The operating system will only boot from CD which means that its data cannot be altered by malware or other forms of malicious software. It furthermore ignores local hard drives completely so that no data can be read or written to those storage devices.

A modified system kernel ensures that no network hardware can be activated which means that there is no possibility for connections to the Internet, local area network or other types of external connections. The only way to work with data is by using extended True-Crypt volumes which can be used to save system configurations and user data. (read working with extended True-Crypt volumes for additional information)

The Ubuntu Privacy Remix Live CD can be downloaded directly from the project’s homepage. The disk ISO image has a size of 688 Megabytes and has to be burned to CD after the download. A GnuPG signatur is available for verification.
