Find out how you are traced while surfing on the Web

Using Find File, look for a file called cookies.txt (or MagicCookie if you have a Mac machine). Using a text editor, open the file and take a look. If you've been doing any browsing, the odds are about 80/20 that you'll find a cookie in there from someone called "doubleclick.net".

If you're like me, you never went to a site called "doubleclick". So how did they give you a cookie? After all, the idea of the cookie, according to the specs published by Netscape, is to make a more efficient connection between the server the delivers the cookie and the client machine which receives it. But we have never connected to "doubleclick".

Close MagicCookie, connect to the Internet, and jump to www.doubleclick.net (http://www.doubleclick.net) Read all about how they are going to make money giving us cookies we don't know about, collecting data on all World Wide Web users, and delivering targeted REAL TIME marketing based on our cookies and our profiles. Pay special attention to the information at:advertising/howads.htm You'll see that the folks at "doubleclick" make the point that this entire transaction (between their server and your machine) is transparent to the user. In plain English, that means you'll never know what hit you. So what's happening is, subscribers to the doubleclick service put a "cookie request" on their home page for the DoubleClick Cookie.

When you hit such a site, it requests the cookie and take a look to see who you are, and any other information in your cookie file. It then sends a request to "doubleclick" with your ID, requesting all available marketing information about you. (They're very coy about where this information comes from, but it seems clear that at least some of it comes from your record of hitting "doubleclick" enabled sites.) You then receive specially targetted marketing banners from the site. In other words, if Helmut Newton and I log on to the same site at the exact same time, I'll see ads for wetsuits and basketballs, and Helmut will see ads for cameras. If you log in to a "doubleclick" enabled site, and it sends a request for your "doubleclick" cookie, and you don't have one, why each and every one of those sites will hand you a "doubleclick" cookie. Neat, huh? And you can bet they're going to be rolling in the cookie dough.

The main concern is that all this is done without anyone's knowledge. Some people may find the gathering of any information invasive to their privacy, but to the average level headed personal, the use of this information is harmless in itself as long as you know the limitations of these networks, who is collecting what information and for what purpose. On the other hand, what right should anyone have to collect information about me without my knowledge, and why should they break my right to privacy, you have to find the right balance between these views. One of the main issues is awareness.

So much for making the "client-server negotiation more efficient", whatever your view on tracking, the cookie protocol has certainly been manipulated for this use, against its original intent. Note that recent versions of Netscape have an option to show an alert before accepting a cookie and they also allow you to block cookies completely, see the Version 4 update and the Stopping Cookies page for more detailed information

One more piece of information: You wonder who uses these here computer cookies?....Oh let me tell you the ways: ever here of Google? Yahoo? your internet provider? New York Times? Toonzone is the only organization that claims to remove cookies after you log out....have fun on the net...oh, later I will put on this thread, if anyone reads it...How to remove all computer cookies from your computer.....Stuart

Use Firefox, it leaves no trace of cookies, cache, history and temp files, because it stores them in RAM, therefore no phisical file tempering.

I use Firefox.......you have to delete cookies from the Firefox program..sometimes it misses them...When I run Adware..I still find cookies....Stuart

So... just delete them. Privacy is an utter joke in today's world, though. Forget the information sites are collecting with cookies, you don't even want to know what a skilled professional could dig up on you.

I agree...a skilled dedicated professional, with as much knowledge as is possible..well, everything you ever did,owned, own now can be discovered, and probably hacked into...depends on the firewalls of the institutions you are dealing with...excellent point Auroa...

I think if you use Adware, and Spybot, along with reading this article..you will probably be free of computer cookies...But as Aurora pointed out a few posts back, a real professional hacker, can probably get any personal info on you that he/she desires...It is sad indeed:sweat: But I did say that I would post this, and I am going to keep my word.

How to Block Tracking Cookies (from the Washington Post)

Q: How do I stop these tracking cookies that my anti-spyware software
keeps bugging me about?

A: The exact procedure isn't always obvious, but it requires at most
seven -- and sometimes zero -- taps of the mouse button in your Web
browser.

In Internet Explorer 6 (the version available since summer 2001), go
to the Tools menu, select Internet Options and click the Privacy tab.
Then click the "Advanced . . ." button; in the smaller window that pops
up, check the box next to "Override automatic cookie handling" and
choose "Block" under the "Third-party Cookies" heading. Click the OK button
to confirm that setting.

In Mozilla Firefox, go to the Tools menu, select Options and click the
Privacy icon. Click the Cookies heading to display the
cookie-acceptance policy, then check the box next to "for the originating Web site
only." Click the OK button.

In Safari, you don't have to do anything -- its default setting is to
accept cookies "only from sites you navigate to," excluding those from
third-party sources.

Cookies, in case you've been wondering, are little text files,
measuring no more than a kilobyte or so each, that Web sites put on your
computer as a scratchpad to store data. For example, many Web-based e-mail
sites use cookies to store your user name, so you have to type in your
password only when you log in.

Tracking or third-party cookies come from outside the site you're
visiting -- usually, from advertising agencies that place ads at many
sites. These companies can combine data gathered by their cookies to see
what you read at different sites, but they can learn your identity only if
you (or the sites that buy their services) provide that to them.

There are far bigger privacy risks to worry about, online and off,
than tracking cookies. But just in case, I've had my browsers set to block
third-party cookies for the past few years. I haven't met the slightest
inconvenience as a result.

Even if you delete your cookies I can still get them back trough your recycle in (even if it’s empty). Now, there isn't a person in this internet that could get to my pc without me knowing about it. I run about six different hardware/software firewalls, spy detectors, anti-key loggers, skip signals and switching nodes. The only ways you can truly protect your self without doing what i do on a daily basis, DON"T GO ONLINE. If you do go, delete your cookies daily but not through the recycle bin. There is a program called System Mechanic 5, it has a program called Incinerator. It puts a recycle bit type file on your pc. When you want to delete your files drag them into the incineratror instead of the recycle bin. When you delete your cookies there is an overwrite level 1-10. If you choose 7, it is government compliant standard for cleaning their PCs, so not even the government can get back what you deleted. The only problem, the higher the level, the longer it takes. And remember, what ever you delete from your recycle bin, it can always be get back.

My computer is even more secure: First, I disconnected my computer from the internet. Secondly, I ran a very large magnet over my hard drive. Afterwards, I smashed my computer into a zillion pieces, put the pieces in a very large hole (the location of which I'll take to my grave), and then filled the hole with concrete. I'm quite sure the sensitive documents on my computer are safe from prying eyes. :shrug:


Kidding aside, I have Norton Ghost loaded on my computer. Nifty piece of software. Essentially, a year ago I completely reformatted my computer and performed a clean install of my OS and core programs. I then copied the image of my drive to another partition ala Norton Ghost.

Since then, every six to eight weeks I do the following:

1) Wipe my current configuration and restore the image
2) Perform any software / hardware / Firewall / AV / adaware updates
3) Recopy my new image to another partition

This way, my computer always retains it's "freshly reformatted smell" :p It helps if you change the location of your "My Documents" folder and your browser settings to a partition other than your active partition so you don't lose your muisc, photos, videos, documents, etc. with each wipe.

While I have a firewall, antivirus software, a secure browser (firefox), and adaware software, wiping my drive clean every two months ensures anything that happend to get through is eradicated.

Yea sure, I can get back any info you deleted after your "wipe". Let me guess you went into comand prompt and tiped "Format C:". I can get the info back. What I do is I have a program called Disk Scrubber, I zero Format my HDD and overwrite the data 7 times (DOD protocol). That way not even the government can restore those files. :evil: Gotta know your stuff.

What the hell do you have on there? Nothing bad or ilegal, don't worry. I am a white collar hacker (I help companies identify holes in their systems and firewalls). I have all kinds of data on all kinds of firewalls and encryptions. Hackers want that kind of info.
