The term digital footprint refers to the traceable data generated by individuals when they use the internet. This includes information left behind while browsing websites, posting on social media, or engaging in online transactions. A digital footprint can be categorized as either active, where users deliberately share content, or passive, where data is collected without direct input (e.g., cookies, analytics). Understanding one's digital footprint is essential for managing online privacy and reputation, as it can have lasting implications on personal and professional lives.
