A digital footprint is a unique data trace of a user’s activities, actions, communications or transactions in digital media. This data trace can be left on the internet, computers, mobile devices or other mediums. A digital footprint can be used to track the user's activities and devices. A user can leave digital footprint either actively or passively, but once shared, a digital footprint is almost permanent in nature.
Technology users are frequently involved in digital activities, either actively or passively. However, whatever they do, there is always a data trace left behind which shows users' activities. If required, those activities can be tracked back.
This digital footprint can be shared actively or passively. In active data trace, users share their activities intentionally, like social media activities, online chatting, phone calls or blog posts. Here the data is shared publicly or semi-publicly.
In passive data trace, the footprint is created unintentionally. Here the users do not share the data, but the trace is left behind, and it can be used to track back the users' activities. It includes activities like searching the internet, browsing websites, online purchases, online forms or online surveys. This data is sometimes used to understand user sentiments, marketing trends or analytics.
