Abstract: Private Cloud computing provides attractive & cost efficient Server Based Computing (SBC). The implementation of Thin client computing for private cloud computing will reduce the IT Cost and consumes less power. Most cloud services run in browser based environment so we don't need a fat client to use in the private Cloud environment. Implementing Thin Client Technology along with Private Cloud Computing will help to reduce the IT Operational Cost by 90% by saving power, space and maintenance. It requires only minimal power for cooling the Infrastructure. Thin Client with private Cloud Computing can be referred as purest form of green computing & carbon free computing.

Title : Blacklisting Misbehaving Users for Enhancing Security in Anonymizing Networks
Country : India

Abstract: Anonymizing networks such as Tor allow users to access Internet services privately by using a series of routers to hide the client's IP address from the server. The success of such networks, however, has been limited by users employing this anonymity for abusive purposes such as defacing popular Web sites. Web site administrators routinely rely on IP-address blocking for disabling access to misbehaving users, but blocking IP addresses is not practical if the abuser routes through an anonymizing network. As a result, administrators block all known exit nodes of anonymizing networks, denying anonymous access to misbehaving and behaving users alike. To address this problem, we present Nymble, a system in which servers can "blacklist" misbehaving users, thereby blocking users without compromising their anonymity. Our system is thus agnostic to different servers' definitions of misbehavior—servers can blacklist users for whatever reason, and the privacy of blacklisted users is maintained.

Abstract: In Wireless Sensor network, nodes are interconnected and information is shared among them. In a situation, many attacks are involved to misuse the wireless sensor network. One of the attacks is replica node replication attack, in which the adversary can detain and conciliation of sensor nodes by hacking IP address of node to make replicas of them and then mount a variety of attacks with these replicas. Opponent controls the entire network and misuse the whole network. Our goal is to detect and block the nodes which are captured by attacker. Sequential Probability Ratio Test is a technique which is used to find the capture node by using two approaches. However, this technique is used to detect the capture node only which affects the neighbor node and have a chance to collapse the network. Blocking Technique is needed to block the particular node captured by attacker. In this work, we propose a fast and effective method for improving the detection of node using the Black Roll technique to effectively block the node by creating a blacklist table which contains block node IP address. Protowall is a tool which is used to block the IP address that is on a blacklist table.

Country : India
Authors : S.Amritha, Mr.S.Saravana Kumar

Abstract: A cloud storage system, used to store large number of data in storage server. Cloud system is used to provide large number storage servers, which provide long-term storage service over the Internet. Third party's cloud system does not provide data confidentiality. Constructing centralized storage system for the cloud system makes hackers stole data easily. General encryption schemes protect data confidentiality. In the proposed system a secure distributed storage system is formulated by integrating a threshold proxy re-encryption scheme with a decentralized erasure code. The distributed storage system not only supports secure and robust data storage and retrieval, but also lets a user forward data from one user to another without retrieving the data back. The main technical involvement is that the proxy re-encryption scheme supports encoding operations over encrypted messages as well as forwarding operations over encoded and encrypted messages. The method fully integrates encrypting, encoding, and forwarding. The proposed system is applied for military and hospital applications, then other secret data transmission.

Abstract: Today's globally networked society places great demand on the dissemination and sharing of information. Privacy Preservation is an important issue in the release of data for mining purposes. How to efficiently protect individual privacy in data publishing is especially critical. With releasing of microdata such as social security number disease by some organization should contain privacy in data publishing. Data holders can remove explicit identifiers to gain privacy but other attributes which are in published data can lead to reveal privacy to adversary. So several methods such as K-anonymity, L-diversity, T-closeness, (n,t) closeness, (α,k)-anonymization, p-sensitive k-anonymity and others method come into existence to maintain privacy in data publishing.

Abstract: LEO satellite has an important role in global communication system. They have advantages like low power requirement and lower end-to-end delay, efficient frequency spectrum utilization between satellites and spotbeams over MEO and GEO satellites. So in future they can be used as a replacement of modern terrestrial wireless networks. There are a lot of handover techniques for LEO satellites like seamless handover (SeaHO-LEO), PatHO-LEO. In our previous work, we have suggested a new handover technique for SeaHO-LEO by introducing a Handover Manager (HM) during the handover process and by simulation we have also shown that it a better approach by comparing it with other existing handover techniques as it reduces the handover latency, propagation delay, call blocking probability more than any other technique. In this paper we have evaluated the exact cost of our previous work i.e. Handover Manager based handover Method (HMBHO). Simulation results show that the cost of Handover Manager based handover management method is better than other handover methods.

Keywords: Handover latency, LEO, Mobile Node (MN),Handover Manager (HM).

Title : A New Wavelet Based SVM Classifier for Wild Fire Detection Using Decision Fusion Framework in Video
Country : India
Authors : S.R Raji, Radha Krishnan B.L

Abstract: There has been an increasing interest in the study of video based fire detection algorithms as video based surveillance systems become widely available for indoor and outdoor monitoring applications. Although many video based smoke-detection algorithms have been developed and applied in various experimental or real life applications, but the standard method for evaluating their quality has not yet been proposed. In this framework, it is assumed that the compound algorithm consists of several subalgorithms, each of which yields its own decision as a real number centered around zero, representing the confidence level of that particular subalgorithm. In this project, the wavelet support vector machine (WSVM)-based model is used for Wild fire detection (WFD). Decision values are linearly combined with weights that are updated online according to an active fusion method based on performing entropic projections onto convex sets describing subalgorithms. The new wavelet kernel is proposed to improve the generalization ability of the support vector machine (SVM). More-over, the proposed model utilizes the principle of wavelet analysis to facilitate nonlinear characteristic extraction of the image data. To reduce misclassification due to fog, an efficient fog removal scheme using adaptive normalization method.

Abstract: The paper presents automatic clustering using Harmony Search based clustering algorithm. In this algorithm, the capability of Improved Harmony search is used to automatically evolve the appropriate number of clusters as well as the locations of cluster centers. By incorporating the concept of variable length in each harmony vector, our strategy is able to encode variable number of candidate cluster centers at each iteration. The CH cluster validity index is used as an objective function to validate the clustering result obtained from each harmony memory vector. The proposed approach has been applied onto well-known datasets and experimental results show that the approach is able to find the appropriate number of clusters and locations of cluster centers.

Title : Dominant Color and Texture Approached for Content Based Video Images Retrieval
Country : India

Abstract: Content-based retrieval allows finding information by searching its content rather than its attributes. Content-based search and retrieval of video data becomes a challenging and important problem. Every year video content is growing in volume and there are different techniques available to capture, compress, display, store and transmit video while editing and manipulating video based on their content is still a non-trivial activity. Recent advances in multimedia technologies allow the capture and storage of video data with relatively inexpensive computers. However, without appropriate search techniques all these data are hardly usable. Today research is focused on video retrieval.Moreover, content-based video retrieval system requires first of all segment the video stream into separate shots. Video Shot Afterwards features are extracted for video shots representation. And finally, choose a similarity/distance metric and an algorithm that is efficient enough to retrieve query – related videos results. There are two main issues in this process; the first is how to determine the best way for video segmentation and key frame selection. The second is the features used for video representation. Various features can be extracted for this sake including either low or high level features. A key issue is how to bridge the gap between low and high level features. In this paper we presented approach for content based video retrieval based on Dominant color and texture of a video image. We also talk about video Representation, feature extraction from like texture, dominant color and color histogram from video frame.

Keywords- Video retrieval, dominant color, Gray level co occurrence matrix. Feature extraction, Key frame extraction, Video representation, and Video segmentation. Image Retrieval, color Histogram

Abstract: Different types of data structure and algorithm have been proposed to extract frequent pattern from a given databases. Several tree based structure have been devised to represent the data for efficient frequent pattern discovery. One of the fastest and efficient frequent pattern mining algorithm is CATS algorithm which represent the data and allow mining with a single scan of database. CATS tree can be used with incremental update of the database. Transaction can be added or removed without rebuilding of the whole data structure.

Keywords – Frequent Pattern Mining, Transactional Databases, Minimum Support, Itemsets.

Abstract: The vehicular communication is an important issue to the researchers who are engaged in preventing traffic accidents and traffic jams. The earlier vehicular models had discussed only communication among vehicles through the Road Side Units (RSU). Most of the researchers used IEEE 802.11 for vehicular communication in which the vehicles are moving inside the city [1]. But in this paper the author uses the latest VANET technology 802.11p in the Manhattan mobility model in which the nodes are moving inside the city [2]. Without using the RSUs, each vehicle in the Manhattan mobility network is treated as a router to communicate with the neighboring vehicles. The standard VANET routing protocols are applied to the Manhattan mobility model and their characteristics are compared with the use of NS 2.34 version simulator and their results are presented in this work [3].
