Have you ever considered how much information you provide to web sites and advertisers when you surf the internet? For instance, if you do not log out of your Facebook, Google or Yahoo accounts, as well as other social network sites, and then surf the web, you are being tracked.
You can use a proxy server to mask some of your internet activity but you must remember to log out of your accounts before browsing the internet. And even if you log out of those accounts, your internet service provider (ISP) logs your activity. Even if you use a proxy, the web site you visited is known to your ISP; the site you are visiting may not know your point of origin, that is, your IP address.
There is another way to surf the internet masking your activity so that your ISP and the site visited does not know your IP address. This can be accomplished using a TOR browser and the TOR service. You need only download the TOR service software that includes the Firefox browser and you are set to surf the internet anonymously. Using the TOR service will be a bit slower due to the many connections it makes, but if security is your main concern, the trade-off is well worth the slight delay.
From the TOR Project site:
“Why Anonymity Matters
Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.”
