People who live in countries where the internet is censored need "bridges." These lead to the known entry nodes to the Tor network, which are usually blocked by the regimes.Įvery Tor user can provide a bridge, making their own machine a virtual entry point. How do I get into the Tor network from a country with censorship? Because the server then responds differently, however, the regime will probably disconnect you. If the traffic is disguised as a video conference, they can see whether the server is also responding like a video conference server. If the censorship authorities suspect that they are seeing Tor traffic veiled by a pluggable transport, they may send their own traffic to see how the server responds.
The countries with the most secure serversĬan censorship authorities outwit pluggable transports? This makes it more difficult for censors to follow the surfing process. It also changes back and forth all the time. For example, if someone surfs websites, it may look like a video conference, normal email traffic or something else. To circumvent censorship, Tor has developed so-called "pluggable transports." These make internet traffic appear completely different than it really is. So you can't tell who I am, but you can tell what I'm doing?Ī censor can recognize what the internet traffic basically looks like, but can't necessarily glean any information from it. More on the topic you can find on the special DW-page Censored Net.
At that moment, you leave the Tor network and anonymity is somewhat limited, but the operator of the website that you are visiting cannot recognize either your IP address or any unique features of your browser, because Tor suppresses this information. However, you can also access all other normal websites with the Tor browser. Deutsche Welle also provides such a service. There are special Tor websites with so-called onion services. This makes surfing very secure.Ĭan I access all web pages with the Tor browser? Instead, Tor connects you using detours: so-called Tor nodes.Įach of these Tor nodes lays its own encryption layer over the browser behavior so that the other Tor nodes can't read it, either. You are not directly connected to the server from which you want to retrieve information by the shortest route. Tor means "The Onion Router." It's built like an onion - in layers. So you have to come up with something new, such as the Tor network. Moreover, proxies do not offer anonymity. Today, censorship regimes have become much more attentive and block static proxies relatively quickly. But censorship authorities can see that it is a VPN connection and who operates it.

The tunnel can also be used to access the free internet from a censored area. With VPNs, companies do things like establish a secure connection between their employees and the internal company network. To do make use of them, you set up an encrypted tunnel connection to a server, for example in another country. Virtual private networks (VPN) are somewhat more complex.

For this, you can take the detour via Anonymouse or a variety of similar anonymization services. Proxies can also be used to conceal from the operators of websites where a visit is coming from. In the meantime, however, many states have begun to block all proxies they disapprove of.
This worked as long as the censors didn't notice or know the proxies. Often, it was just simple IP addresses that forwarded internet traffic. In the past, only static proxies were used. If a regime blocks certain websites, how can I still access them? Very precise user fingerprints can be created that make someone recognizable to a web server to 98%, even without an IP address. But nowadays, users are also often recognized by other data from their computers: unique properties of browser plugins, screen resolution, window size, language, time. First, there is the IP address of your computer. How do I become visible to others on the internet?īasically, all internet traffic is visible to everyone who has access to the servers through which it flows - just as a postcard can be read by any mail carrier.Ī lot of data can reveal your identity.
