  • Publication number: 20200349490
    Abstract: Technologies are provided for context-based instruction delivery to field agents. In some examples, one or more context-sensitive criteria may be extracted from an instruction contained in a message. The message and the criteria may then be transmitted to multiple field agent devices. In response to receiving the message and the criteria, a field agent device may determine whether a legitimate agent is present and the criteria are satisfied. If a legitimate agent is present and the criteria are satisfied, then the agent device may provide the instruction in the message to the legitimate agent. On the other hand, if a legitimate agent is not present, or if the device and/or agent fail the criteria, then the device may ignore the instruction.
