It is surprising that so much can be identified by deduction from data. You may assume that you can safely distribute partially masked data for reporting, development or testing when the original data contains personal information. Without this sort of information, much medical or scientific research would be vastly more difficult. However, the more useful the data is, the easier it is to mount an inference attack on it to identify personal information.
