Abstract: Systems and methods for storing and recovering data for a device are described. In one embodiment, factory generated calibration data can be generated, sealed and restored securely even if two sensors in two different devices, such as a first ambient light sensor and a second ambient light sensor have the same sensor identifier. In one embodiment, a device transmits a database key to cause storage or recovery of the calibration data, and the database key includes a sensor identifier and a public cryptographic key of the device.

Abstract: In some examples, a method comprises determining, at an electronic device having a first component of a first component type, a unique identifier associated with the first component. In some examples, in accordance with a determination that the unique identifier does not match the expected identifier of the component of the first component type in the electronic device, determining that the first component associated with the unique identifier satisfies one or more eligibility criteria. In some examples, in accordance with the determination that the first component associated with the unique identifier satisfies the one or more eligibility criteria, authenticating an association of the first component with the electronic device, including updating an installation counter associated with the first component, and updating the expected identifier for the component of the first type based on the unique identifier of the first component.
