Abstract:
|
One of the most pressing issues in the confidentiality literature is the quantification of privacy. One proposal, $\epsilon$-differential privacy, has been set forth; however, the selection of an appropriate $\epsilon$ is difficult because its interpretation is unclear. The aim of this work is to provide a measure that is more easily interpreted and to allow for policy debate pertaining to how much privacy is acceptable. Our proposal sets the problem in a hypothesis testing framework and uses the area under the receiver-operator characteristic (ROC) curve as a measure of privacy. This method allows privacy to be compared using one scale, regardless of the privacy preserving mechanism. It also provides an easily interpretable privacy metric.
