Abstract:
|
The Bureau of Transportation Statistics (BTS) is revising its confidentiality policy, which is based on its legislative mandate (49 U.S.C. 111[i]) to protect individually identifiable information. Because the field of statistical disclosure limitation (SDL) research is still evolving, BTS wanted to take advantage of the latest SDL research in updating its confidentiality policy and practices. To this end, BTS has undertaken research that seeks to develop a method to limit disclosures in complex, multi-dimensional (up to five) tables that contain a hierarchical structure. This research will also offer a new way of protecting confidentiality, while at the same time increasing access to data. Background information on BTS confidentiality legislation and policy will be provided along with a brief review of the literature on the current state-of-the-art disclosure limitation methods for tabular data. An overview of BTS present research efforts and initial findings will be presented.
