Policy based Security Framework in Semantic Web

Semantic Web (SW), an extension of Web2.0 which can integrate various application and system such that data can be processed by machine instead of human using RDF, SPARQL, OWL technologies. With the passage of time advancement made in technologies which can provide dynamic support and interactions such as DAMLS [13], RDF AND RDFS, OWL, SWRL.As we are shifting towards making a system which is user interaction free, meet new security challenges [14]. Security is becoming prime important and a crucial factor in making an autonomous system, who will able to provide dynamic support and interaction of various clients and agents on a large scale? Success of Semantic Web depends on the way security is handle at various layers. Here, we are providing a policy based security framework containing Knowledge base, Distributed policy Management. Moreover, we have also provided a table with key points of SW and problem addressed in each research article.
