Privacy Aware Data Sharing: Balancing the Usability and Privacy of Datasets

Free registration required

Executive Summary

Existing models of privacy assume that the set of data to be held confidential is immutable. Unfortunately, that is often not the case. The need for privacy is balanced against the need to use the data, and the benefits that will accrue from the use of the data. The authors propose a model to balance privacy and utility of data. This model allows both the data provider and the data user to negotiate both requirements until a satisfactory balance is reached, or one (or both) determines such a balance cannot be reached.
