An Authorization Model for Multi Provider Queries
Summary: Introduces authorization for collaborative multi-provider cloud queries with three data-visibility levels: none, ciphertext, or plaintext. Enforces policies during execution by constraining operator placement and dynamically adjusting visibility, enabling open-cloud sharing without relinquishing data control.
