Data obfuscation is frequently utilized interchangeably with data masking. Data obfuscation scrambles data in order to anonymize it. Data obfuscation is fundamental in many regulated industries where personally identifiable data must be shielded from overexposure.
As with data masking, special care should be taken in the use of obfuscation for de-identifying data. Even with identity information obfuscated, key data elements such as age, zip code, and sex may allow for individuals to be re-identified.
