  1. 1. What is a Cookie?  A cookie is a small text file that is stored on a user’s computer. Each cookie on the user’s computer is connected to a particular domain.  Each cookie can be used to store up to 4kB of data.  A maximum of 20 cookies can be stored on a user’s PC per domain. 
  2. 2.  "a cookie is a unique identifier that a web server places on your computer-- a serial number for you personally that can be used to retrieve your records from their databases”  It's usually a string of random-looking letters long enough to be unique."  Once a cookie is attached or 'set' in your computer, it tracks your movement around the website that sets it and provides this information back to the site's owners.
  3. 3.  The amazing thing about the more intrusive cookies is that nobody would tolerate this sort of behaviour in real life. Imagine, for example, being stopped at the entrance to your local grocery store or gas station and asked to show identification in order to get in. While you're there, imagine being observed by a security guard who takes notes on what you're doing or being recorded by a hidden camera as you walk around. Information gathering cookies are not nearly so obvious, but this is essentially what they do once they get inside your computer.
  4. 4.  The main benefit of cookies is that they help you to navigate websites, particularly those where you purchase goods or services and have to fill out forms with your name, address, and payment information. Cookies remember this personal information so that you don't have to fill out the same form over and over again every time you make a new purchase. Unfortunately, other cookies help the websites that set them far more than they help you.
  5. 5.  They provide personal information that you may not want other people to know. Depending on the nature of a cookie, it can identify the type of computer you're working on, the software you're using, and in some cases, may even be able to get your email address.  Depending on a site's privacy policy (which you should always read), this data may or may not be made available for sale to outside advertisers, marketing firms, junk e-mailers, and more. Many cookies remain in your computer for years or even decades.
  6. 6.  In the worst cases, cookies are set by sites you've never heard of while you're navigating your favorite sites.  These often DoubleClick, come HitBox, from or marketing firms like AdForce that sell advertising, analyze website effectiveness, help increase clients' online revenues, and place or monitor banner ads.  This kind of cookie is capable of tracking your movement from one website to another, accumulating personal data, and sometimes making it available for sale to third parties.
  7. 7.  Fortunately, you can fight back against these invasions of privacy. Websites like contain virtually everything you need to know about who's watching you, what they're doing, how you can find out who they are, and how to control the cookie- setters in order to keep your personal information personal. They post a page about how to delete cookies here, and one about how to control cookies here.  For example, I have my computer set to notify me whenever any website tries to set a cookie in my machine. I have the option of either accepting or declining it. I make this decision in much the same way as I do in real life. If I'm asking for help, making a purchase, or requesting information or services, I usually accept the cookie. If I'd rather look around first, make my decisions later, or find that the site has nothing to offer, I usually decline the cookie. This turns the tables on the cookie-setters. You find out who they are before they find out who you are. You watch them as they follow you around and tell them to leave you alone whenever they get too nosy.
  8. 8.  Two other situations where you should think twice before giving out personal information: * Junk emails that ask you to reply in order not to receive any future mailings. NEVER reply to junk emails; NEVER reply to "unsubscribe" options. Replying is the only way the senders get your email address. They also learn that you read their garbage and reply to it than delete it without ever looking. * Companies that ask you to either call or email in order to get additional information not provided on their websites. You can bet you'll be placed on mailing lists with marketing firms if you do, so think twice about how badly you need what they won't give you unless you give away personal information first.

  12. 12. What exactly is a Web Bug? A Web Bug is a graphics on a Web page or in an Email message that is designed to monitor who is reading the Web page or Email message. Web Bugs are often invisible because they are typically only 1-by-1 pixel in size. They are represented as HTML IMG tags.
  13. 13. Why are Web Bugs invisible on a page? To hide the fact that monitoring is taking place. Are Web Bugs always invisible on a page? Not necessarily. Any graphics on a Web page that is used for monitoring purposes can be considered a Web Bug. Are all invisible GIF images, Web Bugs? No. Invisible GIF files are also used for alignment purposes on Web pages. A Web Bug will typically be loaded from a different Web server than the rest of the page, so they are easy to distinguish from alignment GIF files. What other names are Web Bugs known by? The Internet advertising community prefers the more sanitized term "clear GIF". Web Bugs are also known as "1-by-1 GIFs" and "invisible GIFs".
  14. 14. What information is sent to a server when a Web Bug is viewed? The IP address of the computer that fetched the Web Bug The URL of the page that the Web Bug is located on The URL of the Web Bug image The time the Web Bug was viewed The type of browser that fetched the Web Bug image A previously set cookie value
  15. 15. What are some of the uses of a Web Bug on a Web page? Ad networks can use Web Bugs to add information to a personal profile of what sites a person is visiting. The personal profile is identified by the browser cookie of an ad network. At some later time, this personal profile which is stored in a data base server belonging to the ad network, determines what banner ad one is shown. Another use of Web Bugs is to provide an independent accounting of how many people have visited a Web site. Web Bugs are also used to gather statistics about Web browser usage at different places on the Internet.
