Have You Tossed Your "Cookies" Yet?

Cookies are rapidly becoming a topic of alarm for some of us who travel the Web. Several members of our group and a few of my students have recently approached me about this subject and asked whether they should be concerned. One person was in a state of near panic. What are "Cookies"? What do they do and is there cause for anxiety?

Cookies are text files stored on your hard disk. Your Web browser creates and uses them to identify you to a specific Web site to keep track of your activities at that site. If you are using Netscape, you have a file called "COOKIES.TXT" somewhere on your hard drive. Microsoft's Internet Explorer stores cookies in a folder called "Cookies," a sub-folder of your "Windows" folder.

Webmasters are not usually spies or casual snoops. Before you start hollering "Big Brother is watching me," take a moment to think about how the cookie is being used and for what purpose. They are attempting to track your preferences to build a profile. They do not monitor every step you take on the Web. Because of the way that connections are made on the Internet, cookies will not and cannot tell a Web site your name and address, only that you or someone using your computer has visited the site previously along with whatever details it wishes. This information is used to bring up ads you are more likely to respond to or to keep you from having to move through multiple levels of Web pages every time you visit the site. Cookies can identify you to a site and let you log in automatically without a user identification or password.

Much of the anxiety about cookies arises from two almost universal assumptions held by computer users. One is that exploring the Web is an entirely confidential, anonymous experience that leaves no traces of itself. That's a little like expecting your everyday activities in the real world to be completely invisible to others. The other is that your hard drive is your castle and should not be tampered with without your knowledge and explicit permission. OK! I can buy that one.

Let's examine some of the issues:

Cookies Collect Information about You.

Cookies don't collect anything. A cookie is simply a text file. Web servers might collect information if you supply it to them and the server might then deposit that information to the cookie.

Cookies Are Programs That Web Servers Send to Your Hard Drive.

Cookies are not programs. They are text files used to save session information between the times you visit the same Web site.

The Information in Cookies Can Be Used for Marketing Purposes.

This is true, but is limited to the information that you supply to the Web site.

Cookies Pose a Serious Security Risk.

Your risk is entirely determined by whatever information you are willing to supply to the Web site.

Cookies Can Be Used to Steal Passwords, Credit Card Numbers, Etc.

A Web site might accept your credit card number if you give it. Security is about the same as providing your credit card number over the phone. There is always some risk, however slight.

If you feel that cookies are an unwarranted invasion of your privacy simply erase them from your hard drive and that will be the end of it. Then weld the front door of your home shut because it could be used by dishonest people to enter your residence. Regardless of how you feel about them, cookies will be with us for a long time to come. Web sites will continue to ask your browser to store cookies and your browser will oblige. Cookies can be very useful, but there are some legitimate privacy concerns. It's up to you to decide how much these privacy issues really matter and make the appropriate choices. The choices are up to you, but if you don't make them the Web will.

About the worst that will happen is that you'll receive more junk E-mail, but you will also get more Web content tailored to your preferences. One piece of data that Web servers can get from almost any browser without even using a cookie is your E-mail address. Browsers have this information so if you click to send E-mail to a Webmaster, no problem. If one knows how to combine E-mail addresses, cookies and data from multiple sources, you end up with a real data base.

Check out http://www.cdt.org to see what your browser can tell a Web site about you. To gain a sense of the kinds of information Web sites may already know about you and your E-mail address visit http://www. whowhere.com and see what information this site has collected on you.

Cookies have been called the greatest marketing tool in history. Others say cookies should be outlawed because unscrupulous people can use them for fraud. Any tool can be used or misused. The majority of fraud in our society is done either through the mail or over the telephone. Does that mean we eliminate the Post Office and shut down AT & T? I hardly think so.
