Karola Marky, Martin Schmitz, Verena Zimmermann, Martin Herbers, Kai Kunze, Max Mühlhäuser
2020 Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems  
We present customizable 3D-printed items for authentication: the user interacts with the item in order to activate an authentication pattern on the object's bottom.  ...  The authors would furthermore like to thank Marco Fendrich for 3D-printing the prototypes for the user study.  ...  To tackle these usability and customization issues, we present 3D-Auth items. 3D-Auth items are 3D-printed authentication items that combine the factors ownership and knowledge.  ...

Privacy-Sovereign Interaction : Enabling Privacy-Sovereignty for End-Users in the Digital Era

Karola Marky
A concept for two-factor authentication utilizing individualizable 3D-printed objects is developed, implemented, and evaluated to realize these requirements.  ...  Based on the results, requirements for usable and customizable two-factor authentication are described.  ...  Second, the concept of 3D-Auth is presented. 3D-Auth is a customizable concept for two-factor authentication based on individual 3D-printed items that do not require an additional energy source.  ...
