Providing user authentication services using biometric hardware and software technology for consolidating biometric modality using the live physiological signal originating from the nervous system to determine if a user is present at the time of authentication/identification, for prevention of spoofing attacks as it detects micro-vibrations in a user's hand, for detection of micro-vibrations in a user's hand that represents neuro-muscular activity that cannot be imitated by another user as the micro-vibrations are never the same, for use of sensors already present in standard mobile devices
