Digital identity refers to all the data and information that can identify a person on the internet, including traces left intentionally or unintentionally on social networks, websites, and other online platforms. It combines real and virtual identity and is built from an individual’s interactions, publications, and contributions, as well as data collected by third parties. Managing this identity is essential because it influences online reputation and can have repercussions in real life. It also raises ethical and legal issues related to the protection of personal data and surveillance.
