US Patent 11108779 Time-limited access to configuration settings

Broadly speaking, embodiments of the present techniques provide methods and apparatus to implement a time-limited configuration settings hierarchy. The time-limited configuration settings hierarchy introduces a temporary override setting that allows a fail-back to a prior setting after the expiry of a time period. This allows temporary users of IoT devices to have much higher levels of privilege over configuration settings, as an automatic revocation of the permission and reversion to the previous settings is guaranteed on the expiry of the specified time period.
