The “Internet” only knows about the proxy, not the three clients Resources within the Internet icon (such as web servers) are only aware of the proxy server, not of the three clients behind it. The illustration below depicts network data flow when a proxy is deployed. For example, if you connect to a web proxy and then load a website, the site is only aware that it is being accessed by the proxy and it has no knowledge of your computer and IP address. However, proxies can also help protect the client user’s privacy because the target server is only aware that it is communicating with the proxy, not with the client. As such, proxies can be configured to log user activity and restrict Internet access for example, by blocking certain websites or protocols. To understand clearly how Tor functions, you must first have a good idea of what proxy servers are, and of the role they play during network transmissions.Ī proxy server acts as a middleman between a client computer and the target server or resource it is accessing. If you connect as a Tor client, your online access is channeled through this buffer before it reaches the general Internet. Tor is a system of volunteer servers that acts as a buffer between Internet users and the resources they connect to. The Onion Router ( TOR) network is intended to help protect the privacy of Internet users and promote greater freedom of expression online.
