This paper gave a short overview over existing issues in the area of privacy for WWW users. It demonstrated that it is possible to increase the protection of privacy of users without adding new technologies on the client side. Rather, it demonstrated and explained a system that enhances Web servers. This system is capable of modifying URLs in HTML documents is such a way that it is only possible for the same user to retrieve the according documents.

The authors are aware that this system doesn't provide perfect protection for users. For example, it might still be possible to create tools that manipulate Web browsers directly to get access to the content of a retrieved document.

On the other hand, the proposed system is one more step to protect users from being kept under surveillance. Therefore, the authors would like to encourage web site administrators to use the proposed system to offer their users more security.
