When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.
How do people get this basic information about you?
When you visit another web site, information about you can be
retrieved. Basically, information is
intercepted and used by others to track your Internet activities.
How do you stop this from happening?
First of all, it is possible to serf the web anonymously and thereby
stop leaving a trail for others to find. Note that this is not fool-proof, but
it makes it much harder for people to know who you are. There are products
called anonymous proxy servers that help protect you. The anonymous proxy server replaces your
Internet address for its own. This has
the effect of hiding your IP address and making it much harder for people to
track you.
How do I get an anonymous proxy server?
There are many vendors who sell anonymous proxy servers. There are also
free proxy servers available to you. Two such products are ShadowSurf and
Guardster. Guardster
(http://www.guardster.com/) offers various services for anonymous and secure
access to the web, some paid as well as a free service. ShadowSurf
(http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at
their site for free. Go to it and you will find a box to enter a URL that you
want no one to track. There are many others, but here are two that are
frequently used.
Another interesting product, given the recent news about the Google
search engine filtering its findings for the Chinese government, is Anonymizer
(http://www.anonymizer.com). This company, among others, recently (Feb 1st,
2006) pressed that it "is developing a new anti-censorship solution that will
enable Chinese citizens to safely access the entire Internet filter-free"
(http://www.anonymizer.com/consumer/media/press_releases/02012006.html).
Does an anonymous proxy server make you 100% safe?
No. Still, you are much better
off if you use such technology.
What other things should I be concerned
about when trying to keep my private information private?
Three other items come to mind when
trying to keep your information private. First, you can use an encrypted
connection to hide your surfing. This article does not go into detail on this,
but search the web and you will find a lot of information on this. Secondly, delete cookies after each
session. Third, you can configure your
browser to remove JavaScript, Java, and active content. This actually leads to
limitations, so you need to think about the cost/benefit of this course of
action.
Anything else?
Wishing you happy and safe surfing!
