A Method to Improve Data Swapping at the U.S. Census Bureau
Data swapping is one of several disclosure avoidance methods that the Census Bureau implements to uphold confidentiality mandated by law. The Center for Disclosure Avoidance Research (CDAR) is currently studying the use of n-cycle swapping as a means to protect respondent identity in large-scale data. N-cycle swapping, a variant of data swapping, uses permutations of size 'n' to swap data records rather than swapping them in pairs. In this talk, we will discuss the processes surrounding n-cycle swapping, CDAR's current studies and challenges, and future projects and data products involving this disclosure avoidance technique.
