With ParTCP Vote you can easily take part in votes that were created on a ParTCP server. Password protection prevents other people from voting on your behalf or finding out how you voted. If you share your device with other people, each person can create their own protected area.
ParTCP is a platform on which secret, tamper-proof voting can be carried out. All components are open source and can be used freely. Any PHP-enabled web server can serve as a voting server and no data will be passed on to third parties.
