Any information that can be used to distinguish one person from another and can be used for de-anonymizing anonymous data can be considered personally identifiable data. 3. Data are identifiable if the information contains the name of an individual, or other identifying items such as birth date, address or geocoding. Data will be identifiable if the information contains a unique personal identifier and the holder of the information also has the master list linking the identifiers to individuals. Data may also be identifiable because of the number of different pieces of information known about a particular individual.
