Abstract: A method for picture processing is described. A first tracking area is obtained. A second tracking area is also obtained. The method includes beginning to track the first tracking area and the second tracking area. Picture processing is performed once a portion of the first tracking area overlapping the second tracking area passes a threshold.

Abstract: Disclosed is a mobile device to provide continuous and discrete user authentication. The mobile device may include: a contextual sensor; a soft biometric sensor; and a processor. The processor may be configured to: implement a background authentication process in a continuous manner based upon a soft biometric input from the soft biometric sensor and a contextual input from the contextual sensor; determine an anomaly event; and based upon the anomaly event, request a discrete authentication input from the user.

Abstract: One feature pertains to a method for extracting a secret key during a secure boot flow of an integrated circuit. Specifically, the secure boot flow includes powering ON a first volatile memory circuit to generate a plurality of initial logical state values, deriving secret data based on the plurality of initial logical state values, storing the secret data in a secure volatile memory circuit that is secured by a secure execution environment (SEE), clearing the plurality of initial logical state values in the first volatile memory circuit, executing a cryptographic algorithm at the SEE to extract a secret key based on the secret data, and storing the secret key in the secure volatile memory circuit. The secure boot flow controls access to the first volatile memory circuit to secure the secret data and the plurality of initial logical state values from the insecure applications.
