FBPCP (Facebook Private Computation Platform)

Secure multi-party computation (also known as secure computation, multi-party computation (MPC), or privacy-preserving computation) is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private.

FBPCP (Facebook Private Computation Platform) is a secure, privacy safe and scalable architecture to deploy MPC (Multi Party Computation) applications in a distributed way on virtual private clouds. FBPCF (Facebook Private Computation Framework) is for scaling MPC computation up via threading, while FBPCP is for scaling MPC computation out via Private Scaling architecture. FBPCP consists of various services, interfaces that enable various private measurement solutions, e.g. Private Lift.

Private Scaling resembles the map/reduce architecture and is secure against a semi-honest adversary who tries to learn the inputs of the computation. The goal is to secure the intermediate output of each shard to prevent potential privacy leak.

Installation Requirements:

Prerequisites for working on Ubuntu 18.04:

An AWS account (Access Key ID, Secret Access Key) to use AWS SDK (boto3 API) in FBPCP
python >= 3.8
python3-pip

Installing prerequisites on Ubuntu 18.04:

python3.8

sudo apt-get install -y python3.8

python3-pip

sudo apt-get install -y python3-pip

Installing fbpcp

python3.8 -m pip install 'git+https://github.com/facebookresearch/fbpcp.git'
# (add --user if you don't have permission)

# Or, to install it from a local clone:
git clone https://github.com/facebookresearch/fbpcp.git
python3.8 -m pip install -e fbpcp
# (add --user if you don't have permission)

# Or, to install it from Pypi
python3.8 -m pip install fbpcp

Upgrading fbpcp

To latest version in github main branch

python3.8 -m pip uninstall fbpcp
# uninstall fbpcp first

python3.8 -m pip install 'git+https://github.com/facebookresearch/fbpcp.git'
# (add --user if you don't have permission)
# re-install fbpcp from github repository

To latest version in Pypi

python3.8 -m pip install fbpcp --upgrade
