Abstract: Digital watermarking is a promising technology to embed information as unperceivable signals in digital contents. A copyright protection method for digital image with convolutional coding is proposed in this paper. In this method, the watermark logo is coded with convolutional encoder and fused with noise bits to improve the robustness to malicious attacks including JPEG, noise and geometric attacks such as, cropping and rotation. During extraction, the watermark bits are decoded by Viterbi algotithm decoder, and the extraction procedure needs neither the original image nor the watermark logo. Simulation results show that the proposed method based on the convolutional coding can effectively resist the common malicious attacks, the embedding and extraction performances are quite improve compared to the method based on the direct coding.

Abstract: The IEEE 802.16e standard (i.e., mobile WiMAX) has been proposed to provide the connectivity in wireless networksfor mobile users (including users at a vehicular speed). It is shownin our analysis that the probability of a successful handoverdecreases significantly when the user moves at a higher speed. In this paper we have compared three techniques Forward Error Correction (FEC) with retransmission to offer extra protection for handover signaling messages to enhance the probability of a successful handover, especially at a higher velocity, without using a save point between source and destination and using a save point between the source and destination. Comparison between their line graphs is also given in this paper.

Abstract: Wikis are web-based software platforms that allow users to collaboratively create and edit web page content, through a Web browser. The ease-of-use and open philosophy of wikis have made them a simple and quick method for collaborative knowledge management. As wikis mostly contain natural language, the integration of wiki systems with automated Natural Language Processing (NLP) techniques can be considered to support users in information analysis and content development. The presence of the Dravidian language, Malayalam, is comparatively low in popular wikis like Wikipedia. As a solution to this problem, this paper considers the idea of integration of a Hybrid Machine Translator service, a combination of Statistical Machine Translator (SMT) and Translation Memory(TM), with wiki system for automated content generation in Malayalam. A system architecture providing this integration is presented. The whole process is supposed to speed up the content creation in wikis and bridging the language barrier which restricts knowledge dissemination in the web.

Abstract: Clustering of data has been of intense need for any organization in the past and various researchers in the field of data mining have been continuously working to find efficient and accurate tools and algorithms for the same. From the proliferation of internet and network applications is pressing the same need more deeply and it is becoming more and more necessary for providing such algorithms by the researchers of data mining. Researchers have been working continuously and finding incremental clustering mechanism to be best suitable for online data. Clustering of very large document databases is useful for both searching and browsing. The Periodic updating of clusters is required due to the dynamic nature of databases. For this purpose incremental clustering is a profitable approach. Incremental clustering algorithm clusters data in dynamic form. It requires initial clusters to be decided in advance i.e. they must be pre exist and fixed. This work proposed a dynamic and novice approach of incremental clustering algorithm for creating efficient clusters and rearrangement of the clusters on the basis of characteristics of the data. Also an approach of retrieval and searching of some specific data from the fixed clusters using a new frequency check method will be compared with the proposed work.

Abstract:Cloud computing is an internet based model which allows the user all the "services on demand". The services provided by cloud are infrastructure, software and platform. Cloud Computing has great potential of providing robust computational power to the society at reduced cost. Despite the tremendous benefits, security is the primary obstacle that prevents the wide adoption of this promising computing model, especially for customers when their confidential data are consumed and produced during the computation. Wang proposed enabling public audit ability and data dynamics for storage security in cloud computing which provides data integrity and dynamic operation but cannot assure confidentiality. Here in this scheme we are providing a new method which provide confidentiality and also manage the storage space in cloud server. In this we are providing confidentiality by using cryptographic algorithm and storage space is managed by using complete binary tree by arranging all the files by their size and checking the integrity using TPA(third party auditor). Thus providing integrity, memory management as well as confidentiality in cloud computing. Keywords – cloud computing, data integrity, data storage, public audit ability

Abstract: An Ethiopian Cloud database management system is a distributed database that delivers computing as a service instead of a product. It is the sharing of resources, software, and information between multiple devices over a network which is mostly the internet. It is expected that this number will grow significantly in the future. As a result, there is a growing interest in outsourcing database management tasks to third parties that can provide these tasks for much lower cost due to the economy of scale just like putting it into the cloud. In this paper, we discuss the recent trend in database management system and the possibilities of making it as one of the services offered in the cloud. We also Recently the cloud computing paradigm has been receiving significant excitement and attention in the media and blogosphere. To some, cloud computing seems to be little more than a marketing umbrella, encompassing topics such as distributed computing, grid computing, utility computing, and software as- a-service, that have already received significant research focus and commercial implementation. Nonetheless, there exist an increasing number of large companies that are offering cloud computing infrastructure products and services that do not entirely resemble the visions of these individual component topics.

Abstract: One of the major image processing techniques that is widely used in medical, automotive, consumer and military applications is image compression. Discrete wavelet transforms is the most popular transformation technique adopted for image compression. Complexity of DWT is always high due to large number of arithmetic operations. In this work a modified Distributive Arithmetic based DWT architecture is proposed and is implemented on FPGA. The modified approach consumes area of 6% on Spartan-III pro FPGA and operates at 134 MHz. The modified DA-DWT architecture has a latency of 44 clock cycles and a throughput of 4 clock cycles. This design is twice faster than the reference design and is thus suitable for applications that require high speed image processing algorithms.

Abstract: Data mining refers to the process of analyzing the data from different perspectives and summarizing it into useful information that is mostly used by the different users for analyzing the data as well as for preparing data sets. A data set is collection of data that is present in the tabular form. Preparing data set involves complex SQL queries, joining tables and aggregate functions. Traditional RDBMS manages the tables with vertical format and returns one number per row. It means that it returns a single value output which is not suitable for preparing a data set. This paper mainly focused on k means clustering algorithm which is used to partition data sets after horizontal aggregations and a small description about the horizontal aggregation methods which returns set of numbers instead of one number per row. This paper consists of three methods that is SPJ, CASE and PIVOT methods in order to evaluate horizontal aggregations. Horizontal aggregations results in large volumes of data sets which are then partitioned into homogeneous clusters is important in the system. This can be performed by k means clustering algorithm.

Keywords: Aggregations, SQL, pivoting and K-means clustering.

Abstract: This paper proposes a novel cryptographic technique that exploits the advantages of two important techniques – steganography and chaotic image encryption. Steganography is the technique of hiding the message within a cover media. Once the message is embedded within the cover image, it is encrypted using triple-key chaotic image encryption. So altogether this method provides a four-layer security to the original message. Various analyses were done and the results of the experiments are very encouraging and in future, this method can be extended to support media other than images.

Abstract: Wireless sensor networks are the networks with wireless sensors disseminated in a region which sense various types of information and then transmit this information to the other nodes or to the final destination. These nodes sense the changes in the physical parameters similar to – temperature, pressure, etc. The data sensed by these nodes are then approved to the Base Station (BS) for estimation. Wireless sensor networks are used for the variety of purposes like military surveillances, habitat monitoring, forest fire detections, landslide detections. This paper presents the new clustering algorithm by modifying SEP (Stable Election Protocol) for heterogeneous wireless sensor network, called EE-SEP. Energy Efficient -SEP protocol is used to increase the number of alive nodes and thereby increasing the energy efficiency, stability period and network lifetime and balancing the energy consumption. Simulation results show that proposed Energy Efficient SEP algorithm performs better as compared to SEP.

Abstract: Cellular text messaging services are increasingly being relied upon to disseminate critical information during emergencies. Accordingly, a wide range of organizations including colleges and universities now partner with third-party providers that promise to improve physical security by rapidly delivering such messages. The Most of the people are stressed out and overstrained after accidents even if no one is hurt. Consequently, they may face some difficulty in reporting the accident to the police and civil defense, or they may provide them with inaccurate information about the location of the accident. Hence it will take the police and civil defense more time to reach the accident location in the appropriate time to rescue people. Our proposed system The message is sent by the affected person is by a software installed in mobile which doesn't require the user not even to type the message. Then the message will be received by the service center using GSM modem. Using the mobile number and tower location they identify accident location using latitude and longitude in Smart Phones. Then they inform the type of the accident and appropriate location to the nearby service (police & fire). This will reduce the time required for the police and the emergency personnel to reach the accident location.

Abstract: Traffic safety problems are most significant issues all around the world, but out of the ordinary for developing countries, as 90% occurrences happened in these regions. Karachi is the capital of Sindh province and it was the capital of Pakistan during 1947-59 before being replaced by Islamabad. So Karachi considered as vital city of Pakistan due to geo graphic location and different attributes such as population, economy, road networks, sea port and industries to give the impression of being all state of affairs including safety threat become considerable issue in Karachi, Pakistan. In this paper, improvement is center of attention all through in presence situation, polices related problem and call attention GIS contribution. There are necessary a lot of things for doing to emphasize better safety but not including substantial tribulations make known to become in control. By using SPSS and Pivot Table (in excel), easy draw attention to complete situation and here Geographic Information System (GIS) appropriately classify areas as a result of first three highest abnormal numbers of causalities

Abstract: The progress of information technology and the wide reach of the Internet are drastically changing all fields of activity in modern days. As a result, a very large number of people would be required to interact more frequently with computer systems. To develop the human–machine interaction more effective in such situations, it is desirable to have systems capable of handling inputs in a variety of forms such as printed/handwritten paper documents. In a multi-lingual country like India, where more than 22 official languages and 12 different scripts are used for these languages. it is an utmost essential & complicated for designing an OCR system and it became more difficult if the document consist of multiple languages so for an automated multilingual environment such document processing systems relying on OCR would clearly need to identify the script type of the document files, so that specific tool of OCR can be selected. In this paper, a script identification approach for Indian scripts is proposed at text-line level. It is a Visual appearance-based script recognition method. The recognition is based upon features extracted using Discrete Cosine Transform (DCT) and Principal Component Analysis (PCA) algorithm and for further extraction we use Modified-KNN. The proposed method is tested on printed document images in 11 major Indian languages, 95% recognition accuracy is obtained.
