Anonymizers
One clever approach to privacy is to use an anonymizing Web server. These are servers that are designed to act as proxies for users concerned with privacy. A user sends a URL to the anonymizer as an addition to the URL for the anonymizer itself. The software at the anonymizer then strips off the additional URL and makes a request for that URL itself. The destination server receives the request, apparently from a user on the anonymizing server. The information returned from the destination server is passed back to the anonymizer. The anonymizing site then passes this information back to the end user.
Anonymizers vary in their sophistication and their capabilities. For instance, some of the simplest anonymizers will not properly handle forms-based input for a third party. Cookies holding personal preferences are not passed along to the destination. Although this protects the privacy of the user, it may also hinder customization.
Anonymizers have trouble with active content, such as Java and ActiveX. Both of these systems for running programs on the user’s machine contain method calls that allow a running program to determine the name of the machine on which it is running. If this information is passed back to the original web server, the anonymizer is useless. Thus, if you wish to truly surf the Web anonymously through an anonymizer, you should also disable the execution of active content such as Java, JavaScript, and ActiveX.
