Secure Multiparty Computations on Bitcoin
In this work, we propose to use Bitcoin to design fully decentralized protocols that are secure even if no trusted third party is available.

A Differential Approach to Undefined Behavior Detection
This paper studies undefined behavior arising in systems programming languages such as C/C++. We introduce a new static checker called STACK that precisely identifies...

What Makes Paris Look Like Paris?
Given a large repository of geo-tagged imagery, we seek to automatically find visual elements, for example windows, balconies, and street signs, that are most distinctive...
