Abstract: An electronic device has a lower power state in which power to a storage device is disabled. Predetermined information stored in a memory is useable to unlock the storage device during a procedure to transition the electronic device from the lower power state to a higher power state. The predetermined information is different from a credential for use in unlocking the storage device.

Abstract: A device platform, in some examples, comprises a security processor that may create a private/public cryptographic key pair, and data representing evidence of creation of the key pair, provide access to the key pair and data from an operating system component of the device platform, where the public key part of the key pair may be used to verify management commands. The device platform may validate the key pair and data in a trusted execution state.

Abstract: According to an example, at least one user in proximity to a display is detected with a camera. A primary user and eye gaze are determined. The location of a secondary user relative to the display is calculated, and an active screen area and an inactive screen area based on the eye gaze are determined. A first angle and a first brightness for the active screen area and a second angle and a second brightness for the inactive screen area based on the location of the secondary user are calculated, and focus area boundaries for the active screen area based on the location of the secondary user are calculated. The first angle, the first brightness, and the focus area boundaries are applied to the active screen area, and the second angle and the second brightness are applied to the inactive screen area.

Abstract: An authentication system in accordance with an example includes an image capture device to scan an object. The authentication system also includes an authentication module to identify imperfections in the object based on the scan, to generate model data based on the identified imperfections, and to authenticate the user based on a comparison of currently identified imperfections to the model data.

Abstract: In an example, there is provided a method for attesting to a management state of a device platform configuration, based on a signed data structure that represents a device management status and a time-based value from a secure cryptoprocessor of the device. The signed data structure is sent to a management system for validation based on a comparison to the state of the cryptoprocessor at the time of signing the data structure.

Abstract: Examples herein disclose erasing data from a target device based upon an authentication of an erase command. The examples receive an erase command during execution to boot strap information and authenticate the erase command. Upon the authentication of the erase command, the examples erase data from the target device prior to completion of execution of boot strap information.
