    Biometrie - Beschleuniger oder Bremser von Identitätsdiebstahl
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Busch, Christoph
    Der Beitrag betrachtet die Fragestellung, ob Biometrie als Beschleuniger oder Bremser von Identitätsdiebstahl betrachtet werden sollte. Dazu werden Szenarien betrachtet, in denen umfangreich Gesichtsbilddaten gesammelt werden. Diese Szenarien werden anhand etablierter Definitionen analysiert. Ferner werden Vorfälle von Identitätsmissbrauch betrachtet und eine Bewertung von Schutzmechanismen gegeben.

    Challenges for the implementation and revision of international biometric standards demonstrated by the example of face image data
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Ebinger, Peter; Neves, Margarida Castro; Salamon, René; Bausinger, Oliver
    Travel documents such as the electronic passport (ePass) ensure that each person can be uniquely identified by a single document. The development of new ePass security chip technologies allows for the inclusion of biometric properties in the data carrier of the ePass. The International Civil Aviation Organization (ICAO) has determined a personal photograph as being the interoperable feature for all global travel documents; ICAO [Gro04] regulations reference quality requirements for facial images as defined in ISO standard ISO/IEC 19794-5 [Intb]. Project FIReBIRDs goal is to prepare an international facial image database for conformity tests based on ISO/IEC 19794-5 [Intb], to analyze the requirements in the regulating documents, and to develop suggestions for adaptations and extensions of these standards. The FIReBIRD database shall provide a well-defined ground truth for level 3 conformance testing. For this purpose the specifications in the standard were thoroughly analyzed and in some parts refined to allow for a precise definition of ground truth. We show with two examples that there might be a defined common-sense definition for some parameters, but they are not measurable and their specification is not scientifically founded: the definition of full frontal view and the definition of eye and hair colors. Our results show that specifications and requirements should always be checked for necessity, practicability and usability and that a continued review and revision of biometric standards is necessary.

    Classification of skin diseases and their impact on fingerprint recognition
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Drahanský, Martin; Březinová, Eva; Orság, Filip; Lodrová, Dana
    This article describes different skin diseases which could have the influence to the process of fingerprint acquirement. There are many people, who suffer under such diseases and are therefore excluded from the set of users of a biometric system and could not e.g. get a visa to the USA or use an access biometric system installed in a company, where they work.

    The extended access control for machine readable travel documents
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Chaabouni, Rafik; Vaudenay, Serge
    Machine Readable travel documents have been rapidly put in place since 2004. The initial standard was made by the ICAO and it has been quickly followed by the Extended Access Control (EAC). In this paper we discuss about the evolution of these standards and more precisely on the evolution of EAC. We intend to give a realistic survey on these standards. We discuss about their problems, such as the inexistence of a clock in the biometric passports and the absence of a switch preventing the lecture of a closed passport. We also look at the issue with retrocompatibility that could be easily solved and the issue with terminal revocation that is harder.

    The fuzzy vault for fingerprints is vulnerable to brute force attack
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Mihǎilescu, Preda; Munk, Axel; Tams, Benjamin
    The fuzzy vault approach is one of the best studied and well accepted ideas for binding cryptographic security into biometric authentication. We present in this paper a brute force attack which improves on the one described by T. Charles Clancy et. al. in 2003 in an implementation of the vault for fingerprints. Based on this attack, we show that three implementations of the fingerprint vault are vulnerable and show that the vulnerability cannot be avoided by mere parameter selection in the actual frame of the protocol. We will report about our experiences with an implementation of such an attack. We also give several suggestions which can improve the fingerprint vault to become a cryptographically secure algorithm. In particular, we introduce the idea of fuzzy vault with quiz which draws upon information resources unused by the current version of the vault. This may bring important security improvements and can be adapted to the other biometric applications of the vault.

    Minutiae interoperability
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Tabassi, Elham; Grother, Patrick; Salamon, Wayne; Watson, Craig
    Many large scale identity management applications require storage and exchange of standardized minutiae templates. Minutia templates offer a more spaceefficient, less resource intensive, and more cost effective alternative to raw images. Recent minutiae interoperability tests (ILO, MTIT, MINEX ) all reported variation in minutia selection and placement as the major factor affecting interoperability. This paper quantifies their effects and investigates how variation in selection and placement of minutia from different suppliers relates to loss of performance compared with proprietary templates. We concur with MTIT findings that conformance testing methodologies for evaluating the semantic content of minutia templates is essential and interoperability can be improved by closer adherence to the minutia placement requirement defined in a standard.

    Multi-sample fusion with template protection
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Kelkboom, Emile J. C.; Breebaart, Jeroen; Veldhuis, Raymond N. J.; Zhou, Xuebing; Busch, Christoph
    The widespread use of biometrics and its increased popularity introduces privacy risks. In order to mitigate these risks, solutions such as the helper-data system, fuzzy vault, fuzzy extractors, and cancelable biometrics were introduced, also known as the field of template protection. Besides these developments, fusion of multiple sources of biometric information have shown to improve the verification performance of the biometric system. Our work consists of analyzing feature-level fusion in the context of the template protection framework using the helper-data system. We verify the results using the FRGC v2 database and two feature extraction algorithms.

    A note on the protection level of biometric data in electronic passports
    (BIOSIG 2009: biometrics and electronic signatures, 2009) Baier, Harald; Straub, Tobias
    Following regulations of the EU Council in 2004, the member states have deployed electronic passports according to ICAO standards. Such documents contain an embedded radio frequency chip for storing personal data. The chip of a first generation German passport only duplicates the information which is already printed on the passport. In the current second version there are now also two fingerprints as additional biometric attributes apart from the digital facial image of the document owner. The note at hand concentrates on attack vectors of biometric characteristics contained in the RF chip and discusses which threats towards fingerprints are thwarted. Our gist is to point to the low protection level of the facial image on the one hand and the high protection level of fingerprints on the other hand although both biometric characteristics are easy to gather.
