Today millions of technologically empowered individuals are able to participate freely in international transactions and enterprises, social and economic. These activities are governed by national and local laws designed for simpler times and now challenged by a new technological and market environment as well as by the practicalities and politics of enforcement across national boundaries. Borders in Cyberspace investigates issues arising from national differences in law, public policy, and social and cultural values as these differences are reformulated in the emerging global information infrastructure. The contributions include detailed analyses of some of the most visible issues, including intellectual property, security, privacy, and censorship.
