2. A LoRa-wave sensing information-security process to protect against unauthorized objects on an automated teller machine (ATM) comprising the steps of:
transmitting, by a LoRa modulator using a spread-spectrum modulation technique, a slot chirp signal to an ATM card slot and a keypad chirp signal to an ATM keypad;
receiving, by the LoRa modulator, a card-slot signal pattern of the slot-chirp signal rebounding off of the ATM card slot and a keypad signal pattern of the keypad-chirp signal rebounding off the ATM keypad;
providing, by the LoRa modulator to a sensor, the card-slot signal pattern and the keypad-signal pattern;
detecting, by the sensor, a first disrupted signal for the card-slot signal pattern if a skimmer is on the ATM card slot;
detecting, by the sensor, a second disrupted signal for the keypad-signal pattern if a fake keypad is on the ATM keypad; and
disabling, by the comparative analyzer, the ATM if the skimmer or the fake keypad is detected, or otherwise, allowing the ATM to continue to be in service.
