Abstract In this paper we summarize our first research results in the field of Cross Culture user authentication. We will investigate intercultural aspects of biometrics, both of(More)
OBJECTIVE To investigate the different effects of hypertension, hyperlipidaemia and atherosclerosis on the visco-elastic properties of large arteries. DESIGN Vessel wall properties were determined in patients who had been subjected for the first time to coronary arteriography. Normotensive patients with no coronary disease (n = 15), one-vessel disease (n(More)
The relation between lipoprotein(a) [Lp(a)] as an independent risk factor for coronary atherosclerosis and the severity and extension of angiographically detectable coronary atherosclerotic lesions has not been systematically evaluated. In 118 male patients (54.3 +/- 7.4 years) with suspected coronary artery disease and without a history of myocardial(More)
PURPOSE This study examines the relation between lipoprotein (a) protein levels and other lipid parameters and coronary artery disease in white and black patients. PATIENTS AND METHODS Plasma lipoprotein (a) protein levels were measured prior to coronary angiography in a population of 127 white and 111 black patients. Each angiogram was given a total(More)
In this paper a new approach for combining biometric authentication and digital watermarking is presented. A digital audio watermark method is used to embed metadata into the reference data of biometric speaker recognition. Metadata in our context may consist of feature template representations complementary to the speech modality, such as iris codes or(More)
Coronary events have a close association with a low HDL/hypertriglyceridemia (LHDL/HTG) phenotype. As enzymes that hydrolyze triglyceride-rich lipoproteins are associated with a modulation of both HDL cholesterol and triglycerides, we have tested the hypothesis that mutations in the genes encoding lipoprotein lipase (LPL) or hepatic lipase (HTGL) may(More)
Contrary to cryptographic hash functions, which calculate the same value for only the same input, biometric hash functions have to generate identical hashes from varying input data of the same person. In this paper a secure sketch method is suggested that was developed to generate hash values from dynamic handwritten data. The presented secure sketch method(More)
In this paper we visit annotation watermarking as a tool to embed information about a cover or parts thereof in the cover. We describe a framework for image annotation watermarking, especially Nested Object Annotation Watermarking. This was introduced in earlier works to embed not only textual and/or semantic descriptions as annotations but also their(More)
In this paper, we present an integrated research study in On-line Signature Verification undertaken by several teams that participate in the BioSecure Network of Excellence. This integrated work, started during the First BioSecure Residential Workshop, has as main objective the development of an On-line Signature Verification evaluation platform. As a first(More)
