The goal of Ubuntu Privacy Remix is to provide an isolated working environment where sensitive data can be dealt with safely. The system installed on the computer running UPR remains untouched, UPR is not intended for permanent installation on hard disk. Instead of that Ubuntu Privacy Remix runs from a modified Live-CD based on Ubuntu Linux. All user data reside exclusively on encrypted removable media.
Ubuntu Privacy Remix is a tool to protect your data against unsolicited access. The
risk of theft of such private data arises not only from "conventional"
criminals, trojans. rootkits, keyloggers etc. In many countries,
measures are taken by the state aiming at spying and monitoring
But I am already encrypting my data...
encryption is of course one of the most important measures to protect
your data. Ubuntu Privacy Remix contains the well-known cryptographis
software TrueCrypt and GnuPG. But the security of encryption relies not
only on the security of the used software.
Trojans, Rootkits, Keyloggers can lower or even circumvent the security of cryptographic software.
base idea is to relocate working with private data into a secure
working environment, strictly apart from everything else you do with
your computer (surf the web, chat, games, ...)."
For example software like Microsoft Office or Google Desktop, which can create an unencrypted copy of the data on hard disk when opening files from an encrypted TrueCrypt-Volume.
a trojan horse waits for you to open a TrueCrypt-Container, mailing your
sensitive files to someone else at the next opportuinity.
malicious software logs your keystrokes, including the passphrase
for your secret GPG-Key, and mails it along with the key to some
unknown attacker. He could then read all your past and future
Mails he gets his hands on.
Security is a system
examples show that security means the security of the whole working
environment, and that security can never be provided by one program
alone. Editing, de- and encryption of sensitive data should therefore
be done with a system that
- never has or had contact to untrustworthy networks like the internet
- cannot leave data unencrypted on the hard drive, not even unnoticed or by accident
- offers no opportunity to spyware to permanently install onto the system
Ubuntu Privacy Remix creates such a working environment on any PC with the following measures:
