ICLOAK

ICLOAK is a Linux-based operating system which is designed with security as primary objective. It boots from a live USB device, and replaces the main OS. By default, it leaves no trace on user's computer unless the files are explicitly saved on persistent partition. All internet traffic is routed through tor.

ICLOAK comes with various utilities such as word-processor ( Abiword) and spreadsheet application ( gnumeric).
