Cryptanalysis of the Fuzzy Vault for Fingerprints: Vulnerabilities and Countermeasures by
BerendBenjamin Tams(

2 editions published between 2012 and 2013 in English and held by 22 WorldCat member libraries worldwide
Das Fuzzy Vault ist ein beliebter Ansatz, um die Minutien eines menschlichen Fingerabdrucks in einer Sicherheitsanwendung geschützt zu speichern. In dieser Arbeit werden verschiedene Implementationen des Fuzzy Vault für Fingerabdrücke in verschiedenen Angriffsszenarien untersucht. Unsere Untersuchungen und Analysen bestätigen deutlich, dass die größte Schwäche von Implementationen des Fingerabdruck Fuzzy Vaults seine hohe Anfälligkeit gegen FalseAccept Angriffe ist. Als Gegenmaßnahme könnten mehrere Finger oder sogar mehrere biometrische Merkmale eines Menschen gleichzeitig verwendet werde

A unified framework for spline estimators by
Katsiaryna Schwarz(
)
1 edition published in 2013 in English and held by 22 WorldCat member libraries worldwide
This dissertation develops a uni ed framework to study the (asymptotic) properties of all (periodic) spline based estimators, that is of regression, penalized and smoothing splines. The explicit form of the periodic DemmlerReinsch basis of general degree in terms of exponential splines allows to derive the exact expression for the equivalent kernel of all spline estimators simultaneously. The corresponding bandwidth, which drives the asymptotic behavior of spline estimators, is shown to be a function of both the number of knots and the smoothing parameter. A strategy for the optimal bandwi

Fourier and Variational Based Approaches for Fingerprint Segmentation by
Duy Hoang Thai(
)
2 editions published in 2015 in English and held by 17 WorldCat member libraries worldwide
Fingerprint recognition plays an important role in many commercial applications and is used by millions of people every day, e.g. for unlocking mobile phones. Fingerprint image segmentation is typically the first processing step of most fingerprint algorithms and it divides an image into foreground, the region of interest (ROI), and background. Two types of error can occur during this step and both have a negative impact on the recognition performance: 'true' foreground can be labelled as background and features like minutiae can be lost, or conversely 'true' background can be misclassified

A new approach to the investigation of Iwasawa invariants by
Sören Kleine(
)
2 editions published in 2014 in English and held by 17 WorldCat member libraries worldwide
Let K be a fixed number field, let p be a prime number, and let Z_p denote the additive group of padic integers. The growth of the pSylow subgroups of the ideal class groups of the intermediate fields in a Z_pextension L of K may be explicitly described in terms of the socalled Iwasawa invariants of L/K. In this thesis, we define a certain topology on the set of Z_pextensions of the number field K, and we prove that Iwasawa's invariants are locally maximal with respect to this topology. Furthermore, we develop necessary and sufficient criteria for the invariants to be globally bounded

Fingerprint Growth Prediction, Image Preprocessing and Multilevel Judgment Aggregation by
Carsten Gottschlich(
)
2 editions published between 2010 and 2011 in English and held by 14 WorldCat member libraries worldwide
Finger growth is studied in the first part of the thesis and a method for growth prediction is presented. The effectiveness of the method is validated in several tests. Fingerprint image preprocessing is discussed in the second part and novel methods for orientation field estimation, ridge frequency estimation and image enhancement are proposed: the line sensor method for orientation estimation provides more robustness to noise than state of the art methods. Curved regions are proposed for improving the ridge frequency estimation and curved Gabor filters for image enhancement. The notion of multilevel judgment aggregation is introduced as a design principle for combining different methods at all levels of fingerprint image processing. Lastly, score revaluation is proposed for incorporating information obtained during preprocessing into the score, and thus amending the quality of the similarity measure at the final stage. A sample application combines all proposed methods of the second part and demonstrates the validity of the approach by achieving massive verification performance improvements in comparison to state of the art software on all available databases of the fingerprint verification competitions (FVC)

Problemsolving and selected topics in number theory : in the spirit of the mathematical Olympiads by
Michael Th Rassias(
Book
)
3 editions published in 2011 in English and held by 3 WorldCat member libraries worldwide
This book is designed to introduce some of the most important theorems and results from number theory while testing the reader{u2019}s understanding through carefully selected Olympiadcaliber problems. These problems and their solutions provide the reader with an opportunity to sharpen their skills and to apply the theory. This framework guides the reader to an easy comprehension of some of the jewels of number theory The book is selfcontained and rigorously presented. Various aspects will be of interest to graduate and undergraduate students in number theory, advanced high school students and the teachers who train them for mathematics competitions, as well as to scholars who will enjoy learning more about number theory. Michael Th. Rassias has received several awards in mathematical problem solving competitions including two gold medals at the PanHellenic Mathematical Competitions of 2002 and 2003 held in Athens, a silver medal at the Balkan Mathematical Olympiad of 2002 held in Targu Mures, Romania and a silver medal at the 44th International Mathematical Olympiad of 2003 held in Tokyo, Japan

Christopher Daniel Ambrose(

2 editions published in 2014 in English and held by 3 WorldCat member libraries worldwide
Artins Vermutung über Primitivwurzeln besagt, dass es zu jeder ganzen Zahl a, die weder 0, ±1 noch eine Quadratzahl ist, unendlich viele Primzahlen p gibt, sodass a eine Primitivwurzel modulo p ist, d.h. a erzeugt eine multiplikative Untergruppe von Q*, dessen Reduktion modulo p Index 1 in (Z/pZ)* hat. Dies wirft die Frage nach Verteilung von Index und Ordnung dieser Reduktion in (Z/pZ)* auf, wenn man p variiert. Diese Arbeit widmet sich verallgemeinerten Fragestellungen in Zahlkörpern: Ist K ein Zahlkörper und Gamma eine endlich erzeugte unendliche Untergruppe von K*, so werden Momente von
