Title: Increasing data quality with loose associations in data outsourcing environment

Date: 04.12.2018, IFI 1.101, 14:00-16:00

Abstract: Outsourcing of data storage is increasingly common, but poses major problems for data utility and confidentiality.  This project aims to discover how tuples in fragments can be grouped for producing loose associations so to increase the utility of queries executed over fragments. It creates a framework to perform grouping and produce loose associations that satisfy information protection goals while achieving utility for queries. The outcomes of the project are to formally specify and develop a minimal fragmentation model to validate loose association rules while minimising data leakage risks. The outcomes will benefit Australians through enabling sharing and linking increasingly large datasets securely and cheaply.
