METHOD, DEVICE, SENSOR AND ALGORYTHM FOR DETECTION OF DEVICES STEALING INFORMATION FROM ATM DEVICES

摘要

Method for detection of skimming devices comprising detecting electromagnetic emissions by sensors of the invention located inside of ATM. Electromagnetic emission is monitored in broad band of 10kHz to 30MHz and narrow band, and only one determined frequency is passed through filters in the narrow band, and sensors' output is analyzed and processed according to algorithm of the invention. Alarm signal is generated upon achieving pre-assigned threshold chosen so that discriminating between useful signal and interference is not obstructed. The method is implemented by device comprising sensors for detecting electromagnetic emissions, microcontroller for controlling the sensors, master microcontroller for processing of sensors' output, and notifying module for sending signals to control center. According to the invention sensor is provided for detecting electromagnetic emissions comprising receiving, regulating, filtering and converting parts.
