When you use the internet, you leave behind a trail of data, a set of digital footprints. These include your social media activities, web browsing behavior, health information, travel patterns, location maps, information about your mobile device use, photos, audio and video. This data is collected, collated, stored and analyzed by various organizations, from the big social media companies to app makers to data brokers. As you might imagine, your digital footprints put your privacy at risk, but they also affect cybersecurity.
