A digital footprint refers to a trail of information that is generated as an activity of an individual on the internet. It contains information created by using social media posts, visits, and purchases on websites, the use of apps, and digital communications. The digital footprints may be active, like the material published on purpose, or passive, like the information gathered using cookies and tracking technologies. This data may affect online reputation, privacy and security. Maintaining an online presence is valuable for ensuring one retains control over their personal data and is not exposed to abuse or undesirable monitoring.
