Fingerprint verification for smart-card holders based on an optical image encryption scheme
Optical Information Systems, 2003Co-Authors: Hiroyuki Suzuki, Taiga Yamaya, Takashi Obi, Masahiro Yamaguchi, Nagaaki OhyamaAbstract:Fingerprint verification for smart card holders is one of the methods which are able to identify smart card holders with a high level of security. However, an ingenious implementation is needed to execute it in the embedded processor quickly and safely, because of its computational burden and the limitation of the smart card performance. For this purpose, we propose a hybrid method which is a combination of personal identification number (PIN) verification with a smart card and an optical fingerprint verification method. The result of a preliminary computer simulation to evaluate the proposed system shows that false acceptance rate is completely zero, though false rejection rate is a little inferior to the conventional figerprint verification system.

Database on Danish population-based registers for public health and welfare research.
Scandinavian journal of public health, 2011Co-Authors: Camilla Sortsø, Lau Caspar Thygesen, Henrik Brønnum-hansenAbstract:Population-based studies with information from registers can take place in Denmark due to linkage between registers at the individual level by means of a unique personal identification number (CPR-number), which all persons with residence in Denmark have. Registers with information on health can be linked to other population registers containing information on, for example, transfer payments, education, housing, income, and socioeconomic position. This article introduces a database and search engine, which is available for public health and welfare researchers as an aid to seek information on the content of important Danish registers.

Introduction to Danish (nationwide) registers on health and social issues: Structure, access, legislation, and archiving
Scandinavian journal of public health, 2011Co-Authors: Lau Caspar Thygesen, Camilla Daasnes, Ivan Thaulow, Henrik Brønnum-hansenAbstract:Danish registers contain information on many important health and social issues. Because all Danish citizens have a unique personal identification number, linkage at the individual level between these nationwide registers and other data sources is possible and feasible. In this paper we briefly introduce selected Danish registers and the data structure and requirements for getting access to data at Statistics Denmark, which is the main provider of register data. We introduce the Danish Data Archive and briefly present the Act on Processing of personal Data, which is the legal foundation for analyses of register-based data in Denmark.

Danish population-based registers for public health and health-related welfare research: introduction to the supplement.
Scandinavian journal of public health, 2011Co-Authors: Lau Caspar Thygesen, Annette Kjær ErsbøllAbstract:Denmark and other Nordic countries have exceptional opportunities to perform register-based research, because of the unique personal identification number available to all persons with permanent residence [1]. This number makes it possible to link information at the individual level from several registers for investigation of various research questions. The unique personal identification number was introduced in Denmark in 1968, which enables follow-up of individuals for decades. This supplement of the Scandinavian Journal of Public Health presents public health and health-related registers and health-related welfare research based on Danish nationwide registers. The topics range from presentations of important registers, to introduction to the Danish legal foundations for register-based research, to short reviews of selected applications of registers for public health research. Linkage of the Danish registers is based on three base registers including identification numbers for persons, businesses, and real estates (Figure 1). All three base registers have linking keys to related registers and also to the other base registers. The linking keys are: the personal identification number (CPR-number) [1], the business identification number (SE/CVR-number) [2], and the building and housing identification number (BBR-number) [3]. The Civil Registration System contains the CPRnumber and includes references to parents and spouses, making it possible to establish the family unit. The Business Register contains the SE/CVRnumber of all businesses. The Building and Housing Register (BBR) contains the BBR-number, which identifies all unique housing unities. By the base registers it is possible to link persons, businesses and housing units. The aim of the supplement is to present a wide range of Danish registers and register-based research. We invited Danish key researchers performing register-based research to contribute to this supplement. Thus, this publication also highlights that registerbased research in Denmark is widely distributed at various research institutions and that registers are fundamental data sources in health and healthrelated welfare research. Twenty two institutes and departments at four Danish universities and 21 Danish administrative and research institutions contributed to the papers in this supplement. The supplement has three sections. The first section gives an overview of Danish registers, briefly introduces how to get access to data at Statistics Denmark and the legal foundation for register-based research. The section also presents an online database, which gives further information and an overview of the content of various Danish registers. This database also includes a search engine to help researchers to get more details on register contents. The second section includes presentations of important Danish registers on health and social factors. All papers have the same format, including four sections – in the Introduction section the background and rationale for establishing the register, the current purpose and historical pioneers are presented. In the Content section information on central variables in the register is provided and changes in variables and content, in reporting to the

HCI (22) - SafetyPIN: Secure PIN Entry Through Eye Tracking
Lecture Notes in Computer Science, 2015Co-Authors: Mythreya Seetharama, Volker Paelke, Carsten RöckerAbstract:When a user enters a personal identification number PIN into an automated teller machine or a point of sale terminal, there is a risk of some one watching from behind, trying to guess the PIN code. Such shoulder-surfing is a major security threat. In order to overcome this problem different PIN entry methods have been suggested. In this regard, gaze interaction methods are receiving attention in recent years, owing to the lowering cost of eye tracking technology. In this paper, we present SafetyPIN - an eye tracking based PIN entry system - which is aimed at making the PIN entry more secure with the help of an eye tracking device. We discuss the implementation and the initial evaluation of this system.
