Abstract

Extensible Access Control Mark-Up Language (XACML) based solutions for dynamic privacy policy management and decision enforcement is proposed in recent research to enhance the accuracy of the component like Policy Enforcement Point (PEP) and Policy Decision Point (PDP). Composition plan will be generated where any service WS1 which depends on another service WS2. To manage data privacy, Web Services defines a privacy policy for each instance in its OWL repository. Each repository manages data access through SPARQL endpoint. A dynamic, semantic-based privacy policy management framework is proposed in our system on the top of the XACML reference architecture for policy-based access control. XACML is a protocol of communication between a PDP and PEP used for context handling. The context handler accepts the request from an XACML formed by PEP and sends it to the PDP. The PDP uses the attributes to evaluate policies and it returns the final decision.
