User-Defined Privacy Grid System for T-Broker: A Trust-Aware Service Brokering Scheme Multiple Cloud Collaborative Services
Mr. C.CHAITANYA, Mr. V.N.VENU GOPAL, , ,
To facilitate extensive collaborations, today’s organizations raise increasing needs for information sharing via on-demand information access. Information Brokering System (IBS) a top a peer-topeer overlay has been proposed to support information sharing among loosely federated data sources. It consists of diverse data servers and brokering components, which help client queries to locate the data servers. However, many existing IBSs adopt server side access control deployment and honest assumptions on brokers, and shed little attention on privacy of data and metadata stored and exchanged within the IBS. More importantly, T-broker uses the maximizing deviation method to compute the direct experience based on multiple key trusted attributes of service resources, which can overcome the limitations of traditional trust schemes, in which the trusted attributes are weighted manually or subjectively. Finally, T-broker uses a lightweight feedback mechanism, which can effectively reduce networking risk and improve system efficiency. The experimental results show that, compared with the existing approaches, our T-broker yields very good results in many typical cases, and the proposed system is robust to deal with various numbers of dynamic service behavior from multiple cloud sites.
