Whonix is an anonymous general-purpose operating system based on Virtual Box, Debian GNU/Linux, and Tor. By design, IP and DNS leaks are impossible. Not even malware with root rights can find out the user's real IP/location, because Whonix consists of two (virtual) machines. One machine solely runs Tor and acts as a gateway, called Whonix-Gateway. The other machine, Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible.
Fluxfont is a specialized tool that attempts to tackle the privacy concerns raised by the possibility to collect information about the fonts installed on a system. Such information can be used to uniquely identify a system. With Fluxfonts, new fonts are randomly created and removed to prevent the same fingerprint from being recreated.
GTK+ Recent Files Scrubber is a compact, lightweight Python script which uses GTK's RecentManager to watch for updates to all globally-available "Recently Used" lists (the ones which appear in Open dialogs and the like) and filter out anything in the folders you blacklist. Blacklist entries are hashed to make reading the blacklist not worth the effort.
The Dynamic Router Lite II project is a router project by the Dutch national police agency that allows Web-based client-control over the next-hop router for the client. A Dynamic Router Lite II system is placed as a default gateway between one or more client networks and a router network with multiple gateway-routers on it. The Dynamic Router Lite II system does policy-based routing with policy-based DNS to match the routing policy. By default a client will have no active gateway, and any attempted HTTP traffic to any domain will lead the user to the router's Web interface, where the user can then pick an appropriate next-hop router. Once picked, all traffic for the client including DNS will be forwarded to the next-hop router the user picked.
