Abstract: A number of research papers has been produced about reversible watermarking. Reversible watermarking is one of the important scheme of the watermarking schemes. Some security measures must be there to protect the records from unauthorized user and destruction of information. Basic idea of digital watermarking is to embed the data into the cover media to provide the security to data. The watermarking techniques satisfying these requirements called as Reversible watermarking. Ownership of the original media remains same but the best thing is original media is recovered from the watermarked media. This is the best and main feature of reversible watermarking to extract the original image as it is without any distortion. This feature is applicable in various areas such as medical as well as military images. If there is effect on the cover then it would changes the meaning of this data. The aim of this paper is to represent the purpose of reversible watermarking, some of the techniques related to reversible watermarking.

Abstract: Noise in images is the vital factor which degrades the quality of the images. Reducing noise from the satellite images, medical images etc., is a challenge for the researchers in digital image processing. Several approaches are there for noise reduction. Generally speckle noise is commonly found in Synthetic Aperture Radar (SAR) satellite images and medical images. This research paper put forward some of the filtering techniques for the removal of speckle noise from the satellite images, which enhances the quality of the images. Although many filters are available for speckle reduction, some filters are best suited for SAR images are used for which the statistical parameters are calculated for the output images obtained from all the filters. The statistical measures SNR, PSNR, RMSE and CoC are compared. The output images corresponding to the best statistical values are displayed along with the filters name and corresponding values of the statistical measures.

Abstract:The high costs incurred in multiple supplier/Buyer transaction forms the basis for the introduction of a high-value agent service. This type of agent-based model can lower the cost for both buyers and sellers, including monetary, mental and physical expenditure. Cloud computing is not just about cost. It can provide a platform for a business to achieve its ambitions of having an "inclusive" IT system that covers entire supply chain and its customers, enabling and generating business growth more effectively.

Abstract: In data mining community, sequential pattern mining has been studied extensively. Most studies require the specification of minimum support threshold to mine the sequential patterns. However, it is difficult for users to provide an appropriate threshold in practice. To overcome this, we propose mining top-k closed sequential patterns of length no less than min_l, where k is the number of closed sequential patterns to be mined, and min_l is the minimum length of each pattern. We mine closed patterns since they are solid representations of frequent patterns.

Abstract: Mobile Cloud Computing (MCC) which combines mobile computing and cloud computing, has become one of the industry buzz words and a major discussion thread in the IT world since 2009. Despite increasing usage of mobile computing, exploiting its full potential is difficult due to its inherent problems such as resource scarcity, frequent disconnections, and mobility. MCC integrates the cloud computing into the mobile environment and overcomes obstacles related to the performance (e.g., battery life,storage, and bandwidth), environment (e.g., heterogeneity, scalability, and availability), and security (e.g., reliability and privacy) discussed in mobile computing. As MCC is still at the early stage of development, it is necessary to grasp a thorough understanding of the technology in order to point out the direction of future research. With the latter aim, this paper presents a review on the background and principle of MCC, characteristics, recent research work, and future research trends.

Title : A Survey on Vehicular Ad hoc Networks
Country : India
Authors : Mr. Bhagirath Patel, Ms. Khushbu Shah
: 10.9790/0661-1543442    logo

Abstract: Vehicular Ad hoc Networks (VANETs), a subclass of mobile ad hoc network (MANET), is a promising approach for the intelligent transport system (ITS). VANET allows vehicles to form a self-organized network without the need for a permanent infrastructure. As the VANET has a potential in improving road safety, real time traffic update and other travel comforts, it turns attention of the researcher. Though VANET and MANET shares some common characteristics like self-organized network, dynamic topology, ad hoc nature etc, VANET differs from MANET by challenges, application, architecture, power constraint and mobility patterns, so routing protocols used in MANET are not applicable with VANET. New routing strategy for VANET has been proposed by many researchers in recent year. This paper provides focus on the various aspects of VANET like architecture, characteristic, challenges, glimpse of routing protocols, and simulation models used for VANET.

Abstract: Image inpainting is a technique to fill missing region or reconstruct damage area from an image.It removes an undesirable object from an image in visually plausible way.For filling the part of image, it use information from the neighboring area. In this dissertation work, we present a Examplar based method for filling in the missing information in an image, which takes structure synthesis and texture sysnthesis together. In exemplar based approach it used local information from an image to patch propagation.We have also implement Nonlocal Mean approach for exemplar based image inpainting.In Nonlocal mean approach it find multiple samples of best exemplar patches for patch propagation and weight their contribution according to their similarity to the neighborhood under evaluation. We have further extended this algorithm by considering collaborative filtering method to synthesize and propagate with multiple samples of best exemplar patches. We have to preformed experiment on many images and found that our algorithm successfully inpaint the target region.We have tested the accuracy of our algorithm by finding parameter like PSNR and compared PSNR value for all three different approaches.

Abstract: Web services are application based programming interfaces (API) or web APIs that are accessed through Hypertext Transfer Protocol (HTTP) to execute on a remote system hosting the requested services. A RESTFUL web service is a budding technology, and a light weight approach that do not restrict the client-server communication. The open authorization (OAuth) 2.0 protocol enables the users to grant third-party application access to their web resources without sharing their login credential data. The Authorization Server includes authorization information with the Access Token and signs the Access Token. An access token can be reused until it expires. An authentication filter is used for business services. This paper presents a secure communication at the message level with minimum overhead and provides a fine grained authenticity using the Jersey framework.

Keywords: Open authorization (oauth), Restful web services, HTTP protocols and uniform resource identifier(URI).

Abstract: Steganography is the art and science of hide secret information in some carrier data without leaving any apparent evidence of data alternation. In the past, people use hidden tattoos, invisible ink or punching on papers to convey stenographic data. Now, information is first hide in digital image, text, video and audio. This paper discusses existing BPCS (Bit Plane Complexity Segmentation) steganography techniques and presences of some modification. BPCS technique makes use of the characteristics of the human visible system. BPCS scheme allows for large capacity of embedded secret data and is highly customized. This algorithm offers higher hiding capacity due to that it exploits the variance of complex regions in each bit plane. In contrast, the BPCS algorithm provided a much more effective method for obtaining a 50% capacity since visual attacks did not suffice for detection.

Title : An Efficient Approach for Requirement Traceability Integrated With Software Repository
Country : India
Authors : P.M.G.Jegathambal, N.Balaji
: 10.9790/0661-1546571    logo

Abstract: Traceability links between requirements of a system and its source code are helpful in reducing system conception effort. During software updates and maintenance, the traceability links become invalid since the developers may modify or remove some features of the source code. Hence, to acquire trustable links from a system source code, a supervised link tracing approach is proposed here. In proposed approach, IR techniques are applied on source code and requirements document to generate baseline traceability links. Concurrently, software repositories are also mined to generate validating traceability links i.e. Histrace links which are then called as experts. Now a trust model named as DynWing is used to rank the different types of experts. DynWing dynamically assigns weights to different types of experts in ranking process. The top ranked experts are then fed to the trust model named as Trumo. Trumo validates the baseline links with top ranked experts and finds the trustable links from baseline links set. While validating the links, Trumo is capable of discarding or re-ranking the experts and finds most traceable links. The proposed approach is able to improve the precision and recall values of the traceability links.

Abstract: Memory forensics and data carving methods are usually used during volatile investigation and is nowadays a big area of interest. Volatile memory dump is used for offline analysis of live data. Live analysis of the running system gives the information of which events are going on. Volatile memory analysis can give the sensitive information such as User Ids, Passwords, Hidden Processes, Root kits, Sockets etc. which are not stored on the physical drive. This Paper represents various approaches and tools used to capture and analyse data from computer memory.

Keywords: Memory forensics, RAM, sensitive information.

Abstract: Ethernet is most influential & widely used technology in the world. With the growing demand of low latency & high throughput technologies like InfiniBand and RoCE have evolved with unique features viz. RDMA (Remote Direct Memory Access). RDMA is an effective technology, which is used for reducing system load & improves the performance. InfiniBand is a well known technology, which provides high-bandwidth and low-latency and makes optimal use of in-built features like RDMA. With the rapid evolution of InfiniBand technology and Ethernet lacking the RDMA and zero copy protocol, the Ethernet community has came out with a new enhancements that bridges the gap between InfiniBand and Ethernet. By adding the RDMA and zero copy protocol to the Ethernet a new networking technology is evolved called RDMA over Converged Ethernet (RoCE). RoCE is a standard released by the IBTA standardization body to define RDMA protocol over Ethernet. With the emergence of lossless Ethernet, RoCE uses InfiniBand efficient transport to provide the platform for deploying RDMA technology in mainstream data centres over 10GigE, 40GigE and beyond. RoCE provide all of the InfiniBand benefits transport benefits and well established RDMA ecosystem combined with converged Ethernet. In this paper, we evaluate the heterogeneous Linux cluster, having multi nodes with fast interconnects i.e. gigabit Ethernet & Soft RoCE. This paper presents the heterogeneous Linux cluster configuration & evaluates its performance using Intel's MPI Benchmarks. Our result shows that Soft RoCE is performing better than Ethernet in various performance metrics like bandwidth, latency & throughput.

Title : A comparative analysis on qos multicast routing protocols in MANETs
Country : India
Authors : Mamata Rath
: 10.9790/0661-1548892    logo

Abstract: Simultaneous transmission of data from one sender to multiple receivers is called multicasting. Several widely used applications require multicasting at least at the logical level. Examples include audio video teleconferencing, real time video streaming and the maintenance of distributed databases. In many cases it is advantageous to implement multicasting at the level of the routing algorithm (other approaches would be one-to-all unicast or the implementation of multicasting at the application layer). In this paper we are presenting a comparative analysis on various multicast routing protocols in adhoc networks.
