GAN IPR Protection

Official pytorch implementation of the paper: "Protecting Intellectual Property of Generative Adversarial Networks from Ambiguity Attack"

CVPR 2021

Updated on November 9, 2021

Description

Ever since Machine Learning as a Service (MLaaS) emerges as a viable business that utilizes deep learning models to generate lucrative revenue, Intellectual Property Right (IPR) has become a major concern because these deep learning models can easily be replicated, shared, and re-distributed by any unauthorized third parties. To the best of our knowledge, one of the prominent deep learning models - Generative Adversarial Networks (GANs) which has been widely used to create photorealistic image are totally unprotected despite the existence of pioneering IPR protection methodology for Convolutional Neural Networks (CNNs). This paper therefore presents a complete protection framework in both black-box and white-box settings to enforce IPR protection on GANs. Empirically, we show that the proposed method does not compromise the original GANs performance (i.e. image generation, image super-resolution, style transfer), and at the same time, it is able to withstand both removal and ambiguity attacks against embedded watermarks.

How to run

The code is tested on Python 3.8.8 and PyTorch 1.8.0.

Dependencies

$ pip install -r requirements.txt

Train

Modify the config files in configs/, then run the following command:

$ python train.py -c configs/<path-to-yaml-file>

Tensorboard

$ tensorboard --logdir log/

Evaluate

$ python eval.py -l log/<directory> -s sample/

To evaluate CycleGAN on CityScapes, you can use the code in scripts/. You need to rename the trained log directory log/CycleGAN-XXXX-CITY-X to scripts/log and run run.py. Next, you need to download the fcn-8s-cityscapes.caffemodel and put it in scripts/caffemodel directory (Please see the original CycleGAN repo). Finally, you should put the cityscapes ground-truth images in scripts/gt/. The file structure should be as shown below:

scripts/
├─ caffemodel/
│  ├─ deploy.prototxt
│  └─ fcn-8s-cityscapes.caffemodel
├─ gt/
│  ├─ 1.png
│  ├─ ...
│  └─ 499.png
├─ log/
│  ├─ samples
│  │  ├─ 1.png
│  │  ├─ ...
│  │  └─ 499.png
│  ├─ metrics.json
│  └─ ...
├─ Dockerfile
├─ labels.py
└─ run.py

Then, run python run.py to start the evaluation.

Attack

Fine-tuning and Overwriting

$ python attack.py -l log/<directory> -m <finetune/overwrite> -w <path-to-new-watermark> -d <to-load-discriminator>

Pruning

$ python prune.py -l log/<directory> -s sample/

Ambiguity Attack

$ python sign_flip.py -l log/<directory> -s sample/
