Optimal Contrast Grayscale Visual Cryptography with Modified Multi-secret Sharing for Secure Application

TLDR: This paper proposes a technique of encode the password of a customer by improved Steganography, which is able to utilize at most all eight adjacent neighbors so that imperceptibility value grows bigger.

Abstract: Core banking is a set of services provided by a group of networked bank branches. Bank customers may access their funds and perform other simple transactions from any of the member branch offices. The major issue in core banking is the authenticity of the customer. Due to unavoidable hackingof the databases on the internet, it is always quite difficult totrust the information on the internet. To solve this problemof authentication, we are proposing an algorithm based onimage processing, improved steganography and visual cryptography. This paper proposes a technique of encode the password of a customer by improved Steganography, most of the steganographic techniques use either three or four adjacent pixels around a target pixel whereas the proposed technique is able to utilize at most all eight adjacent neighbors so that imperceptibility value grows bigger.and thendividing it into shares. Total number of shares to be created isdepending on the scheme chosen by the bank. When two sharesare created, one is stored in the Bank database and the otheris kept by the customer. The customer has to present the shareduring all of his transactions. This share is stacked with the firstshare to get the original image. Then decoding method issued to take the hidden password on acceptance or rejection of the output and authenticates the customer.
