Abstract:
A method and system for consistent format preserving encryption (C-FPE) are provided to protect sensitive data while the sensitive data is in a domain while allowing encrypted sensitive data to be treated inside the domain as if it were the unencrypted sensitive data. The method includes inserting a transparent coupling into a data flow at a perimeter of the domain, and translating a sensitive data element from an unprotected data element to a protected data element using the transparent coupling such that the sensitive data element is a protected data element within the domain.
