Computing Arbitrary Functions of Encrypted Data
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…

Technical Perspective: Seeing the Trees, the Forest, and Much More
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…

Using the Forest to See the Trees: Exploiting Context For Visual Object Detection and Localization
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…

Technical Perspective: A First Glimpse of Cryptography's Holy Grail
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…
