Extending from the previous semantic privacy-preserving model, the authors propose wide-scale super-peer data integration and protection architecture. Any user from a super-peer domain can contribute new data, schema, or even mappings for other super-peer domains to integrate the information. Each super-peer domain is essentially a mediator-based data integration system, where an agent at the super-peer performs semantic local mappings to manage a set of its local peers endowed with shareable relational data sources. Semantic global mappings are also possible from the current super-peer to interlink with other super-peers located in their super-peer domains.
