Abstract : The LINDO project proposes an open system dedicated for managing distributed multimedia contents by focusing on their indexing, storage and retrieval. The objective is to provide efficient information retrieval with minimal processing costs. This was achieved through the proposal of an efficient decentralized content indexing mechanism. Considering a pervasive context, where users are mobile and acquire access to sensitive data sources, adding an access control layer on top of the LINDO architecture becomes essential. In this paper, we confront the access denial problems and we propose to apply an adaptive mechanism that rewrites access requests while considering the user’s context and situational information. This operation is performed through PSQRS, a query-rewriting system that manages access based on the RBAC model and realizes decision-making using XACML.
