Research ArticleOpen accessAll words, across the recordInformation Hiding using Chaotic-Address SteganographyOla N. Kadhim, Zahir M. HussainIn this study, two techniques are introduced for imagesteganography in the spatial domain. These systems employ chaos theory to trackthe addresses of shuffled bits in steganography. The first system is based onthe well-known LSB technique, while the second system is based on a recentapproach that searches for the identical bits between the secret message andthe cover image. A modified logistic … …Journal of Computer Science, Vol. 14, Issue 9 · 27 Sep 2018 · 7,681 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Visible and Near Infrared Polarized Lights on Spoofing Face DetectionAzim Zaliha Abd AzizFace spoofing countermeasure is vital to avoid an imposter from gaining access to security biometric systems by using face masks in various forms that mimic a valid user face. Recently, several studies have shown the ability of visible polarized light in distinguishing real and fake faces. In this paper, polarization imaging systems using visible and near infrared (NIR) are proposed … …Journal of Computer Science, Vol. 15, Issue 2 · 23 Feb 2019 · 7,893 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordINTRUSION DETECTION SYSTEM IN SECURE SHELL TRAFFIC IN CLOUD ENVIRONMENTMehdi Barati, Azizol Abdullah, NurIzura Udzir et al.Due to growth of Cloud computing usage, the need to apply encrypted protocols to provide confidentiality and integrity of data increases dramatically. Attacker can take advantage of these protocols to hide the intrusion and evade detection. Many traditional attack detection techniques have been proposed to provide security in the networks but none of them can be implemented properly in encrypted … …Journal of Computer Science, Vol. 10, Issue 10 · 26 Jun 2014 · 7,851 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGeographical Division Traceback for Distributed Denial of ServiceA. Viswanathan, V. P. Arunachalam, S. KarthikProblem statement: Distributed Denial of Service (DDoS) was a serious threat to the internet world that denies the legitimate users from being access the internet by blocking the service. Approach: In this study, we proposed a novel approach, Geographical Division Traceback (GDT) for efficient IP traceback and DDoS defense methodology. DDoS attack was one of the most serious and threatening … …Journal of Computer Science, Vol. 8, Issue 2 · 23 Nov 2011 · 7,129 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIntrusion Preventing System using Intrusion Detection System Decision Tree Data MiningSyurahbil, Noraziah Ahmad, M. Fadly Zolkipli, Ahmed N. AbdallaProblem statement: To distinguish the activities of the network traffic that the intrusion and normal is very difficult and to need much time consuming. An analyst must review all the data that large and wide to find the sequence of intrusion on the network connection. Therefore, it needs a way that can detect network intrusion to reflect the current network … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,337 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Integration of Network-Based Models for Spill Response and Homeland SecurityDavid E. Amstutz, Rakesh Bahadur, Jonathan M. Pickus et al.The integration of three hydraulic GIS (Geographic Information System) applications is presented which represent the water infrastructures of cities and urban areas and US streams and rivers. The water infrastructures include drinking water distribution systems, wastewater collection systems and source water. The National Research Council[1] states that problems dealing with the collective behavior of networks such as river systems, water … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,729 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Optimization Approach for Selecting Blocks of Embedding Process in Robust Watermarking SystemAbabneh M.F. Mohammad, Naseem M. AsadThis study, discusses several kinds of attacks that may meet the watermarked image such as JPEG compression, Gaussian noise and median filter. The study introduces an approach capable of selecting the optimal blocks in cover image to be used in embedding process. Also, in this study, we propose a technique in robust digital watermarking system looking for finding a relation … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,171 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordReal-Time Multimodal Biometric User Authentication for Web Application Access in Wireless LANSanjay Kumar, Surjit Paul, Dilip Kumar ShawWeb applications store trustworthy information and can be accessed online through wired or wireless network. Authentication is one of the major challenges to access these web applications. With varying level of sensitive data stored in web application, the concept of level of authentication can be introduced using biometric traits. This paper proposes biometric-based multi-modal authentication system with four levels of … …Journal of Computer Science, Vol. 13, Issue 12 · 26 Sep 2017 · 7,465 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordSurvey on Representation Techniques for Malware Detection SystemGamal Abdel Nassir Mohamed, Norafida Bte IthninMalicious programs are malignant software’s designed by hackers or cyber offenders with a harmful intent to disrupt computer operation. In various researches, we found that the balance between designing an accurate architecture that can detect the malware and track several advanced techniques that malware creators apply to get variants of malware are always a difficult line. Hence the study of … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 10 Jul 2017 · 8,582 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordGeneration Test-Cases of Attacks in Mobile Ad Hoc NetworkSara Chadli, Mohammed Saber, Abdelhak ZiyyatThe number and increasing complexity of attacks against MANETs have grown significantly in recent years. While many security proposals have been developed. However, these proposals suffer from the problems of tests and evaluations. Among these solutions, the Intrusion Detection Systems (IDS) that can act as defense mechanisms. However, this last poses serious problems for its evaluators that need classify the … …Journal of Computer Science, Vol. 12, Issue 10 · 14 Dec 2016 · 6,522 accessesView PDFCite
