A verifier acting on behalf of a data owner of the data stream may interact with a prover acting on behalf of the data service provider. The verifier may calculate a first root hash value of a binary tree during single-pass processing of the original data stream with limited computational effort. A second root hash value may be calculated using the proof protocol between the verifier and the prover. The prover is requested to provide certain queried values before receiving random numbers used to generate subsequent responses dependent on the provided values. The proof protocol may be used to validate the data processing performed by the data service provider."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interactive proof to validate outsourced data stream processing","description":"A method for validating outsourced processing of a data stream arriving at a streaming data warehouse of a data service provider includes a proof protocol.
