Cookies are tiny files that are downloaded and stored on the hard drives of Internet users' computers just like the pictures and text from a Web site. When a user returns to a site that has previously placed a cookie, the browser sends information in the cookie to that site. The site then "recognizes" the user and can deliver information to that user in appropriate ways. Cookies allow Internet users to customize their experiences by, for example, selecting layout, news preferences, language preferences, and so on.

Cookies almost always contain unintelligible letters and numbers, not personal information. However, a Web site can associate the string of characters in a cookie with a particular browser and collect information about a particular user that way. This is complicated by the fact that sometimes multiple people use a single computer to surf the Web, and sometimes a single person uses multiple computers to surf the Web.

Users who are worried about revealing personal information to Web sites using cookies can set their browsers not to accept cookies. All modern browsers provide some sort of cookie management capability that allows users to refuse them all, decide which to accept, or block them by site. There are also several tools on the market that make it easy to read and edit cookies.

To the extent cookies present a privacy problem at all, it is a problem that will vanish as consumers learn how their computers work. Cookies are a privacy issue in the same way that window drapes are a privacy issue. Consumers who want sunshine open the drapes. Consumers who want privacy close the drapes. Consumers who want customization accept cookies. Consumers who want privacy do not accept cookies.
