Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ..............etc

Water Conservation
Water Scarcity
 Water shortage is used to describe an absolute shortage where levels of available water do not meet certain defined minimum requirements. The actual quantity that determines a per capita minimum may differ from place to place.
 Water scarcity is a more relative concept describing the relationship between demand for water and its availability.
 Water stress is the symptomatic consequence of scarcity which may manifest itself as inc..............etc
