Patent attributes
An automated teller machine (ATM) receives a first set of signals from components of the ATM. The first set of signals includes intercommunication electrical signals between the components of the ATM and electromagnetic radiation signals propagated from the components of the ATM. The ATM extracts baseline features from the first set of signals. The baseline features represent a unique electrical signature of the ATM. The ATM extracts test features from a second set of signals received from the component of the ATM. The ATM determines whether there is a deviation between the test features and baseline features. If the ATM detects the deviation, the ATM determines that the ATM is associated with a particular anomaly that makes the ATM vulnerable to unauthorized access.
