Smart joint bank locker operation using visual cryptography

Abstract

Security has become the foremost vital facet in today’s banking system. As a result, banks are committed to give secured banking services to their customers. Considering the case of a joint bank locker operation, it needs a master key owned by the bank to open the vaults along with the key the customers have. To avoid using the manual operation of keys, a visual cryptographic scheme is proposed to operate the vaults using shares. Visual cryptography (VC) hides the details of the image used as a key by generating shares. Image steganography embeds the shares with a cover image, which ensures secure storage of the shares. A completely secured smart joint bank locker operation using a single share owned by the bank is introduced. The shares generated by the bank for different customers are put together to create a unique share to open all the vaults. The proposed approach guarantees not only absolute security than the traditional locker operation but also helps bank a simplified way of maintaining lockers key.
