Anonymizer - Wikipedia. This article is about computer software. For the company Anonymizer, Inc., see Anonymizer (company).
An anonymizer or an anonymous proxy is a tool that attempts to make activity on the Internet untraceable. It is a proxy server computer that acts as an intermediary and privacy shield between a client computer and the rest of the Internet. It accesses the Internet on the user's behalf, protecting personal information by hiding the client computer's identifying information. Anonymizers help minimize risk. They can be used to prevent identity theft, or to protect search histories from public disclosure. Some countries apply heavy censorship on the internet. Furthermore, as information itself about Anonymizer websites are banned in these countries; users are wary that they may be falling into a government- set trap. For example, large news outlets such as CNN target the viewers according to region and give different information to different populations. Websites such as You. Tube obtain information about the last videos viewed on a computer, and propose . Anonymizers are used for avoiding this kind of targeting and getting a more objective view of information. The advantage is that no extra software is needed. The operation occurs in this manner: A connection is made by the user to the anonymizer. Commands to the anonymizer are included inside a typical message. The anonymizer then makes a connection to the resource specified by the inbound command and relays the message with the command stripped out. An example of a protocol- specific anonymizer is an anonymous remailer for e- mail. Also of note are web proxies, and bouncers for FTP and IRC. Protocol independent anonymizers. The technology to do so varies. Protocols used by anonymizer services may include SOCKS, PPTP, or Open. VPN. In this case either the desired application must support the tunneling protocol, or a piece of software must be installed to force all connections through the tunnel. Web browsers, FTP and IRC clients often support SOCKS for example, unlike telnet. Use of multiple relays. Chaining anonymous proxies can make traffic analysis far more complex and costly by requiring the eavesdropper to be able to monitor different parts of the Internet. Tor is not merely a proxy chain, but an onion router, which means that routing information (as well as message content) is encrypted in such a way as to prevent linking the origin and destination. Like all anonymity networks, Tor cannot end- to- end encrypt messages destined for the public Internet. Tor's hidden service protocol does, however, provide end- to- end encryption, along with the ability to anonymize servers to make them more censorship- resistant. Another anonymity network is the Invisible Internet Project (I2. P). Unlike Tor, I2. P is a fully internal network. The philosophy behind I2. P is that each node routes traffic for others and blends its own traffic in, whereas one's own traffic will be relayed by other peers through so- called tunnels made up of various other peers. As you never know if a given mix logs all connections or not, the only way to be really sure there is no logging is to run your own anonymizing mix node and blend your traffic with those of other users, who in turn need not trust you, as they blend their traffic with yours and other users' traffic in their own mix nodes. The network is highly dynamic and totally decentralized. It also takes care of other nodes learning about your node existing, for without peers using your node, there would be no traffic to blend yours with. As all traffic always stay within the I2. P network, a routing user's I2. P can remain end- to- end encrypted and will never show on public websites' logs. Enjoy encrypted Internet browsing and surf web privately.
