Identification in touch systems

A touch sensor system comprising:

• a plurality of touch sensors;
• a plurality of drive-sense circuits operably coupled to the plurality of touch sensors, wherein:
• when enabled, a first drive-sense circuit of the plurality of drive-sense circuits is configured to:
• drive a first signal via a single line coupling to a touch sensor of the plurality of touch sensors and simultaneously sense, via the single line, the first signal and, when present, a second signal coupled to the touch sensor of the plurality of touch sensors, wherein the second signal is uniquely associated with a user;
• and
• process at least one of the first signal or the second signal to generate a digital signal that is representative of an electrical characteristic of the touch sensor of the plurality of touch sensors;
• when enabled, a second drive-sense circuit of the plurality of drive-sense circuits, configured to:
• couple the second signal to the user via a drive-sense circuit interface that includes at least one of a pen, a conductive mat, a seat, a seat belt, a cell phone, a smart phone, a key fob, a watch, an active wrist-band, a personal digital assistant (PDA), or a clip-on element;
• memory that stores operational instructions;
• and
• a processing module operably coupled to the first drive-sense circuit of the plurality of drive-sense circuits and to the memory, wherein the processing module when enabled, is configured to execute the operational instructions to:
• process the digital signal to detect interaction of the user with the touch sensor;
• determine whether the interaction of the user with the touch sensor compares favorably with authorization;
• and
• based on unfavorable comparison of the interaction of the user with the touch sensor with the authorization, abort execution of one or more operations associated with the interaction of the user with the touch sensor;
• and
• based on favorable comparison of the interaction of the user with the touch sensor with the authorization, facilitate execution of the one or more operations associated with the interaction of the user with the touch sensor.

A method for execution by a touch sensor system, the method comprising:

• via a drive-sense circuit of a plurality of drive-sense circuits operably coupled to a plurality of touch sensors, driving a first signal via a single line coupling to a touch sensor of the plurality of touch sensors and simultaneously sensing, via the single line, the first signal and, when present, a second signal coupled to the touch sensor of the plurality of touch sensors, wherein the second signal is uniquely associated with a user;
• processing at least one of the first signal or the second signal to generate a digital signal that is representative of an electrical characteristic of the touch sensor of the plurality of touch sensors;
• processing the digital signal to detect interaction of the user with the touch sensor;
• determining whether the interaction of the user with the touch sensor compares favorably with authorization;
• and
• based on unfavorable comparison of the interaction of the user with the touch sensor with the authorization, aborting execution of one or more operations associated with the interaction of the user with the touch sensor.
