Implementation of Data Privacy and Query Optimization in Data Providing Service Composition

Rashmi Kulkarni and Amit Chougule

Data providing services allow query like access to organizations data via web services. The invocation of DP service results in the execution of a query over data sources. In most cases users queries require the composition of several services. The RDF based query rewriting algorithm is used for DP services composition which has limitation that, it is unable to provide security for a confidential data which is represented in RDF graph. Hence the proposed system will use RDF Encryption in which confidential data in a RDF-graph will be encrypted for a set of recipients while all non-sensitive data remain publicly readable. Also the proposed system will use query optimization technique which will reduce the execution cost.

Keywords: RDF, RDFS, SPARQL.
