Abstract: A method, a device and a system for protecting a biometric feature template are provided, which belong to the recognition field, wherein the method includes: encrypting a user biometric feature data by using a key, and generating the encrypted biometric feature data; binding the data of the user biometric characteristic with the key, and generating a biometric key corresponding to the encrypted biometric feature data. The present invention encrypts the biometric feature data by using a conventional key, binds the data of the user biometric characteristic with the conventional key, and generates the biometric key corresponding to the encrypted biometric feature data; thereby the security and the reliability of the biometric feature data protection could be improved, meanwhile, the security and the reliability of the biometric certification could be improved as well.
