A Survey on enhancing visual cryptography using natural shares

Rekha Sarawade, Ashish Manwatkar


In visual cryptography reducing the pixel expansion and improving the display quality of recovered images are still major issues. Secret images are covered in shares by using conventional visual secret sharing schemes (VSS). Shares can appear as meaningful images or noise like pixels; but transmission of such a shares increase difficulties. In this paper we have propose survey on natural image based visual secret sharing scheme (NVSS). In this carrier image is using to recover the secret image and protect the participant during transmission phase. So we can hide the noisy shares and also propose possible ways to reduce the transmission risk problem for the shares.
