Correlation-resistant fuzzy vault for fingerprints
Sicherheit 2016 - Sicherheit, Schutz und Zuverlässigkeit
The fuzzy vault is one of the most popular biometric encryption schemes for protecting fingerprint data. However, its implementation faces two challenges: First, the fingerprints need to be aligned. Some publications have proposed the storage of auxiliary data to assist alignment, but these data may leak information about ...
Predicting Dactyloscopic Examiner Fingerprint Image Quality Assessments
We work towards a system which can assist dactyloscopic examiners in assessing the quality and decision value of a fingerprint image and eventually a fingermark. However when quality assessment tasks of datyloscopic examiners are replaced by automatic quality assessment then we need to ensure that the automatic measurement ...
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 ...
Protected Honey Face Templates
Most existing biometric template protection schemes (BTPS) do not provide as strong security as cryptographic tools; and furthermore, they are rarely able to detect during a verification process whether a probe template has been leaked from the database or not (i.e., being used by an imposter or a genuine user). By using ...
A fingerprint indexing scheme with robustness against sample translation and rotation
Automatic fingerprint identification systems (AFIS) are getting prevalent around the world, and the size of fingerprint databases involved in AFIS is continuously growing. Thus, studying fingerprint indexing algorithms is desirable in order to facilitate the search process in a large-scale database. In this paper, we ...
Decision robustness of voice activity segmentation in unconstrained mobile speaker recognition environments
The influence of fingerprint image degradations on the performance of biometric system and quality assessment
