....other data holders, statistics offices are also facing tremendous demand for entity specific data for applications such as data mining, cost analysis, fraud detection and retrospective research. But many of the established statistical database techniques, which involve various ways of adding noise [24] to the data while still maintaining some statistical invariant [25, 26] often destroy the integrity of tuples and so, for many new uses of data, these established techniques are not appropriate. I will further discuss disclosure limitation techniques commonly employed to protect the ....

....11, 12] Like other data holders, statistics offices are also facing tremendous demand for entityspecific data for applications such as data mining, cost analysis, and retrospective research. But many of the established statistical database techniques, which involve various ways of adding noise [13] to the data while still maintaining some statistical invariant [14] often destroy the integrity of tuples [15] Even in cases of tabular releases, statistical offices are finding their established practices failing given the increase of entity specific data and the proliferation of computing ....

....other security procedures. The advantage of the methods is that available general software is often straightforward to apply. The associated research problems relate to how seriously analytic properties are compromised. Additive noise is known to preserve some of the analytic properties of files (Kim 1986, 1989; Fuller 1993) Research problems are whether general software can be developed and whether files are free of disclosures. Combinations of additive noise and limited swapping have been used by Kim and Winkler (1995) and Winkler (1998) Data perturbation methods (Tendick and Matloff 1994) are ....

....give out public use files. When agencies first produce the public use microdata, they should check it for analytic validity. Some methods of producing the public use data may have more of a tendency to yield analytically valid files and make checking for analytic validity easier. Additive noise (Kim 1986, 1990) and the generalizations (Sullivan and Fuller 1990, 1991; Fuller 1993, Little 1993) have a strong tendency to produce analytically valid files. The files that are produced via noise addition have generally not been confidential because a (possibly) small percentage of records can be ....

....need to be used in correctly matching different pairs of records. These modern record linkage methods are often in commercially available code that can be applied by relatively naive users in re identification experiments. With the more sophisticated ways of producing publicuse microdata (e.g. Kim 1986, Fuller 1993, Kim and Winkler 1995, DeWaal and Willenborg 1996) re identification is considerably more difficult but possible if the individual performing the work is experienced in record linkage and able to write certain types of sophisticated computer code. At some point in the near future, ....

....policy regarding earned income credit and other benefits. The microdata is masked in such a manner that both Bureau of the Census and IRS confidentiality restrictions are met. No masked IRS quantitative data can alone be used in reidentifications. The main methodology is an additive noise approach (Kim 1986) for masking multivariate normal data that preserves confidentiality and can preserve many essential characteristics of the data such as means, variances, and correlations. The CPS and IRS data of the application are known to be approximately 2 multivariate normal. While the methodology has ....
....it is easier to minimize the chance of reidentification. We primarily need be concerned with higher income individuals or those with distinct characteristics that might be easily identified even when sampling rates are low. 2.2. Masking Methodology Masking is via an additive noise approach (Kim 1986, see also Sullivan and Fuller 1989, Sullivan and Fuller 1990, and Little 1993) Adding random noise with the same correlation structure as the original unmasked data is currently the only method (Little 1993) that preserves correlations. Appendix A.3 allows us to determine means and covariances ....
