A DATA OBFUSCATION SYSTEM, METHOD, AND COMPUTER IMPLEMENTATION OF DATA OBFUSCATION FOR SECRET DATABASES

摘要

A data obfuscation system, method, and computer implementation via software or hardware that allows a legitimate user to gain access via a query to data of sufficient granularity to be useful while maintaining the confidentiality of sensitive information about individual records. Output values of a data request are obfuscated in a repeatable manner, via the use of an Obfuscating Function (OF), whilst maintaining the amount of obfuscation within a range so that the transformed values provide to a user information of a prescribed level of granularity. The data obfuscating system and method is particularly applicable to databases. The data obfuscation engine may be implemented in hardware and/or software within a stand alone or distributed environment.
