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 a very performant combinations of the two. Also, check the main demonstration from the Sonar project.

Local setup

Prerequisites

• Make sure Python 3.5+ in installed on your machine by checking python3 --version
• Set up a virtual environment for the Python libraries (optional, recommended)
• Install our OpenMined Unity app by following the guidelines here

Python Requirements

The Python dependencies are listed in requirements.txt and can be installed through

pip3 install -r requirements.txt

PySyft installation

If you simply want to to use PySyft, it is enough to install the library with:

python3 setup.py install

note: If you have anaconda installed, you can just run bash install_for_anaconda.sh.
