Delegating or transferring of access to resources between multiple devices

摘要

A gatekeeper device delegates an ability to access a resource to an access device by transmitting metadata, which includes access information for accessing the resource. The access device uses the metadata to retrieve the associated resource from a resource server. By transmitting the metadata in lieu of the resource, flexible use of the resources is implemented while enabling compliance with various restriction schemes. The system may condition the delegation or transfer of resource access on one or more factors, such as proximity between the gatekeeper device and the access devices. Using information about an access device, the resource server may optimize the resources for the receiving access device.
