Private-Pond: Outsourced Management of Web Corpuses

With the rise of cloud computing, it is increasingly attractive for end-users (organizations and individuals) to outsource the management of their data to a small number of large-scale service providers. In this paper, the authors consider a user who wants to outsource storage and search for a corpus of web documents (e.g., an intranet). At the same time, the corpus may contain confidential documents that the organization does not want to reveal to the service provider.
