At a hacker conference in Washington last week a new search concept was unveiled that will enable personal anonymity to be protected. It is called Anonym.OS. Apparently not viable on a large scale for a variety of reasons, it is nevertheless expected to lead to a system whereby you will carry a USB key with you that can be used wherever you are - on your own laptop or in a cyber cafe - to ensure that neither you nor the computer you use will be able to be tracked in the way that Google and others currently track your every move.
