Abstract
A method for desensitizing character strings comprises ordering an original set of character strings and generating a tree structure that has nodes corresponding to the ordered set of sensitive strings. The sensitive characters on the nodes of the tree are then desensitized in depth-first order such that a set of desensitized strings is generated that preserves the ordering of the original sensitive set.
