Patient Privacy Protection Using Anonymous Access Control Techniques

TL;DR: The proposed protocol protects the patient privacy with a secure anonymous authentication to healthcare services and medical record registries according to the European and the UK legislations, where the patient real identity is not disclosed with the distributed patient medical records.
Proceedings ArticleDOI

Privacy in Mobile Web Services eHealth

TL;DR: A novel architecture that integrates 3GPP UMTS mobile technology with Web services is proposed that will help address authentication and privacy concern within eHealth environment.
Journal ArticleDOI

Optical sensor for pH monitoring using a layer-by-layer deposition technique emphasizing enhanced stability and re-usability

TL;DR: In this paper, the performance of three different stabilization approaches used for the development of an effective wavelength-dependent pH-sensitive optical sensor was compared and an improvement in performance and in shelf-life, stability and reusability of the sensor was achieved by the addition of two bilayers of APTMS/SiO2 (3-Aminopropyl-trimethoxy silane/Silica nanoparticle) in the work carried out and the results of the investigation undertaken are reported.
Proceedings ArticleDOI

SmartARM: A smartphone-based group activity recognition and monitoring scheme for military applications

TL;DR: This work establishes the optimum position of smartphone placement on a soldier, the optimum classifier to use from a given set of options, and the minimum sensors or sensor combinations to use for reliable detection of physical activities, while reducing the data-load on the network.
Journal ArticleDOI

Ransomware detection using deep learning based unsupervised feature extraction and a cost sensitive Pareto Ensemble classifier

TL;DR: In this article , a cost-sensitive Pareto ensemble strategy, CSPE-R, was proposed to detect zero-day ransomware attacks by exploiting the unsupervised deep Contractive Auto Encoder (CAE) to transform the underlying varying feature space to a more uniform and core semantic feature space.
