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 …

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
