In this video, you will learn about the most common ways websites collect and store informationabout people. Then, you will brainstorm additional items for your list.
When you browse the internet, websites install cookies that track what you are looking at.
A cookie is a message that is given to a web browser by a web server.
It identifies a user and allows a business to prepare a customized web page or storeinformation for you.
Cookies save you time loading web pages that you visit frequently. But they also leaveevidence of the sites you visited and how often, which could help people form a profileor make assumptions about you. Geolocation can also add to your digitalfootprint. If an app or website uses geolocation, it records the exact location of your computeror mobile device.
Geolocation allows you to: get directions,find and meet up with people who are close by,track how far you’ve walked, or play games that involve locations.
But photos tagged with your location could also show someone where you live or tell aburglar that you aren’t home. You also add to your digital footprint with metadata.
Metadata is text that is written and added to web pages, images, and files so computersystems and search engines can easily find and share it.
For example, when you take a photograph and post it online, the image may contain metadataabout where the photo was taken, who took it, and when it was taken.
Search engines read the metadata of web pages and images and deliver results related toyour search. Metadata can make search engines work better and faster. But it also adds toyour digital footprint.
Other people can also add to your digital footprint, such as when a friend or familymember tags you in a post or comment. There are many ways that your digital footprintcan grow even when you are unaware that you are leaving information behind.
Now, think about less obvious ways that you could leave digital footprints. Add at leastone item to the spreadsheet.
Finally, resize the column so you can read all the text.
Now, it’s your turn:Brainstorm ways you leave digital footprints behind without knowing it,Add at least one item to the spreadsheet. And resize the column to fit all of your items.
