Since last November, the time has come: biometric features such as two-dimensional facial and, in the future, fingerprint data are integrated in all newly issued European passports. In order to further improve this safety system, scientists are working on the development of a 3-D face recognition system in the "3D Face" project, which can be used, for example, at border controls.

The previous 2-D face recognition has some significant disadvantages. Especially the recognition performance of the 2-D face scanner is still not satisfactory. For example, the incidence of light or the inclination of the head in the 2-D face detection have a strong influence on the recognition quality. In addition, it is very complex to detect deceptions, for example, with printed photographs.

"3D Face" started

To make access and border control even safer in the future, the European Union has launched the "3D Face" project. The Fraunhofer Institute for Computer Graphics Research IGD is head of the sub-project "Research and Technology" and is to develop a prototype for a three-dimensional recognition system. The project not only aims to achieve better scanner recognition, but also to develop a new, forgery-proof sensor technology. In addition, the researchers are working on technologies that better protect stored private data.

By combining accurate profile information and facial color and texture, 3-D recognition systems can better handle changes in position and difficult lighting conditions. The difference between the real person and photography is immediately apparent to the system. Combined with classic two-dimensional facial recognition, the procedure is therefore safer and more robust than two-dimensional facial recognition alone.

International cooperation

Within the sub-project "Research and Technology", the biometrics experts of the Fraunhofer IGD continue to develop detection algorithms and are responsible for the construction of the prototypes. In addition, the Fraunhofer researchers and Philips Research ensure that the biometric data stored in the system is protected against misuse. In addition, the staff around department head Alexander Nouak participate in the final tests on the performance of the developed systems. "As part of the Bioface project series, which we conducted for the German Federal Office for Information Security (BSI), we have already gained extensive experience in the development of three-dimensional detection algorithms and testing of biometric systems, which we can now use in the 3D Face project and continue to expand, "says Nouak. display

Under the leadership of the syndicate and project manager Sagem Défense Sécurité, France, a total of twelve partners from five European countries are working on the project, including the Fraunhofer Institute for Computer Graphics Research IGD and the Center for Computer Graphics, both in Darmstadt, The 3D Face project has a total volume of 12 million euros over a term of 36 months.
