In this presentation, we will discuss statistical methods for estimating the re-identification risk.
We will discuss both individual and global measures for risks of re-identification. A global measure
provides a single risk value for the entire micro data file to be released whereas an individual measure
gives re-identification risk at level of the individual record. We will illustrate the application of these methods in a VA Rheumatoid Arthritis (VARA) Registry data. VARA data was de-identified according to HIPAA “Safe Harbor” standards.
