Title:	ENHANCEMENT OF AES ALGORITHM BASED ON CHAOTIC MAPS AND SHIFT OPERATION FOR IMAGE ENCRYPTION
Author:	ALI ABDULGADER, MAHAMOD ISMAIL, NASHARUDDIN ZAINAL, TARIK IDBEAA
Abstract:	With the rapid development of the Internet and communication networks, the confidentiality of digital images transmitted over public networks must be preserved by using encryption techniques. Advanced Encryption Standard (AES) is one of the most commonly used encryption algorithms at present. Although AES has several advantages, such as security in data encryption, it also has a number of drawbacks, such as high computations, pattern problems when used for encrypting images, and fixed S-box weak points. This paper proposes a method that overcomes the fixed S-box weak points and improves the performance of AES when used for encrypting images, particularly when the image data are large. In addition, the MixColumn stage is replaced by chaotic mapping and XOR operation to reduce the high computations in MixColumn transform. The proposed method is tested on several images, and the results show that the proposed method efficiently generated cipher images with very low correlation coefficients of adjacent pixels and provided better encryption speed and high security as a result of the dependence of the S-box on the key characteristics of the chaotic system.
Keywords:	AES, S-Box, Cyclic Shifting Operation, Inverse S-Box, Round Key, Chaotic Map.

Title:	HIGH PERFORMANCE GAMELAN ANALYZER USING ADAPTIVE WAVEFORM PATTERN MATCHING
Author:	YOYON K. SUPRAPTO, VINCENTIUS E. PRADHANA
Abstract:	Exploration of the eastern music such as gamelan is very rare, so its development is far lagged to western music. Estimation of fundamental frequencies and estimation of the envelope are needed to determine the performance of traditional music instrument. We applied Waveform Adaptive Pattern Matching (WAPM) to estimate fundamental frequency which is detected with limited frequency band.The fundamental frequency is estimated by very short recorded gamelan music signal of 45 ms, with accuracy of 0.25 Hz. Besides the fundamental frequency estimation, the invention is useful gamelan tuning the signal envelope. This method is implemented in Android applications to analyze a signal gamelan, thus enhance the portability of the application.
Keywords:	Gamelan Music, Fundamental Frequency, Waveform Adaptive Pattern Matching, Minimum Absolute Error, Android.

Title:	SECURITY POLICIES MATCHING THROUGH ONTOLOGIES ALIGNMENT TO SUPPORT SECURITY EXPERTS
Author:	OTHMAN BENAMMAR, HICHAM ELASRI, MOSTAFA JEBBAR and ABDERRAHIM SEKKAKI
Abstract:	The management of security policies has become increasingly difficult for the security expert given the number of domains to manage their extent and their complexity. A security expert has to deal with a variety of frameworks, with different language specifications, formalization and aspect used in domains that may belong to any Cloud Computing or Distributed Systems. This wealth of frameworks and languages make the management task and the interpretation of the security policies so hardly difficult. Each approach provides its own conflict management method or tool, the security expert will be forced to manage all these tools, which makes the field maintenance and time consuming expensive. In order to hide this complexity and to facilitate and automate some security expert’s tasks, we propose a security policies aligning based on ontologies process; this process enables to detect and resolve security policies conflicts and to support security experts in managing tasks.
Keywords:	Security-Based Policy; Security Management; Ontology Alignment; Ontology Enrichment; Conflicts Resolution Method.

Author:	NUR SHAZWANI KAMARUDIN, MOKHAIRI MAKHTAR, , SYED ABDULLAH FADZLI, MUMTAZIMAH MOHAMAD, FATMA SUSILAWATI MOHAMAD, MOHD FADZIL ABDUL KADIR
Abstract:	This paper presents the technique for the classification of single object images. First, this paper aims to introduce the efficient technique in order to classify single object image. Second, each single methods uses in order to propose the techniques were elaborated in this paper. It start from image segmentation, object identification, feature extraction, feature selection and classification. Finally, the best classifier that can provide the best results were identified. The efficiency of the proposed method is define by comparing the result of classification using two different datasets from author’s previous paper. The obligation for development of image classification has been improved due to remarkable growth in volume of images, as well as the widespread application in multiple fields. This paper explores the process of classifying images by the categories of object in the case of a large number of object categories. The use of a set of features to describe 2D shapes in low-level images has been proposed. The proposed technique aims a short and simple way to extract shape description before classifying the image. Using the Caltech 101 object recognition benchmark, classification was tested using four different classifiers; BayesNet, NaiveBayesUpdateable, Random Tree and IBk. Estimated accuracy was in the range from 58% to 99% (using 10-cross validation). By comparing with Amazon data, it is proved that the proposed model is more suitable for single object image. Amazon images give higher accuracy with the range from 80% to 99.48%.

Title:	HIGH PERFORMANCE IMPLEMENTATION OF RSSI BASED WI-FI LOCATION TRACKER FOR ANDROID APPLICATIONS
Author:	S.A. YUVARAJ, and Dr.L.C.SIDDANNA GOWD
Abstract:	Wi-Fi-based positioning system (WPS) is used where GPS is inadequate due to various causes including multipath and signal blockage indoors. Such systems include indoor positioning systems. The advantage of choosing Wi-Fi for a location based service is its high compatibility and frequency of availability. The majority of today’s smart phones also have Wi-Fi connectivity. Newer revisions of Wi-Fi broadcast at the 2.4 GHz frequency, allowing for signals to more easily travel through obstructions like doors and walls. Unlike other wireless technologies such as Bluetooth, Wi-Fi incorporates signal strength functions into all the firmware drivers and Application Programming Interfaces (APIs) which are defined by the manufacturers and backed by IEEE.2 This feature will provide a large benefit when using Wi-Fi to determine a location based on signal strength triangulation. The localization technique used for positioning with wireless access points is based on measuring the intensity of the received signal strength (RSSI). Typical parameters useful to geo-locating the Wi-Fi hotspot or wireless access point include the SSID and the MAC address of the access point. The accuracy depends on the number of positions that have been entered into the database. The possible signal fluctuations that may occur can increase errors and inaccuracies in the path of the user. To minimize fluctuations in the received signal, there are certain techniques that can be applied to filter the noise. The Mobile Nodes will have featured Wi-Fi capabilities and the processing power to deliver accurate results. The Nodes will scan all known access points that in range and determine the signal strength in dBm (or dBmW) and get there respective MAC address. The access point’s MAC address is compared against a database of known access point locations. All of the quantified location coordinates are saved and the location of the each Node is obtained. The more available access points, the more accurate the location reading will be. We are using only 3 access points to obtain the (x,y) coordinate values/location of the mobile device. The calculated position will be displayed in graphical format.

Title:	RECOGNITION OF HUMAN ACTIVITIES FROM STILL IMAGE USING NOVEL CLASSIFIER
Author:	GHAZALI SULONG , AMMAR MOHAMMEDALI
Abstract:	The quest for recognizing human activities and categorizing their features from still images using efficient and accurate classifier is never ending. This is more challenging than extracting information from video due to the absence of any prior knowledge resembling frames stream. Human Activities Recognition (HAR) refers to computer identification of specific activities to aid understanding of human behaviors in diversified applications such as surveillance cameras, security systems and automotive industry. We developed a novel model for classifier and used it in three main stages including preprocessing (foreground extraction), segmentation (background subtraction) to extract useful features from object and sort out these features by the classifier (classification). The model is further simulated using MATLAB programming. Our new classifier generates slightly different results for still image based on dataset INRIA and KTH for 780 images of (64*128) pixels format obtained from literature. The recognition rate of 86.2% for five activities such as running, walking, jumping, standing and sitting achieved by us is highly promising compared to the existing one of 85% over last decade.

Author:	BAHAREH NAKISA, MOHAMMAD NAIM RASTGOO, MOHAMMAD FAIDZUL NASRUDIN, MOHD ZAKREE AHMAD NAZRI
Abstract:	This paper proposes a method based on the Multi-Swarm Particle Swarm Optimization (PSO) with Local Search on the multi-robot search system to find a given target in a Complex environment that contains static obstacles. This method by applying Multi-Swarm with Multi-Best particles on the multi-robot system can overcome the premature convergence problem, which is one of the main problems of Basic PSO. As the time progress the global searching of the algorithm decrease and therefore the robots tend to get group together in the small-explored region that called Premature Convergence and cannot reach the target. By combining the Local Search method with Multi-Swarm, We can guarantee the global convergence of this proposed algorithm and the robots can reach the target. The Experimental results obtained in a simulated environment show that biological and sociological inspiration could be useful to meet the challenges of robotic applications that can be described as optimization problems.

Title:	PATTERN-BASED SYSTEM TO DETECT THE ADVERSE DRUG EFFECT SENTENCES IN MEDICAL CASE REPORTS
Author:	SAFAA ELTYEB , NAOMIE SALIM
Abstract:	The detection of adverse drug effect sentences in medical text reduces the efforts required for the manual task of drug safety monitoring by decreasing the number of reports which need to be investigated by drug safety experts. Moreover it helps in compiling a highly accurate and machine-understandable drug related adverse effects knowledge bases which can support pharmacovigilance research and aids computational approaches for drugs repurposing. In this study, we proposed a pattern-based method to detect the sentences containing drug-adverse effect causal relation from medical case reports. A set of 500 full abstracts from Medline medical case reports containing 988 adverse drug effect sentences from ADE corpus were used to evaluate the sentences detection task. Our method combined an outcome of a concept recognition system with a method for automatic generation of numerous patterns. Our method achieved recall of 72.8, precision of 93.6 and F-Score of 81.7 % in the adverse drug effect sentences detection task . The results of this study can help database curators in compiling medical databases and researchers to digest the huge amount of textual information which is growing rapidly. Moreover, the mining algorithms developed in this study can be employed to detect sentences contain new associations between other medical entities in medical text.
