N Sandhya, Krishna Gudi, Sunanda Allur · 2014
Information brokering systems (IBSs) connect many organizations via a brokering overlay network, in which the data brokers has responsibility for routing decision for each client queries on behalf of client involvement, based upon the queries details provided by client the routing takes place to the requested data servers, this service ensures less burden on clients in routing and searching process. Information Brokers are also an important target to the attacker and Information Brokers individual takes all responsible in brokering process of IBSs, also many existing IBSs assume that information brokers are trusted thus only adopt server-side access control for data confidentiality. Also privacy of data location and data consumer are important and can still be inferred from metadata exchanged within the IBS. Here a novel approach to preserve privacy of multiple stakeholders involved called Privacy Preserving Information Brokering having two countermeasure schemes namely “automaton segmentation” and “query segment encryption”.
