Survey on Visual Cryptography Schemes

Prajakta Nikam | Dr. Kishor Kinage

Abstract: Visual cryptography (VC) is a encryption scheme used to share secret image. It encodes image into n shares. These shares are either printed on transparencies or are encoded and stored in a digital form. The shares can look as noise-like pixels or as meaningful images. Decoding does not require all n shares. These shares are printed on transparencies and stacking them top to each other reveal the secret image. In this survey paper, we present the readers a overview of visual cryptography scheme and different approaches of visual cryptography.
