Title of the Paper: Enhancing Liveness Detection Methods in Iris Codes for Iris Recognition
Authors: J. Vijayaraj, D. Loganathan
Pages: 79-87
Abstract: Iris Recognition methodology is anauthentication mechanism that combines the various methodology. It is used to increase the accuracy of the iris detection method. Iris recognition has inherent weaknesses that can potentially compromise the security of a system. Parodying attacks is one of them and enhanced iris recognition is more vulnerable to parody attack than normal iris recognition method. Parodying is giving duplicate input to the biometric sensor. Parody detection is used to check whether the given input is original or duplicate. The objective is to overcome parodying attacks in iris recognition method. The proposed methodology extracts a set of features from iris using mean, median, variance and local ternary pattern (LTP) techniques respectively and the extracted biometric features are fused and fed to a convolution neural network that employs deep learning to detect parodied features from original features. The proposed method gives better results than the existing liveness detection methods in iris recognition.

Title of the Paper: Consumption Temporary Density for the Detection of Water Leakages in Real-time
Authors: Anissa Ticherahine, Soumia Bourebia, Abdenacer Makhlouf, Patrice Wira
Pages: 68-74
Abstract: Detecting water leakage is a major challenge. Usually, specific meters are used to monitor water consumption. However, conventional meters are not capable of detecting an abnormal consumption such as an eventual leak. Due to recent advances in technologies and the emergence of the Internet of Things paradigm, a new kind of smart water meter has appeared. These meters provide further options for monitoring water consumption. In this paper, a new water leakage indicator, called Water Leakage Indicator based on the Consumption Temporary Density (WLICTD), is presented. The leakage detection process is based on a computation of temporal density for water consumption. WLICTD can distinguish an abnormal consumption, i.e., a leak situation, from a normal daily consumption. The proposed indicator has been evaluated using a set of real water consumption data obtained from a smart meter installed in a university restaurant in France. Results reveal the strength and efficiency of the proposed indicator in detecting all water leaks situations within a convenient period of time.
Title of the Paper: High-phase Resolution Architecture for Phased Array Transmitters
Authors: F. Cannone, G. Avitabile, G. Coviello
Pages: 59-67
Abstract: The paper describes a frequency independent phase shifting technique suitable for applications wherein a high-phase resolution at RF frequencies is required. For instance the propose approach is useful both for advanced measurements systems and for RADAR, satellite and wireless telecommunications systems. The proposed phased array transmitter is based on an innovative technique using the cascade of two blocks: an advanced digital block named Phase Control Block and an up-converter block containing integer-PLLs. The first digital block assures a high phase resolution comparable with the precision achievable by using a Direct Digital Synthesizer. The second block allows the up conversion at microwaves frequencies without a significant decrease of the phase-shift precisions. In fact, thanks to the described technique, the phase resolution is limited only by the rms phase error introduced by the integer-PLLs. The theory governing the design of the phase shifter is thoroughly discussed and three prototypes operating in different bands reporting an rms phase error lower than 0.4 degrees are reported. The measurements are compared with theoretical results showing a perfect agreement

Pages: 37-41
Abstract: Simple Network Management Protocol (SNMP) is a popular protocol for network management. It is used for collecting information from, and configuring, network devices.This standardization gives network administrators the ability to monitor network performance. In this paper, we highlight to analyze the correctness and authenticity of SNMP using the formal method Event-B and the Rodin Tool to verify the accuracy of our protocol's performance. Event-B is formal technique that enables user to express the problem at abstract level and then add more details in refinement step to obtain concrete specification. This interaction between modelling and proving reduces the complexity and helps in assuring that the SNMP specification is correct and unambiguous.

Two models have been developed: a tutor-student model showing the activities of the learner and tutor, and moderating-member-secretary model that focuses more specifically on the roles of the moderator (coordinator) and the secretary (rapportor). This modeling has made it possible to better understand the processes considered and to detect the various problems that may arise during an online particle work collaborative process.
Title of the Paper: Moving Object Tracking based on Camshift Algorithm
Authors: Md. Shaiful Islam Babu, K. H. Shaikh Ahmed
Pages: 8-11
Abstract: Continuously adaptive Camshift is an efficient and lightweight tracking algorithm developed based on mean-shift. Camshift algorithm has the advantage of better real-time, but this algorithm is only suitable for tracking targets in simple cases, not well for tracking desired targets in complex situation. In this paper, we will present an improved method of multiple targets tracking algorithm based on the Camshift algorithm combined with Kalman filter. The tracker of the improved method was used to track each detected target. It can achieve tracking of multiple targets. A large number of experiments have proved that this algorithm has strong target recognition ability, good anti-noise performance, and fasttracking speed.
Title of the Paper: Designing a Decentralized Container based Fog Computing Framework for Task Distribution and Management
Authors: Anna Reale, Peter Kiss, Melinda Toth, Zoltan Horvath
Pages: 1-7
Abstract: In the field of Fog computing, because of the highly dynamic nature of Mobile Networks, the problem of automating task distribution and code migration has not yet been solved by any resource orchestrator. In this paper, we propose a solution to the problem in the form of an orchestrator that can build overlay computational networks from a volatile set of nodes. Each node of this overlay is able to deploy specific services and can satisfy the requested task from any participant node. We also demonstrate the infrastructure purpose by suggesting an existing Federated Learning Application.
