Abstract: The day to day advancements in science and technology resulted in enormous data transaction and demand for secure communication and e-banking are not an exception. The usage of ATMs for cash withdrawal and other transaction related works is massive. Looking at the elements required by a customer for ATM utility, the debit card and secure PIN are being sent separately by postal service to the customers of many banks for increased security. However, tampering is always possible because of the unique mode of sending the both card as well as PIN authentication to the customers. Here we suggest an alternative method to enhance the security with respect to debit card and PIN communication to the customers with LabVIEW based transform domain steganography approach where the PIN will be hidden in the scanned Debit card image with the help of Discrete Cosine Transform (DCT) and swapping algorithm. This transformed image will be e-mailed to the customers. Proper retrieval algorithm will be used by the concerned customers to reveal the secret PIN authentication. Histogram report, error metrics like MSE and PSNR have also been discussed in this study for sample ATM debit card image.
