Efficient Visual Cryptography Technique for Image Security

Abstract

In today’s generations information acts as crucial role in every organization. Most of the organizations spending lots of amount just to protect the data due to increasing of cyber threats. We must provide the security to these confidential data before transmitting into network and while storing data in cloud storages. To provide the security to visual information from unauthorized persons we need to convert original information to unreadable format. So, to get this unreadable format we have a technique called as visual cryptography. Visual cryptography is a powerful technique for dividing a secret image into two or more number of shares also called as encryption and these shares are decrypting using the human visual system (HVS) without any computational method. In our proposed model first, we will apply visual cryptography to input secret image for generating shares (dotted image). We have generated 10 shares for secret image after that implemented Secured ECC cryptography algorithm for securing shares. These shares will send to receiver through transmitting carrier. Also, our model was analysed with evaluation parameters which is (Peak Signal to Noise Ratio(PSNR) and Mean Square Error (MSE).
