Regression on distributed databases via secure multi-party computation
Alan F. Karr, Xiaodong Sheldon Lin, Ashish P. Sanil, Jerome P. Reiter · 2004
We present a method for performing linear regression on the union of distributed databases that does not entail constructing an integrated database, and therefore preserves confidentiality of the individual databases. The method can be used by statistical agencies to share information from their individual databases, or to make such information available to others.
