Title:
METHODS AND APPARATUS FOR BIOMETRIC AUTHENTICATION IN AN ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/083495
Kind Code:
A3
Abstract:
Embodiments of the disclosure provide methods and apparatus in which a biometric authentication score generated as the result of a biometric authentication algorithm is compared to a threshold value that can be dynamically varied as required to provide a variable level of security. For example, the threshold value may be varied in dependence on the semantic content of a voice signal, and/or the context in which the voice signal was acquired. Authentication of the signal may be initiated in parallel with speech recognition, such that the appropriate threshold value is only determined after authentication has already begun.
