The concept of the digital twin comes originally from the Industry 4.0 domain with the idea of having a digital representation of real-life objects or processes. The representation of the digital twin consists of the physical object, the virtual product, and the connections between those. Data and its flow form the connection. Only recently has this concept been applied to people as well. While this concept is very promising for design or optimization scenarios, the fact that data is in the center of it, a missing overall data governance and security might be the next challenge. Thus, potentially leading to a misbehavior of the digital twin.
