In the realm of digital identity, there exist two distinct types of infrastructures: Visible and Hidden Digital Identity Infrastructures. Identiverse primarily concentrates on what's visible, yet it is crucial to recognize and comprehend the all the aspects that are hidden from individuals, notably the use of universally unique identifiers that silently track our activities on the Internet. This hidden infrastructure, often invisible and inescapable for users, stands at the core of ongoing privacy debates. The presentation delves into the history and intricacies of hidden digital identity infrastructures, highlighting the risks associated with concealed digital identities, and emphasizes the significance of identity minimization as a key principle for software safety. Furthermore, it will examine the interplay between visible and hidden digital identities, shedding light on their interconnected roles and impacts in the digital world.
