The concept of Identity, its representation and the definition of its attributes see essential changes in its translation into the digital world. The elements involved in the process of identification and authentication, attributes and identifiers, are created into a virtual world where physicality vanish and elements of trust evolve, challenging the digital citizens. How the digital world influences the construction of our Identity, of our Trust is essential question to be considered.

This report provides an eagle-eye view on the concept and implications of Digital Identities. After an introduction situating the concept of Identity, the report clarifies its contemporary meaning and proposes a definition of reference. In a second time, the authors examine the consequences of the translation of the concept of Identity into the digital, internet-connected world. They analyse then the particularities and consequences of this translation which allow them to situate and define the concept of Digital Identities. Finally, they conclude by the challenges that Digital Identity poses to the digital citizen in the attempt to manage and protect its attributes with the advent of Internet of Things and Blockchain technology.

An account by Henning Eichinger of the artistic process of the Skypelab project, searching the evolution on Portraits and Identity in the Digital world since 2012 prefaces this report and provides a complementary perspective on the subject.
