About Me


Costantinos Costa

Visiting Lecturer

My research focuses on spatio-temporal operators of online anonymous networks and mobile telecom big data analytics. The smartphone revolution has introduced a new era of social networks where users communicate over anonymous messaging platforms to exchange opinions, ideas and even carry out commerce. These platforms enable individuals to establish social interactions between strangers based on a common interest or attribute. We have already developed a novel anonymous crowd messaging architecture, which utilizes the location of each user to connect them instantly to their k Nearest Neighbors (kNN) as they move in space. We collected and analyzed data from the network interactions of thousands of active users that used our award-winning Rayzit crowd messaging service ( Contrary to the very large body of location-based social networks that suffer from bootstrapping issues, our architecture enables a user to always interact with the geographically closest possible users around. We establish this communication using a fast computation of an All kNN query that generates a dynamic global social graph every few seconds.
