Quo vadis network anonymity?
The Internet promises an ever-increasing variety of services available anytime, almost anywhere, to anyone of just about any experience level. Thus, in many respects, the virtual world has become a viable alternative to our real world, where we can buy anything from a dishwasher to personal services, or publish any information we choose on a personal web site.

If they choose, they can study in absolute solitude or meet with others in private rooms, or they can anonymously buy a magazine. However, on the Internet, users have few controls, if any, over the privacy of their actions.
