A digital footprint refers to the trail of data a user leaves online through various activities. This includes social media posts, online purchases, searches, and interactions with websites. Digital footprints are generated when users engage with digital platforms, creating a record of their online behavior. They can be categorized as active (where users deliberately share information) or passive (where data is collected without direct input, such as through cookies). Understanding one’s digital footprint is crucial for maintaining privacy and managing online reputation, as it can significantly impact personal and professional relationships.
