Visual Cryptography and Image Processing Based Approach for Secure Transactions in Banking Sector

The use of computers and Internet has become so pervasive so it influences all the banking sectors. Security has become the most important aspect in today's banking transaction system because banks are committed to provide secure core banking services to their customers. To achieve this goal authenticity of the users is required i.e. only the authorized users can take part in the transaction. Regarding this purpose banks uses Biometrics based authentication systems but due to unavoidable malicious activities database of the banking system is no longer secure. Smart hackers can fetch biometric details of customers from the bank's database and later can use it for fake transactions. To avoid all this catastrophic things Visual cryptographic technique is used. Visual Cryptography is an efficient encryption scheme in which information hide inside the images and decrypted only by human visual system. In this paper we propose a secure XOR operation based visual cryptography and image processing technique to secure banking transaction. Here we consider the case of joint account operation.
