Pin Entry and Authentication Processes

Entering a pin code on a cash machine pin pad is a multi-step process that involves both user input and the cash machine’s internal verification mechanisms.

Firstly, the user inserts their card into the card slot, enters their pin code (which is typically a 4-digit or 6-digit number), and then confirms their interaction with the machine either by pressing an enter button or tapping an “okay” button. Meanwhile, the ATM sends a request to the bank’s central processing unit (CPU) to verify the entered PIN code with the actual PIN stored in the user’s account.

Algorithms Used for PIN Verification

The ATM’s CPU uses a combination of algorithms to verify the PIN code entered by the user. The most common algorithms used are the One-Way Hash Algorithm (OWHA) and the Hash-Based Message Authentication Code (HMAC). These algorithms are specifically designed for PIN verification to ensure the integrity and confidentiality of the user’s data.

Here are the steps involved in PIN verification:

The ATM’s CPU takes the entered PIN code as input and passes it through the OWHA/HMAC algorithm.
The algorithm generates a unique digital fingerprint, which is then compared with the stored hash value (obtained from the user’s account) in the ATM’s database.
If the digital fingerprint matches the stored hash value, the CPU generates an “authentic” signal indicating that the entered PIN is correct.
If the digital fingerprint does not match, the CPU generates a “non-authentic” signal, prompting the user to re-enter their PIN code.

Role of the Cash Machine Computer in Processing the Transaction

The cash machine computer plays a crucial role in processing transactions by acting as an intermediary between the user’s account and the bank’s CPU. The computer ensures the security and integrity of the transaction by verifying the entered PIN code and checking for any inconsistencies in the user’s data.
