If a dataset removes all information except for, say, a user's fingerprints, meaning the only information stored in the anonymous dataset is an image of a fingerprint. The nature of fingerprints prevents them from meeting this requirement, as stated, which effectively eliminates any research that can be done with the data. Given that the only way the dataset could be linked to the original user is if an attacker already had access to the source data, how is this regulation benefiting anyone?
