Privately Connecting Mobility to Infectious Diseases via Applied Cryptography

This repository contains the source code of the paper [1,2] by researchers of TU Graz. A current version of the paper is also present in this repository. For more information on the project, visit https://covid-heatmap.iaik.tugraz.at/.

Source code

The code is based on Microsoft SEAL (https://github.com/Microsoft/SEAL) and is compatible with Windows and Linux. This repository contains a demo application to perform the matrix multiplication on encrypted data and to compute the challenge mask. Use params.h for a parametrization of the code.

Compilation:

Execute the following commands to compile the source code:

git submodule update --init
cd SEAL
cmake .
make
cd ..
mkdir build
