Joint Project: 3D4F

Contactless personal identification using a forgery-proof 3D 4-finger scanner

Biometric features of face, hand, iris, teeth are used as a measure to determine the unique identity of individuals in dealings with authorities. Particularly in the context of merging markets, the resulting international travel and also the refugee movement, which we currently experience, place increasing demands on the established contact-based fingerprint systems: Enrollment should be fast and robust, especially when users from a wide range of cultural backgrounds have to interact successfully with the device without prior knowledge or assistance. At the same time, proper hygiene must be maintained and the transmission of microorganisms such as bacteria and viruses must be prevented. These requirements presuppose a high degree of automation, in which it must be determined, possibly by a machine, whether an attempt at deception has been made.

The aim of the project is to develop a demonstrator for a 4-finger scanner that meets all these requirements on the basis of a new technology. The detection is contactless and irritation-free for the user by means of 3D sensor technology - for all four fingers simultaneously. An important goal is user acceptance in the operation and handling of the system. At best, users should feel that they are fairly treated and that they are not subject to a system error.
