Broadcasting Private Messages Securely

Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

Consider a source, Alice, broadcasting private messages to multiple receivers through a broadcast erasure channel; users send back to Alice public feedback that she causally uses to decide the coding strategy for her following transmissions. Recently, the ...

An Alternative Scanning Strategy to Detect Faces

Sébastien Marcel, Venkatesh Bala Subburaman

The sliding window approach is the most widely used technique to detect faces in an image. Usually a classifier is applied on a regular grid and to speed up the scanning, the grid spacing is increased, which increases the number of miss detections. In this ...

Silence-Based Communication

Christina Fragouli

Communication complexity---the minimum amount of communication required---of computing a function of data held by several parties is studied. A communication model where silence is used to convey information is introduced. For this model the worst-case and ...
