US 2021/0240830 A1 · ATTESTATION OF PROCESSING

Abstract

There is provided a data processing apparatus that includes an input policy filter that receives input data and an input provenance that relates to the input data. The filter forwards some or all of the input data and the input provenance according to at least one input policy. A processing environment receives the input data forwarded by the input policy filter and processes the input data to generate output data A management environment produces an attestation of the processing environment and produces an output provenance based on the input provenance and the attestation. An output policy filter receives the output data and the output provenance and forwards the output data and the output provenance according to at least one output policy.
