Patent attributes
An embodiment may involve receiving, by a computing system, a message from a wireless service provider system. The computing system may include one or more computing devices located, e.g., in the trusted cloud. The message may contain a service-provider-based identity of a client device, an indication that the service-provider-based identity has been authenticated by the wireless service provider, and a code that the client device obtained from a remote machine proximate to the client device. The computing system may generate an anonymized identity of the client device based on the service-provider-based identity. The computing system may verify that a task associated with the code is within the authorized capabilities of the anonymized identity. Possibly based on the code (and perhaps other information as well), the computing system may transmit an instruction to the remote machine. The instruction may direct the remote machine to perform the task.
