Social acceptance of biometric technologies in Germany: A survey
Since the past decade biometric technologies are field-proven, facilitating reliable and secure access control. Numerous successful deployments on large-scale systems, e.g. airports, confirm the feasibility of biometric recognition. However, applications of biometric systems involve privacy concerns, i.e. debates on ...
A preliminary study on the feasibility of storing fingerprint and iris image data in 2D-barcodes
Investigation of better portable graphics compression for iris biometric recognition
In this paper we present the very first study on the effectiveness of the recently proposed Better Portable Graphics (BPG) image compression algorithm in the context of iris recognition. Original and pre-processed iris images of the IITDv1 iris database are compressed at various reasonable bitrates and the impact of BPG ...
Improved fuzzy vault scheme for alignment-free fingerprint features
The fuzzy vault scheme is one of the most prominent tools for protecting fingerprint templates, typically being minutiae-based. However, there exist two major problems. Firstly, the fuzzy vault scheme is vulnerable to attacks correlating different templates of the same user. Secondly, auxiliary alignment data may leak ...
Visible Wavelength Iris Segmentation: A Multi-Class Approach using Fully Convolutional Neuronal Networks
BIOSIG 2018 - Proceedings of the 17th International Conference of the Biometrics Special Interest Group
Iris segmentation under visible wavelengths (VWs) is a vital processing step for iris recognition systems operating at-a-distance or in non-cooperative environments. In these scenarios the presence of various artefacts, e.g. occlusions or specular reflections, as well as out-of-focus blur represents a significant challenge. ...
