Abstract
A method for handling biometric templates is disclosed for an authenticating device applying biometric authentication. The method comprises acquiring a set of biometric data associated with a prospect user, and acquiring a decryption key (associated with an encrypted biometric template associated with an enrolled user of the authenticating device) from a key carrying device external to the authenticating device responsive to the key carrying device being in a vicinity of the authenticating device. The method also comprises retrieving, from a storage medium, at least a part of the encrypted biometric template associated with the enrolled user, decrypting the retrieved part of the biometric template using the acquired decryption key and performing an attempt to authenticate the prospect user as the enrolled user based on a comparison between the acquired set of biometric data and the decrypted part of the biometric template.
