By analyzing threats that exist in executing procedures, a trust model based on structured protection is proposed. We consider that functional components, system actions and message flows between components are three key factors of information systems. Structured protection requirements on components, connections and action parameters are also provided. Four trusted properties of the model are deducted through formal analysis, and trusted system behavior is defined based on these properties. Furthermore, decision theorem of trusted system behavior is proved. The developed prototype system indicates the model is practical. It is a general theory model built on logic deduction and independent on specific environment and the behaviors of the system designed and implemented following the model are trusted.展开更多

Internet-based healthcare is application of information and communication technologies across the whole range of healthcare functions. It covers everything from electronic prescriptions and computerized medical records to the use of new systems and services that cut waiting times and reduces data errors. Development and implementation of web-enabled communication, patient services and other e-health initiatives are increasingly important to maintaining competitive advantage and to compete for market share. More importantly, value added for patients by facilitating access to information and resources is expected to improve quality of services, speed of treatment and potentially to rationalize management of administrative processes. However, introductions of such e-healthcare services into market can be successful on condition that customers will recognize all these advantages and have trust in organizations provide theses e-services. In this paper authors will concentrate on customer trust as key factor determining success of e-healthcare. The purpose of this study will determine character and power of trust placed by customers in e-healthcare, and to identify factors influencing customers trust to e-healthcare. Authors have ventured thesis that customer trust to e-healthcare is high as consequence of even higher customer satisfaction with traditional healthcare services and great customer trust in traditional healthcare institutions.展开更多
