Data masking with isomorphic functions

Abstract:

A method of masking data includes disabling, by one or more processors of a computer system, operation of a data structure that includes at least one data index. The method includes masking, by the one or more processors of the computer system, the data structure in a table with an isomorphic function, and enabling, by the one or more processors of the computer system, operation of the data structure.
