Meet SilentKeys: a smart keyboard with a switch that lets you encrypt your online connection to protect your privacy. It supports VPN and Tor to keep you anonymous. The keyboard can also protect you against keyloggers, viruses, and other threats. It is based on an open source solution.
SilentKeys is easy to use. Simply plug it in, press the button, and choose your level of privacy. The rest is easy. Yet another interesting Kickstarter project.
