For “SightFinder: Enhanced Videophone Service Utilizing Media Processing”.

The purpose of this study is to construct a framework for enhancing the network services of telecommunications operators. To achieve this framework, we propose “SightFinder,” an enhanced videophone service in which media such as video images are processed on the network by multiple pattern recognition engines working in parallel. This service sends alerts to users on local information when they cannot see it (e.g., visually impaired users) and provides explanations to users who have difficulty understanding it (e.g., foreigners).

For “Efficient Concurrent Oblivious Transfer in Super-Polynomial-Simulation Security.”

In this paper, we show a concurrent oblivious transfer protocol in super-polynomial-simulation (SPS) security. Our protocol does not require any setup and does not assume any independence among the inputs. In addition, it is efficient since it does not use any inefficient primitives such as general zero-knowledge proofs for any NP (nondeterministic polynomial time) statements. This is the first concurrent oblivious transfer protocol that achieves both of these properties simultaneously. The security of our protocol is based on the decisional Diffie-Hellman (DDH) assumption.
