Abstract: Systems and methods may be used for operation of a hardware fingerprint processing device. A method may include receiving an update including a fingerprint authentication algorithm, verifying a digital signature of the fingerprint authentication algorithm, and in response to verifying the digital signature, loading the fingerprint authentication algorithm into the memory. The loaded fingerprint authentication algorithm may be sued to authenticate a user. For example, a verification method may include receiving information corresponding to an image of a fingerprint, determining whether the fingerprint is authenticated using the fingerprint authentication algorithm, and optionally outputting an indication of whether the fingerprint is authenticated.
