A Generic Framework for Three-Factor Authentication: Preserving Security and Privacy in Distributed Systems

Abstract: As part of the security within distributed systems, various services and resources need protection from unauthorized use. Remote authentication is the most commonly used method to determine the identity of a remote client. This paper investigates a systematic approach for authenticating clients by three factors, namely password, smart card, and biometrics. A generic and secure framework is proposed to upgrade two-factor authentication to three-factor authentication. The conversion not only significantly improves the information assurance at low cost but also protects client privacy in distributed systems. In addition, our framework retains several practice-friendly properties of the underlying two-factor authentication, which we believe is of independent interest.

Federated Internet of Things and Cloud Computing Pervasive Patient Health Monitoring System

Abstract: The exponentially growing healthcare costs coupled with the increasing interest of patients in receiving care in the comfort of their own homes have prompted a serious need to revolutionize healthcare systems. This has prompted active research in the development of solutions that enable healthcare providers to remotely monitor and evaluate the health of patients in the comfort of their residences. However, existing works lack flexibility, scalability, and energy efficiency. This article presents a pervasive patient health monitoring (PPHM) system infrastructure. PPHM is based on integrated cloud computing and Internet of Things technologies. In order to demonstrate the suitability of the proposed PPHM infrastructure, a case study for real-time monitoring of a patient suffering from congestive heart failure using ECG is presented. Experimental evaluation of the proposed PPHM infrastructure shows that PPHM is a flexible, scalable, and energy-efficient remote patient health monitoring system.

Charge-controlled switchable CO2 capture on boron nitride nanomaterials

Abstract: Increasing concerns about the atmospheric CO2 concentration and its impact on the environment are motivating researchers to discover new materials and technologies for efficient CO2 capture and conversion. Here, we report a study of the adsorption of CO2, CH4, and H2 on boron nitride (BN) nanosheets and nanotubes (NTs) with different charge states. The results show that the process of CO2 capture/release can be simply controlled by switching on/off the charges carried by BN nanomaterials. CO2 molecules form weak interactions with uncharged BN nanomaterials and are weakly adsorbed. When extra electrons are introduced to these nanomaterials (i.e., when they are negatively charged), CO2 molecules become tightly bound and strongly adsorbed. Once the electrons are removed, CO2 molecules spontaneously desorb from BN absorbents. In addition, these negatively charged BN nanosorbents show high selectivity for separating CO2 from its mixtures with CH4 and/or H2. Our study demonstrates that BN nanomaterials are exce...

Is it worth the effort? How feedback influences students’ subsequent submission of assessable work

Abstract: This paper explores the extent to which students appear to their assessors to act on feedback they have received, and questions the assumption that providing feedback alone is sufficient to effect higher standards of work by students. Feedback provided to 51 undergraduate social work students, on two consecutive assignments involving a similar task, was examined to ascertain the number of problem areas noted from seven predefined categories. While the greatest increase in marks was associated with the greatest reductions in the number of problem areas identified in the comments, overall two‐thirds of all students (66.7%) were awarded marks for both assignments within four percentage points. As such, this study found only limited support for the idea that students respond to feedback by making changes which are consistent with the intent of the feedback received. Hence the assumption that providing feedback alone is sufficient to effect higher standards of work by students was not supported. These findings...
