Abstract Biometric key technology is the organic combination of biometric
encryption technology and traditional cryptography. Biometric key
can directly encrypt data or encrypt key, with the character of
portable use and not easily being stolen, forgotten and broken. This
article provides an algorithm for generating key based on the
fingerprint feature bit-strings, extracting fingerprint feature
information with bit-strings form as first step, generating key by
the combination of this feature information and BCH error correcting
code secondly. Experiments show that the algorithm can generate
stable key of encryption on the premise of protecting the user's
fingerprint information. It can further improve the security
strength and reach two-factors protection if the biometric key is
stored in the smart card, which has certain practical value.
