Implementation of a web-based data collection and aggregation infrastructure that utilizes secure multi-party computation techniques to allow individual contributors to submit their data without revealing it to the other participants.
It is expected that this application will operate on an Amazon Web Services EC2 instance running Amazon Linux under a security group that permits connections on port 80. The environment in which it runs is set up as follows.
- First, install Node.js, MongoDB, and necessary modules:
yum -y update
yum -y install nodejs npm --enablerepo=epel
echo "[MongoDB]
name=MongoDB Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
enabled=1" | sudo tee -a /etc/yum.repos.d/mongodb.repo
yum install -y gcc-c++ mongodb-org-server mongodb-org-shell mongodb-org-tools
- Navigate to the "server/" directory and install the NPM dependencies:
npm install
- Now install the global dependency
npm install -g forever
- Next, set up the database file and start the MongoDB server:
mkdir -p /data/db
mongod
- Finally, retrieve the application files and in the directory "server/" run:
forever -o log.txt -e error.txt start index.js
