A digital footprint refers to the trail of data that individuals leave behind when they interact with digital devices or online platforms. This footprint includes information gathered from social media activities, website visits, online purchases, and communications. Digital footprints can be categorized into two types: active, where users intentionally share information, and passive, where data is collected without direct input. Understanding digital footprints is essential for managing online privacy and reputation since they can influence how individuals are perceived by others and organizations.
