Electronic health record (EHR) system facilitates integrating patients' medical information and improves service productivity. However, user access to patient data in a privacy-preserving manner is still challenging problem. Many studies concerned with security and privacy in EHR systems. Rezaeibagha and Mu [1] have proposed a hybrid architecture for privacy-preserving accessing patient records...

Service Reliability is an important consideration for new service deployment. Traditional system-oriented measures are no longer adequate to describe the reliability perceived by the user. In this paper we propose a general service reliability analysis approach based on user behavior, and derive formulas to compute service reliability from the user model and service models. The derived user-per...

Existing service discovery protocols are designed to take less consideration of different service qualities. Consequently, after the client discovers the services using specific service type information, selecting the best qualifying one among identical services is left to the user or application developers. This paper proposes a quality of service discovery framework which enables a client to ...

Mobile users need access to information sources. However, for a number of reasons, the traditional representation of query results is not useful in mobile environments. There is also a pressing question of using network services to provide mobile users with required information. The potential to dynamically bind services at run time is one of the big advantages of service oriented computing. Ho...

Cloud computing technology has gained enormous attention due to its promising capabilities such as virtualization, elasticity and the pay-per-use paradigm. Theoretically, cloud computing can offer Everything as a Service (XaaS). Selecting suitable cloud services matching the Quality-of-Service (QoS) requirements of the user is one of the prominent problems in the literature. A considerable numb...
