Anonymity Test

What can a web site find out about you? And is that proxy you found fully anonymous? Step in here and find out. Unlike the standard "show my IP" pages out there, this script also looks at a whole range of little known header variables that some proxies use to transmit your real IP address.

Link Anonymizer

This is a handy little tool that let you link to any web site without it being able to record the referrer URL. You can use it directly by linking in this format: http://prot.com/?http://whateverhere.com, but you can also encrypt your link so that the link destination itself is also anonymous.

OpenID Anonymity

More and more sites are becoming OpenID-enabled, allowing visitors to log in using their profile at an OpenID provider as log-in credentials. But if you don't want to give up your blogger or AOL identity to a site, use this anonymous, automatic OpenID authenticator.
