I think the correct term to fill in the blank would be personal. For extra security, some of the smart cards today store personal data providing personal identification for authenticating the user's transactions. Another name for smart cards is integrated circuit card.
I believe the answer is: biometric data
Biometric data refers to a form of data that required some sort of biological component as a form of authorization to increase the level of security. This could be seen in smart cards that require finger prints of the owners in order to be activated/used.
