| Abstract: | Visual cryptography(VC)is an encryption scheme for sharing secret images.Compared with traditional cryptography,it has the advantages of simplicity,security and concealment.The encryption is to encode the image for sharing,and to print the sharing on a transparent film or store it in digital form;the decryption process is to superimpose the sharing,and then realize it through human visual ability.This article introduces the basic concepts of visual cryptography and various different visual cryptography schemes,as well as the technology used in each scheme.In addition,the application of visual cryptography in different fields is explained. |
