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 ...
Simulation of Print-Scan Transformations for Face Images based on Conditional Adversarial Networks
BIOSIG 2020 - Proceedings of the 19th International Conference of the Biometrics Special Interest Group
In many countries, printing and scanning of face images is frequently performed as part of the issuance process of electronic travel documents, e.g., ePassports. Image alterations induced by such print-scan transformations may negatively effect the performance of various biometric subsystems, in particular image manipulation ...
