BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
The goal of Cheix USB is a Linux image executing from a USB storage device into a running OS, either Linux or Windows, so that the host machine does not have to support booting from the USB device. The root filesystem and boot partitions are read-only to preserve the USB device. All writes are done in a tmpfs. The only writes to the USB storage device are those explicitly made by the user. Cheix's ISO can currently be used to create either a bootable USB or a hard-drive installation.
CloudUSB is an OS package that is intended to boot from a USB stick or other mutable removable media. Its purpose is to let you carry your whole computing environment in your pocket and let you use any computer available as if it were your own. It stores your personal data in encrypted form on the same medium as the OS and in an online storage space, thus granting you security and privacy. Local and remote data are synchronized, allowing work to continue even offline. CloudUSB currently uses Ubuntu as the OS and Dropbox as the online storage service.
Coquelicot is a “one-click” file sharing Web application with a focus on protecting users’ privacy. Its basic principle is that users can upload a file to the server, and in return they get a unique URL which can be shared with others in order to download the file. Coquelicot aims to protect, to some extent, users and system administrators from disclosure of the files exchanged from passive and not-so-active attackers.
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.
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.
HeaderCleaner is a small SMTP server plugin that will only allow a set of predefined headers in an outgoing email message and will strip all other headers from the message. This is meant to improve your privacy and better protect the mail handling server. This version is made for Communigate-Pro, but can be adapted for other systems.
