US Patent 11477150 Servers, method of controlling servers, and non-transitory computer-readable mediums

Disclosed is a server capable of improving convenience for a user at the time of service registration. The server includes a service providing unit which provides a service to an unregistered user who is not registered in the service when the unregistered user accesses the service, and a storage device which stores a service history provided to the unregistered user by the service providing unit. When the unregistered user is registered in the service, the service providing unit allows the unregistered user to use the service while taking over a service history used when the unregistered user is not registered in the service.
