Claim One:
1. A speaker recognition system, comprising: a tamper-resistant element, comprising a first processor and a memory; and a second processor, provided separate from the tamper-resistant element; wherein: the second processor is connected to a source of audio samples, and the second processor is provided with a Universal Background Model for speaker recognition; the second processor is configured such that, during an enrollment phase, samples received from an enrolling user are compared with the Universal Background Model in the second processor to form data representing speaker information for the enrolling user; the tamper-resistant element is configured for receiving the data representing speaker information for an enrolling user from the second processor, and the memory of the tamper-resistant element is configured for storing said data representing speaker information for the enrolling user, such that the enrolling user becomes an enrolled user; and the second processor is configured such that, during a verification phase, samples received from a speaker subject to verification are compared with the Universal Background Model in the second processor to form data representing speaker information for the speaker subject to verification; and wherein the tamper-resistant element is configured for receiving the data representing speaker information for the speaker subject to verification from the second processor, and the processor of the tamper-resistant element is configured for comparing the data representing speaker information for the speaker subject to verification with the data representing speaker information for the enrolled user, enabling a determination based on said comparison whether the speaker subject to verification is the enrolled user.
