Abstract:
According to Article 12 of The Universal Declaration of Human Rights, privacy is a right of an individual. Privacy is a growing concern because the private information of a person is easily available and accessible due to advancement in technology. Since databases are the primary storehouses of data, it has become increasingly important that database systems protect privacy. A breach in privacy may happen for many reasons not limited to: a lack of awareness of the person providing personal information, unnecessary personal information collected and used by the data collector, and the lack of security leading to personal information leakage. A database needs additional features that enforce privacy.
Our work presents a privacy catalogue system design for a relational database management system (RDBMS). The design includes the predicates identified in a data privacy taxonomy by Barker et al., such as purpose (p), visibility (v), granularity (g) and retention (r). The aim here is to propose a normalized and implementable design for an RDBMS. The work includes a study of privacy predicates representation, the basic design of system tables, query processing, an analysis of the design and a partial implementation. Since additional privacy features affect query processing, an algorithm for the SELECT process is described and implemented. An alternate design has been suggested as well to fully consider other design possibilities.
