### Example
|
||||
|
||||
`fawkes -d ./imgs --mode min`
|
||||
`fawkes -d ./imgs --mode low`
|
||||
|
||||
or `python3 protection.py -d ./imgs --mode low`
|
||||
|
||||
|
||||
### Tips
|
||||
- The perturbation generation takes ~60 seconds per image on a CPU machine, and it would be much faster on a GPU machine. Use `batch-size=1` on CPU and `batch-size>1` on GPUs.
|
||||
- Turn on separate target if the images in the directory belong to different people, otherwise, turn it off.
|
||||
- Run on GPU. The current Fawkes package and binary does not support GPU. To use GPU, you need to clone this, install the required packages in `setup.py`, and replace tensorflow with tensorflow-gpu. Then you can run Fawkes by `python3 fawkes/protection.py [args]`.

We are actively working on this. Python scripts that can test the protection effectiveness will be ready shortly.

Academic Research Usage
|
||||
-----------------------
|
||||
For academic researchers, whether seeking to improve fawkes or to explore potential vunerability, please refer to the following guide to test Fawkes.
|
||||
|
||||
To protect a class in a dataset, first move the label's image to a seperate location and run Fawkes. Please use `--debug` option and set `batch-size` to a reasonable number (i.e 16, 32). If the images are already cropped and aligned, then also use the `no-align` option.

# Fawkes Binary
|
||||
|
||||
This application is built for individuals to cloak their images before uploading to the Internet. For more information about the project, please refer to our project [webpage](http://sandlab.cs.uchicago.edu/fawkes/).
|
||||
|
||||
If you are a developer or researcher planning to customize and modify on our existing code. Please refer to [fawkes](https://github.com/Shawn-Shan/fawkes/tree/master/).
|
||||
|
||||
### How to Setup
|
||||
|
||||
#### MAC:
|
||||
|
||||
* Create a directory and move all the images you wish to protect into that directory. Note the path to that directory (e.g. ~/Desktop/images).
|
||||
* Open [terminal](https://support.apple.com/guide/terminal/open-or-quit-terminal-apd5265185d-f365-44cb-8b09-71a064a42125/mac) and change directory to fawkes (the unzipped folder).
|
||||
* (If your MacOS is Catalina) Run `sudo spctl --master-disable` to enable running apps from unidentified developer. We are working on a solution to bypass this step.
|
||||
* Run `./protection-v0.3 -d IMAGE_DIR_PATH` to generate cloak for images in `IMAGE_DIR_PATH`.
|
||||
* When the cloaked image is generated, it will output a `*_min_cloaked.png` image in `IMAGE_DIR_PATH`. The generation takes ~40 seconds per image depending on the hardware.
|
||||
|
||||
|
||||
#### PC:
|
||||
* Create a directory and move all the images you wish to protect into that directory. Note the path to that directory (e.g. ~/Desktop/images).
|
||||
* Open terminal(powershell or cmd) and change directory to protection (the unzipped folder).
|
||||
* Run `protection-v0.3.exe -d IMAGE_DIR_PATH` to generate cloak for images in `IMAGE_DIR_PATH`.
|
||||
* When the cloaked image is generated, it will output a `*_min_cloaked.png` image in `IMAGE_DIR_PATH`. The generation takes ~40 seconds per image depending on the hardware.
|
||||
|
||||
#### Linux:
|
||||
* Create a directory and move all the images you wish to protect into that directory. Note the path to that directory (e.g. ~/Desktop/images).
|
||||
* Open terminal and change directory to protection (the unzipped folder).
|
||||
* Run `./protection-v0.3 -d IMAGE_DIR_PATH` to generate cloak for images in `IMAGE_DIR_PATH`.
|
||||
* When the cloaked image is generated, it will output a `*_min_cloaked.png` image in `IMAGE_DIR_PATH`. The generation takes ~40 seconds per image depending on the hardware.
