Offering strong data protection to cloud users while enabling rich applications is a challenging task. The cryptographic security solutions existing and applied over internet cannot directly be applied to the cloud environment. This paper presents a couple of security solutions. Several homogaphic and disk encryption methods and their limitations are discussed. The efforts to combine the benefits of both the techniques give rise to further more possibilities. The author hopes that all the possibilities are researched and a single platform layer security suit will be made for cloud data protection.

Due to the exponential growth of the Internet, search engines have the complex task of sorting through billions of pages and displaying only the relevant pages for the submitted search data. Google has become an essential link to search the information online. Due to this reason, Search Engine Optimizers should actively learn the techniques that drive visitors to their site. Searching online has become a part of everyday lives of most people. Whether to look for information related to their daily lives, most people have made search engines part of their daily routine. Because of this reason, search engines occupy �a prominent position in the online world�; they have made it easier for the people to find the information among the millions of web pages on the Internet. Due to the large number of websites, search engines have the complex task of sorting through the millions of pages and displaying only the most relevant pages. This Research Paper provides the analysis of Search Engine Optimization techniques that can help to improve the ranking of a website or to get more number of viewers or to increase visibility of a website.

In this paper data mining technique available which useful in mining the pattern of text document. However efficiently Research of new pattern which is useful and update the discover patterns is still an open research issue, especially in text mining field. Existing text mining methods have term based approaches and they have problems of polysemy and synonymy. To reduce these problems people develop the phrase (pattern) based approach. The phrase based approach is better than the term based approach but many experiments are not done in phrase based approach. In this we present the new innovative and effective pattern discovery method which has a process of pattern deploying and pattern evolving, which improve the efficiency and updating new pattern for finding appropriate and interacting information.

To design a data flip-flop consistent with the three-phase dual-rail pre-charge logic (TDPL) family. TDPL is a differential power analysis (DPA) resistant dual-rail logic style whose power consumption is insensitive to unbalanced load conditions, based on a three phase operation where, in order to obtain a constant energy consumption and also reduce the power dissipation replacing the discharge and evaluation phase by pull up and pull down networks using Reverse Logic. A part of an encryption algorithm is used as case a study to prove the effectiveness of the proposed circuit. Simulation results in a 65 nm CMOS process show an improvement in the energy consumption and power consumption.

As the demand for wireless increases there is rapid development of various wireless technologies. The users want to use wireless communication services anytime and anywhere. Wireless Sensor Networks (WSNs) are expected to play an important role in future to provide reliable data transmission. But the traditional WSN works in unlicensed band and suffer from uncontrolled interferences from the networks sharing the same spectrum. As it resides in high Bit Error Rate there is increased delay in data transfer which results in less throughput. In this paper the WSN using cognitive concept is studied for reliable data transmission.

This paper focuses on control and automation of intelligent road symbol detection system for vehicles in normal environment conditions. The objective is to look for matching information or some data in the input images that are taken by the overhead mounted camera. The whole setup then filters the noise and other requirements to obtain a steady flow of information for the vehicle to be guided automatically. Here we have used MATLAB for image processing and a microcontroller interfaced with it for actual real time processing and actuation of commands. The functions attributed in the whole setup are direction control mechanism, UART Communication and MATLAB. The results obtained are shown along with neatly explained algorithm and flowchart.

A Mobile Ad hoc Network (MANET) is a collection of wireless devices that can exchange information dynamically. The nodes in the network exchange information using the topology of the network. The ad-hoc network suffers from excessive traffic and maximum control overheads during route discovery. In this paper we have describe the clustering approach in ad-hoc network. The cluster based routing protocol (CBRP) divide the network in to small groups. The cluster head is elected to manage a cluster. Cluster heads in the network are responsible for information exchange. Using clustering approach flooding and overhead problems within the network can be effectively minimized.

One of the main reasons for income loss in enterprises that is usually addressed by providing redundant software and hardware is Service downtime. A way to provide software redundancy is to create a replica of the state of a program in execution to a set of replicas such as, when the primary fails. The place of the formerly running application occurrence is presumed by one of the replicas. A prototype of continuously available replica programs is provided, in case of failure of primary a replica takes over the functionality without any service downtime. Thus, the costly task of starting a new application occurrence on the other machine is avoided. When the mail server get disconnected, design offline email gears service. Or email gears are being developed To encounter the network failure . All email operations can be performed even if the network fails.

The escalate of crime rate around the global manifests the lag in the ongoing methodology in extraction or inspection of information retrieved and stored in cache from divers communication channels of the digital investigation system. The Principle objective for the development of this strategy, is to revamp the existing methodology and develop a crime relates information mining framework for extracting and examine pertinent information from stored data which incorporates emails, chat threads and any text messages to discover the criminal activity and solve the enigma with the help of the certainty concealed within the data. This strategy is achieved by the prominence of the three aspects initiated to the input data of textual evidences such as mails, text messages, chat threads, etc. the three aspects are, the separation of the body and header part of a textual corpuses consisting of all kinds of textual evidences of diverse communication channels and preprocessing of text , which is achieved using regular expressions of PHP script and stemming process respectively, in order to make the mining process of text more reliable for the forensic department of crime investigation. Further the searching technique used in this methodology which is constructed for the most highly effective and efficient retrieval of data. Although the technique followed in this methodology is an ancient technique of separation of body and header in a mail, the main aspect of this methodology is to focus over the efficiency in searching technique built for the purpose of effectiveness. A Clustering algorithm is used in this methodology to improvise the system. This algorithm has mainly three feature, it is the alternative form of the Reverse Factor algorithm, it uses bit-parallelism simulation of the suffix automaton of xR and it is efficiency is high if the pattern length is not longer than the memory-word size of the machine. Using this kind of technique to improvise the existing system would bring about a methodical procedure, which would initiate in a highly efficacious searching system, evidenced by the time complexity, precision and recall value. The preprocessing of text, that is stemming is done for easier understanding and convince of the user to suspect over threads and text document. Integrating all the factors specified would assist in easier reviewing of the text messages.
