Abstract: A touch sensor system includes touch sensors, drive-sense circuits (DSCs), memory, and a processing module. A DSC drives a first signal via a single line coupling to a touch sensor and simultaneously senses, when present, a second signal that is uniquely associated with a user. The DSC processes the first signal and/or the second signal to generate a digital signal that is representative of an electrical characteristic of the touch sensor. The processing module executes operational instructions (stored in the memory) to process the digital signal to detect interaction of the user with the touch sensor and to determine whether the interaction of the user with the touch sensor compares favorably with authorization. When not authorized, the processing module aborts execution of operation(s) associated with the interaction of the user with the touch sensor. Alternatively, when authorized, the processing module facilitates execution of the operation(s).
