Secure factory data generation and restoration

One or more non-transitory machine readable media storing instructions which, when executed by one or more processors, cause the one or more processors to perform operations for managing factory-generated data for an electronic device, the operations comprising:

• persistently storing a production version of calibration data generated for one or more sensor modules of the electronic device via a first networked server device, each of the one or more sensor modules associated with a hardware component of the electronic device, the calibration data associated with the one or more sensor modules via a module identifier that is unique to each individual sensor module;
• transmitting the calibration data to one or more non-volatile storage systems via a network connection of the first networked server device;
• retrieving, via a network connection of a second networked server device, the production version of the calibration data associated with the one or more sensor modules from the one or more non-volatile storage systems;
• assembling a set of factory data for the electronic device, the factory data including the calibration data and associated with the electronic device via a device identifier that is unique to the electronic device;
• authenticating, at a sealing server device in response to a request from the electronic device, the set of factory data for the electronic device, the authenticating performed via the module identifier of each sensor module;
• creating a cryptographic association between the set of factory data and the electronic device after the authentication;
• and
• storing a manifest of the cryptographic association on the electronic device.
