Abstract
Distributed, consistent utility-preserving data masking is provided by retrieving an original value from a data table; initiating a communication with a mapping service to ascertain whether or not a masking table of the mapping service includes a fictionalized value associated with the original value; when the masking table does not include a fictionalized value associated with the original value, producing a fictionalized value for the original value wherein the fictionalized value preserves at least one utility function of the original value, updating the mapping service to include the fictionalized value in the masking table, and applying a first masking operation by replacing the retrieved original value with the fictionalized value.
