US Patent 9967248 System for authenticating and processing service requests

Described are techniques for establishing secure communication channels between user devices and service providing devices. Correspondence between a request received from a user device and security data may be used to determine that the user device has provided a valid access credential. The access credential may be replaced with a subsequent access credential after use. Correspondence between the request and service data may be used to determine that the request may be processed by the receiving service and that the user device has the permissions necessary for the request to be processed. Portions of the request that meet these criteria may be provided to the service. The secure communication channel may also be used to provide the response from the service to the user device.
