Enhanced Security Mechanism for ATM Machines

The project proposes the idea of an image base added security for ATM machines using Raspberry pi that will eliminate the unauthorized usage of ATM cards by person other than the owner. The basic idea of the system is that after insertion of the ATM card into the machine and after the card verification, his image is captured using the webcam in the ATM and then it is matched with the card owner's actual images already stored in the database. If the captured image matches with the stored images, it means he is the authorized user and moves to the next stage where he can enter the password to continue the transaction. When the stored image and the captured image don't match, it means that he is an unauthorized user and thus blocking his access. The system may also inform the actual owner of the card regarding the card misuse. This proposed system requires the account holders to train their faces to the system so that it can be stored and used later. Once the person's image associated with the card is obtained from the database, further processing can be done on the proposed system itself, which does not affect actual server capacity. Also the proposed system can make use of the existing cameras on ATM machines for capturing the images which further reduces the implementation cost. Therefore this project proposes a simple, cost-efficient method which provides added security for ATM transactions against unauthorized card usages.
