Also try installing a firewall, or DHCP or you can learn from me! There are situations in which you may want to visit a site without leaving a trace of the visit. For instance you want to check what's going on at your competitor's site. Your visit will generate a record in the log file. Frequent visits will generate many records. Do you want to know what kind of records? See in YOUR REQUEST, YOUR WHOIS RECORD and GEOGRAPHIC LOCATION, Privacy Analysis of your Internet Connection, Another Privacy Investigation Report, BrowserSpy Info, ShowMyIP - will tell you some scary info about what can be told about your computer via the internet. Note that these tests are not very sophisticated. A dedicated "snooper" can often learn much more. Once I came across a server that tried to connect to my computer's disk while I was browsing ... that was an exciting experince. You should also remember about things like cookies, hostile applets and java scripts, browser security holes and so on. So why don't we send someone instead of ourselves? Good idea. Remember that simple owner of Web server may collect information about requests you had performed in search engines, keywords you had typed, your browser and language, date, time, your operating system, physical and geographical position, pages from which you had clicked links and so on. See below some records generated by our server users (real IPs are slightly changed).. Note that large internet companies such as doubleclick, google, government institutions have tremendous possibilities to collect much more information about you and your behaviour.. 24.10.31.1 - - [17/Oct/2006:07:03:22 +0000]"GET /proxy/howto.htmHTTP/1.1" 200 33104 "http://www.google.com/search?complete=1&hl=en&q=change+ip+address+proxy&btnG=Google+Search" "Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7" 217.154.66.1 - - [17/Oct/2006:07:03:25 +0000]"GET /proxy/ HTTP/1.1" 200 37361 "http://www.google.co.uk/search?q=http+proxy+for+ftp&start=0&ie=utf-8&oe=utf-8" "Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-GB; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6" Step #1-Determine your IP Address: Every computer connected to the Internet has a unique identifier called an IP Address. On many networks, the IP Address of a computer is always the same. On other networks, a random IP Address is assigned each time a computer connects to the network. This is what we are referring to when we ask if you have a static or a dynamic IP Address. If a system uses dynamic addressing, the IP can change quite often. Look into REMOTE_ADDR row in THIS LINK to determing your current IP Address. Step #2-Get Anonymous: Method #1: Anonymizer One can surf anonymously and easy with the help of a nice services called CGI/Web proxies. Simply type a URL you want to visit -- the Page does the job for you, selecting random CGI/Web proxy from a hundreds of available services, securing you from many potential dangers. When you follow a link on a page viewed via CGI proxy you get there via the this proxy again, so you don't have to type a new URL. CGI/Web proxy has two more nice features. Firstly, there are WWW sites that are inaccessible from one place, but easily accessible from another. Once I was trying to load a page located in Australia for 20 minutes, all in vain. Using CGI/Web proxies immediately solved the problem. Secondly, there are certain sites that give you information depending on where you are "calling" from. Let's take an example. I was at Encyclopedia Britannica site, trying to check the price for their products. Clicking on Order Information button gave me the list of Britannica's dealers all over the world, no price info. Going to the same place via the Anonymizer led me to a different page, where I found the price list. As it turned out the local dealer's price for Encyclopedia Britannica CD was several times higher than the one at which it's sold in USA. Good savings! Some CGI/Web proxies are able to encrypt URLs (uniform resource locator) in a way that these can be used as reference for a server. If a request with an encrypted URL occurs, they are able to decrypt the URL and forward it to the server, without enabling the user to get knowledge about the server address. All references in the servers response are again encrypted before the response is forwarded to the client. Some CGI/Web proxies are able to use secure HTTPS protocol for exchanging data between proxy and your computer, even if original server is not secure. This option excluding possiblility to sniff a data flow between your computer and this proxy is very useful in some cases, for example, when you are forced to work in possibly scanned/sniffed insecure public network. http://tools.rosinstrument.com/proxy/howto.htm 04/12/2007 07.47.52 Hiding Your IP Address, Anonymous Internet Surfing HOWTO Pagina 2 Method #2: Proxy Servers What is proxy? Proxy - a server setup designed to offer either firewall security or faster access to cached content normally accessible only through slower connections. Proxy server - is the software installed on some network server. The main purpose of this software is to relay traffic between two network hosts (client and server), sometimes this software does some data caching (usually this is performed by HTTP proxies). If your browser is configured to work through the proxy server then all your network traffic will go through that proxy server. The main purposes of proxy servers: Transfer speed improvement (in case of caching proxies). You may use your ISP's proxy to access the internet - usually you have better connection to your ISP's proxy than to other hosts, if this proxy has the resource you requested from the internet you will get a copy of it from proxy (from its cache). Security and privacy (for HTTP). Anonymous proxies hide information about your computer in the request headers, so you can safely surf the net and your information will never be used in any way. LAN interconnection (or LAN to WAN connection). Sometimes you experience some problems while accessing the server located in the other network (for example in the internet). There are 3 types of HTTP proxies: Fully anonymous (elite or high anonymous) proxies. Such proxies do not change request fields and look like real browser. You real IP is also hidden of course. People that administrating internet servers will think that you are not using any proxies. Anonymous proxies also do not show your real IP but change the request fields, so it is very easy to detect that proxy while log analyzing. Nothing really matters, but some server administrators restrict the proxy requests. Transparent proxies (not anonymous, simply HTTP) change the request fields, also they transfer real IP. Such proxies are not applicable for security and privacy while surfing on net. You can use them only for network speed improvement. When Web Proxy Servers are Useful? Permitting and restricting client access to the Internet based on the client IP Address. Caching documents for internal documents. - Selectively controlling access to the Internet and subnets based on the submitted URL. Providing Internet access for companies using private networks. Converting data to HTML format so it is readable by a browser. One can also anonymize one's web surfing by using a proxy server. Proxy servers are similar to the Anonymizer, i.e. web pages are retrieved by the proxy server rather than by the person actually browsing the Web (you). But there are several important distinctions: proxy servers don't help with cookies, hostile applets or code. In most of the cases they do just one thing: they conceal your real geograhic location. Most of proxy servers restrict access based on the IP Address from which a user connects to them. In other words if you have an account with Bluh-Bluh-Com, you can't use La-Di-Da-Net's proxy server, access will be denied. Fortunately you can always find a "kind-hearted" proxy server on the Net the owners of which openly state that the service is publicly available, or a proxy server that doesn't restrict access that due to whatever reason, but the fact is not known to everyone. How do you find a "kind-hearted" proxy server? Good news for lazy people: there are many lists of available proxy servers with periodic updates: http://rosinstrument.com/proxy/ For those who are not so lazy: find your own proxy server, it's real easy. Go to your favorite search engine (Google.com for example) and type something like open public +proxy server list +port 8080, and you'll get the list of Web pages where ISPs give complete instructions to their users of how they should configure their browsers.

    Anonymizing 1 Your Activities In our daily lives we like to have a certain level of privacy. We have curtains on our win- dows, doors for our offices, and even special screen protectors for computers to keep out prying eyes. This idea of wanting privacy also extends to the use of the Internet. We do not want people knowing what we typed in Google, what we said in our Instant Message conversations, or what websites we visited. Unfortunately, your private information is largely available if someone is watching. When doing any number of things on the Internet, there are plenty of reasons you might want to go incognito. However, that does not mean you’re doing anything wrong or illegal. he justification for anonymity when researching malware and bad guys is pretty Tstraightforward. You do not want information to show up in logs and other records that might tie back to you or your organization. For example, let’s say you work at a finan- cial firm and you recently detected that a banking trojan infected several of your systems. You collected malicious domain names, IP addresses, and other data related to the malware. The next steps you take in your research may lead you to websites owned by the criminals. As a result, if you are not taking precautions to stay anonymous, your IP address will show up in various logs and be visible to miscreants. If the criminals can identify you or the organization from which you conduct your research, they may COPYRIGHTEDchange tactics or go into hiding, MATERIAL thus spoiling your investigation.

  • Privacy Enhancing Technologies for the Internet III: Ten Years Later
    Privacy Enhancing Technologies for the Internet III: Ten Years Later Ian Goldberg David R. Cheriton School of Computer Science University of Waterloo Waterloo, ON [email protected] 1 Introduction In 1997 with Wagner and Brewer, and again in 2002, we looked at the then-current state of privacy-enhancing technologies (PETs) for the Internet. [27, 26] Now, in 2007, we take a third look. Technologies to help users maintain their privacy online are as important today as ever before—if not more so. Identity theft is the fastest-growing crime in the US today [47] and it is all too easy for would-be identity thieves to harvest personal information from the online trails Internet users leave every day. Losses of large databases of personal information are an almost daily occurrence [2]; for example, retailers’ servers are penetrated [44], databases are traded between government and private companies [36] and laptops containing social security numbers are stolen [35]. In 1997, we discussed the dossier effect: all available information about a person gets cross-referenced, and the resulting dossier ends up being used for many purposes, lawful and not. This practice has expanded over the years; the companies that compile and sell these dossiers are known as data brokers. Choicepoint is a prime example—in 2005, this data broker sold dossiers on over 150,000 Americans to a group of criminals. [10] The PETs we discuss here give people a way to control how much of their personal information is revealed when they use the Internet. By controlling the spread of this information, they can limit the size of the data brokers’ dossiers about them.
