            A Wireless Sensor Network (WSN) consists of base stations and a number of wireless sensors (nodes). It is a group of specialized transducers with a communications infrastructure that uses radio to monitor and record physical or environmental conditions. Critical issues for transferring the data securely in cluster based wireless sensor networks. A convenient way to increase the work of wireless sensor networks is clustering. The clustering technique is used in both dynamic and peoridic.There are two protocols used in secure and efficient data transmission (SET) for cluster based wireless sensor networks. They are SET- IBS and SET-IBOOS, by means Identity Based Digital Signature and Identity Based Online/Offline Digital Signature. In SET- IBS security relies on the hardness of the Diffie-Hellman problem in the pairing area. In SET-IBOOS lessen the computational hanging for secure the protocol, which is critical for wireless sensor networks. It is depends on the stability of discrete logarithm problem. The two protocols SET-IBS and SET-IBOOS used for system requirements and analysis across various attacks. The two protocols give the improved performance than existing protocols used in cluster based wireless sensor networks

            Data hiding and extraction schemes are increasing in today’s communication world due to rapid increment of data tracking and tampering attacks. So we need an efficient and robust data hiding schemes to protect from these attacks. In this project the blindly extraction technique is considered. Blindly extraction means the original host and the embedding. Cognitive radio technologies are being developed which allow heterogeneous systems to share spectrum access while minimizing interference to improve the overall efficiency of spectrum usage. Interference minimization requires cognitive radio receivers to be able to detect the presence of all other systems competing for spectrum usage, a process often termed "spectrum sensing". This paper focuses on the kernel function of spectrum sensing: blind interference detection from a single, strictly time-limited, received data vector. Recent research has identified shortcomings in the operation of classical blind interference detection techniques such as energy detection and radiometry. Information hiding technique is a new kind of secret communication technology. The majority of today’s information hiding systems uses multimedia objects like audio. Embedding secret messages in digital sound is usually a more difficult process.

            Boiler requires continuous monitoring and inspection at frequent intervals. In the recent times, boiler has under gone long process of modification right from its conventional working principles to automation using technology in the form of DCS, PLC, SCADA (Supervisory Control and Data Acquisition) etc. An automated system helps in improving their system efficiency, plant monitoring, and productivity. The boiler automation is performed using ON-OFF controller in labVIEW. Indicators placed on the panel it displays the status of sensors and actuators used in the automation of the plant. Simulation provides a good understanding and better visual idea about the real-time performance of boiler, investigates complex operations and control through LabVIEW.

                        The railways require substantial investments in order to keep pace with the 8% growth rate of the economy. Recognizing the need for substantial financial capital and techno managerial expertise, the Railways must encourage private sector participation in massive exercise. Also, competition with the Road and Aviation is driving the railways to improve their standards. The Indian Railway should be ready to interact with private Industry and take further steps to attract investment under Public Private Partnership (PPP) through suitable project delivery methods. This study has involved preparation of a series of working papers covering the Traffic survey and the Reconnaissance Engineering and suitable project delivery methods under ppp. These working papers culminated in this report, which is based on a combination of market, technical and economic modules.

SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database through the firewall that shields it. The attack takes advantage of poor input validation in code and website administration. SQL Injection Attacks occur when an attacker is able to insert a series of SQLstatements in to a ‘query’ by manipulating user input data in to a web-based application, attacker can take advantages of web application programming security flaws and pass unexpected malicious SQL statements through a web application for execution by the database. SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of SQL Server for parsing and executionThe two most important advantages of the new approach against existing analogous mechanisms are that, first, prevent form from SQL injection attacks; second, It does not allow the user to access the data directly in database server. TheXPATHis used to prevent the form from SQL injection. XPath expression is simply called as "an XMLPath”. The XPath language is based on a tree representation of the XML document, and provides the ability to navigate around the tree, selecting nodes by a variety of criteria. The most important kind of expression in XPath is a location path.This is used to generate two filtration models Active Guard and Service Detector of application scripts additionally allowing seamless integration with currently-deployed systems.SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution.Injected SQL commands can alter SQL statement and compromise the security of a web application.SQL Injection is one of the many web attack mechanisms used by hackers to steal data from organizations. It is perhaps one of the most common application layer attack techniques used today.
