Abstract: A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is regarded as the most reliable and accurate biometric identification system available. In this paper, we describe the novel techniques that are developed to create an Iris Recognition System, A recent survey of iris biometric research from its inception till now lists approximately 29 publications. This new survey is intended to update the previous one, and covers iris biometrics research over the period of roughly 2008 to 2015. Research in iris biometrics has expanded so much that, although covering only these years and intentionally being selective about coverage, this new survey lists a larger number of references.

Abstract: Information system plays a key role for survival and growth of any organisation. To maintain effective and efficient information system is not an easy task for IT Professionals. The basic task of information security is to support the mission of the organization and maintain its existence.
All organizations are exposed to unknown risk which harms the organization. There are several risk to which the Information System is exposed, like fire, virus, hackers etc. These risks should be properly identified and manage   in order to support the organization. We can say risk management is the process of identifying risk, assessing risk, and taking steps to reduce risk to an acceptable level. Managing risk is difficult due to changing technologies, limited resources, threats and vulnerabilities .Due to all these problems it is very difficult to completely mitigating all risks. Therefore, to maintain good information system is challenge for IT Professionals. So, they must have appropriate cost effective techniques to assist them in mitigating risks to a reasonable level. It is needed to manage this risk to maintain confidentiality, integrity or availability of information system.

Abstract: With respect to Multiple Attribute Group Decision Making (MAGDM) problems in which the attribute weights and attribute values take the form of the generalized interval-valued trapezoidal fuzzy numbers, a study is made on a new group decision making analysis called the VIKOR (VIšekriterijumsko KOmpromisno Rangiranje) method. An extended VIKOR method is presented to solve the MAGDM problems in which the attribute weights and values are given with the form of Generalized Interval Valued Trapezoidal Fuzzy Number (GIVTFN). An example is given to show the effectiveness of this method and decision making steps where three different distance functions are used to rank the alternatives.

Abstract: In this work scientific and simple calculation method for manufacturer’s decision-makers to choose the most ideal supplier has been provided. This paper deals with the supplier selection problem based on TOPSIS algorithm (Technique for Order Preference by Similarity to Ideal Solution) with the application of entropy method which is a multiple criteria decision making approach and a Decision Making Support System (DMSS) technique. The TOPSIS algorithm deals with the conflicts between indicators based on certain way to sort the scheme and choose the best scheme. A numerical example is proposed to illustrate the effectiveness of this algorithm. However, Sensitivity Analysis for the weighting vectors is performed to make the result of evaluations more objective and accurate.

Abstract: In modern days money withdrawal via ATM (Automated Teller Machine) becoming a main part of our life. This paper provides the brief description of ATM system. It also explains the issues of ATM system. The security requirements of the ATM system are discussed. The problem of misusing the information related to the customer in ATM system is addressed.

Abstract: Search engine is used to retrieve data from the web in response to user’s queries. Web mining is a technique of data mining, which is used to discover data from the web documents. With the help of Web mining, the user obtains the required information accurately. Web mining is categorized into three types: web content mining, web structure mining and web usage mining. In this paper, difference of three categories of web mining and comparison of web mining and data mining is also presented. Data mining helps to extract data from database, whereas data is extracted from web in web mining.

Abstract: The development of wireless communication is increasing day by day due to the advancement of cellular and broadband technologies. Everyone around the world likes to have best services through best network [Khattab, Omar] [10]. Therefore, the aim of NGWNs is to provide a good quality of services between various access networks. To access different networks, there must be a decision algorithm to decide which is the best network for a user for a specific application. This paper presents an Overview of handoff types, handoff process, the criteria involved in VHD, parameters, Existing work on the vertical handoff with comparison tables, Analysis and Various research issues.

Abstract: The use of the network communication has imposed serious threats to the security of assets over the network. Network security is getting more prone to active and passive attacks which may result in serious consequences to data integrity, confidentiality and availability. Various cryptographic techniques have been proposed in the past few years to combat with the concerned problem by ensuring quality but in order to have a fully secured network; a framework of new cryptosystem was needed. This paper discusses certain cryptographic techniques which have shown far better improvement in the network security with enhanced quality assurance. The scope of this research paper is to cover the security pitfalls in the current systems and their possible solutions based on the new cryptosystems. The development of new cryptosystem framework has paved a new way to the widespread network communications with enhanced quality in network security.

Abstract: Due to overwhelming development of Consumer Centric Cloud applications, the cloud databases also are facing the challenges.  The most important among these challenges include on fly scalability. When an application is sassified, data from ‘n’ entities start residing into the cloud database.  The underlying cloud database should be in a position to accommodate the data from ‘n’ entities.  Here comes the need for scalability and security. This paper mainly focuses on addressing these two issues.  As it is evident that cloud computing has evolved as one of the most powerful and important paradigm for internet or web based applications.   Scalability, dynamic growth, metering and economics of scale from large operators are the major causes for the growth of the cloud infrastructure.  Most of the web based or cloud applications are data driven. The underlying database forms a critical component in the cloud deployment schema. In this paper a new architecture is proposed. This architecture is an extension to the architecture proposed in the paper “Mechanism for Mounting Multiple Databases Over a Universally Shared Instance”. This paper proposes a new Architecture in which database trees are grouped as database tree groups. The remainder of this paper is devoted in developing the proposed architecture for cloud databases.
