We all know how to protect our private or most valuable data from unauthorized access: encrypt it. Still, the use of encryption to protect valuable or sensitive data can be
Suppose that you want to delegate the ability to process your data, without giving away access to it. This separation is possible: we describe a "fully homomorphic" encryption scheme that keeps data private, but that allows a
Bristling with cameras, microphones, and other sensors, today's portable phones are nevertheless essentially deaf and blind. How shall we go about building machines that can
Recognizing objects in images is an active area of research in computer vision. However, most of the algorithms for detecting objects perform an exhaustive search across all locations and scales in the image comparing local image

Last month (February 2010, p. 120) we posted a trio of brainteasers, including one as yet unsolved, concerning the breaking of a bar of chocolate.
Future Tense, one of the revolving features on this page, presents stories and essays from the intersection of computational science and technological speculation, their boundaries limited only by our ability to imagine what

There is renewed interest in emergency planning in both the private and public sectors. As managers realize the size of potential exposure to unmanaged risk, insuring "business continuity" is becoming a key task within all industrial
As many as 400 people may have access to one's personal medical information throughout the typical care process. Patients (consumers) feel that it is critical that their medical information is held in confidence, otherwise they
Is stickiness the Holy Grail for e-tailing? The conventional wisdom suggests that stickiness is crucial and can contribute to e-tailers' bottom lines considerably. However, the direct economic impacts of stickiness have not been
A recent industry survey observed that only 34% of IT projects were considered successful. Of the several potential factors contributing to this hard-to-achieve success, user involvement was noted as the most important one.
The established philosophy within the software development industry is that an organization implementing a program to improve software quality can expect to recoup the cost of the implementation many times over. While organizations
Perhaps the business case for adopting open source software is an easy sell. Less obvious than the cost savings but equally important are the barriers ("hidden costs") of adopting open source software.
A paradox is becoming obvious to both information systems (IS) academics and executives: U.S. demand for IS graduates is increasing, but graduation numbers from university IS programs are flat or in decline, and many CIOs report
Agent-based systems, or multi-agent systems in general, are a contemporary paradigm for software development.
