Digital footprints are the records and traces we leave behind us as we use the internet.
Digital footprints come with both benefits and costs.

Your own digital footprint may contribute to your online reputation. Your digital footprint can mean you don't have to repeatedly log in or submit personal details to web sites. On the other hand, your digital footprints may allow others to follow your actions, such as which web sites you use, what things you search for, and who is in your social circle.

Each time you visit a web site, you reveal some information about yourself to the owner of the web site: your IP address, which may include your geographic location, your web browser type and operating system, and, often, the last web site you visited. These bits of information seem relatively innocuous and even fairly anonymous. If these are footprints, they are fairly light ones.

One solution to this problem is the cookie. WHICH PROBLEM?????
A cookie is one way of tying multiple actions by a single user into one connected stream.
A cookie is an arbitrary string of letters and digits - something without any inherent meaning - that a web site sends to your web browser.

Digital footprints in the form of cookies are used to make the Internet more usable, and can also help make individual transactions more secure.

Web sites generally set a cookie in your browser at the instant when you first visit the site. The web site can store profile and preference information in the cookie.
