Personally identifiable information can include direct identifiers such as names and account numbers, as well as combinations of indirect attributes that distinguish one person. The exact legal scope varies by jurisdiction and context.
Artificial intelligence systems should minimize access to this information and protect it through redaction, encryption, permissions and retention rules. Removing obvious identifiers may not be sufficient if remaining details can still be linked back to an individual.
