Few industries are buffeted from as many strong forces as healthcare. The industry is highly regulated, thus dramatically increasing costs and sometimes even interfering with the ability to deliver healthcare. New drugs, treatments, and medical technologies are so common that keeping track of them can be overwhelming, and incorporating them into patient care or administration can be costly and complicated. On the social side, different groups have different opinions on any given topic and often the right thing to do depends on your point of view. Third party payers add another level of complexity, and competition adds yet another layer of difficulty as organizations seek to grow patient volume by positioning themselves as distinguished in terms of cost, quality, accessibility, and quality of patient experience.

The ability to collect and disseminate individually identifiable microdata is becoming increasingly important in a number of arenas. This is especially true in health care and national security, where this data is considered vital for a number of public health and safety initiatives. In some cases legislation has been used to establish some standards for limiting the collection of and access to such data. However, all such legislative efforts contain many provisions that allow for access to individually identifiable microdata without the consent of the data subject. Furthermore, although legislation is useful in that penalties are levied for violating the law, these penalties occur after an individual's privacy has been compromised. Such deterrent measures can only serve as disincentives and offer no true protection. This paper considers security issues involved in releasing microdata, including individual identifiers. The threats to the confidentiality of the data subjects come from the users possessing statistical information that relates the revealed microdata to suppressed confidential information. The general strategy is to recode the initial data, in which some subjects are "safe" and some are at risk, into a data set in which no subjects are at risk. We develop a technique that enables the release of individually identifiable microdata in a manner that maximizes the utility of the released data while providing preventive protection of confidential data. Extensive computational results show that the proposed method is practical and viable and that useful data can be released even when the level of risk in the data is high.
