An ATM is an electronic device that allows the customer of a bank to make cash withdrawals and check the balance of their account at any time without the need of a cash machine. Many ATMs also allow you to deposit cash or checks, transfer money between your banks. The first ATM in the world was installed in the city of ENFIELD in London on June 27, 1967 by Barclays Bank. ATMs are known by several other names, including automated transaction machine, automated banking machine, ATM (in Britain), money machine, bank machine, ATM, hole in the wall, Bancomat (in several countries in Europe and Russia), Multibanco (after a registered trademark, in Portugal) and Any Time Money (in India).
An ATM or cash machine (ATM), also known as an automated banking machine (ABM) in Canada, and an ATM (which is a registered trademark of Lloyds TSB), ATM or sometimes a hole in the wall In British is a computerized telecommunications device that provides customers of a financial institution access to financial transactions in a public space without the need for a cashier, human employee or bank teller. ATMs are known by several other names including the ATM, the automated banking machine, and several regional variants derived from trademarks in the ATM systems held by private banks.
Introduction of ATM security features
Several protocols are used to transfer information through the network at the ATM. Some of them are explained briefly:
1. TCP (Transmission Control Protocol):
- Protocol oriented to the connection.
- TCP is used to dynamically adapt to the properties of the internetwork and be robust to deal with any failure.
2. Simple Mail Transfer Protocol (SMTP):
- Simple ASCII protocol, accepts incoming messages and sends them to appropriate locations.
3. X.25:
- It is a standard, connection-oriented network protocol.
- Provides flow control.
4. Simple Network Management Protocol (SNMP):
- Used when entering information through the keyboard Since most ATMs are open for 24 hours and also all of them are not protected, it is important to provide security to the machine. Here we explain one of the technologies.
The Electronic Signature Lock (ESL) is a patented technology that can be implemented in hardware, firmware or software and is used to protect digital resources, funds transfer or physical access. You can identify the users of the computer terminal locally or remotely without having to modify or attach anything to the terminal. It is completely transparent to users and can be used surreptitiously without their knowledge and even identify them in a unique way. The ESL is associated or integrated into the protected resource, such as a computer or ATM. It will identify users of local or remote terminals as impostors even though they know all passwords, access codes and protocols to access protected resources, if they are not who they claim to be, as if their fingerprints were taken remotely and subtly. Facial recognition or fingerprint recognition are also the techniques used for the security of an ATM. In these techniques the related data are stored in the database :
1. Modern ATM physical security focuses on denying the use of money within the machine to a thief or fraud using some fraud detection techniques.
2. The customer requests a withdrawal from the machine that does not distribute money, but simply prints a receipt. The customer then takes the receipt to a seller and exchanges it for cash.
3. An additional security measure limits the total amount of ATM withdrawal to a certain amount.
4. This is intended to reduce the amount of fraud withdrawal.
