Many organizations that operate a Web site place a cookie—a small file containing a string of characters that uniquely identifies a customer’s browser—on the computer hard drive of visitors to the organization’s site. For each visit to the Web site, data about user preferences and activity is captured and stored under that cookie on the company’s Web server. Additional information that a customer submits, such as name, address, and credit card information, as well as information gleaned from third parties, is also associated with the cookie and added to the customer’s file on the server.
