Claim 16:
17. A second device, comprising:
an interface for receiving an audio signal representing speech forwarded from a first device, and for receiving a first hash value calculated in a first data integrity check operation forwarded from the first device, the first device for performing a speaker recognition process on the audio signal; and
a processor for:
performing a second data integrity check operation on the audio signal forwarded from the first device, the second data integrity check operation comprising calculating a second hash value from the received audio signal using the same method that is used by the first data integrity check operation;
performing a speech recognition function on the audio signal forwarded from the first device; and
determining if the second hash value calculated in the second data integrity check operation matches the first hash value calculated in the first data integrity check operation forwarded from the first device;

wherein the second device is configured to use a result of performing a speech recognition function on the audio signal forwarded from the first device only if the second hash value calculated in the second data integrity check operation matches the first hash value calculated in the first data integrity check operation forwarded from the first device.
