Computer ethics: philosophical enquiry

sented a keynote lecture entitled ' ~A Whole World in One Glance: Individual and Community in the Digital Age." She described the development of the ubiquitous computing environment in which computing devices will be everywhere our workplaces, our clothing, and even in our bodies. Hurley explained that this future development, involving convergence of various technologies, raises important ethical questions about privacy, identity, anonymity, freedom, security and access. Helen Nissenbaum delivered a keynote address entitled "Can Trust Be Secured Online?" In her talk, Nissenbaum evaluated the idea that trust online could be generated via a toolkit of security mechanisms. Drawing on important insights of philosophers, social scientists and social theorists in general, she argued that a highly secured online world would be conducive neither to trust or trust-worthiness.
