In this paper, a new paradigm of user authentication called “wireless key” is described. Following this concept, a novel many-to-many authentication scheme based on passive NFC tags is proposed. In contradiction to existing solutions that assume a wireless key to be a battery-powered device with considerable computational power, we suggest to use a passive NFC tag in order to minimise the key size and significantly reduce the costs. The security of all the information on the tag is guaranteed by a specific data encryption scheme constructed on top of strong cryptographic primitives. In our approach, all the computations are performed by the service user is authenticating in, and thus no computational power and no battery on the key side is needed. This comes to an user-friendly, secure and cost-efficient solution. Moreover, the system core - proposed encryption scheme - could be easily applied to any other carrier technologies, as, for example, to Bluetooth Low Energy or Wireless USB. Having generalised our solution to hold an integrity property, it can also be used for another emerging application - secure documents storage.

This paper introduces a variety of analog computing elements utilizing dynamics of DNA strand displacement reactions. In the proposed method, the establishment of functional relationship between the concentrations of inputs and those of outputs at the steady state is regarded as computation. We will propose analog versions of an amplifier, an adder, a multiplier, a divider and a constant gate, which are time responsive. Some further discussion will be made toward the construction of controllers for molecular robots.

Introduction: The ECG Bayesian filtering framework has been shown to be a promising method to extract the foetal electrocardiogram (FECG) from abdominal recordings. This framework requires an estimation of the ECG morphology, which is obtained by approximating an average beat with a number of Gaussian kernels. This approximation results in a high dimensional nonlinear optimization problem (finding ideal positions, width and height for these kernels). Methods: Proposed methodologies in the literature initialize the optimization algorithm using fixed positions for the kernel functions. This contribution benchmarks alternative schemes for finding the Gaussian parameters, namely an approach based on the stationary wavelet transform and random search. The goal is minimizing the normalized mean squared error between the average beat and the approximated model, while increasing foetal QRS detection accuracy. Results: The suggested methods are able to produce improved morphology approximations of the averaged beat up 4.05% (depending on the selected method). The proposed method using the stationary wavelet transform improves the goodness of the fit, while reducing the computational load. However, no immediate improvement on the accuracy of FQRS detections was noticed. Such findings render the proposed method a promising tool. However, further research should be directed at transferring the improved fit to an improvement of FQRS detections.

Visual Data Mining (VDM) is supported by interactive and scalable network visualization and analysis, which in turn enables effective exploration and communication of ideas within multiple biological and biomedical fields. Large networks, such as the protein interactome or transcriptional regulatory networks, contain hundreds of thousands of objects and millions of relationships. These networks are continuously evolving as new knowledge becomes available, and their content is richly annotated and can be presented in many different ways. Attempting to discover knowledge and new theories within this complex data sets can involve many workflows, such as accurately representing many formats of source data, merging heterogeneous and distributed data sources, complex database searching, integrating results from multiple computational and mathematical analyses, and effectively visualizing properties and results. Our experience with biology researchers has required us to address their needs and requirements in the design and development of a scalable and interactive network visualization and analysis platform, NAViGaTOR, now in its third major release. © Springer-Verlag Berlin Heidelberg 2014.

A multiuser dual-hop relaying system over mixed radio frequency/free-space optical (RF/FSO) links is investigated. Specifically, the system consists of m single-antenna sources, a relay node equipped with n≥ m receive antennas and a single photo-aperture transmitter, and one destination equipped with a single photo-detector. RF links are used for the simultaneous data transmission from multiple sources to the relay. The relay operates under the decode-and-forward protocol and utilizes the popular V-BLAST technique by successively decoding each user's transmitted stream. Two common norm-based orderings are adopted, i.e., the streams are decoded in an ascending or a descending order. After V-BLAST, the relay retransmits the decoded information to the destination via a point-to-point FSO link in m consecutive timeslots. Analytical expressions for the end-to-end outage probability and average symbol error probability of each user are derived, while closed-form asymptotic expressions are also presented. Capitalizing on the derived results, some engineering insights are manifested, such as the coding and diversity gain of each user, the impact of the pointing error displacement on the FSO link and the V-BLAST ordering effectiveness at the relay. © 1972-2012 IEEE.

2014 4th IEEE International Conference on Information Science and technology

This paper proposes a distributed node election algorithm to efficiently select a subset of nodes which provide full coverage. In addition the boundary of un-triangulated holes can be accurately detected. This algorithm only uses binary connectivity information without any additional information such as sensing range or distance between nodes. Assumptions of a Unit Disk Graph(UDG) or d-quasi UDG network configuration are not required. The number of elected nodes is close to the minimum number of nodes for full coverage as shown in simulations with arbitrary topologies and various densities. The algorithm is scalable to any network size. Its time complexity is only sensitive to the density of the network(or average number of neighbors for each node) and is insensitive to the total number of nodes in the network.

Facial Expression Recognition is the subsequent step after Face Detection and Real time recognition of facial expressions is a challenging task. Various technologies of Facial Expression Recognition has been experimented by researchers over the past few years. In this paper, it has been observed the accuracy and effectiveness of employing Active Shape Models and Support Vector Machines to achieve higher recognition rates. Active Shape Model is used to locate the facial feature deformations of a face detected by using Haar classifiers. These facial coordinates are fed into a Support Vector Machine and the trained system classifies the expressions into seven categories, namely happy, sad, anger, disgust, fear, surprise and neutral. The system was tested on JAFFE Database and Cross Validation had been used as a mechanism for analysing the results of the experiment. © 2013 IEEE.

There is an issue when security measures are implemented and tested while using agile software development techniques such as Behavior Driven Development (BDD). We need to define the necessary levels of security and the privacy behaviors and acceptance criteria for the BDD. A method for defining the acceptance criteria (BehaveSafe) by creating a threat and countermeasure graph called theT&C graph is proposed in this paper. We have estimated the efficiency of our method with a web based system. © Springer International Publishing Switzerland 2014.
