A systematic review on visual cryptography system for security of image
Keywords:
visual cryptography,Shares,EncryptionAbstract
Visual Cryptography is a secure and unique image encryption technique which protects image based secret.
In visual cryptography image is encrypted into shares and in decryption process all or some of shares are super imposed
with each other to decrypt the original secret image. In this technique no complex computation is needed for decryption of
secret image which is the best advantage of Visual Cryptography Scheme. In this survey paper in this proposed system (N, N)
VCS is used for encryption.
