Lightweight Privacy-Preserving Peer-to-Peer Data Integration

Peer Data Management Systems (PDMS) are an attractive solution for managing distributed heterogeneous information. When a peer (client) requests data from another peer (server) with a different schema, translations of the query and its answer are done by a sequence of intermediate peers (translators). There are two privacy issues in this P2P data integration process: answer privacy: no unauthorized parties (including the translators) should learn the query result; mapping privacy: the schema and the value mappings used by the translators to perform the translation should not be revealed to other peers. Elmeleegy and Ouzzani proposed the PPP protocol that is the first to support privacy-preserving querying in PDMS.
