      <![CDATA[<p>I have a question for you. I did a google search for a guy that I like and his website on the internet came up. I then clicked on it to visit and went to a couple of pages on his website. Is there any way that a) he could know the IP address of my computer and b) guess that I visited. If so, is there any way for me to prevent this? By deleting cookies? I don't want him to guess that I googled him!!<br />
<div class="leocomment">Yes. Visiting my site (and leaving a comment) gives me access to your IP address as well. Website owners can see the IP address of site visitors. Tracking it back to you personally is typically not possible and would require the cooperation of your internet provider, which is highly unlikely because of privacy issues.<br />

      <![CDATA[<p>Hi..one more important thing here is that ..the user is  also tracked based on the mac id of your computer.<br />
<div class="leocomment">No. At least not normally. The machine's MAC address does not leave your local network and therefor is not available to web or other servers. (Spyware, of course, can collect whatever ans send it to whomever.)<br />

      <![CDATA[<p>Not being tracked huh? Well how about this? I go to a website and then a pop up window of a sexy girl comes up and says that she is available. She is in the same town as me or there are some that are 25 miles from me. Ok, I clear out my Internet cookies via CCleaner and restart my computer. All my history is cleared as well. I go back to the same website and again sexy girls in my particular area are showing up. My area not anything over 25 or 50 miles but only my area. How can this be?<br />

      <![CDATA[<p>Leo, sorry to contradict you (in terms), but although everything you said was true, there are scores of studies showing that with modern data mining techniques, one *can* trace individual information using aggregate data. Data mining is a technology that is so advanced now that it escapes comprehension to even most seasoned IT professionals.</p>

<p>Now, it is true that most corporations aren't interested in particular individuals. But a particularly aggressive mass-mailer might, totalitarian governments (or branches thereof) might - remember the Internet is worldwide, it's not only used in the U.S., and even there your government's record of late is not exactly flawless in that respect... And identity theft gangs might be VERY, VERY interested in that. Remember they are huge now, extremely rich and well-organized, and difficult to trace and frame because they are internationally based and spread through many countries and continents. The world has no borders, and if Big Brother isn't (yet) watching you, someone else might be...</p>]]>

      <![CDATA[<p>What about the MAC on the NIC card/device?  All MAC addresses are unique in this world.  Couldn't that be used to "know you" even if you had cookies turned off completey?<br />
<div class="leocomment">Not normally, no. MAC's actually aren't always unique (even though they're supposed to be), and they don't travel past the first router your computer is connected to. (I supposed Javascript or other tools could read it and send it along some other way.)<br />

Great article!  I own a medium size ecommerce company (www.tylertool.com) and your dead on.  At best I can see which people used google, yahoo or MSN versus came directly to my site by typing the url.  Without the cookie that tells me it comes from google I would have no idea how much money i should invest in paid advertising.  Without this i don't know my return on ad dollars spent.  <br />
Amazon and the bigger companies may have elaborate data mining resources but the smaller companies really don't!</p>]]>
