Tracking Web Fingerprints

The Electronic Frontier Foundation has discovered a new way for Web hosts to track user’s movements around the Internet without using cookies or IP addresses. Each web page request that arrives at a server contains detailed information about the user’s computer such as browser type and version, and the plugins that are installed. That information can be compiled to create a unique fingerprint for most computers. Computer fingerprints can be used to compile information about a user’s interests and habits which are valuable commodities for Internet advertisers.
