Abstract -
Color visual cryptography (VC) is a secret sharing scheme which uses to encrypt a secret message into n halftone image shares. The users can recover the secret image by stacking their shares, and then secret image can be revealed. In extended visual cryptography, the share images are constructed to contain meaningful cover images. Halftoning and visual information pixel (VIP) is the important feature, which provides immunity at the early stage of cryptography. In this paper we make a rumination of various error diffusions and visual information pixel (VIP) synchronization techniques to generate meaningful color shares with high visual quality and compare the respective algorithms for parameters such as PSNR and perceived error.
