Abstract
The binding of the user's identity and biometric feature data to an entity is provided by an authority through a digitally signed data structure called a biometric certificate. Therefore, the main goal (or contribution) of this work is to propose a simple method for generating biometric digital key with biometric certificate on fuzzy fingerprint vault mechanism. Biometric digital key from biometric data has many applications such as automatic identification, user authentication with message encryption, etc. Therefore, this work analysis the related existing scheme and proposes a simplified model where a general fuzzy fingerprint vault using biometric certificate with security consideration.
