A Secure Approach for Privacy-Preserving in Information Brokering System using Query Forwarding

Madhuri D. Dhayarkar, Ram B. Joshi

There is an increasing need for information sharing via on-demand access in different organizations. Information Brokering Systems (IBSs) have been introduced to connect large-scale lightly-associated data sources. This system includes brokers that are responsible for routing decisions to direct client queries to the requested servers where data is located. Existing IBSs consists of brokers that are trusted and thus only adopt server-side access control for data confidentiality. However the privacy of location of data and information about consumer can still be concluded from metadata (such as query and access control rules) exchanged within the brokering system, thus the protection of the metadata is a major issue in IBS. The proposed scheme presents an overview on information sharing in distributed environment through information brokering system and problems associated with it thus providing scope for healthcare information systems. The objective is to overcome two attacks- attribute correlation attack and inference attack providing security enforcement and to provide two countermeasure schemes namely automaton segmentation and query segment encryption scheme. Thus central authority is necessary for routing decision making responsibility among a selected set brokering servers.
