human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "an analytical survey of provenance sanitization"):
  Abstract: Security is likely becoming a critical factor in the future adoption of provenance technology, because of the risk of inadvertent disclosure of sensitive information. In this survey paper we review the state of the art in secure provenance, considering mechanisms for controlling access, and the extent to which these mechanisms preserve provenance integrity. We examine seven systems or approaches, comparing features and identifying areas for future work.

Includes members:
  Member "a propagation model for provenance views of public private workflows":
    also connected through other hyperedges:
      (none)
  Member "surrogate parenthood protected and informative graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a core calculus for provenance")
  Member "provenance views for module privacy":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "viewpoint personal data and the internet of things it is time to care about digital provenance")
