An encryption scheme might, that is, guarantee that an adversary can’t extract an encoded Social Security number; but it might still allow the adversary to extract the last four digits of the number. Similarly, it might prevent an adversary from determining a subject’s age; but it might allow the adversary to deduce that, say, the subject is between 30 and 40 years of age.
