Schematize Trust Overlays & Management In Mobile Computing

Mobility leads to unplanned interactions between computer systems or mobile devices, as people use devices to access services in varied environments. Before two or more systems ready to interact, they must trust that each will satisfy the security and privacy requirements of the other. In this paper we introduce trust overlays, a systematic approach to build such trust in Mobile computing world. Our solution exploits the increasing availability of trusted computing hardware on commodity systems, including portable computers. We report that key pieces of these solutions are coming into a place, as systems that provide distributed mandatory access control. We also point out that tremendous challenges remain, such as how to set compatible security policies across administrative domains. ... Read more

Distributed Remote Architectures Neural Base Mining

An emerging trend in the Signal and Image Processing (SIP) community is the appearance of middleware and middleware standards that can be readily exploited for distributed computing applications by the SIP community. High performance computing and High Performance Embedded Computing (HPEC) applications will benefit significantly from highly efficient & portable computational middleware for signal & image processing. Open middleware standards such as VSIPL, MPI, CORBA, encoding and SOAP –based messaging protocols. More specifically, we will be focused on the appropriate use of such technologies for implementing new SIP applications, or extending legacy applications through the use of these technologies. The three middleware standards we have selected all have certain commonalities. All are based around the concept of a client application using the services available on a remote machine, or server. A remote executable object that implements one or more exposed interfaces provides these services. The object’s interface represents a contract between the client and the server. This interface is written as a Java interface for Java RMI, in IDL for CORBA, and in WSDL for web services. In the latter two cases, the more generic descriptions can be translated intospecific language imp lementations, ... Read more

Cyber Crime And Its Implications

The growing danger from crimes committed against computers, or against information on computers, is beginning to claim attention in national capitals. In most countries around the world, however, existing laws are likely to be unenforceable against such crimes. This lack of legal protection means that businesses and governments must rely solely on technical measures to protect themselves from those who would steal or destroy valuable information. Crime is a social and economic phenomenon and is as old as the human society. As, Life is about a mix of good and evil, so is the Internet. For all the good it does to us, cyberspace has its dark sides too The idea of Cyber crime is not new, yet there is significant confusion amongst academics, computer security experts and users as to the extent of real Cyber crimes. In this paper, we explore the breadth of computer-based crime, providing a definition of the emerging terms “Cyber crimes”. In this paper we will try discuss almost every aspect of cyber crime, like meaning then we divide Cyber crime into three distinct categories: Type I Cyber crimes against persons. Type II Cyber crimes against property. Type III Cyber crimes against government. We are describing its classification and explain the Law of cyber crime. And explain the REASONS of cyber crime and who the cyber criminal is and how to prevent from this crime then we use some case studies to illustrate the role different types of Cyber crime, and offer some observations on the role of cognition in the process of Cyber crime. Finally we provide several suggestions for future work in the area of Cyber Crime. ... Read more

Model Driven Architecture (MDA)

The Model Driven Architecture (MDA) separates the system business aspects from the system implementation aspects on a specific technology platform. MDA proposes a software development process in which the key notions are models and model transformation, where the input models are platform independent and the output models are platform specific and can be transformed into a format that is executable. The principles of MDA for the task of study program development are applied using two hemispheres model driven (2HMD) approach, which assumes modeling and use of procedural and conceptual knowledge and may be applied in the context of modeling the knowledge about the domain. From the point of view of 2HMD approach each course of the study program may be considered as a knowledge provider, which satisfies particular knowledge requirements. The particular “Specific” knowledge requirements are derived from the knowledge model that consists of functional and conceptual “hemispheres”, which reflect knowledge derived from original academic or industrial requirements or standards. ...
