Abstract: Currently the digital images are used in various areas like medical, fashion, architecture, face recognition, finger print recognition and bio metrics. Recently the CBIR reduced the semantic gap between the low visual features and high level image semantics. In this paper we describe a novel framework for performing content-based image retrieval using Back Propagation Neural Network. Our method focuses on performing category search, though it could easily be ex- tended to other types of searches, and does not require relevance feedback in order to perform reasonably. It also emphasizes the importance of utilizing information collected from the sets of image database in medical system.

Title : Impact of Random Waypoint Mobility on Reactive Routing Protocols of Scalable Mobile Ad hoc Network
Country : India

Abstract : Mobile Ad hoc networks are the self-configuring network, in which there is no centralized access point. The mobile nodes itself act as routers for one another. MANET is basically a wireless ad hoc network with the routing capability. Scalability and Mobility have measure impact on the behavior of ad hoc routing protocols. Before deploying these protocols on the network, we must observe their performance under various circumstances. Simulation is a very effective and efficient technique for measuring their behavior in this decentralized infrastructure less network. This paper focuses on the characteristic measure of reactive routing protocols (DSR, AODV, DYMO, IERP and LAR1) for different criteria on application layer and transport layer of Internet .We compare the behavior of these protocols with the increasing number of nodes using Random Waypoint Mobility Model and taking pause time as the main criterion. Traffic load is constant and network load is varying in this analysis.

Abstract : Bluetooth Library Manager (BLM) is library management software which can be used in any library for maintaining different functions like book search, requisition submission, data entry etc. I have implemented this software on Android platform which has the advantage of portability and wide availability. I used Bluetooth as communication medium between the server and the client. BLM has additional capabilities (call, SMS, email) for communication between library card holder and the administration. I have implemented this specially for any educational institution which has a library having capacity not more than 20,000 users. An encryption algorithm is used to enhance the security of that software. This algorithm is used for the log-in purpose. Using the encryption algorithm we encrypt the password in the client side and the cipher-text and the username is send over Bluetooth to the server side. The decryption algorithm is used in the server side to decrypt the cipher-text. Then the decrypted password is matched with corresponding password of that user stored in the server side database. The user can successfully log-in into the system if and only if the password of the database matches with the decrypted password. The entire database of the library is implemented in a normalized way. Student can submit their requisition from there phone without using internet. They can contact their faculties and classmates via SMS, email or call and vice-versa. A student can check the availability using this software. She/he can also see the return-date of any book which is out of stock now and borrowed by another student. Faculties can also send any notification to any student via email or SMS.

Abstract : Data hiding involves hiding of information in a cover media to obtain the indistinguishable media, in such a way that the cover media is supposed not to have any embedded image for its unintended recipients. Steganography and Watermarking are main parts of the fast developing area of information hiding. This paper is based on Steganography, Watermarking and Cryptography where the system ensures secured image transfer between the source and destination. Encrypted image bits are embedded into higher and random LSB layers, resulting in increased robustness against noise addition. On the other hand, multi-objective Genetic Algorithm operators are used to reduce distortion. The basic idea of this paper is to improve security. For this improvement image embedding position numbers are converted to optimized Arrays and these Arrays are embedded into the Audio file. Performance based on imperceptibility, security and hiding capacity has been evaluated and discussed.

Abstract : Recent advances have given rise to the popularity and success of cloud computing. However, when outsourcing the data and business application to a third party causes the security and privacy issues to become a critical concern. Throughout the study at hand, the authors obtain a common goal to provide a comprehensive review of the existing security and privacy issues in cloud environments. We have identified five most representative security and privacy attributes (i.e., confidentiality, integrity, availability, accountability, and privacy-preservability). Beginning with these attributes, we present the relationships among them, the vulnerabilities that may be exploited by attackers, the threat models, as well as existing defense strategies in a cloud scenario. Future research directions are previously determined for each attribute.

Abstract : Decision trees are very significant for taking any type of verdict related to any field. Today there is ample amount of data but that data is uncooked data therefore to make it cooked data, data mining is done. Data mining concept has been used to enhance the quality of data. Various techniques are there in data mining for growth in information technology. Those techniques are classification; clustering, association rules etc. For classifying the data best method is to generate a decision tree. By using decision tree best decisions can be made as it is hierarchal structure which can be easy to interpret. A novel algorithm is implemented which gives results faster and has enhanced features than conventional algorithms of data mining. In new approach some features of Univariate algorithm (i.e. CART algorithm) and some features of Multivariate algorithm (i.e. M5P algorithm) plus an enhanced feature of new algorithm is included. The new feature of algorithm does enhancement in performance as using it performance is improved. In novel approach pruning of files is done due to which specific data can be accessed. Time is saved by using this algorithm and user can perform the task quickly and efficiently.

Title : Frequent Itemset-based Text Clustering Approach to Cluster Ranked Documents
Country : India
Authors : Snehalata Nandanwar, Geetanjali Kale, Sheetal Sonawane
: 10.9790/0661-16456672     logo

Abstract : In most of the search engines documents are retrieved and ranked on the basis of relevance. They are not necessarily ranked on the basis of similarity between the query and the respective document. The ranked documents are in the form of a list. So there is a need to rank the retrieved documents. We implement Language model that is efficient to retrieve the text documents satisfying given query. The ranking of documents is based on the similarity coefficient calculated using language model. To cluster the ranked retrieved documents, we use FITC (Frequent Item set-based text Clustering) algorithm. The algorithm partitions the documents and returns the cluster in each partition. The algorithm identifies clusters with no overlap. The system accepts user request and returns all the relevant documents partitioned in the form of clusters which satisfy the query. The results of applying the algorithm to document retrieval demonstrate that the algorithm identifies non-overlapping clusters and is therefore of widespread use in many of the search engines.

Abstract : There has been an increasing demand for e-learning technologies and especially for digital watermarking. Using the digital watermarking technology in e-learning is increasingly becoming an important part of the strategy for trusting on-line materials and activities, especially the on-line certificate both easy and cheaply in flexible e-learning way. This paper sets out to develop and create a novel approach to digital watermarking for e-learning certificate that can increase the trustworthiness of e-learning systems in institutions all over the world. This approach will enable these institutions to create an on-line certificate and to add a watermark that can be trusted by other institutions. The most important driving force is concern over protecting copyright, such as for video, audio and other works now available in digital form; it might be that the ease with which perfect copies can be made will lead to large-scale illegal copying, which will in turn undermine the creation of new books, films, pictures etc. the main aims of this paper is to introduce high-quality protected on-line certificates using two kinds of digital watermarking (visible digital watermarking and invisible digital watermarking) in e-learning systems. In addition, this study aims to enable institutions to offer e-learning certificate and to embed digital watermarking systematically.

Abstract : Social networking is an essential part of life for people around the world these days. Social networking is a form of social media, used for interactive, educational, informational or entertaining purposes. Even though social media comes in many forms all of them are related to each other. Social networking is also a tool to create and join groups, learn about latest news and events, play games, chat and to share music and video. Some social networks provide facilities to the users' to partition their group of friends based on social community, organization, geographical location, or how well they knows each other. The main challenge in social network is the sharing of data among heterogeneous users. The proposed method provide a systematic mechanism to identify and resolve privacy conflicts for data sharing, and different access control mechanisms.

Abstract : Global spread of Information Technologyincreases security challenges; over intrusion detection system against sophisticated attacks. This has become of paramount importance since single mode intrusion detection systems have a lot of difficulties in protecting Network from sophisticated attackers. However, this paper propose a Multi-Level Based Hybridized Intrusion Detection System whereby the incoming packets will be examinedfor attacks at two layers; both at Network level as Network Intrusion Detection (NID) and further double check those that escape through the initial test at the second level using Bayes' theorem at Host level as Host based Intrusion Detection (HID). This will help to prevent against intrusion, minimize false alarms and maximize the numbers of detected bad events. It handle masses of information (often in real-time) so as to report the abnormal use of networks and computer systems in a real time before it get out of hand.

Abstract : In Delay Tolerant Networks (DTNs) the core challenge is to cope with lack of persistent connectivity and yet be able to deliver messages from source to destination. In particular, routing schemes that leverage relays' memory and mobility area customary solution in order to improve message delivery delay. When large files need to be transferred from source to destination, not all packets may be available at the source prior to the first transmission. This motivates us to study general packet arrivals at the source, derive performance analysis of replication based routing policies and study their optimization under two-hop routing. In particular, we determine the conditions for optimality in terms of probability of successful delivery and mean delay and we devise optimal policies, so-called piecewise-threshold policies. We account for linear block-codes and rateless random linear coding to efficiently generate red undancy, as well as for an energy constraint in the optimization. We numerically assess the higher efficiency of piecewise-threshold policies compared with other policies by developing heuristic optimization of the thresholds for all flavors of coding considered. Keywords: Delay tolerant networks, mobile ad hoc networks, optimal scheduling, rateless codes, network coding.
