 Abstract

Nowadays, the security and privacy of users data and files in cloud has become a big concern both for users and also for the cloud service providers. There should be proper security should be provided to data which is send to cloud. we introduce a new two-factor authentication (2FA) access control system for web-based cloud computing services. Specifically, in our proposed 2FA access control system, an attribute-based access control mechanism is implemented with the necessity of a password, secret key and a Trustee response. As a user cannot access the system if they do not hold all these, the mechanism can enhance the security of the system, especially in those scenarios where many users share the same computer for web-based cloud services. In addition, attribute-based control in the system also enables the cloud server to restrict the access to those users with the same set of attributes while preserving user privacy, i.e., the cloud server only knows that the user fulfills the required predicate, but has no idea on the exact identity of the user. Finally, we also carry out a simulation to demonstrate the practicability of our proposed 2FA system.

 Abstract

Intentional or unintentional leakage of confidential data is undoubtedly one of the most severe security threats that organizations face in the digital era. The threat now extends to our personal lives: an excess of personal information is available to social networks and smart phone providers and is indirectly transferred to untrustworthy third party and fourth party applications. In this work, we present a generic data lineage framework LIME for data flow across multiple entities that take two characteristic, principal roles (i.e., owner and consumer). We define the exact security guarantees required by such a data lineage mechanism toward identification of a guilty entity, and identify the simplifying non-repudiation and honesty assumptions. We then develop and analyze a novel accountable data transfer protocol between two entities within a malicious environment by building upon oblivious transfer, robust watermarking, and signature primitives. Finally, we perform an experimental evaluation to demonstrate the practicality of our protocol and apply our framework to the important data leakage scenarios of data outsourcing and social networks.

 Abstract

To keep the head high in globalized economy one has to follow the path of growth, which contains various challenges and issues; one has to overpower these challenges and issues to become a success story. Business is one of the oldest professions that mankind possesses, as time passed and with the advent of technology the earth seemed to squeeze, distances started to minimize, the age of globalization had begun. In the last decade, businesses from developing countries have started to buy out businesses of developed countries as their economies are doing better compared to the developed world due to low cost of production. The process of mergers and acquisitions has gained substantial importance in today's corporate world. This process is extensively used for restructuring the business organizations. In India, the concept of mergers and acquisitions was initiated by the government bodies. Some well known financial organizations also took the necessary initiatives to restructure the corporate sector of India by adopting the mergers and acquisitions policies. The Indian economic reform since 1991 has opened up a whole lot of challenges both in the domestic and international spheres. The increased competition in the global market has prompted the Indian companies to go for mergers and acquisitions as an important strategic choice. The trends of mergers and acquisitions in India have changed over the years. The immediate effects of the mergers and acquisitions have also been diverse across the various sectors of the Indian economy. Till recent past, the incidence of Indian entrepreneurs acquiring foreign enterprises was not so common. The situation has undergone a sea change in the last couple of years. Acquisition of foreign companies by the Indian businesses has been the latest trend in the Indian corporate sector. The Indian IT and ITES sectors have already proved their potential in the global market. The other Indian sectors are also following the same trend. The increased participation of the Indian companies in the global corporate sector has further facilitated the merger and acquisition activities in India. The various factors that played their parts in facilitating the mergers and acquisitions in India are favorable government policies, buoyancy in economy, additional liquidity in the corporate sector, and dynamic attitudes of the Indian entrepreneurs are the key factors behind the changing trends of mergers and acquisitions in India. Even though mergers and acquisitions (M&A) have been an important element of corporate strategy all over the globe for several decades, research on M&As has not been able to provide conclusive evidence on whether they enhance efficiency or destroy wealth. There is thus an ongoing global debate on the effects of M&As on firms. This article seeks to explore the trends and progress in M&As India

 Abstract

In wireless sensor networks, the sensor nodes find the route towards the sink to transmit data. Data transmission happens either particularly to the sink node or through the intermediate nodes. As the sensor node has limited energy, it is imperative to create productive routing strategy to drag out network life time. It is highly dynamic network and specific to the application, and additionally it has limited energy, storage, and processing capability. Every sensor network node can be made out of different sensors that are utilized to collect data is exchanged to the client through system and furthermore control some physical procedures. PSO is a populace based methodology for progression. It is a computational knowledge oriented, stochastic, populace based global optimization strategy. The mobile agents can move wherever and at whatever point and they are accountable for social event the recognized data and forward them to the settled network involving Access Point. There are different methodologies for studying the mobility for data collection in WSNs. In this paper, Differential Evolution used for clustering and CH formation. Mobile sink is used for the data collection and increase the network lifetime.

 Abstract

Today wireless technologies simply coexist without any coordination (within one technology as well as among different technologies). This leads to more and more unwanted and uncontrolled interference, and hence inefficient spectrum usage, which is getting more problematic as the density of wireless devices increases. Radio spectrum is the most valuable resource in wireless communication. The cognitive radio and cognitive based networking are transforming the static spectrum allocation based communication systems in to dynamic spectrum allocation. Cognitive radios are intelligent devices with ability to sense environmental conditions and can change its parameters according to the requirements to get the optimized performance at the individual nodes or at network level. This paper covers the basics and origin of software defined radio, cognitive radio, cognitive radio network, cognitive cycle, signalling, Cognitive Radio Sensor Networks and the concept of cross layer design. The performance metrics explain the node and network level performance measurements. This paper also covers the different network paradigms

 Abstract

This paper deals with ultrasound fetal image for finding the abnormalities of fetal in first trimester period of pregnancy. Finding aberration in first trimester period is essential in order to overcome the abnormalities by suitable medical treatments. A way to identify the abnormalities this research work proposes an object-based feature selection and an optimization module. OBF uses Structural information extracted from an object to address the curse of dimensionality. Multi resolution segmentation and object based feature extraction are performed for fetal image and particle swarm optimization is used to evaluate and sharpen the accuracy of the detection methodology. Experimental results depict hybrid object based optimization model produces remarkable results.
