    Abstract. The recent advances in mobile devices and wireless communication sector transformed Mobile Augmented Reality (MAR) from science ļ¬ction to a reality. Incorporating this MAR technology in health care sector elevates the quality of diagnosis and treatment for the patients. However, due to the highly sensitive nature of the data being circulated in this process, it is also highly vulnerable to the security threats. In the thesis, an architecture is proposed for a MAR health care application based on Multi-access Edge Computing (MEC). This includes key features such as displaying augmented view of patient information on the mobile device, augmenting the X-ray or scan image on top of the patientā€™s actual body parts to assist the doctor, and enabling the doctor to interact with an expert and get real time consultancy. Based on the proposed architecture, all the possible network security threats are analyzed. Furthermore, a secure key management scheme is proposed for registration and authentication phases to establish a secure end-to-end communication between the participating entities in the system. The security features of the proposed scheme are formally veriļ¬ed by using Automated Validation of Internet Security Protocols and Applications (AIVSPA) tool, Moreover, an informal veriļ¬cation is provided to discuss the protection against other possible attacks. It has justiļ¬ed that the proposed scheme is able to provide the required level of security for the system

    An innovative mobile application for construction programme managers

    Construction programme management is a complex and information-intensive environment. The construction programme management team requires access to construction information in real-time and when needed. The current increasing use of mobile devices offers an opportunity to meet this need. The efficient management of construction programmes is one of the major factors for improving stakeholdersā€™ satisfaction. An innovative tool is needed in accessing the right information at the right time, especially when spontaneous and urgent decision-making is needed. To this end, the innovative use of a mobile device in delivering information and services to the management team in real-time and based on their current context offers significant benefits. This paper discusses context-aware computing, the enabling technologies for geolocation and the development of a prototype, mobile, context-aware application for construction programme management. The prototype system developed is based on the findings from an earlier study of user requirements which showed that the ability to provide relevant information and services at an appropriate time and at the most appropriate location has the potential to improve the monitoring and control of construction programmes. The prototype system demonstrates the provision of context-specific information and services to construction programme managers using a mobile device. The benefits and limitations of the proposed approach are discussed and conclusions drawn about the potential impact of enhanced information delivery for the efficiency of the construction programme managers
