Apple claims that iPhone 6, which is equipped with iOS 8.0 and later version, is secure enough to prevent a user's private data from law enforcement or malicious intruders. In pre-iOS 8.0 operating systems, a user's data were only encrypted by hardware-based keys, which can be obtained by Apple. But in iOS 8.0 and later version, the private data on the iPhone are protected by a secret key that is...
Delaunay triangulation based structures, e.g., the Delaunay triangle and Voronoi neighbor structure, have been utilized in fingerprint authentication due to their desirable features in terms of dealing with non-linear distortion and spurious and missing minutiae. However, no existing research has shed light on the effect of spurious and missing minutiae on Delaunay triangulation when it is applied...
In this paper, we aim to shed some light on the benefits and challenges brought about by using biometrics for securing mobile payments. Some potential solutions to address the challenges are also proposed and analyzed. Based on our analysis, it is shown that biometric cryptosystems are the suitable choice for providing security protection to biometric templates and enabling a seamless integration...
Lack of the capability of cancellability in a biometric cryptosystem makes it impossible to be deployed broadly in real applications. This is because the compromise of a template in one application often means its loss in all other applications. To solve this problem, we equip a minutiae-based fuzzy vault with cancellability by applying a polar transformation to each Delaunay triangle group so as...
The problem of recognizing an individual using minutiae of fingerprints can be considered as a point matching problem. However, several factors such as the translation, rotation and deformation of the fingerprints as well as the presence of spurious minutiae and the absence of genuine minutiae, make it difficult to find correspondent minutia-pairs. In this paper, we proposed a novel topology-based...
Bio-cryptography is a new security technology which combines cryptography with biometrics. Fuzzy extractors are effective in terms of binding a cryptographic key to biometric features. However, most existing fuzzy extractors require fingerprint registration prior to the application of fuzzy extractors, and depend on error-correction codes to rectify the biometric uncertainty. This is not operative...
Hierarchy-based wireless sensor networks (WSNs) achieve excellent performance with reserving energy consumption and decreasing system delay. However, distinguished hierarchy-based research such as LEACH (low-energy adaptive clustering hierarchy) does not consider a security issue for ensuring the protection of the network. Due to the peculiar character of LEACH such as round base operation and header...
Nowadays, there has been an explosive growth in the research devoted to the area of hierarchical architecture for its extraordinary performance on energy-saving and special applications. However, because the nature of security threats in wireless sensor networks (WSNs) as well as the nature of WSN itself raises additional security challenges, new schemes and architectures are needed to prevent the...
