		ePassport: The World’s New Biometric Passport One and a half years after publishing the very first book about the world’s new electronic passport ‘ePassport’, Jöran Beel, Ivo Rössling and I published a completely overworked version of our book in English. The new book ‘ePassport: The World’s New Biometric Passport’ describes the basic details of the ePassport, gives a thorough overview of the technical specifications and then provides an in-depth analysis considering both, chances and risks of the new technology. Beside the explanation and analysis of biometric passports in general the introduction of the ePassport in Germany is considered in particular. Among others the book shows that some fears of data protectionists are unsubstantiated. On the other hand, the book reveals disinformation by the German Government and that the security of the Basic Access Control usually is significantly lower than the promoted 56 Bit.

		ePass – der neue biometrische Reisepass This book is about the electronic passport which is called ‘ePass’ in Germany. The electronic passport is compulsory for all EU-citizens within the next years and other countries such as the United States or Australia are also introducing it. The book covers all relevant topics of the electronic passport such as security concepts, biometrics, digital signatures, encryption and data privacy. Also political aspects are considered. Since the book has been published in October 2005 it became the standard book about the ePass. Newspapers, researchers, ePass opponents and ePass proponents in Germany base their work on this book.

abstract = {Various approaches for plagiarism detection exist. All are based on
more or less sophisticated text analysis methods such as string matching,
fingerprinting or style comparison. In this paper a new approach
called Citation-based Plagiarism Detection is evaluated using a doctoral
thesis, in which a volunteer crowd-sourcing project called GuttenPlag
identified substantial amounts of plagiarism through careful manual
inspection. This new approach is able to identify similar and plagiarized
documents based on the citations used in the text. It is shown that
citation-based plagiarism detection performs significantly better
than text-based procedures in identifying strong paraphrasing, translation
and some idea plagiarism. Detection rates can be improved by combining
citation-based with text-based plagiarism detection.},

note = {Available at http://gipp.com/pub},
abstract = {Jedes Jahr sterben auf deutschen Strassen 7.000 Menschen durch Verkehrsunfaelle.
Davon koennten ueber 700 vor dem Tod bewahrt werden, wenn die Rettungsdienste
unverzueglich nach dem Unfall informiert wuerden. Leider kommt es
immer wieder vor, dass Verunfallte erst nach Minuten oder gar Stunden
gefunden werden und so wertvolle Zeit bis zur Benachrichtigung der
Rettungskraefte verstreicht. Warum nicht das flaechendeckend verfuegbare
Mobilfunknetz nutzen, um automatisch Hilfe herbeizuholen? Urspruenglich
im Rahmen von Jugend-forscht entwickelten wir in den vergangenen
zwei Jahren ein flexibles und kostenguenstiges Notrufsystem - den
"GSM Schutzengel". Dieser sieht aus wie ein gewoehnlicher Mobiltelefonakku,
enthaelt aber zusaetzlich einen Beschleunigungssensor und einen Mikrokontroller
zum Auswerten der Messdaten. Mit dieser Technik ist es moeglich,
jedes handelsuebliche Mobiltelefon zu einem mobilen Schutzengel aufzuruesten,
der Unfaelle sicher erkennt. Fehlalarme, beispielsweise durch Vollbremsungen
waehrend der Autofahrt oder Hinunterfallen des Mobiltelefons, sind
dabei ausgeschlossen. Bei einem Unfall ruft der GSM Schutzengel sofort
die Rettungskraefte herbei. Dadurch kann selbst bewusstlosen Fahrern
schnellstmoeglich geholfen werden. Die Position des Unfalls wird
dabei ueber das Mobilfunknetz bestimmt - bis auf 150 m genau. Somit
kann zielgenaue Hilfe gewaehrleistet werden, denn wer kann schon
direkt nach einem Unfall beschreiben, wo genau er ist?}

Lawinenhunde geleistet haben, muss in Zeiten des Massen-Tourismus
mit technischem Know-how geloest werden. Die Idee von Bela Gipp,
Jan-Olaf Stiller und Florian Krueger: Ein System, bei dem eine Infrarotkamera
von einem Modellhubschrauber aus Bilder an ein Leitsystem weitergibt,
auf dem sich die Temperaturunterschiede zwischen warmen Koerpern
und Schnee erkennen lassen. Zur Orientierung des Hubschraubers dient
eine zusaetzliche Echtfarbkamera, ein Ultraschallgeraet fuer schlechte
Sicht und ein Global Positioning System (GPS). Alles kann mit einem
Programm, das die jungen Erfinder geschrieben haben, ueber das Internet
gesteuert und ausgewertet werden."
