1. A system comprising:
a database to store device history data associated with identifiers of different devices that are assignable to different users; and
a processor connected to the database, the processor to, in response to a command, deterministically modify a first identifier of a device that is to be reassigned from a first user to a second user to obtain a second identifier that is different from the first identifier; and
the processor further to query the device history data using the second device identifier to obtain second events of the device history data related to the second user as distinguished from first events of the device history data related to the first user.
