Enhancing Security of Banking Locker System Using Secret Sharing Scheme Based on Random Grids

Abstract

Now a day's security plays key role in every manner. As every system is becoming automated security is must. In today's worldwide computer network environment exact and secure data transmission is very much essential. In this paper, a new approach is proposed to improve the security of banking locker system. This system will enhance the security of automated banking locker system using visual cryptography. Visual Cryptography (VC) is a secret sharing scheme where a secret image is encrypted into the number of shares which independently unable to disclose information about the original secret image. The proposed system uses random grids based VC. The advantage of this scheme is no pixel expansion in reconstructed image and no need of a codebook. The proposed scheme enhances the security of banking locker system by distributing the secret between customer and bank employee and reduces the space complexity of database.
