PrivacyShield 🛡

The idea of the privacy shield is to provide smart home owners with an interface to control their IoT devices. This interface should enable users to examine the traffic leaving the administrative domain and filter or obscure it based on protection classes. The prototype of the Privacy Shield runs on a raspberry pi 3. The pi is setup as a network bridge between the router and the IoT devices. A webserver with an React web application runs on the pi. The prototypes features include traffic analyzation and device blocking.
