Colour Extended Visual Cryptography based on MKGED

T. Anuradha, Dr. K. Usha Rani

Visual Cryptography is a technique used to protect image based secrets. In this work, encryption method based on Modified Kernel based Gaussian Error Diffusion (MKGED) for colour extended visual cryptography, for visual quality improvement. This work depends on two important parameters and they are cluster centre points m_k and pseudo covariance matrix Q_k. On analysis, it is found that the performance of our proposed system is much better than existing methodologies and is proved by Peak-to-Signal-Noise Ratio (PSNR) value, Normalized Correlation Coefficient (NCC) and Mean Square Error (MSE).

Keywords: Extended Visual Cryptography, Error diffusion, PSNR, NCC, MSE
