Added Information Value Through Computer Matching of Data]

Information was presented to the National Bureau of Standards' Workshop on Data Administration concerning computer matching, which is the comparison of data that exists in different files that creates new information and represents a measurable value that can be added to the intrinsic value of the information contained in the files that were matched. The purpose of the new information is to detect errors, fraud, and/or internal control problems associated with the management of benefit programs in the federal government. In addition, dollar values can be measured by the savings resulting from the matched information. Illustrations were presented that showed: (1) the movement of technology towards the linkage of files through telecommunications lines; (2) a de facto centralization of data concerning non-government organizations; (3) matches of data on income tested federal programs; and (4) examples of state matches. Some of the concerns related to computer matching were: (1) cost versus benefit; (2) technology and centralization; (3) privacy; (4) security; and (5) other concerns of human error and safety considerations. GAO concluded that matching does represent a delicate balance.
