  • Biometric authentication systems and methods
    Patent number: 9152869
    Abstract: Biometric authentication devices, systems and methods are provided. The authentication device includes biometric reader configured for generating raw biometric data indicative of a physiological characteristic of a user; and processor operatively coupled to the biometric reader, the processor being configured for: receiving the raw biometric data, generating derivative biometric data by processing a portion of the raw biometric data relating to a pre-selected aspect of the physiological characteristic, the pre-selected aspect being suitable for identifying the user, the derivative biometric data being indicative of a plurality of instances of the pre-selected aspect in the raw biometric data, generating biometric identification data from the derivative biometric data, the biometric identification data being based upon relationships between the plurality of instances of the pre-selected aspect in the raw biometric data, and using the biometric identification data to identify the user.
