What is my digital footprint? The moment you use a computer or cell phone, you leave data tracks. They can include your phone number, your computer’s serial number, the country you live in, the language you use, your browser history, your fingerprint, or the location where you access a Wi-Fi network and the internet. Many smartphone apps and social media platforms also record when you use them and for how long. In addition, some of them store your address, your e-mail address, your contact list, your photos and videos with all their metadata, your list of friends and groups, your likes, shares, and messages. They store it to tailor their services to your preferences, but they may also sell this metadata to advertisers, governments, or interest groups. Data and metadata say a lot about you. The technology you use
makes it possible to trace or identify you. This data may also reveal some things you might rather keep private. Your Facebook likes, for instance, can often reveal private beliefs and personality traits, or identify your political viewpoint or sexual orientation. These data traces are easy to tap into. Ultimately, your life becomes more and more transparent to those who store, buy, or even steal your data.
