Embedded visual cryptography for secure transmission of bank cheque

Today, banking system has carried banking for the customer's expediency, supporting set of services, where authentication plays a vital role. Due to the fabulous apprehension and growth in the field of hacking, that it is not safe to rely on web to accumulate all the information. So in order to beat this problem we have proposed an efficient algorithm for secured bank cheque authentication by Embedded image Cryptography scheme. It is a cryptographic approach that uses visual information as input, encryption and decryption is done by using human visual system. The proposed method Embedded Visual Cryptography Scheme (EVCS) uses gray threshold with morphological operation for secure transmission of bank cheque over the network. In this approach first apply gray threshold with morphological operation and divide the input image into different number of secret share images using traditional visual cryptography technique. Embed the each share into different cover images. Finally, stack the embedded images to get the original information of images. The performance of proposed method is calculated by using PSNR, UQI and MSE Value. The proposed EVCS shows the high performance in terms PSNR, UQI and MSE for secure transmission of bank cheque over network.
