Limiting Disclosure in Hippocratic Databases

چکیده
We present a practical and efficient approach to incorporating privacy policy enforcement into an existing application and database environment, and we explore some of the semantic tradeoffs introduced by enforcing these privacy policy rules at cell-level granularity. Through a comprehensive set of performance experiments, we show that the cost of privacy enforcement is small, and scalable to large databases.

In this paper, we propose a flexible framework for the negoti...

متن کاملThe Hippocratic File System: Protecting Privacy in Networked Storage
Privacy protection is increasingly difficult in today’s information society. In this paper, we look at an important link in the chain of information protection: the file system, and propose mechanisms to enhance the disclosure control of personal data. The scheme, called the Hippocratic File System, stores personal data’s purpose and use limitation as the data’s label, propagates the label as t...
