The Intelligence Advanced Research Projects Activity (IARPA) is soliciting proposals for research projects in secure multiparty computation:
Specifically of interest is computing on data belonging to different — potentially mutually distrusting — parties, which are unwilling or unable (e.g., due to laws and regulations) to share this data with each other or with the underlying compute platform. Such computations may include oblivious verification mechanisms to prove the correctness and security of computation without revealing underlying data, sensitive computations, or both.
My guess is that this is to perform analysis using data obtained from different surveillance authorities.
