Secure data integration: A formal concept analysis based approach

Abstract

Integrating and sharing information, across disparate data sources, entail several challenges: autonomous data objects are split across multiple sources. They are often controlled by different security paradigms and owned by different organizations. To offer a secure unique access point to these sources, we propose two-step approach based on Formal Concept Analysis. First, it derives a global vision of local access control policies. Second, it generates a mediated schema and the GAV/LAV mapping relations, while preserving the local source properties such as security. © 2014 Springer International Publishing Switzerland.
