A CAPTCHA – BASED INTRUSION DETECTION MODEL
No full textIntrusion Detection systems (IDS) are an essential element for Network Security Infrastructure and play an important role in detecting large number of attacks. Intrusion Prevention System (IPS) is a tool that is used to prevent spywares from getting intrusion into a system and one of the techniques used in IPS is Completely Automated Public Turning test to tell Computers and Human Apart (CAPTCHA). In order to detect illegal access of the web from the intruder, IDS, IPS can be implemented with the use of honeypot to track the IP address, location and country or region of the attacker in order to block the attacker from accessing the system. Different techniques have been adopted by different researchers using IDS, IPS and honeypot to protect their system against illegal attacks. As discovered in the existing systems CAPTCHA was not employed in IDS to detect spywares capable of breaking and having access to the system. To increase and maintain the security in a Network the combination of IDS with CAPTCHA, IPS and a dummy Honeypot can be employed. This work proposes a CAPTCHA –based Intrusion Detection Model with a redirector in order to identify the intelligent spywares that are capable of breaking CAPTCHA in IPS. Also using a dummy honeypot with circular hyperlinks so as to lewd the software that infiltrated the system in order to capture its IP address and other important information about the spywares such as the country or region it’s coming from, web browser used and date and time of intrusion so as to block and prevent illegal access by intruders. This paper focuses on capturing the intelligent spywares capable to break through the new CAPTCHA trap IDS so as to gather information about it and necessary action can be taken against it. A security model was designed having having CAPTCHA IDS with a redirector, IPS and a honeypot cable of detecting intrusion by intelligent spyware With this model the network will be more secured against intrusion by spyware
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A Framework for Privacy and Hate Speeches Control on Social Media in Mobile Computing
Get PDFThe hype in information technology has led to the use of mobile devices to carry out several activities such as financial transactions, communications, learning and other related activities using the internet. Social networking platforms today are used to facilitate the activities carried out on mobile devices. The use of these social network platforms such as Facebook, Twitter, Whatsapp, Snapchat, Instagram among others on mobile devices is called mobile social network. A mobile social network makes it faster and easier for users to relate to one another and carry out other related activities at convenience. The major challenge with the use of social network applications on mobile devices is that, many illegal activities are carried out such as hate speeches and bigotry statement which has demeaning the interest of users. This research work proposes a technique for discovering and blocking hate speeches and bigotry users on social network platforms using text scanning and matching algorithm; in order to curtail the damages caused to national security and unity by such statement. Keywords: Mobile social network, social network
Performance Analysis of Text and Image Steganography with RSA Algorithm in Cloud Computing
No full textDispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
