In business organizations, person-specific data are collected as part of service re­ quirements from customers or data providers. To maintain the privacy of these per­ sonal data from intra-organizational or external unauthorized access, an Role-based access control (RBAC) extension with privacy purposes has been introduced. Re­ search on role-based access control and privacy has been conducted. Despite all this research, not much investigation into efficient ways to store person-specific data with privacy labels has been conducted. To the best of our knowledge, there is no such re­ search to analyze the characteristics and impact of different storage patterns on RBAC with privacy purposes. In this thesis, we propose some storage schemes for extended RBAC with privacy purpose in a relational database environment. Moreover, we ana­ lyze the performance characteristics and impact of different SQL operations according to different storage schemes for the extension of RBAC with privacy purposes.
