pCloud (Project status: Completed)

In the pCloud project we investigated mathematical and algorithmic foundations  for Reliable and Privacy Preserved Data Storage & Sharing in decentralized environments.

The pCloud project was led by professor Anwitaman Datta, and it was funded for three years and a half under the A*Star Science and Engineering Research Council (SERC)'s Thematic Strategic Research Programme (TSRP) on "Data Value Chain as a Service".
