A Work ow Reference Monitor for Enforcing Purpose-Based Policies
نویسنده
چکیده
Purpose is a key concept in privacy policies. Based on the purpose framework developed in our earlier work [11] we present an access control model for a work ow-based information system in which a work ows reference monitor ( WfRM ) enforces purpose-based policies. We use a generic access control policy language and show how it can be connected to the purpose modal logic language ( PML ) to link purpose constraints to access control rules and how such policies can be enforced. We also present a simple implementation of such a reference monitor based on extending eXtensible Access Control Markup Language( XACML ), a commonly used access control open standard.

A Declarative Framework for Specifying and Enforcing Purpose-Aware Policies
Purpose is crucial for privacy protection as it makes users confident that their personal data are processed as intended. Available proposals for the specification and enforcement of purpose-aware policies are unsatisfactory for their ambiguous semantics of purposes and/or lack of support to the run-time enforcement of policies. In this paper, we propose a declarative framework based on a first...
متن کاملEnforcing memory policy specifications in reconfigurable hardware
While general-purpose processor based systems are built to enforce memory protection to prevent the unintended sharing of data between processes, current systems built around reconfigurable hardware typically offer no such protection. Several reconfigurable cores are often integrated onto a single chip where they share external resources such as memory. While this enables small form factor and ...

متن کاملPrivacy Enforcement with an Extended Role-Based Access Control Model
Privacy enforcement has been one of the most important challenges in IT area. Current privacy practices within companies and organizations, e.g. enabling a P3P compliant policy, incorporating a privacy seal program, etc., cannot truly protect consumer privacy. Privacy protection can only be achieved by enforcing privacy policies within an organization’s online and offline data processing system...
