Abstract

A method of data processing that converts a set of restricted terms, which is considered prohibited for use in source files, into an encrypted form, which prevents unauthorized users from reading the set of restricted terms. Further, the terms from a selected source file are encrypted with the same algorithm that was used on the set of prohibited terms. Then, a determination is made if the selected source file has one or more of the encrypted, restricted terms. In response to determining that the selected source file has one or more of the encrypted, restricted terms, an indication is given that the selected source file has one or more of the encrypted, restricted terms.
