Abstract: The Data Traffic Controller is a system and method that provides users with the ability to view, control and protect themselves during their online browsing. Most websites come with an array of tracking elements and third-party content which could be unknown or misleading to the user. The Data Traffic Controller interface embraces member functions, events, and properties. The member functions provide high level services such as Proxy, VPN, filter inappropriate content, block or allow certain websites, detect and block trackers, and control browser behavior which includes cookies and history retention. The Data Traffic Controller displays notifications and statistics as it encounters events. It also represents all the tracking and third-party activity and their connectedness using a graph, where the user has the ability to further control individual elements.
