Developments in communications and information technology, along with the introduction of new media, have had an enormous impact on almost all aspects of modern life. In law, areas such as law enforcement, national security, intellectual property, privacy, contracts, and tort law are affected. The rapid evolution of cyberspace has left vulnerabilities to fraud, abuse, and crime, as well as a new venue for warfare and espionage. Both statute and case law are moving to catch up to these new developments and address the challenges posed in meeting the security and privacy demands of society. This volume presents not only a background for understanding these critical issues, but various points of view from experts and case materials.
