Trusted UI authenticated by biometric sensor

Abstract:

The security of a personal image in an apparently trusted UI is improved through the use of a fingerprint sensor hardwired to a Trusted Execution Environment. The personal image may be a complete or partial representation of a fingerprint sensed by the fingerprint sensor enhanced through emphasis of features of the fingerprint. Alternatively, the personal image may be an object whose movement within the UI is controlled responsive to data received from the fingerprint sensor.
