.txt \
./dataset/lsun_test/annotations/lsun_test_cross_finetune.txt \
./dataset/lsun_test/annotations/lsun_test_cross_dataset.txt  

• Following is an example for the in the wild experiment:

config_name=in_the_wild
model_path=./dataset/in_the_wild_train/models/in_the_wild_val/in_the_wild/run_0/model.pth
python3 pred_eval.py --model_path $model_path --config_name $config_name \
--test_data_paths \  
./dataset/in_the_wild_test/annotations/in_the_wild_test.txt \
./dataset/in_the_wild_test/annotations/in_the_wild_test_cross_dataset.txt  

After running, the result will be saved in ./${test_data_path}/pred/result.txt
