What You Need to Know About Cookies and Web Beacons
By Gretchen S. Herault, CIPP
A cookie is a text file that’s either stored in your computer’s memory temporarily and automatically deleted when you close your browser (a “session” cookie) or placed on your hard drive (a “persistent” cookie) by a Web page server. A persistent cookie is not deleted when the browser is closed.
Since cookies are text files, they cannot read information stored on your hard drive and are not used to run programs or deliver viruses to your computer. Cookies are uniquely assigned to you and your computer and can be read only by a Web server in the domain that issued the cookie to you.
So what do cookies have to do with privacy? Some Web sites, including Monster, use third-party cookies to track traffic coming to their site from advertising they run on other sites. While the information these cookies collect is anonymous, you may end up with a cookie on your hard drive from a site you’ve never visited as a result.
If you are still uncomfortable with cookies, you can accept or decline cookies at any time by modifying your browser settings. Most browsers are set to accept cookies automatically. You can set your browser to decline all cookies automatically or to prompt you for a response each time a cookie is offered. Note that declining cookies may hinder a site’s performance and may not allow you to access all of a site’s features and services.
Web beacons, which are also known as clear GIFs, Web bugs or pixel tags, are often used in combination with cookies. They are images (often transparent) that are part of Web pages. At Monster, Web beacons allow us to count users who have visited certain pages and to generate statistics about how our site is used. They are not used to access personally identifiable information.
Unlike cookies, you cannot decline Web beacons. However, setting your browser to decline cookies or to prompt you for a response will keep Web beacons from tracking your activity.
