SUCCINCT ACCESS CONTROL POLICIES FOR PUBLISHED XML DATASETS
english

2008 Proceedings of the Tenth International Conference on Enterprise Information Systems   unpublished
The role-based access control (RBAC) model provides a flexible method for specifying such policies.  ...  We consider the setting of secure publishing of XML documents, in which read-only access control policies (ACPs) over static XML datasets are enforced using cryptographic keys.  ...  ROLE BASED ACCESS CONTROL In this section, we first describe roles and then use roles to define the document-level PRBAC.  ...

The policy based access control mechanism is enhanced to support dynamic data management technique. Data insert, delete and update operations are connected with the partition management mechanism.  ...  Role-based Access Control (RBAC) allows defining permissions on objects based on roles in an organization. Top Down Selection Mondrian (TDSM) algorithm is used for query workload-based anonymization.  ...  Hence, we propose a family of Privacy-aware Role Based Access Control (PRBAC) models that naturally extend classical RBAC models to support privacy policies.  ...
