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(More)
In this paper, there is introduced an approach to surface reconstruction of an object captured by one grayscale camera with a small resolution. The proposed solution expects a rectangular grid being projected onto the object and the camera capturing the situation from position different to the grid projector position. The crucial part of the method is exact(More)
This paper deals with a new approach for detection of finger veins. The method is split into four subsequent steps. The first of them consists of basic series of image filtering of the vein pattern and the other three are sequences of image filters for determination of the finger contour used for the background masking. At the end the finger veins with(More)
Der Beitrag geht der Frage nach, ob und wie biometrische Eigenschaften (Fingerabdruck und Stimme) als „biometrischer Schlüssel“ für die Kryptografie verwendet werden können. Dazu ist es wesentlich, Merkmale zu wählen, die sowohl über ausreichende Entropie als auch genügend „Stabilität“ verfügen, um die Wiedergewinnung des Schlüsselmaterials sicher zu(More)
