- KonferenzbeitragOn Combining Classifiers for Assessing Portrait Image Compliance with ICAO/ISO Standards(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Storer, Markus; Urschler, Martin; Bischof, Horst; Birchbauer, Josef A.The International Civil Aviation Organization (ICAO) has selected biomet- rics - in particular face - as the technique for travel documents to verify the association between such documents and the person in possession of them. The International Stan- dard Organization (ISO) has defined a standard for the digital face images to be used in Machine Readable Travel Documents. Due to the ISO/IEC 19794-5 international standard, there exists a high demand for automatically checking portrait images to as- sist civil service employees in decision making regarding ICAO/ISO compliance. We present a face normalization and analysis system implementing several requirements of the ISO/IEC 19794-5 specification. We address the criteria eyes-open and mouth- closed and highlight the fusion of complementary classifiers to boost performance of the overall analysis system. Our results show that classifier fusion is capable of im- proving the classification performance considerably as compared to a single classifier decision.
- KonferenzbeitragA Federated Identity Management Architecture for Cross-Border Services in Europe(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Posch, ReinhardIdentification is the basis for trusted relationships in business as well as in administration. In Europe Member States have developed rules and methods how citizen and businesses are identified electronically. Cross-border applications still suffer from the fact that these methods differ from the legal, from the organisational but also from the technical point of view. Federated and interoperable identity management can contribute to a seamless way of offering electronic services. Taking into consideration that such cross-border services need to fit into the existing structure models and structures of interoperability are discussed with a special focus on the needs of government applications.
- KonferenzbeitragA Reference Architecture for Biometric Template Protection based on Pseudo Identities(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Breebaart, Jeroen; Busch, Christoph; Grave, Justine; Kindt, ElsBiometric authentication is often considered to enhance identity verifica- tion. The use of biometrics also introduces new challenges to protect the privacy of the subjects while at the same time increasing the security of a verification system. In this paper, a set of requirements is proposed for biometric processing techniques to safeguard privacy and security. From these requirements, a reference architecture is derived that outlines processes and interfaces of biometric template protection meth- ods in a high-level, technology-neutral way.
- KonferenzbeitragCross-Context Delegation through Identity Federation(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Peeters, Roel; Simoens, Koen; Cock, Danny de; Preneel, BartWe present in this paper a basic scheme for delegation in a federated setting and two more advanced schemes, transferable and corporated delegation. By transfer- able delegation delegatees are able to delegate the received privileged actions further to someone else. Corporate delegation is delegation within a business context. Our schemes are generic and user-centric. We elaborate on the different procedures to is- sue, accept and revoke mandates in these schemes. Different variations are discussed and their impact on the corresponding procedures is evaluated. For the basic scheme of delegation mandates are used, for more advanced schemes, as the complexity in- creases, use of delegation assertions is proposed.

- KonferenzbeitrageVoting with the European Citizen Card(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Meister, Gisela; Hühnlein, Detlef; Eichholz, Jan; Araújo, RobertoAs many European countries are about to introduce national ID cards, which are compliant to the European Citizen Card specification [CEN15480] it is natural to study how those cards may be used to implement secure electronic vot- ing schemes. For this purpose we introduce a modified variant of the electronic voting scheme introduced in [JCJ05] which may be used with European Citizen Cards.
- KonferenzbeitragPerformance Evaluation of Multibiometric Face Recognition Systems(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Castro Neves, Margarida; Chindaro, Samuel; Ng, Ming; Zhou, Ziheng; Deravi, FarzinThe 3D Face project investigates the use of 3D face recognition technologies, and aims to improve their performance so that it would be possible to use such technologies in unsupervised access control scenarios in airports. During this project novel sensors, 2D, 3D, skin texture matchers and fusion algorithms have been developed. A technology performance test has been performed on all algorithms, in order to evaluate the technology improvements. This paper describes the independent test and evaluation activities for this project and gives an overview of the results obtained.
- Editiertes Buch3D measurement of human faces for biometric application by digital fringe projection with digital light projection (DLP)(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Benderoth, Christian; Yan, Jun; Hooshiar, Kavon; Bell, Rebecca L.; Frankowski, GottfriedFacial recognition of people can be used for the identification of individuals, or can serve as verification e.g. for access controls. The process requires that the facial data is captured and then compared with stored reference data. In order to obtain better identification and verification performance and to avoid a number of security weaknesses, 3-dimensional facial recognition systems can be used, which outperform in both cases the 2-dimensional systems that are currently used. In this context, an optical 3D face scanning system with structured light projection based on DMD will be introduced, and the performance of the system will be analysed.
- KonferenzbeitragInternational Database of Facial Images for Performance and ISO/IEC 19794-5 Conformance Tests(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Ebinger, Peter; Castro Neves, Margarida; Salamon, René; Seibert, HelmutDigital face images and fingerprint images are included in all newly issued EU passports [Bus06]. Face images stored within electronic passports (ePass) have to conform to ISO/IEC 19794-5 [Inta] which defines a number of quality requirements for facial image data. A software application (QS Software) is used to verify photographic image properties (pose, head/image size, height-to-page ratio, etc.) as well as setup properties (color depth, contrast, brightness, etc.) [Intb]. To ensure reliability and reproducibility of automated facial image processing systems it is necessary to assess the quality of existing software packages. To this end a database of facial image data would be of significant value as a testing base [HSM06]. The goal for project series FIReBIRD (Facial Image REcognition Benchmark In- cluding Realistic Disturbances) is to establish a database of facial images that can be used worldwide for compliance and performance testing and quality verification based on ISO standards. FIReBIRD will be conducted in close cooperation of Fraunhofer IGD and the German Federal Office for Information Security (BSI) and will be carried out in parallel and in international cooperation with the U.S. National Institute of Stan- dards and Technology (NIST) and the British National Physical Laboratory (NPL). After successful completion of a conceptual framework the international database will be built. This facial image database will consist of distinct data sets used by two separate user groups for two different purposes: public test data that is available for algorithm developers and non-public test data for system evaluation accessible only to authorized organizations such as BSI/Fraunhofer IGD, NPL and NIST.
- KonferenzbeitragImproving Border Control with 3D Face Recognition(BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Welti, Paul; Suchier, Jean-Marc; Busch, ChristophBiometric data have been integrated in all new European passports, since the member states of the European Commission started to implement the EU Council Regulation No 2252/2004 on standards for security features and biometrics in passports. The additional integration of three-dimensional models promises significant performance enhancements for border controls. By combining the geometry- and texture-channel information of the face, 3D face recognition systems provide an improved robustness while processing variations in poses and problematic lighting conditions when taking the photo. To assess the potential of three-dimensional face recognition, the 3D Face project was initiated. This paper outlines the approach, research objectives and achievements of this project: Not only shall the recognition performance be increased but also a new, fake resistant acquisition device have been developed and are currently tested. In addition,methods for protection of the stored template data in the biometric reference are under development.
