We propose that the technology must support principles such as human rights, privacy, safety, and dignity. The voluntary contribution of people as participants in research must undergo the scrutiny of research plans by ethical review boards. Informed consent processes and procedures must be observed in this realm. Ethical issues arising in heterogeneous fields involving technology, end-users, service providers, and formal and informal caregivers pose important challenges. Attempting to maximize the ethical compliance of the results of this ICT （information and communication technology） project, we explore and suggest preventive measures for possible scenarios of misuse of this or related technology. Concluding, the observation of ethical principles throughout the development process can empower users to make informed decisions on the acceptance of ICT systems and services when these reach the market.展开更多

The success of such a program depends primarily on the effective implementation and execution of associated information security policies and controls. These policies and controls depend directly upon the resultant behavior and actions of end-users. Hence, end-users play a critical role in the effective implementation and running of an information security program in any organization. However, end-users are often unable to navigate and comprehend the various policies, controls and associated issues. Support to end-users is therefore a vital element, but is often neglected by present information security management systems. In the service industry, support to customers is established as an important determinant of customer perceived service quality. This paper applies the same philosophy to provide support to end-users, who are the customers of the Information Security Service.展开更多
