Computational Intelligence Anti-Malware Framework for Android OS

Konstantinos Demertzis, Lazaros Iliadis
Journal Papers Special Issue on "Vietnam Journal of Computer Science (VJCS)", Springer, DOI 10.1007/s40595-017-0095-3


It is a fact that more and more users are adopting the online digital payment systems via mobile devices for everyday use. This attracts powerful gangs of cybercriminals, which use sophisticated and highly intelligent types of malware in order to broaden their attacks. Malicious software is designed to run quietly and to remain unsolved for a long time. It manages to take full control of the device and to communicate (via the Tor network) with its Command & Control (C & C) servers of fast-flux botnets’ networks to which it belongs. This is done in order to achieve the malicious objectives of the botmasters. This paper proposes the development of the Computational Intelligence Anti-Malware Framework (CIantiMF) which is innovative, ultra-fast and it has low requirements. It runs under the Android Operating System (OS) and its reasoning is based on advanced Computational Intelligence approaches. The selection of the Android OS was based on its popularity and on the number of critical applications available for it. The CIantiMF uses two advanced technology extensions for the ART JVM (Java Virtual Machine) which is the default in the recent versions of Android. The first is the Smart Anti-Malware Extension (SAME), which can recognize whether the Java classes of an Android application are benign or malicious by using an optimized Multi-Layer Perceptron (MLP). The optimization is done by the employment of the Biogeography-Based Optimizer algorithm (BBO). The second is the Tor Online Traffic Identification Extension (OTTIE), which is capable of achieving malware localization, Tor traffic identification and botnets prohibition, with the use of the Online Sequential Extreme Learning Machine (OSELM) algorithm.

Detecting Invasive Species with a Bio-Inspired Semi Supervised Neurocomputing Approach: The Case of Lagocephalus Sceleratus

Konstantinos Demertzis, Lazaros Iliadis
Journal Paper Special issues Neural Computing and Applications journal by Springer, DOI :10.1007/s00521-016-2591-2


The need to protect the environment, biodiversity and to safeguard public health requires the development of timely and reliable methods for the identification of particularly dangerous invasive species, before they become regulators of ecosystems. These species appear morphologically similar, despite their strong biological differences, something that complicates their identification process. Additionally, the localization of the broader space of dispersion and development of invasive species is considered of critical importance, in an effort to take the proper management measures. The aim of this research is to create an advanced computational intelligence system for the automatic recognition, of invasive or other unknown species. The identification is performed based on the analysis of environmental DNA (eDNA) by employing machine learning methods. More specifically, this research effort proposes a hybrid bio-inspired computational intelligence detection approach. It employs Extreme Learning Machines combined with an evolving Izhikevich spiking neuron model, for the automated identification of the extremely dangerous for human health invasive fish species “Lagocephalus Sceleratus”.

Soft Computing Modeling of Wild Fire Risk Indices: The Risk Profile of Peloponnesus Region in Greece

It is essential to find ways that can reduce the risk of devastating forest fires which have multiple negative ecological and financial consequences. This preliminary research effort focuses on the implementation of an intelligent rule based fuzzy inference system evaluating wild fire risk in the forest departments of Greece. The system uses soft computing techniques and was built in the Matlab integrated environment. The whole research is related to the wild fires in Greece during the period 1983-1997 with data coming from the general forest management service. It classifies all Greek forest departments (by assigning three labels) according to their forest fire risk due to distinct parameters. The estimation of the risk indices was done by using fuzzy triangular membership functions and Einstein fuzzy conjunction T-Norms. Moreover the system produces the profile of the forest departments located in the geographic area of “Peloponnesus.” This is a region located in the southern part of the country and it has a vast number of annual forest fire breakouts. Meteorological, topographic, and historical (total burned area and intervention time) features were considered for the determination of the risk indices. The system has shown a good performance which can be improved further if more data is gathered and used. Its main advantage is that it offers an innovative and reliable model that can be employed in any part of the world as a basis for natural disasters’ risk estimation.

Developing neural networks to investigate relationships between air quality and quality of life indicators

Quality of life (QOL) is an integral outcome measure in the management of diseases. It can be used to assess the results of different management methods, in relation to disease complications and in fine-tuning management methods (Koller & Lorenz, 2003). Quantitative analysis of quality of life across countries, and the construction of summary indices for such analyses have been of interest for some time (Slottje et al., 1991). Most early work focused on largely single dimensional analysis based on such indicators as per capita GDP, the literacy rate, and mortality rates. Maasoumi (1998) and others called for a multidimensional quantitative study of welfare and quality of life. The argument is that welfare is made up of several distinct dimensions, which cannot all be monetized, and heterogeneity complications are best accommodated in multidimensional analysis. Hirschberg et al. (1991) and Hirschberg et al. (1998) identified similar indicators, and collected them into distinct clusters which could represent the dimensions worthy of distinct treatment in multidimensional frameworks. In this research effort we have considered the role of air quality indicators in the context of economic and welfare life quality indicators, using artificial neural networks (ANN). Therefore in this presentation we have obtained the key variables (life expectancy, healthy life years, infant mortality, Gross Domestic Product (GDP) and GDP growth rate) and developed a neural network model to predict the air quality outcomes (emissions of sulphur and nitrogen oxides). Sustainability and quality of life indicators have been proposed recently by Flynn et al. (2002) and life quality indices have been used to estimate willingness to pay (Pandey & Nathwani, 2004). The innovative part of this research effort lies in the use of a soft computing machine learning approach like the ANN to predict air quality. In this way, we introduce the reader to a technique that allows the comparison of various attributes that impact the quality of life in a meaningful way.

Fast and low cost prediction of extreme air pollution values with hybrid unsupervised learning

Ilias Bougoudis, Konstantinos Demertzis,Lazaros Iliadis
Journal Paper Journal: Integrated Computer-Aided Engineering, vol. 23, no. 2, pp. 115-127, 2016


Air pollution is the problem of adding harmful substances or other agents into the atmosphere and it is caused by industrial, transport or household activities. It is one of the most serious problems of our times and the determination of the conditions under which we have extreme pollutants' values is a crucial challenge for the modern scientific community. The innovative and effective hybrid algorithm designed and employed in this research effort is entitled Easy Hybrid Forecasting (EHF). The main advantage of the EHF is that each forecasting does not require measurements from sensors, other hardware devices or data that require the use of expensive software. This was done intentionally because the motivation for this work was the development of a hybrid application that can be downloaded for free and used easily by everyday common people with no additional financial cost, running in devices like smart phones. From this point of view it does not require data from sensors or specialized software and it can offer people reliable information about extreme cases.

AOne of the direct consequences of climate change lies in the spread of invasive species, which constitute a serious and rapidly worsening threat to ecology, preservation of natural biodiversity and protection of flora and fauna. It can even be a potential threat to the health of humans. These species, do not appear to have serious morphological variations, despite their strong biological differences. Due to this fact their identification process is often quite difficult. The need to protect the environment and safeguard public health, requires the development of advanced methods for early and accurate identification of some particularly dangerous invasive species, in order to plan and apply specific and effective management measures. The aim of this study is to create an advanced computer vision system for the automatic recognition of invasive or other unknown species, based on their phenotypes. More specifically, this research proposes an innovative and very effective Extreme Learning Machine (ELM) model, which is optimized by the Adaptive Elitist Differential Evolution algorithm (AEDE). The AEDE is an improved version of the differential evolution (DE) algorithm and it is proper for big data resolution. Feature selection is done by using deep learning Convolutional Neural Networks. A Geo Location system is used to detect the invasive species by Comparing with the local species of the region under research.

Several machine learning models were used to predict interior spruce wood density using data from open-pollinated progeny testing trial. The data set consists of growth (height and diameter which were used to estimate individual tree volume) and wood quality (wood density determined by X-ray densitometry, resistance to drilling, and acoustic velocity) attributes for a total of 1,146 trees growing on comparable sites in interior British Columbia. Various machine learning models were developed for estimating wood density. The Multi Layer Feed Forward (MLFF) artificial neural networks and Gene Expression Programming (GEP) provided the highest predictability as compared to the other methods tested, including those based on classical multiple regression which was considered as the comparisons benchmark. The utilization of machine learning models as a credible method for estimating wood density using available growth data as an indirect method for determining trees wood density is expected to become increasingly helpful to forest managers and tree breeders.

The analysis of air quality and the continuous monitoring of air pollution levels are important subjects of the environmental science and research. This problem actually has real impact in the human health and quality of life. The determination of the conditions which favor high concentration of pollutants and most of all the timely forecast of such cases is really crucial, as it facilitates the imposition of specific protection and prevention actions by civil protection. This research paper discusses an innovative three folded intelligent hybrid system of combined machine learning algorithms HISYCOL (henceforth). First it deals with the correlation of the conditions under which high pollutants concentrations emerge. On the other hand it proposes and presents an ensemble system using combination of machine learning algorithms capable of forecasting the values of air pollutants (VAP). What is really important and gives this modeling effort a hybrid nature is the fact that it uses clustered datasets. Moreover this approach improves the accuracy of existing forecasting models by using unsupervised machine learning to cluster the data vectors and trace hidden knowledge. Finally it employs a Mamdani fuzzy inference system for each air pollutant in order to forecast even more effectively its concentrations.

Air pollution is directly linked with the development of technology and science, the progress of which besides significant benefits to mankind it also has adverse effects on the environment and hence on human health. The problem has begun to take worrying proportions especially in large urban centers, where 60,000 deaths are reported each year in Europe's towns and 3,000,000 worldwide, due to long-term air pollution exposure (exposure of the European Agency for the Environment In this paper we propose a novel and flexible hybrid machine learning system that combines Semi-Supervised Classification and Semi-Supervised Clustering, in order to realize prediction of air pollutants outliers and to study the conditions that favor their high concentration.

Air pollution is related to the concentration of harmful substances in the lower layers of the atmosphere and it is one of the most serious problems threatening the modern way of life. Determination of the conditions that cause maximization of the problem and assessment of the catalytic effect of relative humidity and temperature are important research subjects in the evaluation of environmental risk. This research effort describes an innovative model towards the forecasting of both primary and secondary air pollutants in the center of Athens, by employing Soft Computing Techniques. More specifically, Fuzzy Cognitive Maps are used to analyze the conditions and to correlate the factors contributing to air pollution. According to the climate change scenarios till 2100, there is going to be a serious fluctuation of the average temperature and rainfall in a global scale. This modeling effort aims in forecasting the evolution of the air pollutants concentrations in Athens as a consequence of the upcoming climate change.

Intelligent Bio-Inspired Detection of Food Borne Pathogen by DNA Barcodes: The Case of Invasive Fish Species Lagocephalus Sceleratus

Conference Papers Engineering Applications of Neural Networks, Volume 517 of the series Communications in Computer and Information Science pp 89-99, 16th International Conference, EANN 2015, Rhodes, Greece, September 25-28 2015.Proceedings, DOI 10.1007/978-3-319-23983-5_9, Springer International Publishing


Climate change combined with the increase of extreme weather phenomena, has significantly influenced marine ecosystems, resulting in water overheating, increase of sea level and rising of the acidity of surface waters. The potential impacts in the biodiversity of sensitive ecosystems (such as Mediterranean sea) are obvious. Many organisms are under extinction, whereas other dangerous invasive species are multiplied and thus they are destroying the ecological equilibrium. This research paper presents the development of a sophisticated, fast and accurate Food Pathogen Detection (FPD) system, which uses the biologically inspired Artificial Intelligence algorithm of Extreme Learning Machines. The aim is the automated identification and control of the extremely dangerous for human health invasive fish species “Lagocephalus Sceleratus”. The matching is achieved through extensive comparisons of protein and DNA sequences, known also as DNA barcodes following an ensemble learning approach.

SAME: An Intelligent Anti-malware Extension for Android ART Virtual Machine

Conference Papers Computational Collective Intelligence, Volume 9330 of the series Lecture Notes in Computer Science pp 235-245, 7th International Conference, ICCCI 2015, Madrid, Spain, September 21-23, 2015, Proceedings, Part II, DOI 10.1007/978-3-319-24306-1_23, Springer International Publishing


It is well known that cyber criminal gangs are already using advanced and especially intelligent types of Android malware, in order to overcome the out-of-band security measures. This is done in order to broaden and enhance their attacks which mainly target financial and credit foundations and their transactions. It is a fact that most applications used under the Android system are written in Java. The research described herein, proposes the development of an innovative active security system that goes beyond the limits of the existing ones. The developed system acts as an extension on the ART (Android Run Time) Virtual Machine architecture, used by the Android Lolipop 5.0 version. Its main task is the analysis and classification of the Java classes of each application. It is a flexible intelligent system with low requirements in computational resources, named Smart Anti Malware Extension (SAME). It uses the biologically inspired Biogeography-Based Optimizer (BBO) heuristic algorithm for the training of a Multi-Layer Perceptron (MLP) in order to classify the Java classes of an application as benign or malicious. SAME was run in parallel with the Particle Swarm Optimization (PSO), Ant Colony Optimization (ACO) and Genetic Algorithm (GA) and it has shown its validity.

Domain Generation Algorithm (DGA) has evolved as one of the most dangerous and “undetectable” digital security deception methods. The complexity of this approach (combined with the intricate function of the fast-flux “botnet” networks) is the cause of an extremely risky threat which is hard to trace. In most of the cases it should be faced as a zero-day vulnerability. This kind of combined attacks is responsible for malware distribution and for the infection of Information Systems. Moreover it is related to illegal actions, like money mule recruitment sites, phishing websites, illicit online pharmacies, extreme or illegal adult content sites, malicious browser exploit sites and web traps for distributing virus. Traditional digital security mechanisms phase such vulnerabilities in a conventional manner, they create often false alarms and they fail to forecast them. This paper proposes an innovative fast and accurate evolving Smart URL Filter (eSURLF) in a Zone-based Policy Firewall (ZFW) which uses evolving Spiking Neural Networks (eSNN) for detecting algorithmically generated malicious domains names.

Confidentiality, Integrity and Availability of Military information is a crucial and critical factor for a country’s national security. The security of military Information Systems (MIS) and Networks (MNET) is a subject of continuous research and design, due to the fact that they manage, store, manipulate and distribute the information. This study presents a Bio-Inspired Hybrid Artificial Intelligence Framework for Cyber Security (bioHAIFCS). This framework combines timely and bio inspired Machine Learning methods suitable for the protection of critical network applications namely military information systems, applications and networks. More specifically, it combines a) the Hybrid Evolving Spiking Anomaly Detection Model (HESADM), which is used in order to prevent in time and accurately, cyber-attacks, which cannot be avoided by using passive security measures namely: Firewalls, b) the Evolving Computational Intelligence System for Malware Detection (ECISMD) that spots and isolates malwares located in packed executables untraceable by antivirus c) the Evolutionary Prevention System from SQL Injection (ePSSQLI) attacks, which early and smartly forecasts the attacks using SQL Injections methods.

According to the Greek mythology, Ladon was the huge dragon with the 100 heads, which had the ability to stay continuously up, in order to guard the golden “Esperides” apples in the tree of life. Alike the ancient one, digital Ladon is an advanced information systems’ security mechanism, which uses Artificial Intelligence to protect, control and offer early warning in cases of detour or misleading of the digital security measures. It is an effective cross-layer system of network supervision, which enriches the lower layers of the system (Transport, Network and Data). It amplifies in an intelligent manner the upper layers (Session, Presentation and Application) with capabilities of automated control. This is done to enhance the energetic security and the mechanisms of reaction of the general system, without special requirements in computational resources. This paper describes the development of Ladon which is an advanced, incredibly fast and low requirements’ effective filter, that performs analysis of network flow. Ladon uses Online Sequential Extreme Learning Machine with Gaussian Radial Basis Function kernel in order to perform network traffic classification, malware traffic analysis and fast-flux botnets localization.
