System and method for enabling the emergency remote override of a hijacked operation of a vehicle, a device or a facility

A method for remotely reestablishing operational control of a function of a device after operational control of the device function has been lost, at least partially, due to malicious interference by a third party, the method comprising steps of:

• integrating an onboard primary controller into the device, wherein the onboard primary controller is adapted to control at least one function of the device;
• providing a base controller adapted to communicate with the onboard primary controller via a first mode of communication in order to provide instructions by which said onboard primary controller is to control said at least one device function;
• and
• integrating an auxiliary controller module into the device, wherein the auxiliary controller is adapted to communicate with the base controller via a second mode of communication different from the first mode of communication between said onboard primary controller and said base controller, such that said auxiliary controller module functions as a backup to temporarily take over control of said at least one device function, in place of said onboard primary controller, when said at least one device function is rendered non-responsive to operator-attempted communication from said base controller to said onboard primary controller,
• wherein communication from said base controller to said auxiliary controller module, via said second mode of communication, relies upon a coded messaging scheme requiring communication of a predetermined specific code, from said base controller to said auxiliary controller module, which activates said auxiliary controller module to disable, and take over control from, said onboard primary controller in response to receipt of said predetermined specific code, and wherein said predetermined specific code is known only by the operator of said base controller and by said auxiliary controller module.
