A “digital footprint” refers to the trail of data that individuals leave behind while interacting with the internet. This includes information from social media posts, website visits, and online transactions. There are two types, active and passive footprints. Active footprints are created when a user intentionally shares information, while passive footprints are collected without the user’s direct input. Understanding one’s digital footprint is crucial for privacy and security management, as it reveals insights about behavior and personal information that could be exploited.
