Syft

Homomorphically Encrypted Deep Learning Library

The goal of this library is to give the user the ability to efficiently train Deep Learning models in a homomorphically encrypted state without needing to be an expert in either. Furthermore, by understanding the characteristics of both Deep Learning and Homomorphic Encryption, we hope to find very performant combinations of the two. See notebooks folder for tutorials on how to use the library.

Installation

You need to install this library locally before running any of the notebooks this repository or the main demonstration:

# Get dependencies ready
pip install -r requirements.txt
# install the lib locally
python setup.py install

For Anaconda Users:

bash install_for_anaconda_users.sh

Windows

conda install -c conda-forge gmpy2
pip install -r requirements.txt
python setup.py install

For Docker Users

Install Docker from https://www.docker.com/ For macOS users with Homebrew installed, use brew cask install docker

Then, run:

git clone https://github.com/OpenMined/PySyft.git
cd PySyft
make run
