However, even if the microdata are not available directly, disclosure of sensitive information is still possible. We illustrate that an ill-intentioned user could use some commonly available background information to reveal sensitive information using simple linear regression. We demonstrate the real risks from this approach with an empirical evaluation based on a German establishment survey, the IAB Establishment Panel.
