Deciding on a Threshold - Performing a Risk Assessment

One of the challenges in de-identifying data sets is deciding what the appropriate threshold should be. The threshold represents the maximum risk that the data custodian is willing to take. The PARAT tool has a powerful risk assessment expert system that enables the user to choose a threshold.

The expert systems consists of a series of checklists that cover the practices of the data recipient, as well as the characteristics of the data that are being disclosed. It provides a defensible and rationale way to choose a threshold.
