US Patent 9826083 Automatic delegation control for device sharing

A computing device receives voice input that includes first voice input from a first user and second voice input from a second user. The computing device may determine, based at least in part on the received voice input, a change in possession of the computing device. The computing device may determine, based at least in part on the first voice input and the second voice input, delegation of the computing device from the first user to the second user. The computing device may, in response to determining the change in possession of the computing device and the delegation of the computing device, change at least a level of access to functionality of the computing device from a first level of access to a second level of access.
