Anonymous proxy – Wikipedia
This article is about computer software. For the company, 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 of the user by hiding the client computer’s identifying information. 
There are many reasons for using anonymizers, such as minimizing risk, prevention of identity theft, or protecting search histories from public disclosure.
Some countries apply heavy censorship on the internet.  Anonymizers can help to allow free access to all of the internet content, but they cannot help against persecution for accessing the anonymizer website itself. Furthermore, as information itself about anonymizer websites are banned in those countries, users are wary that they may be falling into a government-set trap. 
Anonymizers are also used by people who wish to receive objective information with the growing target marketing on the internet and targeted information. For example, large news outlets such as CNN target the viewers according to region and give different information to different populations. Websites such as YouTube obtain information about the last videos viewed on a computer, and they propose “recommended” videos accordingly, and most of the online targeted marketing is done by showing advertisements according to that region. Anonymizers are used for avoiding that kind of targeting and getting a more objective view of information. 
For building a reliable anonymous system, anonymous proxy signatures are helpful.  It can be used in anonymous voting or other authentication processes that value anonymity. 
Types of anonymizers
Sometimes anonymizers are implemented to work only with one particular protocol. 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. Potentially anonymity integrated with RFID tags could pose as an option. 
Protocol independence can be achieved by creating a tunnel to an anonymizer. There are various technologies to do so. Protocols used by anonymizer services may include SOCKS, PPTP, or OpenVPN.
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
Proxies can be daisy chained. 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.  An anonymizing remailer can use this concept by relaying a message to another remailer, and eventually to its destination.
Even stronger anonymity can be gained by using Tor. 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; it must be arranged between the sender and recipient. Tor’s onion service protocol does, however, provide end-to-end encryption, along with the ability to anonymize servers, making them more censorship-resistant.
Another anonymity network is the Invisible Internet Project (I2P). Unlike Tor, I2P is a fully internal network. The philosophy behind I2P 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. These other users do not need to trust you, as they blend their traffic with yours and other users’ traffic in their own mix nodes. The network is highly dynamic and fully 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 stays within the I2P network, a routing user’s I2P can remain end-to-end encrypted and will never show on public websites’ logs. 
Examples of anonymizer websites include Anonymouse,, Anonymize, Anonymizer, IDZap, Ultimate Anonymity, The Cloak and GhostSurf Platinium.

Do proxies really provide anonymity? – Server Fault
Do web proxies really provide anonymity?
I mean, without someone asking for logs in a web proxy server for who/when connected, is it impossible to know who was behind that IP address?
I’m asking this because I heard somewhere that some technologies (like “flash”) bypass personal IP information for requests or something like that.
(I’m a noob in server configuration and concepts like DNS and proxies. Thanks! )

No, just setting a proxy within your browser not make you anonymous.
Your browser and flash is likely to have cookies that will identify you.
If you wanted to be truly anonymous you would probably need to fire up a new browser from a livecd or in a VM, set the proxy, and then browse. To maintain your anonymity you must not login to any site that has your name.
You will probably also need to make sure the browser/OS you are using does not make DNS requests to a local DNS server. If you do not configure the proxy correctly your machine make make DNS requests for the sites you are visiting to the local network.
If the proxy you are using is not using SSL for transport your ISP or someone on the local network will still be able to see what you are doing. Even if they are using SSL your ISP will know you are contacting that proxy.
If the an evil person cannot get the logs from the proxy machine to get the logs. if they are able to monitor the incoming and outgoing traffic they still may able to identify you just by looking at the flows of data.
Something like TOR does the best job, but even with it you must be very careful that you set it up properly and that during your session you never reveal any information that would unmask you.
It depends on what you’re trying to obscure and how it’s configured. Proxies aren’t meant to hide people; they’re meant to cache data, and later they started scanning content to filter it or protect people on the inside from malware. Anonymous proxies act anonymously by promising to not give out or retain logs (you have to trust them on that) and anyone trying to trace where the request is coming from is stopped at that hop if the proxy strips data out of the request that is personally identifiable.
Basically, the proxy has to be configured specifically to strip out identifiable data.
If the request or post information has your ID or personal information or something like that embedded in it, then that kind of defeats the purpose too.
If the request has to get back to your computer somehow, there is definitely a trail that leads back to you. Just depends on how obscure it is to trace. Commercial anonymizers just promise to stonewall by purging logs and stripping data from the request (if you trust them), and networks like Tor obscure your request by bouncing it all over the place (more info on their website) to obscure it and make tracking extremely difficult.
If you run a proxy at home, it doesn’t take a forensic expert to know that there’s a very limited number of people that could be making web requests from that home network.
But if you were truly 100% would the data get back to you?

I run a squid server at home, with a very basic/default setup, and I’ve seen websites identify me by my internal address. I’m not sure if the website is getting from my browser or the proxy, but it definitely can be found with my particular setup.
Knowing your internal IP addy really isn’t a big deal. NAT (or proxies that accomplish the same thing) violates the principles of end-to-end routing in the first place, since there are now computer connected to the Internet (through a NAT router) which do not have a “routable” address. I wouldn’t call your IP personal information, not anymore than the street address on the front of your house.
To your larger question about proxies providing anonimity. Cookies can uniquely identify you with or without proxies. Websites can also do a browser fingerprint on you, and that basically uniquely identifies you without a cookie.

>Anonymous proxies do many things, such as change an ip address, encrypt information, and most of all ensure a person’s safety. A proxy will supply you with a fake ip address in place of your old one. This will keep anyone from knowing your true identity on the internet. The key behind how anonymous a proxy really is, is owning a proxy under a reliable company. Everything you do on the internet will go through the company’s proxy first, so the company could just be out to steal your personal information.

The best answer I can give is “up to a point”. Even if the proxy is configured to strip out anything that might identify you, the operators are scrupulous and the system is impenetrable against hacking (as if! ), depending on local laws it may still be required to maintain logs that can identify your machine. It may sound a bit altruistic but I think an operator that disrespects the law should probably not be trusted to respect your privacy.

Frequently Asked Questions about untraceable proxy server
Can a proxy server really hide your identity?
No, just setting a proxy within your browser not make you anonymous. Your browser and flash is likely to have cookies that will identify you. If you wanted to be truly anonymous you would probably need to fire up a new browser from a livecd or in a VM, set the proxy, and then browse.
Are proxy servers detectable?
It’d be impossible to detect all proxy servers, but some can be detected. Proxy providers continually change their IP addresses to try to avoid detection. There are multiple lists of known proxy IP addresses available online, and ipdata combines many of them, along with proprietary lists to detect the larger proxies.Sep 14, 2020
What is a transparent proxy server?
A transparent proxy, also known as an inline proxy, intercepting proxy or forced proxy, is a server that intercepts the connection between an end-user or device and the internet. It is called “transparent” because it does so without modifying requests and responses.
