Digital health technologies have changed the healthcare sector landscape and thus generated new opportunities for collecting, storing accessing electronic personal information (ePHI). However, this has also caused ePHI to be exposed a variety of security threats, attacks vulnerabilities. This qualitative study explored in public hospital South Africa. Data were collected through semi-structured...

Online security advice aims to persuade users to behave securely, but appears to have limited effects at changing behaviour. We propose security advice targeted at end-users should employ visual rhetoric to form an effective, memorable, and persuasive method of communication. We present the design and evaluation of infographics and an online interactive comic developed to persuade users to upda...

Community detection is a challenging optimization problem that consists of searching for communities that belong to a network under the assumption that the nodes of the same community share properties that enable the detection of new characteristics or functional relationships in the network. Although there are many algorithms developed for community detection, most of them are unsuitable when ...

With increased global interconnectivity, reliance on e-commerce, network services, and Internet communication, computer security has become a necessity. Organizations must protect their systems from intrusion and computer-virus attacks. Such protection must detect anomalous patterns by exploiting known signatures while monitoring normal computer programs and network usage for abnormalities. Cur...

This paper presents a new multi-agent system architecture for the RoboCup simulation league. It includes a behavior-based two-layer dynamic agent architecture, a behavior-based decision algorithm, and a role-based dynamic multi-agent cooperation model. A self-confidence function is proposed for the first time and is used to balance decisions and multi-agent cooperation. This architecture has be...

Cyber security threats are still big concerns of the cyber world. Even though many defense techniques have been proposed and used so far, the antivirus (AV) software is very widely used and recommended for the end-usersPC community. Most effective AV products are commercial and thus competitive and it is not obvious for security researchers or system developers how exactly the AV works or how i...

695 Abstract— Smartphone has formed a new market and introduced a new environment. They have an operating system like PCs, enabling free installation and removal of application programs. As the number of Smartphone users is increasing, more personal information is also exposed to malicious codes. There are problem of modification and deletion of files, battery consumption, and information leaka...

Malicious PDF files have been used to harm computer security during the past two-three years, and modern antivirus are proving to be not completely effective against this kind of threat. In this paper an innovative technique, which combines a feature extractor module strongly related to the structure of PDF files and an effective classifier, is presented. This system has proven to be more effec...

With the rapid growth of the Internet and the ever-increasing security problems associated with its popularity, the need for protection against unwanted intruders has become imperative. Antivirus software, intrusion detection systems, spyware detectors, and mal-ware detectors are some of the protection mechanisms available to users today. The diversity of these manifold systems suggests the nee...
