National Institute of Statistical Sciences Data Confidentiality Technical Panel

Résumé du livre

NCES asked the National Institute of Statistical Sciences (NISS) to convene a technical panel of survey and policy experts to examine the NCES current and planned data dissemination strategies for confidential data with respect to: mandates and directives that NCES make data available; current and prospective technologies for protecting and accessing confidential data, as well as for breaking confidentiality; and the various user communities for NCES data and these communities' uses of the data. The principal goals of the technical panel were to review the NCES current and planned data dissemination strategies for confidential data, assessing whether these strategies are appropriate in terms of both disclosure risk and data utility, and then to recommend to NCES any changes that the task force deems desirable or necessary. The NISS technical panel delivered its report to NCES in 2008. The report included four principal recommendations, the first three of which confirmed existing NCES strategies and practices. They are: (1) The technical panel recommended that all NCES analyses and publications be based on restricted databases produced by applying data swapping operations to original data as collected and edited; (2) The technical panel also recommended that access to restricted databases be controlled under license from NCES; (3) The panel recommended that NCES produce public databases whenever possible (by applying further appropriate statistical disclosure limitation techniques) and provide access to the public databases electronically by means of a data access system (DAS); and (4) The panel recommended that NCES tailor the user interfaces of data access systems to user communities. Appended is The Czech Auto Worker Database (Contains 1 table, 7 figures, and 15 footnotes.).
