Problem statement: It is important to secure the transmission of patient’s EHR in remote health monitoring systems. Security is among the main issues that need to be realized for the adaption of this monitoring technology. The face of healthcare is changing as ubiquitous computing technologies are being incorporated into the existing infrastructure. We specify the requirements, needed security ...

Many enterprises are implementing service-oriented architecture (SOA) using Web services, and are designing those services according to the principles of Model Driven Architecture (MDA). Because the UML used to express MDA lacks model elements for indicating the security needs of business processes, system architects are forced either to ignore security concerns in their models, or to indicate ...

Instead of simply using two-dimensional User × Item features, advanced recommender systems rely on more additional dimensions (e.g. time, location, social network) in order to provide better recommendation services. In the first part of this paper, we will survey a variety of dimension features and show how they are integrated into the recommendation process. When the service providers collect ...

This paper deals with modern cellular phones that operate on Voice over Internet Protocol, their current development, several Information security risks associated with them and various countermeasures that can be undertaken to prevent data theft/misuse. VoIP is vulnerable to well known traditional modes of attack such as Denial of Service (DoS),Man in the middle (MiTM) etc but also introduces ...

A smart city is developed, deployed and maintained with the help of Internet of Things (IoT). The smart cities have become an emerging phenomena with rapid urban growth and boost in the field of information technology. However, the function and operation of a smart city is subject to the pivotal development of security architectures. The contribution made in this paper is twofold. Firstly, it a...

Cyberspace refers to the boundless space known as the Internet. Cyber security is the body of rules put in place for the protection of this cyberspace. The increasing use of e-Learning systems has been documented by numerous studies and shows continuing growth; little attention has been given to the issue of security of e-Learning systems both in research and education. In this paper, we illust...

This paper shows how aspects can be successfully employed in the support of system evolution. The context is a case study on migrating a legacy client-server application to overcome the security problems associated with ‘message tampering’ attacks. The focus is on authorization issues in which aspects are used to add a security mechanism based on digital signatures. The approach provides for fu...
