Math problems aren't technical problems? Do you mean it's a mathematically-impossible technical problem? Noise and obfuscation can be added to the data such that the unique person it identifies doesn't exist. For example changing the dates by some limited random amount. Replacing values with roughly-similar choices (replace engineer with scientist, replace Mexico with el Salvador, etc.) The technical problem is doing that in a way that doesn't harm its research value, never allows the final set of possible similar identities to be below some lower limit, and can't be reversed of course.
