The security-and-privacy world is changing rapidly. We've long thought about security and privacy as two equivalent goals, picturing a world in which both were equally achievable and could exist simultaneously. However, we've learned that security and privacy are sometimes mutually exclusive. For example, after the 2015 terrorist attack in San Bernardino, California, the US Federal Bureau of Investigation clashed with Apple over access to the shooter's iPhone.

Multimedia semantics is more than developing ontologies to describe the nature of multimedia content. It’s the key research area for interoperable, intelligent access to and management of multimedia materials. There are many metadata standards. More than 10 organizations vie for leadership in content description, including the Dublin Core Metadata Initiative,…

With the wide adoption of Web and mobile technologies and with the virtualization of many facets of everyday life as a backdrop, social computing takes a computational approach to the study and modeling of social interactions and communications. It also encompasses the development of information and communications technologies (ICTs) supporting…

System virtualization is a method for executing applications in which the applications are installed in and executed by a software representation of a real computer called a system virtual machine. System VMs, in turn, run on top of a software layer called the hypervisor. System virtualization is the underpinning for a number…

Cloud computing is one of today’s most-discussed technical topics. Despite the relative decline of grid computing and unfulfilled promises of utility computing, cloud computing appears to be catching on in both industry and academia. Compared to its predecessors, cloud computing seems to be better positioned in terms of economic viability,…

The boundaries between the real and virtual worlds are breaking down: computer-generated (CG) characters and scenes in movies engage and convince us, and our kids are as comfortable interacting with graphical environments and characters as they are with their own real-world friends and families. This trend is not only true…

Computer science practitioners deal with ethical challenges daily. How they deal with these challenges has ramifications that go beyond personal responsibility; often, the health, safety, and welfare of the public are at stake. This month, Computing Now covers professional ethics, which concerns what computing professionals should and shouldn’t do in…

The Internet has evolved from a dial-up command line childhood into a broadband, visually rich adolescence. However, in many ways it’s still handicapped by its laissez-faire heritage. Video—the most powerful visual multimedia format—requires significantly higher bandwidth, quality of service, reliability, scalability, and security than Internet’s best-effort legacy might be able…

In recent years, trust in computing has been receiving increased attention. With the emphasis on loosely coupled and decentralized systems and the advent of service orientation, trust management has moved beyond the domains of security, multiagent systems, and e-commerce to become a key concern across all aspects of computing. However,…

Serious games use video game technologies to simulate realistic situations, providing valuable experience that can support discovery and exploration while saving money and lives. Serious games have been used for many purposes, including flight and vehicle simulation, scientific simulation and visualization, industrial and military training, medical and health training, education,…
