The purpose of this paper is to explore the important security factors for protecting data in cloud storage from the perspective of security practitioners. The study consist of 43 security variables (or indicator items) from a survey participated by security practitioners in Malaysia. Exploratory factor analysis (EFA) is conducted to understand the clusters of variables (or indicator items) and...

Computer Assisted Surgery seeks data from various sources related to surgical knowledge, which is mostly represented in the form of discrete databases. However, databases serve as data storage mechanism rather than knowledge representation system. As CAS is becoming more common for various types of surgical interventions, there is a need for representation, storage and processing of surgical kn...

Cloud computing has gained great attention from both industry and academia since 2007.With the goal of providingusersmore flexible services in a transparent manner, all services are allocated in a “cloud” that actually is a collection of devices and resources connected through the Internet. One of the core services provided by cloud computing is data storage. This poses new challenges in creati...

quantitative and model-based prediction of security in the architecture design stage facilitates early detection of design faults hence reducing modification costs in subsequent stages of software life cycle. however, an important question arises with respect to the accuracy of input parameters. in practice, security parameters can rarely be estimated accurately due to the lack of sufficient kn...

Digital information is a critical resource, creating a need for distributed storage systems that provide sufficient data availability and security in the face of failures and malicious attacks. However, the requirements for achieving high availability and security with distributed storage systems usually conflict with each other. This paper proposes a novel data dispersal/encryption scheme impr...
