Abstract:
1. A method of protecting a sensitive data element within a domain, the method comprising: inserting a transparent coupling into a data flow at a perimeter of the domain, wherein the data flow through the transparent coupling includes the sensitive data element; and translating the sensitive data element from an unprotected data element to a protected data element using the transparent coupling such that the sensitive data element is configured as the protected data element within the domain; encrypting the sensitive data element using an encryption mechanism that preserves the syntax, internal semantics and coherence of the unprotected data element of the sensitive data element after translation to the protected form, wherein the protected data element includes an encrypted element; using one or more secret keys to encrypt the sensitive data element; wherein encrypting the sensitive data element includes consistently encrypting the sensitive data element to a corresponding encrypted element which is substantially the same each time the corresponding sensitive data element is encrypted; and producing the corresponding sensitive data element using the corresponding encrypted element and the one or more secret keys.
