Abstract
A server is configured to receive an input file or table that includes a number of data elements, where the data elements include some sensitive data elements of different types; identify each of the different types of sensitive data elements; identify a subset of the sensitive data elements that corresponds to each of the different types of sensitive data elements; simultaneously perform data masking operations on the sensitive data elements to create masked sensitive data elements, where a separate one of the data masking operations is performed on each of the subsets of the sensitive data elements; generate an output file or table that includes the data elements from the input file or table, where the sensitive data elements, of the input file or table, are replaced with the masked sensitive data elements; and output or store the output file or table.
