identifiable data

Data which are either (a) directly connected to name/other identifiers, or (b) indirectly connected via a study number or other coding scheme. Even if neither condition applies, it might still be possible to infer identity via descriptors such as age, gender, ethnicity, etc.

Note that this is different from the definition of “identifiable” in the HIPAA regulations about health care regulations. Information that is considered an “identifier” by HIPAA regulations may not meet the federal human subjects definition of “identifiable”.
