Abstract: A multifunction peripheral (MFP) includes user selectable functions that call home applications on the device that direct it to work cooperatively with cloud service providers. To avoid requiring users to login to each cloud service each time they use it, they are registered with an authorization server to establish and grant identity and authorization tokens. When a user logs in to an MFP, they are redirected to login to the authorization server which then sends tokens to the MFP identifying the user and their permissions and licenses. Home applications associated by the tokens are displayed for selection. Each time a home application using a cloud service is selected, a background application sends the user's session tokens with a service request to an associated cloud service resource server. The resource servers processes authenticated requests and return the result to the MFP which completes the selected home application function.
