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.
