Abstract:
Embodiments herein provide a method, system, etc. for a sovereign information sharing service. More specifically, a method for secure distributed query processing comprises storing data tables from at least one data provider in at least one first computer comprising a sovereign server. Next, encrypted input and output of the data tables is performed between the server and a second computer. Following this, join operations are computed, comprising determining whether arbitrary join predicates yield matches within the data tables; and encrypted results of the join operations are output. The method minimizes possible information leakage from interaction between the server and the second computer by making observations and inferences from patterns of the outputting of the encrypted results.
