We study the problem of concealing functionality of a proprietary or private module when provenance information is shown over repeated executions of a workflow which contains both public and private modules. Our approach is to use provenance views to hide carefully chosen subsets of data over all executions of the workflow to ensure Γ-privacy: for each private module and each input x, the module's output f(x) is indistinguishable from Γ--1 other possible values given the visible data in the… CONTINUE READING
