What is dynamic enroll and why is it a security risk?
Dynamic enroll is the process of only partially initially enrolling a user’s fingerprint, and then subsequently adding biometric data to the template, as the biometric card is used.
This method of enrollment, known as dynamic enroll, is leaving a huge security hole in the use of fingerprint biometrics and puts users at risk as a result. If a template can be changed, then over time the fingerprint biometric data originally enrolled onto the card can be gradually replaced. These ‘climbing attacks’ mean that potential fraudsters could use a card that has only been partially enrolled and add their own biometric fingerprint data to it.
