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. ...doi:10.1145/3313831.3376189 dblp:conf/chi/MarkySZHKM20 fatcat:buq5srwetnaj5c4lnsrakf2hdu
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. ...doi:10.26083/tuprints-00017366 fatcat:gzq6ufhy2beu5dcefwskjw5jtq
